B-52 To Get Stealthy AGM-158C Long-Range Anti-Ship Missiles

The U.S. Navy is preparing to sign a contract with Lockheed Martin to integrate the stealthy AGM-158C Long Range Anti-Ship Missile (LRASM) onto the Air Force’s B-52 Stratofortress bombers, according to an October 7 government notice. The effort would add another long-range maritime strike option to the U.S. bomber force as the military looks to counter increasingly capable adversary naval forces, especially in the Indo-Pacific theater.

The planned contract comes months after the Air Force revealed that the stealthy B-2 bomber can also launch LRASM, a capability that had not previously been publicly disclosed. You can read more about that here.

The latest Naval Air Systems Command (NAVAIR) notice says the command intends to enter into sole-source negotiations with Lockheed Martin and subsequently award a cost-plus-fixed-fee delivery order covering LRASM integration on the B-52. The work would include missile software updates, associated testing, repairs to test assets, and failure review boards.

The notice does not provide a schedule for completing the integration or fielding the capability.

The B-52 is already capable of carrying large numbers of air-launched cruise missiles, including the AGM-158 Joint Air-to-Surface Standoff Missile (JASSM) family. LRASM is derived from that family, sharing a similar general form factor while incorporating features specifically designed to find and attack ships in contested maritime environments.

The B-52 can carry up to 20 JASSMs, and the weapons have the same dimensions, but the government notice does not specify how many LRASMs the bomber would ultimately carry.

This is not the first time the B-52’s LRASM integration has been in the works.

As long ago as November 2019, Naval News reported that $10 million in Fiscal Year 2019 funding had been allocated to study integrating the missile onto the bomber, with Lockheed Martin and the Navy and Air Force expected to work on the effort. At the time, officials said the fielding timeline and the bomber’s eventual missile capacity had yet to be determined.

The U.S. Air Force’s Fiscal Year 2027 budget proposal further outlines plans to integrate the latest variants of LRASM and JASSM onto the B-52, including versions not yet cleared for use on the bomber. According to the document, the effort, which is intended to enable the deployment of next-generation stealthy cruise missiles against targets protected by sophisticated integrated air defense systems, will focus on engineering and manufacturing development, software updates, and weapons integration. Planned work in FY2027 includes incorporating the missiles’ operational flight programs into the B-52’s baseline bomber software, validating safe weapon separation from both wing-mounted stations and the internal carriage launcher, updating armament interfaces, and completing system-safety testing.

LRASM is designed to attack high-value surface vessels at long distances while reducing the exposure of the aircraft launching it. Its guidance combines GPS-assisted inertial navigation with onboard sensors and autonomous target-recognition capabilities intended to help it operate in heavily defended environments. Its imaging infrared seeker supports terminal target acquisition without relying on active radar emissions in that phase of flight. The missile operates with a high degree of autonomy, enabled by an integrated route-planning capability linked to its onboard electronic support measures (ESM) system. LRASM also has a datalink that allows it to get threat updates while in flight. It can also work cooperatively with other LRASMs during coordinated strikes. 

The missile’s precise operational range is not publicly disclosed. However, the baseline LRASM is reported to be able to strike targets at between 200 and 300 miles, in line with the AGM-158A JASSM. The forthcoming C-3 version is expected to have the same reach as the JASSM-ER, which is reported to be around 600 miles.

For the B-52, the addition of LRASM would provide a dedicated anti-ship weapon alongside its established land-attack arsenal. A bomber operating at a considerable distance from a hostile fleet could launch multiple missiles toward maritime targets, complicating an adversary’s air-defense and interception problem. The aircraft’s payload capacity could also allow it to contribute substantial missile volume to a coordinated strike.

The B-52 was previously adapted to carry AGM-84 Harpoon anti-ship missiles, although the weapon is not listed among the bomber’s current publicly documented armament. Compared to the Harpoon, however, LRASM represents a quantum leap in capability, offering drastically greater range, a stealthy design, and the ability to react to threats and adapt in real time. Combined, these traits make for a far more survivable and lethal anti-ship capability.

