The U.S. Air Force is targeting an approximately $10 million unit price, excluding sensors and certain other systems, for a drone to succeed the MQ-9A Reaper. The cost of a fully kitted-out Reaper today is generally reported to be between $30 million and $50 million. The Air Force is also now pushing to accelerate the program to acquire the new drones, dubbed the Massed Modular Aircraft (MMA), amid what it admits are “concerning” Reaper losses in the course of recent operations against Iran.

Air Force Lt. Gen. Christopher Niemi, the service’s Chief Modernization Officer, told reporters that the goal was for the MMAs to be “closer to half” the cost of a Collaborative Combat Aircraft (CCA), at a roundtable at the Pentagon yesterday, according to Breaking Defense. He also said the service was hoping to see the price tag on its future CCAs fall to around $20 million after full-rate production of those drones gets underway.

Beyond cost, the Air Force has previously said that it wants the MMA drone to perform the same general intelligence, surveillance, and reconnaissance (ISR) and strike missions as the MQ-9A. To that end, stated program requirements to date include a speed of at least 200 knots true airspeed, a munition and sensor payload capacity of at least 2,800 pounds, an unrefueled combat radius of at least 2,300 nautical miles with payload, the ability to self-deploy one-way at least 8,000 nautical miles, and the ability to operate from runways no longer than 6,000 feet. The MMAs also need to be highly modular and use open architecture mission systems to make it easier to integrate new capabilities and functionality down the line.

With all that in mind, Niemi’s MMA cost “estimate includes only the cost of the air vehicle, without being fully missionized,” an Air Force spokesperson clarified after yesterday’s roundtable, per Breaking Defense.

The MQ-9A is out of production, but, as mentioned, the full cost of each one in Air Force service today is generally pegged at between $30 million and $50 million, depending on the sensors, weapons, and other mission equipment they carry. Speaking yesterday, Lt. Gen. Niemi explicitly used the $50 million price point to underscore the MMA program’s unit cost target, as well as explain why the Air Force does not view the newer, in-production MQ-9B as a path to meeting its current needs. General Atomics developed the MQ-9B from the Reaper, but the former is a significantly evolved design with substantial differences from its predecessor.

“If you don’t like losing an MQ-9A that cost on the order of $50 million, with the sensors, you’re probably not going to like losing an MQ-9B at a higher price point,” Niemi said at yesterday’s roundtable, according to a separate report from Air & Space Forces Magazine.

“There’s a, I think, sort of a misconception that because the MQ-9B is in production, we can walk down there with a big fat check and have 100 of them this year,” the general also said, Breaking Defense also reported. “That’s not reality.”

Niemi acknowledged that tradeoffs will have to be made to find an MMA design that is substantially lower cost compared to the MQ-9A.

“You’re going to have to certainly give up something,” he said, per Breaking Defense. “There’s no doubt if we try and pursue the exact same approach that we had with things like the MQ-9, we’re going to get something that costs about the same as an MQ-9.”

However, “what makes the MQ-9 special has nothing to do with the aircraft itself. Like there is no cutting-edge technology for how fast it flies, how high it flies, how far it flies, all that is proven, decades-old technology,” he added, according to that outlet. “So, if you’re focusing on the truck, and you do it in a way where you’re able to make some smart design compromises … we do think you can drive the cost down.”

Niemi said that he expected the MMA, in very general terms, to look much like an MQ-9, including that it would likely also be turboprop powered and have a similarly shaped main wing.

“I think it’s all going to be proven stuff, because that’s how I’m going to drive down the cost so I can get to that goal that I laid out,” Niemi added.

For its part, General Atomics has had choice words in the past regarding discussions about the costs of the MQ-9A and MQ-9B, as well as their capabilities, particularly in light of recent losses. We will come back to the matter of attrition in a moment.

