The testing plan for the U.S. Air Force’s sixth-generation F-47 fighter is continuing to take shape ahead of the type’s expected first flight in 2028. The Air Force Test Center (AFTC) aims to blend developmental and operational test elements, and leverage new tools in the virtual realm, to help accelerate that work. All of this is in support of an aggressive program schedule that aims to see the first production F-47s enter operational service in the early 2030s.
Air Force Brig. Gen. Mark Massaro, head of the AFTC, was asked about how the groundwork is being laid for F-47 testing during a virtual talk the Air & Space Forces Association’s Mitchell Institute for Aerospace Studies hosted yesterday. AFTC is located at Edwards Air Force Base in California, which is the Air Force’s main flight testing hub.
“So, I’ll leave timelines to the [F-47] program office and other folks to talk to, but what I will tell you are some of the things that we’re doing to accelerate our test capabilities to get critical capabilities out the door,” Massaro explained. “Integrated test is a key component.”

“So, how we mix together the DT [developmental test] and OT [operational test] elements, how we bring our operational test partners in earlier to define the requirements early on in the test planning process,” he continued. “We understand that the information that we can get early on in a program may have applicability to that final operational test requirement to establish whether it’s effective and suitable to the end user. So that’s a key component to accelerating test capabilities.”
There has always been overlap in development and operational test efforts for new U.S. military aircraft, but the Air Force has been taking steps to more deeply integrate these processes in recent years. The F-15EX Eagle II fighter, which reached initial operational capability in 2024, was the first ever Air Force aircraft to be fully tested and fielded through DT and OT efforts conducted in parallel, as you can read more about here. The service has more recently applied these concepts to the B-21 Raider program with test flights where developmental and operational test pilots have shared the cockpit.

“Another thing that we’ve learned over time too, if you think back to software testing and you think about agile software development, is having an iterative capability that you constantly iterate on,” Brig. Gen. Massaro also highlighted yesterday. “So, thinking about how we can structure our software, or our software testing, our capabilities testing.”
In this way, “we have those opportunities to inform decision makers on a regular cadence on what type of capability they may have at a certain timeline to be able to issue out to a warfighter on a time that might not be a normal milestone chart,” he continued. “We’re really working to incorporate into our test planning processes.”
“Another thing – and I kind of alluded to it a little bit earlier, too – is on the digital front, using our software tools, that super intelligence, graphic processing units, which have a significantly higher capability to process information, to really refine model iteration,” the AFTC head added. “Those models and flight test data [can be used] to update things like computational fluid dynamics when you’re doing tests like loads and high-alpha maneuvering to get information quicker from a flight test back into the program.”
Those “digital tools” can also be used “to accelerate how that information then goes back into a design choice or change if they need to make it,” he continued. “Coming up with those opportunities to use those tools in a test design and in a program” can then further help “to accelerate that final schedule delivery.”

Even very high-fidelity modeling in the digital realm is still not a substitute for real-world flight tests. However, Brig. Gen. Mark Massaro spoke more generally yesterday about how AFTC has been blending digital and live testing to maximize their respective benefits.
“We use models to develop our capabilities, and we need to anchor those models in truth, in physics, and an understanding of what happens in the real world,” the AFTC head stressed. “Outside of a cyber system, all of our capabilities touch the real world and touch physics, and we need to understand those dynamics. So, the models that we use to do design work, to do iterative type[s] of developmental work, and, in ways, operational work, too, need to be anchored in that real world truth.”
At the same time, “we can’t replicate what we need to go and test, and develop tactics and operationally test, in the real world on some of our ranges,” he also noted. “So, from a geographic perspective, just the width and the depth and the height of the ranges to the laydown of the systems that we have to see on the ranges to be able to execute against a threat, [and] the numbers that we might have to be testing.”
Blending real and virtualized elements can therefore be very valuable.
An “element that we’ve done in the developmental world for quite a while, that are [sic] part of this conversation, are plugging in, even though it’s a virtual environment, plugging in real world hardware into that virtual environment,” Massaro offered as one example. “So, you’re getting real-world software, the OFPs [operational flight program software], or you’re getting real-world sensing information coming into that virtual environment and feeding it there.”
Virtualized elements can also be added to real-world flight test events in various ways. The Air Force, among others, is also making use of these so-called live, virtual, constructive (LVC) concepts for training purposes for many of the same general reasons, including limited range capacity.
It is also worth noting here that the F-47 program is already benefiting from years of flight testing in secret using full-scale demonstrator aircraft. A substantial amount of simulation and modeling would also already have been done as a byproduct. A simulator likely already exists, as well, which could be used for risk reduction and fine-tuning of the F-47 design, as well as testing flight dynamics.

Though much about the F-47 program remains highly classified, the Air Force has consistently said that the program continues to be on track. Prime contractor Boeing is now building the first flying example, and construction is already well underway to establish a full production line. As mentioned, the target date for a first flight is currently in 2028, ahead of operational fielding in the early 2030s. As an aside, Boeing has also now won the contract to develop the Navy’s sixth-generation carrier-based fighter, currently referred to as F/A-XX.
AFTC is doing its part now to be ready to support the flight testing that will be needed to keep the F-47 program on track in the coming years.
The African Union (AU) on Wednesday launched a continental credit rating agency aimed at providing risk assessments that it says will be more credible and realistic than those produced by the major international rating agencies. The goal is to lower Africa’s borrowing costs and support the continent’s development and industrialization. To that end, the African Credit Rating Agency (AfCRA), which will be headquartered in Port Louis, the capital of Mauritius, will operate as a private and independent entity, with no ownership stake held by the AU or any government.
O circo da Fórmula 1 vai chegar amanhã a Marina Bay para a disputa do GP de Singapura, 17ª etapa da temporada 2026 no fim de semana.
As atividades em pista decorrem entre sexta-feira (9) e domingo (11), com o formato Sprint e a tradicional corrida noturna da Fórmula 1 nas ruas da cidade de Singapura. Também designado de Singapore Street Circuit, é um percuso de rua localizado na baía da Marina e tem 5,2 kms de extensão.
O aspecto mais singular, que não deixa de ser interessante, prende-se com o fato desta ter sido a primeira corrida na história da Fórmula 1 a ser realizada à noite. O circuito totalmente iluminado deu aos pilotos um desafio adicional com o qual tiveram de aprender a lidar. Outro aspeto: esta corrida realiza-se no sentido retrógado (contrário aos ponteiros do relógio). Enfim, pormenores que diferenciam esta prova na Ásia das demais no resto do mundo.
Quanto a treinos, na sexta-feira realiza-se o único treino livre do fim de semana, começa às 09:30 hrs (horário de Portugal), enquanto a Qualificação Sprint será realizada a partir das 13:30 hrs.
No sábado, a corrida Sprint tem a largada agendada para as 10:00 hrs e a Classificação para definir a grelha de partida para o Grande Prémio começa às 14:00 hrs.
A corrida principal, correspondente ao GP de Singapura, será disputada no domingo, com a largada a ocorrer às 13:00 hrs, sempre pelo horário de Portugal (GMT+0).
Como habitualmente acontece, com a colaboração da F1Mania, dar-lhe-emos aqui no diariOnline Região Sul, o essencial da informação, desde treinos livres, classificações e corridas, naturalmente.
Before the hasty and unexpected departure of the bombers on Sunday, B-1s had been deployed to RAF Fairford continuously since March, initially in support of Operation Epic Fury against Iran. A contingent of B-52s had also conducted strikes on Iran from Fairford, but left back in July. The base is a major operational hub for the U.S. military in the United Kingdom, and regularly hosts strategic aircraft, including bombers and U-2 spy planes.
Dan Rivers, U.S. correspondent for ITV News in the United Kingdom, was among the first to report on Monday that the B-1’s quick departure had been prompted by concerns about a potential Spiderweb-like drone attack ordered by Iran, citing an unnamed source. Other outlets have subsequently reported similar details, all sourced to anonymous U.S. and British officials.
“They didn’t fly out by accident,” U.S. President Donald Trump told reporters during a gaggle at the White House on Monday when asked about why the B-1s had left Fairford. “There were some threats.”
“I can’t tell you that, but if they did, they’ll suffer greatly,” Trump added in response to a separate question about whether Iran might have managed to get weaponized drones into the United Kingdom.
“What you saw there was the Secretary of War [Pete Hegseth], out of an abundance of caution, trying to protect our guys,” U.S. Vice President J.D. Vance said during a separate press engagement on Monday. “We do feel, with some confidence, that the Iranians are – they’re trying to do what the Iranian state has done for 49 years, which is engage in acts of terrorism against the United States, and a lot of other people, as well. So, we are being extremely cautious.”