The B-52 also has a demonstrated naval mine-laying capability through the Quickstrike family of aerial mines. This includes carrying 2,000-pound Quickstrike-ER mines fitted with GPS-aided, winged guidance kits, allowing them to glide to designated points in the water from more than 40 miles away. The system enables the bomber to seed minefields with greater precision while remaining farther from potentially defended waters, threatening enemy shipping routes, port access, and naval movements.

The B-52 effort comes against the backdrop of the Air Force’s newly acknowledged use of LRASM on the B-2, which adds a different dimension to the service’s anti-ship capabilities.

LRASM was also previously integrated on the B-1B, meaning that all three of the Air Force’s strategic bombers will eventually be able to employ it.

The renewed focus on bomber-launched anti-ship weapons reflects the challenges posed by modern naval forces, particularly in the Indo-Pacific. China’s expanding surface fleet, increasingly sophisticated air defenses, and layered anti-access/area-denial capabilities have made the ability to attack ships from a distance an important consideration for U.S. military planning.

LRASM is designed to help address those challenges by combining long-range flight with reduced observability and autonomous terminal targeting. Its onboard sensors and navigation capabilities are intended to help it identify and engage appropriate targets in environments where communications and external targeting support may be limited or contested.

Bomber integration also offers a way to increase the number of potential launch platforms without relying exclusively on tactical aircraft or surface combatants. A B-52 carrying a substantial missile load could contribute to a coordinated attack alongside B-1s, stealth bombers, naval aircraft, and other forces.

The B-52’s payload capacity would make it particularly useful for delivering larger quantities of weapons from outside the most heavily defended areas.

The planned B-52 integration also fits into a broader effort to expand LRASM’s availability across the U.S. military. Publicly discussed integration efforts have included the F-15E, F-15EX, F-16C/D, certain variants of the F-35, and the Navy’s P-8A Poseidon, in addition to established launch platforms, namely the Navy’s F/A-18E/F Super Hornet fighters and the B-1.

Meanwhile, the B-52 fleet is currently preparing for a slew of major upgrades. These include a critical radar overhaul alongside new engines, enhanced communications systems, and other improvements. The scope of these changes is significant enough that the aircraft will be redesignated from B-52H to B-52J. The bombers are also slated to further expand their weapons capabilities, including through the addition of the Long-Range Stand Off (LRSO) nuclear cruise missile. The upgraded B-52Js are expected to remain in service through at least 2050.

Even in its current configuration, the B-52 is particularly well suited to carrying the LRASM, given its substantial payload capacity and ability to launch weapons from standoff distances beyond the reach of enemy air defenses. Its upgraded networking capabilities will greatly enhance its effectiveness by allowing it to operate as part of a broader kill web, drawing on data from multiple platforms and sensors to support targeting over vast distances. In more dynamic operational environments, the bomber’s new radar can generate its own targeting information in real time. The B-2, B-1, and the B-52 all offer distinct levels of penetration and weapons-delivery capability, with the forthcoming B-21 able to push deeper into contested airspace; it will certainly employ LRASM too.

The integration of LRASM onto the B-52 could prove critical to generating the volume of sorties needed to counter China’s expanding naval fleet. With its substantial payload capacity and ability to launch missiles from standoff distances, the B-52 could deliver significant anti-ship firepower across the vast distances of the Indo-Pacific. These missions would likely involve very long-range sorties, making the bomber’s payload capacity, endurance and networking capabilities particularly valuable in sustaining operations against Chinese naval forces.

If the LRASM integration proceeds as planned, the result would be another addition to the U.S. military’s long-range anti-ship arsenal, giving the Air Force’s venerable B-52 a more explicit role in the growing emphasis on striking hostile fleets at a distance.

Retired KC-10 Extender Tankers Could Get A Second Life With North African Mystery Operator

Just over two years after the U.S. Air Force retired the last of its KC-10A Extender aerial refueling tankers, four of those aircraft may be bound for a new career in North Africa for a mysterious end user.