“Some say we need cheaper, disposable aircraft, so that we can use them and throw them away, or lose them and not feel bad about it. No one is talking about actual capability, ready today,” C. Mark Brinkley, a spokesperson for the company, told TWZ back in June after new discussions about a Reaper successor for the Air Force first began to surface. “No one is talking about all of the hard lessons, already learned, about icing and weather and weapons integration. No one is talking about the multiple survivability upgrades available for the existing platforms and the lack of investment in those.”

“These make-believe weapons that don’t exist have the luxury of being anything you imagine them to be,” Brinkley added at that time. “Unscratched lottery tickets, promising all of the win and none of the lose [sic].”

“I think it’s really unfortunate that MMA has been branded as a ‘Reaper replacement’ because it misrepresents what America needs now and what we need later,” he told us last month. “We need an immediate backfill solution to a critical shortage of unmanned MALE [medium altitude, long endurance] ISR/Strike. We need to get going on that now. MMA isn’t a backfill solution, or even a bridge to a backfill solution. This isn’t that.”

Brinkley was speaking here in the context of a discussion about Wildfire, a new drone General Atomics is now developing in response to the MMA requirements.

Wildfire “addresses all of the concerns posed by the MMA solicitation. We can deliver years earlier and maintain the same high quality. You can have everything that makes Reaper special, plus more, at a price that doesn’t break the bank,” Brinkley also told Breaking Defense for its story yesterday.

All of this brings us back around to the matter of MQ-9A losses and the Air Force’s efforts now to accelerate the schedule for the MMA program.

Exactly how many MQ-9As the Air Force has lost due to enemy fire or for any other reason in the course of operations against Iran this year is unknown, but it is reliably reported to be in the dozens. The service is also understood to have lost dozens more Reapers last year during operations targeting Iranian-backed Houthi militants in Yemen. The service is on record saying that its Reaper fleet had shrunk to 135 airframes as of May, down from an official total of 165 as of the start of Fiscal Year 2026. It is also important to note here that these inventory numbers do not include Reapers operated by the Marine Corps or the Central Intelligence Agency.

Air Force officials have offered glowing assessments of the MQ-9A’s performance in operations against Iran, despite these losses, but have also said that the level of attrition is worrisome. That reality, in turn, had major impacts on discussions that led to the current MMA program.

“Although we have plenty of MQ-9As today, we are going through them at a rate that is concerning to us,” Niemi said yesterday, according to Air & Space Forces Magazine. “There’s not a lot of good options to immediately replace those aircraft.”

When the MMA program was first announced in July, the stated goal was to have an initial operational fleet of 20 of the drones in service by 2031. The Air Force is now working to push that timeline to the left, but still sees fielding of the new drones as being around three years away, at least. The service eventually hopes to acquire at least 180 MMAs.

“I can’t buy an MMA today. The reality is, based on the budget and other constraints, that I’m not going to buy a whole lot of MQ-9Bs today either,” Niemi conceded, per Breaking Defense.

It is important to remember here that the Air Force has already tried multiple times to develop a replacement for the MQ-9 without success. In that time, the idea of what a successor to the Reaper would look like has changed dramatically. As we’ve written previously:

“The Pentagon has long worked on the basis that a future conflict with a peer rival, and especially with China in the Pacific, would see it facing highly robust anti-access/area-denial (A2/AD) scenarios. With that in mind, previous Reaper replacement studies had suggested that low observability would need to be incorporated into the design.”

“The latest thinking seems to reject that, or at least reorient the program toward a lower-cost platform of the kind that the Air Force would be able to field in mass, as well as to absorb the anticipated attrition in a high-end conflict. This does not preclude this airframe from featuring low-observable elements. In fact, it most likely will. But those would be more aggressively balanced against cost.”

MMA is also looking at a wider slate of potential vendors. General Atomics, which has long had a monopoly on the U.S. MALE combat drone market, is not the only one angling now for an MMA contract.