“We’ve documented what happened [near Fairford] last week. I wouldn’t just directly tie that to the move that was made,” U.S. Secretary of State and National Security Advisor Marco Rubio also told members of the press on Monday. “The only reason why you guys are focused on how many planes are at Fairford is because of the threat that happened last week.”
“We have confidence in the security of all of our bases, because all of our bases are [sic] theoretically could be threatened at any moment,” he added.
Rubio’s comments notwithstanding, the remarks from Trump and Vance make clear that there was some recent threat intelligence that contributed to the decision to pull the bombers from Fairford. There are still many questions about the exact nature of the potential attacks, and how imminent, or not, the danger may have been.
Regardless, as mentioned, the prospect of a near-field drone attack on a base like Fairford carried out by actors in close proximity is extremely plausible, and the barrier to entry to such an operation is relatively low. Spiderweb may have thrust this reality into the public consciousness in dramatic fashion, but the danger well predates that operation, and even the start of Russia’s all-out invasion of Ukraine in 2022.
TWZ has been highlighting exactly these kinds of threats in the course of a decade or so now of regular reporting on drone incursions over U.S. and foreign military facilities and critical infrastructure, as well as American naval vessels operating offshore. Langley Air Force Base in Virginia and Barksdale Air Force Base in Louisiana, some of America’s most strategic airbases domestically, are among the facilities that have had to grapple with this in the past. After the Langley incident, in particular, it had become clear to the larger public what we had been reporting for many years, that the United States does not control the airspace over even its most critical military installations.

A drone attack on Fairford would also not necessarily have had to come from somewhere very close by. Longer-range one-way attack drones are steadily proliferating, and can be launched using a variety of methods from positions on the ground, as well as vessels at sea. TWZ explored the very real threat of sea-based drone attacks, including ones conducted covertly, and Iran’s specific ability to carry them out globally, following the leak of an FBI alert back in March.
The proliferation of lower-end one-way-attack drones has ‘democratized’ precision-guided attacks, even for non-state actors. The fielding of automated targeting capabilities, driven by developments in artificial intelligence and machine learning, is also becoming more and more widespread. That technology will soon enable these weapons to find and strike even moving targets on their own. Even without anyone at the controls and without the drone putting out any detectable radio emissions, very effective precision attacks can still be launched at static targets, like known parking areas for aircraft at airbases, just by using basic map coordinates or Google Earth. It’s also worth pointing out here that the definition of a stand-off attack is becoming increasingly blurry, with even quadcopter-type drones capable of flying miles away to conduct a kamikaze attack on a target based on a set of GPS coordinates.

Overall, it is an indisputable fact that aircraft sitting exposed on a flightline are particularly vulnerable to drone attacks, as well as other threats. This is something U.S. military officials have acknowledged themselves. Fairford, where B-1s and other bombers have no option but to park out in the open in well-established areas that are plainly visible from outside the base’s immediate perimeter, is indicative of how American military aircraft are generally positioned on the ground abroad and at home.
As we wrote all the way back in 2017:
“Similar swarming strikes could be unleashed behind the front lines as well, with hugely expensive and low density/high demand combat aircraft being especially vulnerable to this sort of tactic—something General James Holmes alluded to inadvertently while speaking to the Air Force Association, stating:
‘Imagine a world where somebody flies a couple hundred of those and flies one down the intake of my F-22s with just a small weapon on it.’
Actually, it would be even easier to just strike the jets as they sit idle and vulnerable on the flight line. One swarm could see a whole squadron of tightly packed fighters destroyed without even having a chance to fight back.”

“I’m not a big fan of hardening infrastructure,” Gen. Kenneth Wilsbach said at a roundtable at the Air and Space Forces Association’s main annual symposium in 2023, offering a prime example of this viewpoint. “The reason is because of the advent of precision-guided weapons … you saw what we did to the Iraqi Air Force and their hardened aircraft shelters. They’re not so hard when you put a 2,000-pound bomb right through the roof.”
Wilsbach was commander of Pacific Air Forces (PACAF) at the time. He subsequently became head of ACC and is now Chief of Staff of the Air Force, the service’s top officer.
“I think that I don’t want to spend a lot of money on hardening shelters. Unless you’re going to send something 100 feet or more underground, we can blow it up, and so can they,” Wilsbach said in an interview with Breaking Defense in July of this year when asked explicitly if his position changed. “So, the economics of building a shelter that is impervious to a strike doesn’t work.”
U.S. Air Force Chief of Staff Gen. Ken Wilsbach speaks during an all-call with personnel at RAF Mildenhall, another base in the United Kingdom, on July 13, 2026. USAF
“I think the economics favor defending your airspace, defending your ground space with systems that can defeat the incoming rounds, versus building a shelter,” he added. “Some people would argue, well, you should do both. Well, that’s even more expensive. And the other thing is, the shelter doesn’t go anywhere.”
It is fair to point out that typical above-ground hardened aircraft shelters are not invulnerable, especially to attacks involving ballistic, cruise, and certain air-launched threats. There are also substantial cost and other factors to consider when it comes to any major military construction effort.
That being said, having more hardened infrastructure also imposes costs and complexities on opponents, who have to dedicate more advanced and costly munitions and other resources to ensure targets are neutralized. Shelters have the knock-on benefit of complicating the targeting process for an enemy by obscuring where aircraft are or are not positioned, to begin with. An opponent has to treat shelters like they are full even if they are empty.
When thinking about hardened aircraft shelters, stereotypical Cold War-era reinforced concrete structures typically come to mind. However, they do not all have to be built to a one-size-fits-all standard with the same degree of hardening across the board to be useful. Shorter-range drone attacks are typically carried out by platforms carrying small explosive charges or that are designed to drop small bomblets. Even longer-range one-way-attack drones generally have smaller warheads than traditional missiles, they also hit with less kinetic energy.

A structure that shields against smaller blasts and shrapnel, also including from cluster munitions that can be readily scattered across wide areas, is one that then has to be addressed by more capable weapons. This could even include mobile or otherwise temporary shelters that offer sufficient concealment and protection.
This picture shows what the Air Force described as a “prototype portable camouflage, concealment, and deception hangar” in use during Exercise Hoodoo Sea in 2023.

Eliminating, or at least substantially mitigating, the lowest rung of threats creates a dilemma for opponents, who then have to decide whether it is even worthwhile to attempt certain types of attacks. There is clear value in narrowing the available options for the enemy and pushing them toward having to expend higher-end, more expensive munitions, that are available in smaller quantities, and that traditional active defenses may be better optimized to handle. As an example, it may be more viable to shoot down a small barrage of incoming cruise missiles than a swarm of dozens of drones.
There are magazine and stockpile depth issues at play here, too. This is something that has also been brought front and center by the conflict with Iran, which has fueled already long-standing concerns about the sufficiency of stockpiles of air defense interceptors, other critical munitions, and the capacity to replenish them quickly. This is something the British government, among others, is also grappling with, as you can read more about in our separate reporting here.
Furthermore, losses of aircraft on the ground are not without their own costs, which are even more lopsided if an opponent can simply use lower-cost weaponized drones. U.S. bombers are particularly expensive and prized assets that are in short supply compared to the level of demand, as seen during the height of combat operations earlier this year against Iran. When it comes to B-1s, specifically, there are only 45 of them left in service today. A dozen of them being knocked out in one go would have major repercussions strategically. Losing even one would also be a propaganda coup for whoever might be responsible.
How many shelters can we build for the upgrade cost of one Zumwalt class DDG that will probably be parted out in 10 years anyway?
On top of all this, the U.S. military simply will not always have the luxury of being able to rapidly relocate aircraft in response to threats. Moving a dozen bombers on short notice takes massive resources. It is not just aircraft that have to be repositioned, but supporting personnel and assets, as well as weapons and fuel. Having to shift to alternate locations could easily have negative impacts on tempo and other aspects of operations, especially in the midst of actual conflict. RAF Fairford is one of only a few bases globally that can support bomber operations for a prolonged period.
“There is value in some light protection against small, unmanned threats,” Gen. Wilsbach also told Breaking Defense in July. “Some of them — just nets that are up that keep a small, few-$100 drone from getting next to a $2 billion aircraft. That actually works, [and is] really cheap.”
A graphic included a contracting notice put out by authorities at Langley Air Force Base in 2024 showing how sunshade-type shelters at the base might be equipped with anti-drone nets. USAF
“It’s not either or,” Wilsbach said in a separate interview with Air & Space Forces Magazine in July. “The net keeps the small UAS [uncrewed aerial system] from getting close to an aircraft that you’re trying to protect… That’s a very inexpensive way to give you some modicum of protection without killing your checkbook on really exquisite defensive systems.”
In spite of these institutional developments, action to implement such recommendations on a broad basis has continued to lag. There still does not appear to be any major department-wide push to build new hardened aircraft shelters or other fortified structures at facilities globally. The U.S. Air Force does have a certain number of hardened aircraft shelters at bases now, especially in the Pacific and Europe.
This is all despite a very visible trend in the construction of new aircraft shelters and other hardened infrastructure elsewhere around the globe, including in China, Russia, North Korea, and Iran. Even before Operation Spiderweb, Russia had already initiated a large-scale effort to build new hardened shelters at various bases, especially on the occupied Crimean Peninsula, in the face of expanding Ukrainian drone and missile attacks. This effort has now extended to building the huge hardened shelters for the country’s bomber force, something the country has never done before.
“It is inappropriate to discuss matters of intelligence, and we will not discuss specific force protection measures,” a U.S. Air Force spokesperson told TWZ yesterday when asked about the reports that Iranian drone threats prompted the recent removal of the B-1s from Fairford. “The Department will continue to assess the threat environment surrounding our installations and take appropriate actions to protect our people, our platforms and the bases where our forces operate from.”
We still do not know exactly how serious or imminent any recent threat to the B-1s at Fairford was that contributed to their hasty departure. Regardless, the reports of concerns about potential drone attacks remain very plausible. The reality here is that a dozen bombers were yanked from a forward operating location in Europe without an adversary ever having to fire a shot. This is a problem set that is only growing, especially as lessons and expertise on low-end weaponized drones from the war in Ukraine are spreading around the globe.