The Air Force Life Cycle Management Center (AFLCMC) put out a contracting notice yesterday “solely for information and planning purposes” with the express intent “to identify potential industry sources that possess the capability, expertise, and facilities to execute the regeneration, one-time flight clearance, depot-level return to service, worldwide ferry delivery, in-country Contractor Logistics Support (CLS), and operational/maintenance training for up to four (4) KC-10 Extender aircraft.”

The KC-10s could be “transferred via Excess Defense Articles (EDA) to a partner nation in North Africa,” the notice adds, without naming the country in question.

The Air Force operated KC-10s between 1981 and 2024. TWZ has reached out to the U.S. Air Force, as well as the U.S. State Department, for more information. The State Department directed us to contact the Pentagon.

The EDA program allows for materiel deemed extraneous to U.S. military needs to be transferred to allies and partners either at a reduced cost or as a grant. The foreign nation in question has to pay for those assets to be delivered, as well as refurbishment, if applicable.

It is important to note here that the Extender, as designed, is capable of refueling receivers using either the boom or the probe-and-drogue method. Tankers equipped for the probe-and-drogue method are, by far, more common internationally. We will come back to this later on.

While we don’t know what the North African country might be in line now to receive the quartet of KC-10s, Egypt and Morocco would seem to be the most likely candidates based on their current and planned aircraft inventories. They are also both major U.S. allies.

The Egyptian Air Force currently does not operate any dedicated aerial refueling tankers. The country is in the process of acquiring two new C-130J-30 Hercules aircraft for use as airlifters, as well as tankers, using the probe-and-drogue method. It does already fly C-130s, but none explicitly configured for aerial refueling duties. Egypt also has a very diverse array of fighters that includes U.S.-made F-16 Vipers that can only be refueled in mid-air via boom.

Morocco’s Air Force also flies F-16s and is in the process of acquiring more. The first new-production Block 72 F-16D for the Moroccan Air Force just flew for the first time earlier this week. Morocco does have an organic aerial refueling capability now, but in the form of C-130s equipped to dispense fuel via probe-and-drogue.

As mentioned, the KC-10 was designed to connect with receivers via probe-and-drogue, as well as boom, and could be used to refuel other tactical jets in Egyptian or Moroccan service. As an aside, fighters belonging to both regularly receive foreign tanker support during exercises, as already seen earlier in this story. Just last month, Chinese YY-20 tankers (also sometimes referred to as Y-20Us) notably did just this in an exercise in Egypt.

— 笑脸男人 (@lfx160219) September 7, 2026

Whichever country may be in line to receive the four KC-10s, there is a question about the current state of those aircraft. Earlier in this story, we talked about the Extender’s capabilities as designed.

McDonnell Douglas (since absorbed into Boeing) delivered a total of 60 KC-10s to the U.S. Air Force between 1979 and 1987. The Extender was derived from the three-engine DC-10 airliner, the last of which was produced in 1989. The Air Force lost one of its KC-10s in an accident in 1987.

Of the remaining 59 KC-10s, 10 were put up for auction in a non-flyable state last year. For reasons that remain unclear, a single engine had been removed from under one of the wings of each of those aircraft. These Extenders were also among the first to be retired, and their booms had been stripped to be used as spares for the examples that remained in service until 2024. Private aerial refueling contractor Omega Air looks to have subsequently won those auctions. Omega also operates two ex-Dutch KDC-10 tankers, which are broadly similar to the KC-10, as well as another DC-10 converted into a probe-and-drogue-only tanker. The company has several Boeing 707-based tankers, as well.

The condition of the remaining 49 Extenders is unclear. Congress included a provision in the annual defense policy bill, or National Defense Authorization Act (NDAA), for the 2026 Fiscal Year that required the Air Force to preserve remaining retired KC-10s, but only stipulated they be maintained “in the same storage condition” they were in as of September 30, 2025. The bill, which was signed into law in December 2025, also made clear that the Air Force could still “dispose” of the aircraft in accordance with existing property management statutes.