Overall, as we have previously written in the context of the Air Force’s latest effort to move beyond the Reaper:

“…the U.S. drone landscape has changed considerably in terms of manufacturers. A few years ago, Northrop Grumman, Lockheed Martin, and General Atomics would have been seen as the front-runners for the MQ-9 replacement. Now, there are more contenders, often with a founding focus on rapidly scaling up production at low cost. Still, these firms have much to prove, especially considering the risk in replacing an aircraft as important as the MQ-9. At the same time, in the more advanced drone space, the legacy defense ‘prime’ contractors are also making major progress in leveraging new technologies to reduce production costs and migrating away from exquisite, very expensive drones as their default offerings.”

The possibility was reportedly raised yesterday that the MMA program could ultimately lead to the fielding of multiple types of drones through successive incremental development cycles. This is exactly how the Air Force is running its CCA program now.

With the Air Force now pushing for a more aggressive schedule for the MMA effort, more details about the designs it is considering may begin to emerge relatively soon. The service certainly has a pressing need already for these drones after so many MQ-9A losses.

The post USAF Wants MQ-9 Reaper Successor At A Fraction Of The Cost At $10M Each appeared first on TWZ.

The U.S. Air Force is seeking an anti-aircraft gun system to help defend its air bases around the world from drones and cruise missiles. The Request for Information (RFI) about these systems, posted on the government’s contracting website on Thursday, is part of a larger Air Force effort to play a greater role in air base defense via ground-based air defenses (GBADs), a capacity traditionally performed by the Army. As a result, the Air Force currently has no such systems. Now it is interested in changing that.

The request comes as the war against Iran exposed gaps in how the U.S. can provide effective, sustained air defenses for its foreign installations and amid concerns about a future fight against a peer competitor like China or Russia.

“The Government is conducting market research to identify potential industry sources capable of providing solutions for a Ground-Based, Medium-Caliber Gun Weapon System that fires affordable munitions, enables defense against air and missile threats with an initial focus on subsonic cruise missiles (CM) and Unmanned Aircraft Systems (UAS) to provide persistent defense in support of [the] United States Air Force,” the RFI notes.

The RFI doesn’t stipulate what it considers a medium-caliber round; however, according to the Army, the list includes 20mm, 25mm, 30x113mm, 30x173mm and 40mm shells.

“To effectively assess and compare air defense weapon system performance, there are 15 critical baseline operational and technical parameters that must be analyzed in unison,” the RFI explains.

“These key metrics begin with the system’s Salvo Probability of Kill (Pk) evaluated against both Cruise Missiles (CM) and Unmanned Aircraft Systems (UAS) Groups 1-5 at maximum range and altitude, ensuring robust lethality against diverse modern threats,” the RFI notes.

A salvo probability of kill measures how effectively a salvo, as opposed to a single shot, defeats a target. 

The following chart displays the weight, normal operating altitude and speed of the five drone group classifications.

The Air Force wants this system to be “rapidly deployable, maintaining a lightweight, modular, and transportable footprint that can be swiftly projected into austere theater environments to meet emergent threats.” The RFI does not provide further details of how the Air Force is looking to transport these systems; however, the service relies on its fleets of C-130 Hercules, C-17 Globemaster III and C-5 Galaxy transport aircraft to move equipment. The size and weight of the systems determines which kind of aircraft can transport it.

These systems could also be moved by truck or ship or on their own if self-propelled, but those options also incur a cost in terms of the timeliness of delivery, and can be impossible for rapid global deployments.

A key point of evaluation will be the overall cost of the munitions. The Air Force wants to ensure that the shell’s velocity and terminal effects “are maximized without driving the cost-per-engagement to unsustainable levels or exceeding the physical constraints of the host platform,” the RFI states. We’ll discuss these factors in more detail later in this story.

The service is also looking for the integration of “the right mix of radar, electro-optical, infrared, or radio-frequency sensors—to ensure reliable target acquisition and tracking across varying weather conditions, environments, and countermeasure scenarios.”

As we noted at the top of this story, the Air Force is seeking to improve its organic ability to defend its bases. This has become “an increasingly high priority” for the service, Air Force Secretary Troy E. Meink told Congress on May 20.