Erecting new aircraft shelters and other hardened infrastructure would not be a full solution to those threats by themselves. At the same time, they would be a valuable added layer of defense, and a passive one that would have a huge logistical footprint to operate once the initial investment is made. The lack of movement to better fortify American airbases globally is only becoming more and more glaring, and it remains to be seen if real action will not occur until lessons are learned in a most unfortunate way.
George Russell irá neste final de semana para o GP de Singapura de Fórmula 1 sabendo que irá tomar uma grande penalização. A Mercedes confirmou que após o abandono na Malásia, o piloto precisa de um novo motor e, assim, vai exceder o limite máximo permitido na temporada.
Para o britânico, o GP do Bahrein, em Sepang, foi mais um para esquecer, já que, quando estava na terceira posição, quase no final da disputa, viu-se obrigado a abandonar com problemas no motor.
Após a prova, Toto Wolff confirmou que foi o motor que provocou o abandono de Russell. Segundo o austríaco, a falha não terá ocorrido no período antes do safety-car, mas a Mercedes disse, segundo a F1Mania, que ainda precisaria avaliar melhor os motivos.
Resumindo, a equipa alemã confirmou que George Russell precisa trocar o motor para a próxima corrida da F1 neste final de semana, em Marina Bay, e por isso irá largar para a corrida na cauda do pelotão.
Esta situação representa mais um enorme golpe no campeonato do piloto, que já está mais de 80 pontos atrás do seu companheiro de equipa Kimi Antonelli, quando faltam sete etapas para o fim do campeonato.

Lows are expected to stay above averages overnight with a few lingering showers for Teller county while the rest of southern Colorado stays dry. Clouds will stick around for some overnight too before they clear into tomorrow.
Colorado Springs forecast: Low: 55; High: 81;
Lows will be at just about 55 degrees for Tuesday evening with a couple of clouds. Colorado Springs will stay dry for the rest of the week too. Highs will sit 10 to 15 degrees above averages through the end of the week as a high pressure ridge builds.
Pueblo forecast: Low: 55; High: 84;
Pueblo will see mid-50s overnight tonight too. Clouds will still stick around before they burn off throughout the late morning hours of Wednesday. The rest of the week will stay hot in the mid-80s in Pueblo with more sunshine and dry time. Saturday stays hot ahead of changes in Sunday and early next week with cooler temperatures and moisture.
Canon City forecast:Low: 56; High: 82;
Lows stay well above averages tonight with clouds lingering. Tomorrow will be just a few degrees cooler than today still with low to mid-80s in the forecast. The rest of the week stays hot and sunny with changes by Sunday and Monday.
Woodland Park forecast:Low: 48; High: 67;
Upper 40s are expected for Tuesday evening with a few stray showers lingering in Teller county. The rest of the week will stay in the upper 60s. By Sunday and into Monday and Tuesday, expect a major cool down with chances for rain with even a few snowflakes... More details to come.
Extended outlook forecast:
The changes we have been looking forward too still haven't arrived, but you can look forward to them by Sunday. Sunday will cool off to be slightly more seasonal across the area. Into Monday and Tuesday more moisture will be in our atmosphere so some showers can be expected for southern Colorado by then. Mountain snow will be likely by then too.

Overnight lows for Monday will be in the 50s for most. That means temperatures will be five to eight degrees above seasonal averages. Not much cloud cover is expected into the late-night hours either.
Colorado Springs forecast: Low: 54; High: 82;
Tuesday will be at about 82-degrees for afternoon highs. That sets up the Pikes Peak Region to be 12 or 13 degrees above seasonal averages. There will be some more clouds to give a little bit of a break from the heat during the afternoon. The skies stay dry and calm.
Pueblo forecast: Low: 53; High: 86;
Mid-80s are expected for Tuesday with more clouds and dry time. The rest of the week will be slightly cooler, but our high pressure ridge sticks around.
Canon City forecast: Low: 56; High: 84;
Highs for Canon City on Tuesday are similar to Pueblo in the mid-80s, which means things will be 10 to 15 degrees above where they should be. More clouds are expected too. West of Fremont count a few stray showers could be seen Tuesday afternoon.
Woodland Park forecast: Low: 48; High: 69;
Woodland Park will see it's hottest day on Tuesday too with highs in the upper 60s, but it will still be nice and dry for most of the day. I think by the dinnertime hours, a stray shower is possible on Tuesday in Teller county, but if we can squeeze any moisture out, it will be quick moving. Otherwise, clouds are expected.
Extended outlook forecast:
After the hottest day of the week on Tuesday, southern Colorado can expect slightly cooler temperatures through the rest of the week. Highs and lows will still sit about averages, but will drop by three to five degrees. Dry conditions with plenty of sunshine continue outside too. Saturday will see the same conditions. The next hint of changes arrive with a low pressure system likely to move in late on Saturday and into Sunday and Monday. Temperatures are expected to drop by then with likely some more moisture too. That pattern change will be something to watch while the October heat sticks around.

The U.S. Air Force’s scramjet-powered Hypersonic Attack Cruise Missile (HACM) has finally reached the flight test phase, with at least one “release” having been carried out so far over a range in Australia. HACM has suffered significant delays, and the Air Force has taken the risky step of scaling back overall testing plans to try to keep the program on schedule. The stated goal is to be able to make a decision to start rapidly acquiring HACMs in 2027.

“The U.S. Air Force, in partnership with Australia, has conducted a flight test of the Hypersonic Attack Cruise Missile (HACM) as part of our continuous work to advance long-range strike capabilities,” an Air Force spokesperson confirmed to TWZ today. “This effort is part of the Southern Cross Integrated Flight Research Experiment (SCIFiRE), a collaborative agreement built on more than 15 years of partnership between our two nations.”
“Leveraging this enduring alliance, the Royal Australian Air Force executed the release of a HACM flight test unit over a designated Australian test range, gathering crucial data to advance the program’s objectives,” the spokesperson added. “The flight was the culmination of an extensive series of tests designed to measure the missile’s performance under realistic flight conditions.”
The spokesperson did not name the test range where the “release” was conducted or say when that occurred. Whether the missile flew under its own power for any amount of time after release is unknown. What aircraft was used to carry the missile aloft is also not known. TWZ has reached out for more information.
The Air Force did say previously that it planned to conduct HACM launches in Australia. The expectation has long been that this would be done at the country’s sprawling Woomera Test Range, which provides an ideal location for extended-range flight testing activities in general. The U.S. and Australia have partnered on other hypersonic testing at Woomera in the past, as seen in the video below. The remote inland location of the range complex makes it well suited for conducting more sensitive tests away from prying eyes, as well.
The Government Accountability Office (GAO), a Congressional watchdog, has also reported in the past that RAAF F/A-18F Super Hornets would be used to conduct at least some of the HACM test launches. This would fit with today’s statement from the U.S. Air Force saying that it was the RAAF that “executed the release.” The Air Force’s initial launch platform is the F-15E Strike Eagle, though others are expected to follow.