Regenerating military aircraft, especially larger ones, back to service can be costly, complex, and time-consuming, even when they are kept in storage in a highly maintained state. In this particular case, acquiring KC-10s via the EDA program, with a very low up-front purchase price, could still be attractive to the right buyer, especially compared to the cost of acquiring new-production tankers.

Personnel at the boneyard at Davis-Monthan Air Force Base apply a protective coating to a KC-10. USAF

For a country like Egypt or Morocco that has never operated a boom-equipped tanker, second-hand Extenders could be a valuable entry point to future aerial refueling capabilities, as well. In general, organic aerial refueling capability is an important force multiplier for any air arm.

There is a possibility that KC-10s could be regenerated not as tankers, but as cargo aircraft, though this seems less likely to be the case. Cargo carrying was also an important duty for the Extenders while in U.S. Air Force service, and they still could operate in this role even when returned to service as tankers.

Though the aging KC-10s were getting increasingly more difficult to operate and maintain, the Air Force’s decision to retire them was still controversial. The Extender was a highly flexible tanker that could carry more fuel than the KC-46s that supplanted them. Clearly, there are others still interested in operating them.

It should be stressed that the AFLCMC contracting notice does not present the transfer of the four KC-10s as a done deal. At the same time, it has revealed that one of America’s partners in North Africa could breathe new life into four of these retired tankers.

U.S. Makes F-35 Push As Portugal Weighs F-16 Replacement

The United States is stepping up its campaign to sell Portugal the F-35. Speaking in Lisbon today, Secretary of State Marco Rubio said the United States would make Portugal a “very competitive” offer to replace its F-16 fleet. The development adds a high-level political push to an increasingly intense competition over the Portuguese Air Force’s next fighter.

Portuguese Foreign Minister Paulo Rangel said after meeting Rubio that Lisbon is seriously considering the American proposal, while emphasizing that other options remain under consideration.

“The Portuguese state will always decide in ‌accordance ⁠with the national interest,” Rangel said at a news conference after the meeting. “There is one point that is also clear: we are seriously considering the F-35 proposal, just as we are considering ⁠others.”

Portugal currently operates 25 modernized F-16AM/BMs, including 21 single-seat F-16AMs and four two-seat F-16BMs, from Monte Real Air Base, or BA5. The Portuguese Air Force, known as the Força Aérea Portuguesa (FAP), has not yet formally launched a replacement competition, but the aging fleet is increasingly becoming the focus of attention in Lisbon.

Portugal acquired a total of 45 F-16A/B Block 15 aircraft through the Peace Atlantis I and II programs.

The first 20 aircraft were delivered beginning in 1994. These were new-build F-16A/B Block 15OCU aircraft, comprising 17 single-seat F-16As and three two-seat F-16Bs, and were used to equip Esquadra 201 “Falcões.”

A second batch followed in 1999, when Portugal received 25 former U.S. Air Force Block 15OCU aircraft. Twenty-one were F-16As and four were F-16Bs, with several intended as attrition replacements or spares. These aircraft had accumulated roughly 3,000 flight hours and underwent an extensive modernization program to bring them to the F-16AM/BM configuration. This means the aircraft are broadly comparable to the U.S. Air Force’s F-16C/D Block 50/52 fleet. 

Esquadra 301 “Jaguares” finally became operational with its upgraded aircraft in 2005, while Esquadra 201 did not receive its upgraded F-16s until 2011.

Since then, the Portuguese Vipers have continued to receive incremental improvements. Their configuration has progressed through several mission-software standards, while the aircraft have been equipped with night-vision goggles, Joint Helmet-Mounted Cueing Systems (JHMCS), and advanced targeting and weapons capabilities.

Among the more important additions are Northrop Grumman Litening II targeting pods, and the ability to employ weapons including GBU-12 Paveway II laser-guided bombs, GBU-31 Joint Direct Attack Munitions (JDAM), and GBU-49 Enhanced Paveway II dual-mode weapons.

Twelve former Portuguese F-16s were transferred to Romania under a deal signed in 2013, with deliveries taking place in 2016 and 2017. Romania subsequently ordered five additional aircraft in 2019.

Structurally, the Portuguese F-16s could potentially remain in service into the mid-2040s. But maintaining their relevance against increasingly sophisticated air forces would require continued investment in avionics, sensors, communications, and self-protection systems.

The F-16AM/BM fleet continues to rely on the old AN/APG-66(V)2 pulse-Doppler radar. Replacing it with an active electronically scanned array (AESA) radar such as Northrop Grumman’s APG-83 would substantially improve detection and tracking performance, but would come at considerable cost.

Portugal faces a choice between continuing to invest in increasingly tired fourth-generation airframes or moving directly into the fifth generation.

Since the end of the Cold War, Portugal has become much more engaged in out-of-area operations and missions in support of NATO.

In the process, the Portuguese F-16 fleet has accumulated an impressive operational record.

The fighters have repeatedly deployed on NATO air-policing missions, including rotations to the Baltic States, Iceland, Romania, and Poland.

The F-35A would give Portugal a fifth-generation fighter built around low observability, sensor fusion, advanced electronic warfare, and networked operations.

The aircraft would also fit naturally into a NATO environment in which an increasing number of European air forces are adopting the F-35.

More than 900 F-35s are already in service or on order across Europe, according to previous comments by U.S. Ambassador to Portugal John Arrigo. Washington has repeatedly argued that joining that community would provide Portugal with a substantial interoperability advantage.

However, European competition includes the Eurofighter Typhoon, Dassault Rafale, and Saab Gripen E, with Airbus preparing an especially aggressive campaign for the Typhoon.

Airbus has said it intends to submit an unsolicited Eurofighter proposal to Portugal in late October or early November. That package is expected to encompass not just the aircraft, but financing, industrial participation and broader military cooperation.

Selecting the American stealth fighter deepens Lisbon’s military relationship with Washington at a time when European governments are wrestling with fundamental questions about their dependence on U.S. military capabilities.

Across the continent, uncertainty over Washington’s stance on NATO is encouraging European allies to examine ways of reducing their reliance on American military technology, even as those same countries continue to increase defense spending and purchase U.S. equipment.

Procurement of the UH-60 Black Hawk underscores the reliance of the Portuguese Air Force on U.S.-made hardware for many of its needs. Portuguese Air Force

If Washington can combine the F-35’s capability advantages with an attractive acquisition and sustainment package, Portugal could find itself facing a difficult choice between the strategic benefits of joining Europe’s growing F-35 fleet and the industrial and political advantages of selecting a European fighter.

The final decision on the replacement of the F-16 will also determine what combat jet spearheads the Portuguese Air Force for the next several decades.

Navy Doubles Down On X-BAT VTOL ‘Fighter’ Drone Development

Shield AI says it is on track to roll out the first prototypes of its X-BAT jet-powered stealth ‘fighter’ drone by the end of this month. Flight testing of this uncrewed aircraft, which is designed to take off and land vertically from a tail-sitting position, is still scheduled to kick off before the end of the year. X-BAT’s core concept was already highly ambitious, but an extremely aggressive timeline to reach some degree of operational capability through the U.S. Navy’s Runway Independent Maritime Expeditionary Strike (RIMES) program has now been disclosed.

TWZ got an update on X-BAT, which we were first to report on in-depth last year, in an interview yesterday with Shield AI’s Armor Harris, Senior Vice President and General Manager of the company’s aircraft division. This came ahead of today’s announcement that the company has received an additional $150 million in funding from the Office of the Under Secretary of War for Acquisition and Sustainment through its Defense Exportability Features program via the Navy. This is on top of the $50 million investment the Navy, in cooperation with the Pentagon’s Defense Innovation Unit, made in X-BAT’s development earlier this year as part of the RIMES effort. Shield AI has committed an equivalent amount of internal funding, for a combined total of $400 million.