To date, neither the Air Force nor Raytheon has released a confirmed picture or rendering of HACM. In 2023, the Air Force did release a picture, seen below, showing an air-breathing hypersonic cruise missile test article related to either HACM or the preceding HAWC effort.
USAF
“The missile consists of two stages, a rocket booster and a scramjet cruiser, which separates from the booster and eventually dives toward its target,” according to GAO. Scramjets do not function effectively at lower speeds, and designs powered by them require some form of initial boost to a high Mach velocity. Hypersonic speed is generally defined as anything above Mach 5, but what HACM’s peak speed might be is unknown.
Two-stage air-breathing missile-like hypersonic vehicle designs have been tested on several occasions in the past. This includes Boeing’s scramjet-powered X-51 Waverider and HyFly 2 hypersonic test vehicles, among others. The X-51 (as its name indicates) and HyFly 2 also notably had so-called ‘waverider’ configurations designed to ‘skip’ on the shockwaves generated during high-speed flight to help provide additional lift. Whether HACM might also use this principle is not known.
It’s also worth noting here that Castelion’s Blackbeard hypersonic missile also has a two-stage configuration. It remains unconfirmed whether or not the second stage of that weapon is powered, but it does not appear to be an air-breathing design either way. Castelion is currently developing an air-launched version of Blackbeard for the U.S. Navy, which is also in flight testing now, as well as a ground-launched type for the U.S. Army. You can read more about that missile here.
Scramjet-powered air vehicle designs, including aircraft and missiles, have historically proven challenging. As noted, HACM has suffered delays over the years. The original goal had been to begin flight testing in 2024, which slipped first to 2025 and then 2026.
“The HACM program is on track to conduct its first flight test in the second quarter of fiscal year 2026, but officials said there is effectively zero margin left in the schedule for the rapid prototyping effort. The program has already descoped the rapid prototyping effort from seven to five planned flight tests,” GAO said bluntly in a report published in July. “The Air Force plans to produce 13 missiles during the rapid prototyping effort, including test assets, test spares, and operational rounds.”
“If a significant flight test failure occurs, it is likely that the program will not be able to complete all five tests within the 5-year rapid prototyping timeframe,” the report continued. “According to the program, completing at least the first three flight tests is critical for informing the Air Force’s decision to initiate a rapid fielding effort and procure HACM in fiscal year 2027.”
GAO’s July report, which had a January cutoff date, noted later on that the Air Force’s target date for initiating the rapid fielding effort, more specifically, was the first quarter of Fiscal Year 2027. This fiscal period began last Thursday and runs through the end of the year. Whether the service is still aiming to keep to that part of the schedule is unclear, but it would seem extremely difficult to do so.

“The HACM program has taken on risk to maintain its current schedule. According to program officials, maintaining the schedule has required aggressively resequencing activities to focus almost exclusively on those necessary to support the first flight test date,” GAO’s report added. “In some cases, officials said this has involved risky strategies, such as concurrently performing parts validation testing while completing the system’s design, which could require the redesign of key parts if they fail validation testing.”

Regardless, the U.S. military, as well as its Australian counterparts, have made it clear in the past that they view hypersonic weapons as critical for success in future conflicts, especially high-end fights, such as one in the Pacific against China. In general, air-breathing hypersonic cruise missiles offer a valuable and highly flexible way to strike targets, especially time-sensitive ones, quickly and over extended ranges. The weapon’s high speed and maneuverability drastically increase its ability to penetrate through enemy air defenses and reduce the total time an opponent has to react.
Whether or not the Air Force will be able to avoid any more major delays with HACM remains to be seen. The service’s goal to start at least limited production of HACM before the end of 2027, if not sooner, is even more ambitious now after years of schedule slips. As mentioned, officials have already acknowledged there was no more margin for error at the start of the year. There are many questions still about what form any initial fielding will take, and how that might be further impacted by the truncated testing plan.
The HACM program has at least now hit the important milestone of beginning flight testing.
U.S. Customs and Border Protection (CBP) has retired the last of its P-3 Airborne Early Warning (AEW) aircraft. The AEW version is instantly recognizable from the saucer-like radar dome on top, as seen on other AEW types like the E-2 Hawkeye and the E-3 Sentry. CBP was the only operator of this variant of the P-3 Orion and is said to have been the only law enforcement agency to fly any kind of dedicated AEW plane. The retirement of these aircraft comes at a time when American AEW assets, in general, are under heavy strain by demands globally.
CBP officially retired its final P-3 AEW on September 30, 2026, after a final flight from National Air Security Operations Center Jacksonville (NASOC Jacksonville), in Jacksonville, Florida. CBP has also flown Long Range Tracker (LRT) variants of the P-3, configured for more traditional maritime surveillance missions. The current plans for the LRT aircraft, and whether their sunset may also be on the horizon, are not immediately clear, and TWZ has reached out for more information. Orions of all types have been steadily disappearing from service with the U.S. military and elsewhere across the U.S. government as the aging aircraft become more difficult to operate and maintain.
End of the Road: AMO’s Iconic P-3 Dome Takes Its Final Flight!
On September 30, 2026, the distinct silhouette of a four-engine turboprop carrying its massive rotating radar dome touched down for the final time at the National Air Security Operations Center in Jacksonville.
“Our Jacksonville-based P-3 AEW fleet has served as a cornerstone of America’s outer-layer border security,” according to a brief announcement from CBP about the retirement on social media. “Its crews flew far beyond our borders, providing wide-area surveillance across the Caribbean, Gulf of America [Gulf of Mexico], and the transit zones of Central and South America, helping detect and track threats before they could reach the United States.”
By all indications, including official CBP sources, the P-3 AEW fleet consisted of eight aircraft at its peak. There is a confusingly worded 2014 CBP press release that mentions an “11th and final Lockheed Martin P-3 Airborne Early Warning (AEW) aircraft overhaul,” but that figure looks to also include three of the six LRT versions. The same release says that CBP only had 14 P-3s of all types at that time.
What was then known as the U.S. Customs Service (USCS) first began operating the P-3 AEW version in the late 1980s. The aircraft were converted from second-hand maritime patrol variants of the Orion. The first example had started life as a P-3B for the Royal Australian Air Force (RAAF). Ex-U.S. Navy P-3s were also converted.

The initial three P-3 AEWs were equipped with the AN/APS-138 radar. The same radar was used on early E-2C Hawkeye airborne early warning and control aircraft operated by the U.S. Navy, as well as several other armed forces internationally.
“The Customs Service had previously borrowed U.S. Navy E-2Cs to meet its antinarcotics surveillance requirements, but required an aircraft with longer range and on-station time,” according to a 2006 report from Forecast International. “In June 1989, the U.S. General Accounting Office issued a report on the drug interdiction P-3B AEW aircraft. The findings indicated that the radar performance was as specified, but the P-3B (when compared to the E-2C) was less costly to operate per square mile of area covered because of the higher cruising speed and longer endurance. The P-3B had at least twice the in-flight endurance of the E-2C.”
Starting in the 1990s, USCS began the process of acquiring additional P-3 AEWs with newer AN/APS-145 radars, as also used on later model E-2Cs. The original AEW Orions were eventually refitted with APS-145s, as well. It’s worth noting here that the U.S. Coast Guard separately moved to acquire an AEW version of the C-130H, designated the EC-130V, in the 1990s, which used the AN/APS-125 radar, also used on older E-2s. Budget cuts led to the end of that program. The EC-130V that had been built was redesignated as an NC-130H and subsequently used for test purposes.

The P-3 AEWs were also equipped with a sensor turret containing electro-optical and infrared (EO/IR) video cameras, allowing the aircraft to more closely investigate targets spotted on radar. CBP regularly conducted P-3 operations that paired AEWs with LRT variants to provide an even broader array of sensor capabilities on missions. The LRTs have EO/IR sensor turrets, as well as AN/APG-66 and SeaVue radars. The pulse-doppler AN/APG-66 is primarily designed for spotting and tracking aerial targets, and was originally used on early variants of the F-16 fighter. SeaVue is a multi-function type with surface search and synthetic aperture radar (SAR) imagery modes. Images produced via SAR are highly detailed maps of the surface below, and can be captured day or night, and regardless of any cloud cover, smoke, or dust.
Beyond radars and other sensors, the P-3 AEWs also had a robust communications suite consisting of VHF and UHF radios, as well as satellite communications links by the end of their career. CBP’s entire P-3 fleet, including the AEWs and LRTs, has received various updates over the years, including new ‘glass cockpits’ starting in the early 2000s.
Though primarily employed in support of counter-narcotics interdiction operations, the airborne radar and command and control capabilities were also applied to other missions, including disaster relief and humanitarian assistance efforts at home and abroad. As an example, CBP’s P-3 AEWs helped with air traffic coordination, as well as provided other support, during relief efforts in Texas in the wake of Hurricane Harvey in 2017.
At the same time, CBP’s entire P-3 fleet, including both the AEW and LRT versions, has only been getting increasingly older and difficult to sustain. The P-3B variant first entered U.S. Navy service in the 1960s. CBP did put its P-3s through a Service Life Extension Program overhaul in the 2010s, which included “new wings and tail for each aircraft and completely strips down the aircraft to its bare metal for an inspection,” according to a 2014 press release.