“In broad strokes, the last year has been a bunch of collaborative risk reduction with the Navy. So, wind tunnel testing, engine testing, thermal testing, all kinds of stuff to basically take the major risks in the program, [and] burn them down, so we can move confidently into the production design,” Shield AI’s Harris told us. “The last culmination of the risk reduction is the flight testing of the two full-scale prototypes. The first one of those will be done at the end of October.”

“That’s a full-scale vehicle,” he continued. “It’s got the outer mold line, it’s got the F110 engine, the full propulsion path, everything in it.”

To date, Shield AI has only shown models of the X-BAT publicly. A new one displayed at the Navy League’s Sea-Air-Space 2026 exposition in April revealed major changes to the core design. This included a complete reworking of the planform from a ‘cranked kite’ type arrangement to one with a distinctly different arrowhead-shaped profile featuring a straight leading edge with a more dramatic sweep.

The video below includes clips showing the original X-BAT design and the current one.

The aforementioned “propulsion path,” testing of which has already been conducted on the ground, primarily consists of the General Electric F110 paired with an Axisymmetric Vectoring Exhaust Nozzle (AVEN). The nozzle was originally developed in the 1990s for an experimental thrust-vectoring F-16 fighter. Shield AI is using the original AVEN, which had been in storage for decades, to support development of X-BAT. The nozzle will provide pitch and yaw control, with roll control for the drone coming from bleed air routed through thrusters in the drone’s wings.

No runway, no problem.

Shield AI has previously said that the roughly fighter-sized X-BAT will have a maximum range of 2,000 nautical miles and a service ceiling of around 50,000 feet. The company has also said in the past it is targeting an effective combat radius roughly twice that of the F-35, or around 1,340 nautical miles, but also that it could be closer to 1,000 nautical miles. Space has been made within the X-BAT design for a potential in-flight refueling capability, but there is no active work yet to integrate that feature.

In terms of payload, X-BAT’s design includes internal weapons bays roughly the same size as those on the F-35, as well as two external hardpoints under the wings. Those hardpoints are plumbed, meaning that range-extending drop tanks, or even buddy refueling stores to allow the drone to act as a tanker, could be carried. Baked-in modularity and open-architecture mission systems are intended to make it easier to fit various sensors, data links, and other capabilities down the line.

“X-BAT’s really designed to be a multi-role capability, and, if you look out at the 10-20 year time horizon, it’s hard to predict what the future fight is going to look like,” Shield AI’s Harris noted. “We fundamentally believe that multi-role capabilities are critically important. And, so, X-BAT, the reason why it’s sized to where it is is [sic] to be able to carry serious strike weapons internally and externally, in addition to being able to do air-to-air [combat], electronic warfare, and other mission sets.

“You could think of it as like X-35 versus F-35,” he also said yesterday when asked about any expectations now for further changes between the initial pair of prototypes and the final production design.

Lockheed Martin’s X-35 demonstrators are, in very broad strokes, similar to, but distinct from any of the resulting variants of the Joint Strike Fighter. Shield AI has notably already talked in the past about integrating more low-observable (stealthy) attributes to the exhaust end of the design down the line.

“Then we’ll get into flight testing around the end of this year,” Harris added. “We’ll be doing vertical takeoff and landing testing with that [the initial prototypes] to actually prove out and develop the VTOL [vertical takeoff and landing] technology for X-BAT.”

Shield AI’s X-Forge 2 facility at the Newton City-County Airport in Kansas is set to be the main flight testing hub for X-BAT, as well as the focal point for sustainment of the drones. A production facility, X-Forge 3, is also being built in Des Moines, Washington. The company’s original site, X-Forge 1, is in Frisco, Texas.

In terms of the actual flight test campaign, “you remember the X-BAT system has the air vehicle and the launch and recovery vehicle, which is the trailer that it launches and lands from,” Harris said. “Basically, the way the testing works is, we start with the vehicle horizontal, sitting on that launch and recovery vehicle, running the engine. Then we bring it up vertical, run the engine vertically, run the vehicle vertically.”

“Then we have one of the biggest cranes in the world that’s getting set up at our test site in Kansas right now, and we hang the vehicle suspended from that crane and do a bunch of testing while it’s hanging from the crane in free flight,” he continued. “Then we take the crane away, and then we do the actual untethered flights.”

Shield AI’s goal is to fly a fully missionized X-BAT in 2028 and start series production the following year.

On top of that, “the way that the [RIMES] program has been structured is getting to an early operational capability in 2029 is the end goal,” Shield AI’s Harris said.

When asked if this meant that RIMES is aiming “to eventually arrive at not just a demonstration of capability, but a real operationalized capability,” he said that was “correct.”

We will come back to this more later on, but suffice it to say up front, the prospect of X-BAT reaching an operational level of maturity within three years is extraordinarily ambitious, to say the least.

In the meantime, Shield AI has already been testing the mechanisms to “latch and unlatch” X-BAT to the launch and recovery system using an unpowered “battleship” test article, according to Harris. The design of the launch and recovery system has also evolved, and it is now self-propelled, at least to a degree, rather than just being a towed trailer.

“The launch and recovery vehicle is actually critical to the operation of the X-BAT weapon system because it enables survivability on the ground. So when you’re operating in a land-based environment, it enables basically shoot-and-scoot tactics,” Harris also noted. “Enemy transporter-erector-launchers [for missiles] are like pretty hard to find because they’re constantly moving around. Just like X-BAT, when it’s mated onto the launch and recovery vehicle, [it] is always moving around, makes it hard to track, hard to find, hard to destroy.”

The plan now is to “build the one-to-one launch and recovery vehicles to air vehicles. So the air vehicle is always on the trailer. It never comes off of it,” he continued. “Even maintenance to the air vehicle is done while it’s sitting on that launch and recovery vehicle.”

“In fact, we’re actually planning on building more than one-to-one of the launch and recovery vehicles, so that way you can preposition them around different islands, different places in the theater, and have multiple places the aircraft can lily pad from,” he added. “But you’re never putting multiple aircraft onto one launcher and launching them or something like that.”

“When you typically operate a jet, there’s a whole bunch of ground carts and stuff that you bring, like the ground power cart, the ground cooling cart, the air start cart, etc,” Harris further elaborated. “So we’ve moved a lot of those systems onto [the] launch and recovery vehicles, so you don’t have all these separate carts, which is pretty critical when you’re trying to do expeditionary operations.”

“The model for land-based operations is kind of a hub-and-spoke type model. So the squadrons are based at air bases. All the fuel and the weapons are generally based at the air bases, as well. But then you can distribute the aircraft all over the airfield,” he continued. “So, you think about what the enemy’s doing, they’re targeting the runways, they’re targeting the tarmacs, but you can disperse the aircraft around the perimeter of the airfield. You can launch them from the golf course. You can launch them from empty space in the taxiway, etc.”

Harris said that another “spoke” could be X-BATs operating from forward arming and refueling points (FARP). All of this is part of larger concepts of operations for the drone that Shield has been envisioning, and that are not at all limited to deployments at locations on land. Harris noted during the interview that the self-propelled nature of the current launch and recovery system would also help with moving the drones around on virtually any ship with sufficient deck space. This is where the RIMES program, which is separate and distinct from the U.S. Navy’s carrier-based Collaborative Combat Aircraft (CCA) drone ambitions, really comes in.

“I’ll say the fundamental value proposition of RIMES is that if you have a carrier-based CCA, you’re fundamentally constrained by the square footage of the deck of the aircraft carrier,” Harris explained. “So if you are taking an F-18 or an F-35 off, you better be replacing it with better capability per square foot of deck space than the thing that you’re taking off.”

“So, F/A-XX [the Navy’s sixth-generation carrier-based fighter, now to be built by Boeing] is a huge leap in capability, right? Which is why that program makes a lot of sense,” he continued. “The challenge with CCA is: Does it really make sense to take a manned aircraft off of an aircraft carrier and replace it with an unmanned aircraft?”