A key question now is how CBP will fill any gaps left by the retirement of the final AEW version. The agency does continue to operate a mix of other crewed fixed-wing aircraft with mixtures of radars and other sensors, as well as MQ-9 drones, but none of these platforms are equipped with a sensor like the AN/APS-145. CBP also has a network of tethered aerostats with radars at fixed sites around the Caribbean. As an aside, General Atomics, together with Saab, is now working on an AEW configuration for the MQ-9B drone, but there are no known U.S. orders for that capability at the time of writing. That platform will not offer the same level of flexibility and look-down capability as modern crewed AEW aircraft, either. Look-down AEW capability is only growing in importance today amid expanding and evolving drone threats, including to the U.S. homeland.
Another look at one of CBP’s now-retired P-3 AEWs. CBP
The Air Force, in particular, is also aiming to eventually push most, if not all, air moving-target indicator (AMTI) tasks currently performed by aircraft like the E-3 and E-7 into space. The service is heavily investing to accelerate the fielding of those capabilities, which could eventually offer revolutionary constant, persistent coverage globally. The first of those satellites are still not expected to reach an early operational state until 2028. It is possible that CBP could get access to a tailored data feed from this system when it does become operational. It still does not obviate the need to have crewed or uncrewed aircraft capable of more closely investigating tracks of interest using EO/IR cameras and other sensors.
Whatever the future might now hold, CBP’s unique time as the operator of the P-3 AEW aircraft has come to an end.

The volume of munitions expended in the course of U.S. operations against Iran this year has been and continues to be a hot topic of discussion, and there has been relatively little official data provided on this front. However, now we know that the F/A-18F Super Hornets of the U.S. Navy’s Strike Fighter Squadron 41 (VFA-41), the “Black Aces,” launched 421 missiles and bombs during their time supporting Operation Epic Fury.
This new insight into VFA-41’s role in the conflict with Iran comes from a photo of a large board listing the squadron’s weapons expenditures during Epic Fury, via Jeff Rojas, who goes by the handle @jro_photography on Instagram. Rojas also shared pictures recently taken of VFA-41’s Super Hornets. The Black Aces were one of the squadrons assigned to the Nimitz class aircraft carrier USS Abraham Lincoln, which has been on a marathon deploymentsince last year. The carrier only left the Middle East region last month and is now set to formally return home to San Diego, California, within days. Per the Pentagon’s official timeline, Operation Epic Fury began on February 28 and concluded on May 5, though U.S. forces have continued to conduct strikes on Iran, on and off, since then.

The complete tally of munitions employed as shown on the board, broken down by type, from greatest to fewest, is as follows:
1 GBU-12/B 500-pound-class Paveway II laser-guided precision-guided bomb
The total cost of all of these munitions, using available data from U.S. military budget documents, is very roughly $43,646,000, at least. Unit costs fluctuate regularly due to a variety of factors. Furthermore, the exact price tag for different JDAMs can be somewhat difficult to calculate given how the individual components are budgeted.
The JDAM is really a family of kits that turn standard unguided ‘iron bombs,’ which can vary significantly in the kinds of effects they are designed to produce, into warheads for precision-guided munitions. This is exemplified by the (V)2 and (V)4 subvariants of the GBU-31/B mentioned here, which are built using standard high-explosive and bunker-buster bombs, respectively. No specific subvariants of the GBU-32, GBU-38, or GBU-54 were mentioned in the information provided. Standard JDAMs can also only be employed against static target coordinates. The LJDAM kits add a laser guidance component (akin to what is found on Paveway-series bombs) that enables strikes against moving targets.

No specific version of AGM-154 is mentioned, either, but the C and C-1 types, which have multi-stage bunker-busting warheads, are the only ones understood to be in service today. Remaining A variants, which were loaded with 145 small bomblets, were removed from U.S. service in 2008 as a result of new guidelines on cluster munitions issued under President George W. Bush. A planned AGM-154B, which would have contained six “smart” Sensor Fuzed Munition bomblets, was never produced. You can read more about the full JSOW family here.
We do not know exactly what targets any of these munitions were employed against. However, a picture that Jeff Rojas grabbed of one of VFA-41’s Super Hornets, seen toward the top of this story and in part below, shows a very interesting broken submarine kill marking, with the added text “Sub Buster.” The jet also has a number of more typical bomb-shaped kill marks.

It is extremely likely that the AIM-9Xs and AIM-120s were fired at Iranian drones, though they could have been launched at incoming cruise missiles, as well. At the time of writing, there are no known or reported instances of U.S. military jets engaging crewed Iranian aircraft in the course of the conflict to date. In 2024, the Navy carried out a crash program that increased the total number of AIM-9Xs that F/A-18E/Fs could carry per sortie, specifically in response to Houthi drone threats. Super Hornets loaded with nine air-to-air missiles are now referred to as “Murder Hornets.”
It is also important to remember that this is a discussion of the munitions expended by just one Navy strike fighter squadron. Lincoln‘s air wing includes four strike squadrons, three with Super Hornets and one with F-35Cs, as well as units flying other types of aircraft and helicopters. The carrier was just one part of a much larger array of air, naval, and ground forces that participated in Operation Epic Fury and subsequent operations against Iran. For additional context, consider that the entire Eisenhower Carrier Strike Group, including its entire air wing and escorting ships, fired off 770 munitions in total, by the official count, during very active combat operations in and around the Red Sea between November 2023 and June 2024.

As such, the tally of munitions launched from VFA-41 Super Hornets offers a very interesting view into that squadron’s contributions to Operation Epic Fury, as well as the full scale and scope of the conflict with Iran.
Special thanks again to Jeff Rojas for sharing the details about VFA-41’s participation in Operation Epic Fury and his pictures with us.
Seven companies are said to now be in the running to develop a lower-cost and highly modular drone to succeed the MQ-9A Reaper. Though the field has some well-established entrants and some far lesser known names, the inclusion of Otto Aerospace in this group is particularly unexpected and interesting to examine. Otto has made bold, but still unrealized pronouncements about disrupting the aviation industry with potentially revolutionary high-efficiency designs that could have civilian and military applications. TWZ has been steadily tracking the company’s developments since we first reported on the existence of the Celera 500L aircraft back in 2017.
Air & Space Forces Magazinefirst reported on Wednesday that Otto Aerospace (previously Otto Aviation), as well as Anduril, Chaos Industries, General Atomics Aeronautical Systems, Grid Aero, Shield AI, and Swarm Aero, had “made the cut” for the Massed Modular Aircraft (MMA) program, citing anonymous sources. The MMA effort formally kicked off in July, and the Air Force is now aiming to have a fleet of at least 500 of these drones by 2032.

An industry source has also told us that these seven companies are moving ahead in the MMA program. The Air Force has not yet offered an official confirmation.
“The Air Force’s partnership with the Defense Innovation Unit is accelerating requirements development and rapid prototyping by leveraging commercial innovation and reducing timelines,” a spokesperson for the service said when we asked for more information. “We continue working with industry to inform requirements and assess potential solutions as we shape the future MMA capability.”
TWZ has also reached out to all of the companies on the list for more details.
As mentioned, it is unexpected and especially interesting to see Otto named here in the context of MMA. The company’s core design philosophy centers around what is called laminar flow. Broadly speaking, this refers to liquid or gaseous “fluids,” including air, flowing in smooth, regular layers across a surface with little to no mixing between them. In aviation, optimization for laminar flow translates to reduced drag and improved aerodynamic efficiency. This, in turn, can offer a host of benefits, including when it comes to fuel economy, extended range, and overall performance, as well as reductions in operating costs.
With this in mind, all of the designs that Otto has shown to date, starting with the Celera 500L, have been based around teardrop-shaped fuselages to maximize laminar flow benefits. Many of them also feature long, slender glider-like wings. The sudden and unannounced appearance of the very exotic and futuristic-looking Celera 500L at the Southern California Logistics Airport in 2017, at which time nothing was known about the aircraft or its manufacturer, caused a stir in the broader aviation community. TWZ was the first to report on the plane and then unmasked its identity.
On top of the laminar flow-optimized shaping, the Celera 500L was a pusher-propeller design powered by a single high-efficiency, turbocharged, multi-fuel V12 piston engine. A relevant patent held by Otto also describes a novel exhaust system with a heat exchanger that provides an additional boost in thrust.
Otto conducted an extensive test campaign with the Celera 500L, taking the aircraft up to an altitude of 15,000 feet and to a speed of 250 miles per hour. The company posited that this would translate to a cruising speed of around 460 miles per hour at the design’s intended operating ceiling of 50,000 feet.

Development focus at the company has since shifted to the jet-powered Phantom 3500, which has a much revised design compared to the Celera 500L. Otto has said previously that it expects this aircraft to burn just 115 gallons of fuel per hour, further underscoring the benefits of its laminar-flow-centric approach. Comparably sized business jets like the Bombardier Challenger 350, Cessna Citation Latitude, and Embraer Praetor 500 consume around 300 gallons per hour, according to the company, citing data from Jet Support Services, Inc. (JSSI).

It is also worth noting here that Otto has already developed a drone with a “highly laminar-flow efficient airframe” for the U.S. Defense Advanced Research Projects Agency (DARPA). The company announced the successful completion of a flight test campaign in May. The pusher-propeller design has a teardrop-shaped main body, a glider-type main wing, and a T-tail at the end of a boom that extends to the rear of the aircraft. DARPA plans to use that drone to demonstrate laser-based power beaming technology that could be used to relay electricity to forward operating locations. The technology could also dramatically extend the endurance of an electrically-powered drone, potentially allowing it to stay in the air indefinitely.
The drone for DARPA is far too small to meet the Air Force’s MMA requirements. However, “the program leveraged Otto’s aerodynamic expertise to design and flight-test an unmanned vehicle that could inform design parameters for future energy-relay systems or more extremely fuel-efficient, long-endurance platforms,” per a press release Otto put out in May.
Otto Aerospace developed this drone, seen here rigged up for launch from a pickup truck, for the US Defense Advanced Research Projects Agency (DARPA). Otto Aerospace
TWZ has highlighted in the past how the general range, fuel economy, and other advantages inherent to Otto’s designs could be even more pronounced in a configuration that does not need to support a human crew. Furthermore, Otto has previously shown militarized concepts, crewed and uncrewed. As we’ve written in our earlier coverage of the Celera 500L:
“Though primarily aimed at civilian and commercial operators, Otto’s new website also highlights the potential for the Celera 500L to use its long-range and high fuel economy to support military missions, including transporting personnel and cargo, as well as conducting intelligence, surveillance, and reconnaissance (ISR) missions. A version of the aircraft, possibly unmanned, equipped with any number of sensor suites could be an impressive persistent surveillance and communications relay platform able to orbit over particular areas for very long periods of time and cover a wide swath of the battlefield from its high perch. It could also be able to reposition itself quickly and transit to its tasking area at jet-like speeds.”

While we have yet to see an explicit MMA proposal from Otto, a laminar flow-optimized drone could be a very attractive offering, given the program’s focus on reducing costs while having an unrefueled combat radius of at least 2,300 nautical miles, among other capabilities. A more efficient design could further translate to a drone that needs less fuel to meet range and other requirements, which, in turn, could allow for a smaller and/or cheaper design overall. Weight and physical space savings afforded by reduced fuel demand could be used to increase ordnance and other payload capacity, too. You can read more about what is known about the MMA requirements here.
There are more companies beyond Otto in the running. With the Air Force aiming to buy hundreds of MMA drones in the coming years, there will be stiff competition.
General Atomics, which developed and produced the MQ-9A, has publicly put forward its own proposal for a successor, called Wildfire. The new drone draws heavily on experience with the Reaper, as well as other drones in the company’s portfolio, and you can read more about what is known about that design here. General Atomics declined to offer additional comment in response to questions regarding the current state of the MMA program. As an aside, General Atomics is also now on contract to build higher-end FQ-42 Vengeance drones for the Air Force, one of two designs intended for higher-end air combat the service is acquiring under its Collaborative Combat Aircraft (CCA) program.

The other company building CCA drones for the Air Force is Anduril, with its FQ-44 Fury, and it has now also been named in relation to the MMA effort. Anduril has unveiled two other very different tactical drones since 2025, the twin-engine hybrid-electric tail-sitting Omen, designed primarily for surveillance and reconnaissance, and Thunder, an armed tiltrotor pitched as an uncrewed companion for crewed rotorcraft. Neither of those uncrewed aircraft would seem to directly align with the stated MMA requirements, but might serve as a starting place. Anduril also has a history now of developing new uncrewed platforms and other systems discreetly, and sharing them with the public only when they have become relatively mature.

What design Shield AI might be offering is unknown. The MMA requirements would seem to sit between the company’s V-BAT drone, which is in service with several armed forces today, including in the United States and Ukraine, and the much higher-end X-BAT that is now in development. Shield AI has been working to expand on the V-BAT design, including plans to integrate air-launched munitions. Both V-BAT and X-BAT are also vertical-takeoff and landing designs. Beyond drones, Shield AI remains a major developer of artificial intelligence-driven autonomy packages for the U.S. military and others.
Earlier this month, newcomer Swarm Aero unveiled a new drone with performance and capabilities that align with the stated MMA requirements earlier this month. Called Gamera, the design has a single propeller at the front of a small central fuselage, together with sponsons holding large fuel cells on either side and a twin-boom tail configuration broadly reminiscent of the OV-10 Bronco light attack aircraft, as TWZ previously reported on in more detail.
Grid Aero is publicly developing a twin-engine cargo drone called the Lifter Lite, in part with funding from AFWERX, the Air Force’s internal technology incubator. Whether the company might work to adapt the Lifter Lite, which has been undergoing testing at least on the ground, to meet the MMA requirements or has proposed something entirely different is not known.

The last firm on the list, Chaos Industries, does not appear to show any drone designs on its website at the time of writing. It is primarily known as a developer of radar systems, especially for use in counter-drone systems. The company declined to comment in response to TWZ queries regarding the MMA program.
To reiterate, the Air Force still has not confirmed the full list of MMA program contenders. Otto’s participation would be a standout, but the field as it is understood now features a number of very established drone makers, as well as emerging start-ups, all vying for a very lucrative opportunity. On top of the potential just to supply hundreds of drones upfront, those uncrewed aircraft look set to be a key part of the Air Force’s force structure for years to come, and will need to be supported throughout their lifecycles. The MMA requirements put heavy emphasis on modularity and open-architecture systems to allow for the rapid integration of new and improved capabilities and functionality down the line.
The Air Force has also previously raised the possibility of selecting multiple vendors to produce designs under the MMA program, or to pursue follow-on rounds of competition to help meet its operations requirements. This is exactly how the service has been running the CCA program, and has already led to the aforementioned production contracts with General Atomics and Anduril. In addition, the Air Force is targeting a base $10 million unit cost for each MMA drone, a price point that would help make losses more tolerable, and could open the door to acquiring a fleet of far more than 500 examples.
It is also important to remember that the Air Force has tried and failed on several occasions to develop and field an MQ-9A replacement. As TWZ has previously explored in great detail, the service’s view of what that drone should be has also evolved over time, with the current MMA program squarely focused on a more affordable option that does not put a heavy premium on survivability. The Air Force has acknowledged potential budget and other hurdles to its new effort. At the same time, heavy continued operational demand for Reapers, coupled with dozens of losses in the course of the war with Iran, as well as other operations in and around the Middle East in recent years, have put major new emphasis on finally finding a successor.
Overall, beyond what is already known about potential MMA offerings, it will be very interesting to see what Otto and the other contenders put forward to finally succeed the iconic Reaper.

The U.S. government set off conventional explosives inside a tunnel deep in the Nevada desert this week in a test designed to replicate a so-called “decoupled” nuclear detonation. Data collected is now being used to help improve methods for detecting this kind of nuclear testing. Just earlier this year, American authorities accused China of using decoupling to conceal new nuclear tests despite the country’s stated moratorium on such activities.
The test, which involved the use of chemical high-explosives and radiotracers, was conducted yesterday inside P Tunnel in Area 12 of the Nevada National Security Site (NNSA), according to a press release from the National Nuclear Security Administration (NNSA). The NNSS, which is situated within the boundaries of the U.S. Air Force’s Nevada Test and Training Range (NTTR), is used for a wide variety of testing purposes today. An agency under the Department of Energy, NNSA’s main jobs are to oversee the development and production of nuclear weapons, as well as manage America’s nuclear deterrent stockpile.

“This experiment is especially focused on further enhancing the U.S. capabilities to detect a ‘decoupled’ explosion,” per NNSA’s release. “Data collected from the experiment will be used to validate scientific models and refine algorithms that are critical to U.S. nuclear explosion detection efforts.”
“Just as a stealth aircraft looks smaller on radar, decoupling can greatly muffle the signals detected by nuclear detection sensors, making a large explosion appear smaller,” the release explains. “In a conventional, or ‘coupled,’ underground nuclear test, a device is placed deep in a hole in close contact with the rock, allowing much of the explosion’s shockwave to reach sensors. In a decoupled test, by contrast, the device is detonated inside a large underground chamber, substantially reducing the explosion’s seismic signature.”
“In this experiment, researchers gathered measurements using a broad suite of advanced sensors, including accelerometers, seismometers, infrasound sensors, electromagnetic sensors, chemical and radiotracer samplers, and meteorological sensors,” it adds. ”Together, these measurements will improve scientists’ understanding of the signatures produced by underground explosions and strengthen the United States’ ability to detect and characterize nuclear explosive events.”
The U.S. already maintains a U.S. Atomic Energy Detection Systems (USAEDS) network, which is overseen by the U.S. Air Force Technical Applications Center (AFTAC). USAEDS is made up of more than 3,600 sensors positioned around the world. USAEDS is also tied in with the International Monitoring System (IMS), which is managed by the organization responsible for overseeing the Comprehensive Nuclear-Test-Ban Treaty (CTBT). AFTAC also supports the mission to monitor for potential nuclear testing globally using a fleet of specially configured WC-135R Constant Phoenix aircraft. In addition, those planes are used to help keep watch for unusual spikes in atmospheric radiation that could point to nuclear or radiological accidents or other incidents leading to the spread of potentially dangerous radioactive material.
With regard to the USAEDS network specifically, “once a disturbance is detected underground, underwater, in the atmosphere or in space, the event is analyzed for nuclear identification, and the findings are reported to command authorities,” according to AFTAC’s website.
As mentioned, the U.S. government has accused its Chinese counterparts of using decoupling to conceal new nuclear testing, and NNSA’s press release draws explicit attention to these allegations. At the annual Conference on Disarmament in Geneva, Switzerland, in February, Thomas DiNanno, Under Secretary of State for Arms Control and International Security, said that China had conducted at least one such test at Lop Nur on June 22, 2020. The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) subsequently said the IMS had not detected an event matching that description at that location on that date. For its part, the Chinese government has denied the accusation.
The social media posts below include satellite imagery showing activity at Lop Nur that could point to new nuclear testing activities in recent years.