Shield AI’s argument here is that X-BAT disrupts this core equation by opening the door to a CCA-like capability, or even something more capable, that can be employed in a ship-based mode without sacrificing any crewed aircraft capacity on an aircraft carrier. Shield AI envisions dozens of X-BATs being employed from amphibious assault ships, as well as other kinds of amphibious warfare ships, including expeditionary sea base type vessels, as seen at the top of this story.

“So when you think about the number of carrier air wings that the Navy has to deploy, deploying X-BAT across all these other ships basically significantly increases the number of carrier air wings,” Harris said.

As already mentioned, the current structure of the RIMES includes a target for an early operational capability in 2029, according to Harris. “We have a program defined to get there, and there’s basically milestone-based payments along the way, so as Shield performs and hits milestones, then the Navy kicks in additional funding,” he added.

“I don’t want to get ahead of the Navy, and give you a specific number, but like hundreds to low thousands,” he also said when asked if there was even a very rough planning figure for the eventual size of the RIMES drone fleet.

Many questions remain about X-BAT, which still has to demonstrate the viability of its vertical takeoff and landing capability, which underpins everything else. As we noted in our original in-depth report on this design, the core concept here is not new, and there have been many unsuccessful attempts to operationalize it in the past. There has been skepticism that Shield AI’s effort will succeed where others have failed. The company is of the view that groundwork has now been more firmly laid, including through its own work with its much smaller internal combustion-engine-powered V-BAT tail-sitting VTOL drone, to truly realize a design of this kind.

The performance and capabilities that Shield AI expects from X-BAT once it is flying at all are also ambitious. A high degree of autonomy is also part of the full planned package, which will leverage the company’s already extensive work in this domain with its Hivemind software.

There are also questions about the Navy’s exact plans for RIMES, as well as its broader future drone fleets. Just this year, the service has issued several contracting notices pointing to rapidly evolving views about future carrier-based strike drones and other uncrewed aircraft. New requirements that Naval Air Systems Command (NAVAIR) released in August ostensibly for future CCA-type drones notably pointed more toward something that sounded very much like an advanced uncrewed combat air vehicle (UCAV), as you can read more about here.

Whether the 2029 operational timeframe the Navy is said to be aiming for under RIMES is firm, or even realistic in any way, remains to be seen. The actual definition of what constitutes an “early operational capability” could be very flexible, as well. It is also worth noting here that Shield AI is not the only company currently conducting work under RIMES. Whether the Navy might be planning to acquire more than one design through this program is unclear. We have reached out to the service for more information.

Other services could be interested in any operational capability produced through the RIMES effort, too. TWZ regularly highlights how runway-independent drones would be particularly well-suited to the U.S. Marine Corps’ new expeditionary and distributed concepts of operations. That service is already in the process of acquiring MQ-58B Valkyrie drones from Kratos that will be able to operate from conventional runways. They will also be capable of runway-independent launches, though they will still have to land conventionally. The baseline Valkyrie design lands via parachute.

Aviation Week has reported separately today that Shield AI is looking to pitch the X-BAT to the U.S. Army as a successor to that service’s fleet of MQ-1C Gray Eagle armed drones.

In general, runway independence is of growing interest elsewhere across the U.S. military as threats to large, established bases continue to expand in scale and scope. The proliferation of various tiers of weaponized drones is a particularly significant factor in this, as TWZ just examined in detail this week in the context of the recent withdrawal of B-1 bombers from RAF Fairford in the United Kingdom. Ever more capable cruise, ballistic, and hypersonic missiles are also part of the full threat picture.

The conflict with Iran has also underscored the limits of what can be gained survivability-wise by dispersing traditional fixed-wing aircraft, especially within an existing airbase. As highlighted earlier, X-BAT could be dispersed very differently to nearly anywhere within a facility that can handle the thrust from the F110 engine in hover.

As it stands now, we are set to get our first view of a full-sized X-BAT prototype within the next few weeks as Shield AI continues to gear up for the start of actual flight testing before the end of the year.