While China is a signatory to the CTBT, the country has never ratified it. The Chinese government last acknowledged a critical-level nuclear test in 1996, after which a self-imposed moratorium was put in place, at least publicly. As an aside, the United States has also signed, but never ratified, the CTBT, and has a similar self-imposed moratorium on nuclear testing since 1992. It is worth noting that the treaty does not ban so-called sub-critical testing, which involves fissile material, but does not result in a full-fledged nuclear reaction.
Last week, The Wall Street Journal reported that the Trump administration has been holding new talks with the Chinese government regarding various aspects of the country’s massively and rapidly expanding nuclear arsenal, including the testing allegations. That story immediately preceded a state visit by China’s President Xi Jinping to Washington, D.C., to meet with Trump.

“The discussions between American and Chinese officials have centered on measures to reduce nuclear risks and haven’t been aimed at negotiating a formal arms-control pact, an effort Beijing has sharply rebuffed in the past,” according to that report. “The Trump administration has begun to highlight the possibility of implementing new verification measures.”
“Independent experts say seismic instruments might be placed on or near test sites,” The Journal‘s story also noted. “Another possibility, which was floated during the Biden administration, is to install radiation-detection equipment at test sites.”
NNSA’s announcement about the test at the Nevada National Security Site is certainly an example of the development underway already of new means of verification that could be deployed at sites around the world.
The Russian government has said it is ready to conduct new nuclear tests if the United States pursues this course of action. The last official nuclear test in Russia came in 1990 right before the fall of the Soviet Union.
“It takes nuclear expertise to detect nuclear activities and experiments like these [to] ensure America remains unmatched in detection,” NNSA Administrator Brandon Williams said in a statement yesterday in light of the test in Nevada. “The Trump Administration has made it clear that the United States will lead from a position of strength. You cannot evade American innovation. With this experiment, we are sending a clear message: under this administration, America will never be outmatched.”
The Pentagon has announced plans for a new functional combatant command, very broadly akin to U.S. Special Operations Command (SOCOM) or U.S. Space Command (SPACECOM), but for operational activities involving autonomous and robotic capabilities. Secretary Pete Hegseth has also announced new initiatives to help further accelerate the fielding of uncrewed systems in the air, at sea, and on land, as well as to explore future warfighting challenges. All of this builds on previous and long-overdue efforts to prioritize the fielding of various tiers of drones, as well as artificial intelligence (AI) and other emerging technologies, across domains, but there are questions about how these new efforts will translate into tangible developments.
Secretary Hegseth unveiled plans for what is tentatively dubbed Autonomous Warfare Command (AUTOWARCOM), as well as the aforementioned initiatives, called Project Agincourt and Project Meridian, during a speech to service members today at the U.S. Marine Corps’ base in Quantico, Virginia. Hegseth called this a State of the Force address, and said he planned to make it an annual event.

“At my direction, we are announcing the creation of Autonomous Warfare Command, or AUTOWARCOM, a new four-star combatant command with service-like authorities built to scale autonomous and robotic capabilities across the joint force in the fastest peacetime shift in modern military history,” Hegseth declared. “Drone warfare supercharged by SI-enabled targeting is the biggest battlefield revolution in generations. You already know that. Yet when I was sworn in to the Department of Defense, there was scant urgency in this domain.”
Hegseth called attention to the Drone Dominance initiative he unveiled last year, as well as the establishment of Joint Interagency Task Force 401 (JIATF-401), as examples of steps the Department has already taken in this regard. JIATF-401 is notably focused on counter-drone capabilities, as you read more about here.
“It’s a good start, but it’s certainly not enough. The pace of war is changing faster than the process to support it. Cheap compute, super intelligence, and advanced commercial manufacturing have enabled the proliferation of low-cost, high-precision strikes,” Hegseth continued. “For 40 years, the United States relied … primarily on expensive weapons that placed quality over quantity. Now, that approach gave us a lot of enormous advantages, and we need to preserve those capabilities. But today we need both quality and quantity. The term you know is high-low mix. An analogy is a thunderstorm. We need bolts of lightning high, our existing high-end kill chains capable of striking unexpectedly and decisively. We also need steady wind and rain, mass drones and other autonomous attritable systems that flip the cost exchange and impose unrelenting pressure on an adversary on the battlefield.”
Hegseth highlighted lessons learned from the ongoing conflict in Ukraine as underscoring these points.
.@SECWAR "Ukraine’s lesson is not that one type of drone wins wars but rather the need for a purpose-built system that maximizes the ability to adapt.

“So today, with Autonomous War Command, AUTOWARCOM, we institutionalize and we supercharge the era of SI, robotics, and autonomous systems, all in order to win,” he added.
A memo the Pentagon has now released makes clear that the establishment of this command is contingent on Congressional approval, and the current goal is for it to be established by October 1, 2027.
“Autonomous Warfare Command will define joint needs and integrate Service-provided forces in support of geographic combatant commanders,” the memo also notes. “It will test equipment and force designs with realistic opposition in demanding exercises and rugged environments, modify rapidly, and field what works. We must build a wartime arsenal whose main product is adaptation at the edge.”
Many questions remain to be answered about how these activities will work with what’s already being done within the individual services, and how all of that will translate into operational activities. Part of Project Agincourt’s role will be working to help answer the questions above. The name here is a reference to the battle in 1415 in which British forces prevailed over their French opponents, famously in part through the application of a particular military technology, the longbow.
The two main tasks outlined in a memo today on Project Agincourt, one of which is laying the groundwork for AUTOWARCOM. US Military
The office of the Direct Reporting Portfolio Manager for Unmanned Systems (DRPM-UxS) will lead this initiative. Owen West, head of the Pentagon’s Defense Innovation Unit (DIU), and U.S. Navy SEAL Senior Chief Max Strasiser are set to serve as the Chief Executive Officer and Chief Operating Officer of the DRPM-UxS, respectively.
Project Agincourt will also “prototype a new construct called warfighting acquisition, not just acquisition that happens at the Pentagon,” according to Hegseth. “This model fuses operators with entrepreneurs in rapid adaptation cycles while distributing decisions and dollars closer to frontline units, to combatant commands. Realistic training exercises, and when possible, the crucible of combat, will be used to compress innovation timelines and scale what works.”
“Also today, we are phasing in new MOS [Military Occupational Specialty] frameworks within each military department to support our shift to autonomy,” the Secretary also noted during his speech in the context of Project Agincourt and the plan for AUTOWARCOM. “We need institutional knowledge and career paths for a new generation of autonomous warfighters.”
Project Meridian sits adjacent to these efforts and has a broader mandate to explore ways to ensure the U.S. military maintains its technological edge on future battlefields.
“Project Meridian, the future of warfare, is not about developing new strategies or new policies. We already do that. Rather, its purpose is to creatively look to the future, and identify the domains that we must conquer, and capabilities we must master,” Hegseth said. “We need to be looking forward into the future to achieve technological and military dominance on the battlefield for decades to come. It is futuristic on purpose. Their work will be focused on discovering, developing, and fielding the weapons and systems that our children and our grandchildren will need in their lifetimes, without any creative limitations or restrictions, on any future battlefield, from under the Earth to beyond the Moon.”
.@SECWAR “Today, at my direction—I am announcing Project Meridian, an effort led by America’s best minds to study the future of warfare.
“Project Meridian will study the battlefields of the future, identify which weapons and technologies warfighters will need to harness to dominate in these environments, and propose actionable solutions to start developing, testing and fielding these capabilities such that America will have overmatch for the 21st century and beyond,” according to a separate memo the Pentagon put out today. “The Joint Staff and all services should be prepared to connect their future warfare efforts and research to Project Meridian.”
The full text of the Project Meridian memo put out today. US Military
Furthermore, “Project Meridian will leverage critical perspectives from outside the Pentagon, drawing upon a group of top technologists, innovators, business leaders, policy makers, and national security experts,” according to the memo. “Project Meridian’s primary function will be to map the trajectory of future warfare, identify critical capability gaps, and propose actionable solutions in furtherance of the identified goals in the 2026 National Security Science and Technology Strategy.”
This is also very much a near-term initiative, with Hegseth demanding a final report no later than 120 days from now, or January 28, 2027. The Pentagon’s Chief Technology Officer, Emil Michael, has been directed to set up this project. Today, Hegseth also named Elon Musk, Palmer Luckey, and Newt Gingrich as key members.
Elon Musk, founder of SpaceX, which dominates the commercial space launch and services market globally, as well as the host of other companies, has had an on-again-off-again relationship with the Trump Administration. Palmer Luckey is another entrepreneur now best known for founding Anduril, which has increasingly been a major player in the U.S. defense industry. Newt Gingrich, a highly influential member of Trump’s Republican Party and former Speaker of the U.S. House of Representatives, has more recently become an outspoken advocate of advancing AI technology in the United States.

The inclusion of Musk and Luckey does raise ethical questions, as they both lead companies with major U.S. government contracts already, and which could be in line to see more opportunities based on Project Meridian’s findings. What guardrails might be put in place to prevent conflicts of interest is unclear.
To reiterate, it remains to be seen how all of these efforts will progress and how, or if, they will ultimately translate to more tangible developments. The U.S. military has a long history now of launching high-profile initiatives that still struggle to demonstrate real progress, despite widespread support for accelerating the fielding of uncrewed systems, AI, and other advanced technologies. The Pentagon has certainly produced tangible results through other organizational shifts in recent years, including the aforementioned Drone Dominance initiative and JIATF-401, as well as the Replicator initiative under President Joe Biden.
At the same time, there are real potential hurdles to these new plans. The Pentagon has itself already acknowledged that support from Congress will be key to the AUTOWARCOM vision. Annual budgeting, and the uncertainty that often surrounds that will also be a factor. There is also the matter of efforts to expand the U.S. defense industrial base. The limitations of existing U.S. industrial capacity and supply chains have already become a matter of national debate in light of concerns about dwindling stockpiles of critical munitions as a result of the ongoing conflict with Iran, as well as a succession of other global crises in recent years.
During his speech, Hegseth called attention to efforts to broaden the defense industrial base with new, smaller firms, as well as agreements with large established contractors to expand on their existing capacity. He also highlighted the Trump administration’s $1.5 trillion defense spending plan for Fiscal Year 2027 and issued a new call on Congress to pass an additional $350 billion reconciliation package.
With today’s announcements, the Pentagon has certainly reinforced its commitment to expanding the fielding of uncrewed and other high-tech capabilities across all branches of the U.S. military, but there is clearly work still to be done to turn those visions into realities.
The U.S. Air Force is looking at adding a missile warning system (MWS) to its new F-15EX Eagle II fighters. This will give the aircraft a way to optically detect incoming missile threats, especially passively guided ones like heat-seeking infrared-guided missiles, which they currently lack. The continued absence of an MWS has become more pronounced in light of recent combat experiences over Iran.
The F-15EX is derived from earlier F-15 variants that all have MWSs, and it had seemed logical to expect the Eagle II would feature this capability. So it was puzzling when the first examples rolled out without such a system, and no apparent plans to install one on a jet already costing upwards of $100 million. The omission has been glaring for years now, especially given that the aircraft has all the provisions for such a system, including blanked-over spots for the sensors.

Now, the Air Force Life Cycle Management Center’s (AFLCMC) Fighters & Advanced Aircraft Directorate “is seeking sources for the procurement of an operationally qualified threat missile launch and approach warning system for rapid integration into the United States Air Force (USAF) F-15EX Eagle II fighter aircraft,” per a contracting notice put out yesterday. “The MWS must alert the F-15EX aircrew to the presence of missiles that may threaten the aircraft without unreasonably distracting the aircrew with false alarms.”
As mentioned, the F-15EX is already configured to accommodate an MWS, inside and out, something AFLCMC’s notice emphasizes. This is a result of the Eagle II having been directly derived from the F-15QA variant for Qatar, which itself was an outgrowth of the F-15SA for Saudi Arabia. While many of the F-15EX’s advances come from these aircraft, the first F-15 variant to get an MWS was actually Singapore’s F-15SG. The Advanced Eagle line and the F-15SG are part of Boeing’s extended F-15E Strike Eagle family.

“The MWS must use the six (6) pre-existing F-15EX sensor locations, data cables, power cables, and cooling,” the contracting notice says. “It must be easily, safely, rapidly, and organically installable and removable in the field by USAF military aircraft maintenance personnel without requiring any change to aircraft configuration beyond installation of MWS line replaceable units (LRUs) in the six (6) pre-existing locations in the aircraft dedicated for missile warning.”
The most visually prominent of those pre-existing sensor locations are two horn-like sponsons, one on each side of the forward fuselage right below the cockpit canopy. There are two more locations at the ends of the jet’s tail booms. The last two locations are situated so additional sensors can face straight up and down to provide total 360-degree coverage.

The sources sought notice does not mention any specific MWS and invites prospective vendors to submit proposals. It also stresses that the Air Force is still in the “market research” phase of the contracting process and that it “does not constitute [a] solicitation and shall not be construed as a commitment” to buy such a system.
The F-15SA uses the AN/AAR-57 Common Missile Warning System (CMWS), and this system is understood to also be found on the F-15QA. Beyond F-15 variants, versions of the AN/AAR-57, for which BAE Systems is currently the prime contractor, are fielded today on a wide variety of other fixed-wing aircraft and helicopters, including various types in U.S. military service. CMWS variants are notably found across the U.S. Army’s AH-64, UH-60, and CH-47 helicopter fleets.

All versions of the CMWS consist of several electro-optic missile sensors (EOMS), the number of which varies from platform to platform, linked to a central electronic control unit (ECU). The system is also designed to be integrated into larger defensive suites.

While the AN/AAR-57 is a proven system with years of successful integration on the F-15 and other platforms, it is just one option of the open market today. The Air Force could choose to take another route, possibly with a new system that offers added functionality.
The addition of any MWS will give the F-15EX a valuable, if not increasingly critical, boost in defensive capability. The Eagle II does already have an extremely powerful self-protection suite, including the Eagle Passive/Active Warning Survivability System (EPAWSS). However, it is heavily geared toward defending against radar-based threats that pump out signals that can be detected and jammed. Infrared-homing anti-air missiles zero in on their targets passively.
In general, MWSs also typically make use of passive infrared sensors to spot the heat plumes of missile launches and the thermal signatures of those threats as they continue their approach. BAE Systems says current-generation versions of the AN/AAR-57 are sensitive enough to detect infantry anti-armor rockets being launched, as well as small arms fire from the ground, under the right circumstances. Though an MWS is not an active countermeasure unto itself, the early warning it provides gives critical time to deploy flares or employ other defensive capabilities, or just take evasive action.
TWZ touched on all of this last month after The New York Times reported new details about the shootdown of an F-15E Strike Eagle over Iran in April. A shoulder-fired, heat-seeking surface-to-air missile, also known as a man-portable air defense system (MANPADS), is said to have been responsible, though this remains unconfirmed. The Strike Eagle also lacks an MWS. The Times‘ story said that the F-15E’s defensive suite provided the crew with only half a second of warning. As we noted at the time, it would actually have provided no warning given that the Strike Eagle also lacks an MWS.

Even before the current conflict with Iran broke out, TWZ had questioned the F-15EX’s lack of this capability given the general focus on increased survivability to match expanding threat ecosystems globally. EPAWSS is already a reflection of that reality, and could be made even more capable when tied together with an MWS. In May, we had reached out to the Air Force about any plans to integrate an MWS onto the F-15EX in light of observations from the ongoing conflict with Iran. The service told us then that it had no details to share. Whether the service now has any plans to add MWSs to the Strike Eagle fleet, which would require more significant integration work, is also unknown.
Buying F-15EX and not springing for the missile approach warning system is absolutely the dumbest thing. $100M fighter, but let's save a few bucks on a key defensive advantage. You are not always going to get a radar spike from a threat, even at altitude.
Infrared homing anti-air missiles, as well as air defense systems that use passive infrared sensors for target detection and cueing, are certainly not threats limited to Iran. In Yemen, Iranian-backed Houthi militants have been making good use of these capabilities for years now, something else we have explored in great detail in the past. The Houthis claimed to have downed a Saudi Arabian F-15 just earlier this month and, per a now-long standing modus operandi, subsequently released video captured through a ground-based forward-looking infrared (FLIR) system as evidence. The group also shared images of the wreckage of what looked to be an F-15SA Advanced Eagle, underscoring the dangers posed even to aircraft equipped MWSs.

These threats are not limited to the Middle East more broadly, either, and are only increasingly likely to be encountered in future conflicts globally. The emergence of ever-more capable and longer-range anti-air missiles with infrared or dual-mode guidance systems is a significant factor in all this. Expanding use of passive infrared search and track (IRST) systems on aircraft and infrared sensors on ground-based air defense systems are part of this larger equation, as well.
How the Air Force ultimately decided to proceed with the integration of an MWS onto the F-15EX fleet remains to be seen. However, the Eagle II’s lack of this capability is only becoming more striking, especially in light of the conflict with Iran.