“The Air Force is developing organic air and missile defense capabilities, including Counter-small Unmanned Aircraft Systems (C-sUAS) to defend our air bases in all theatres [sic],” Meink stated in his written testimony. “The fielding of the Air Base Air Defense Systems (ABADS) missile defense capability, including kinetic defenses, at overseas main operation bases contributes to joint layered defense but does not reduce the need for increased joint investment in air and missile defense. We will continue to work judiciously for the development and procurement of these critical defensive capabilities.”

In its Fiscal Year 2027 budget request, the Air Force is seeking about $1.4 billion for a missile defense variant of the Air Base Air Defense Systems (ABADS), according to Air & Space Forces Magazine. In addition, the Air Force also requested $51.8 million in procurement funds for its Small Unmanned Air Defense Systems (SUADS) in Fiscal Year 2026, according to the Air Force Fiscal Year 2026 budget justification book. 

The war against Iran and the Ukraine war have, in particular, illustrated the challenges of defending against drones and cruise missiles.

Iran launched thousands of these weapons against U.S. air bases and a wide range of critical infrastructure targets in Bahrain, Israel, Iraq, Jordan, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates. It also launched hundreds of ballistic missiles.

Taken in concert, these attacks have resulted in the deaths of at least nine U.S. troops, more than 760 injuries and the destruction of aircraft, radars and other critical equipment as well as widespread damage to the Middle Eastern nations Iran has targeted.

Concerns about the tremendous expenditure of U.S. interceptors exacerbating the stress on America’s magazine depth of these high-end defensive weapons are an issue that TWZ has raised frequently for years.

There are two facets to potential use of gun systems for base defense. The first is that in complex air defense environments, it provides an inner, last line of defense against incoming threats. If the outer layers fail to take down the target or that target is not considered a priority over others, a hard-kill gun system offers a predictable and relatively reliable fallback. The gun system would become even more important if interceptor stocks run low, even temporarily, and those weapons need to be rationed for higher-end threats. With the outer defensive rings collapsing, the inner becomes far more important.

For small drones, that interceptors would not be effective with anyway, the gun system can take them down in localized air defense scenarios. Then there is also defending bases in lower threat areas where there are not additional layers of SAM systems. A gun system can provide a core aerial defense against lower-end, lower-density drone and cruise missile threats without costing huge sums of money or requiring a huge logistical footprint.

Beyond that, there is a direct cost comparison argument, but again, that is in a vacuum and a gun system cannot take the place of a multi-layered air defense system without inviting huge risk. Still, the engagement cost comparison is worth mentioning.

High-end, expensive, difficult-to-manufacture air defense weapons, like Patriot PAC-3 MSE, are clearly inefficient against drones. For instance, a mass-produced Iranian Shahed-136 can cost about $35,000 to $50,000, while a Patriot PAC-3 can run about $5 million and takes years to procure. By comparison, the cost-per-engagement efficiency of gun-based air defense systems, designed to defend against drones and subsonic cruise missiles, is far greater. One example of how this plays out is the cost of firing the Army’s Centurion Counter-Rocket, Artillery, Mortar (C-RAM) system. It is a ground-based version of the Phalanx Close-In Weapon System (CIWS) used on various U.S. and foreign warships, and is armed with a six-barrel 20mm Vulcan Gatling-type cannon firing M940 rounds. Those self-destructing rounds currently have a price tag of $80.70, according to the Army’s Fiscal Year 2025 budget request. This means a two-second burst from a Centurion, at a rate of fire of 4,500 rounds per minute, would cost just over $12,100.

Again, this is not a strict apples-to-apples comparison, but it can become a bigger factor during prolonged conflicts when high-end weapons stocks begin to run short. It’s also worth noting that drone interceptors are a rapidly growing capability set that are a lower-cost option for swatting down one-way attack drones and even some cruise missiles. Systems like Coyote have been in service for years with the Pentagon and have been protecting bases overseas with strong results. Even cheaper systems are emerging out of lessons learned in Ukraine. All of these systems have their own advantages and disadvantages, but pairing them with a new gun system would likely have synergistic effects. Overall, deploying densely layered short-range air defenses is becoming increasingly important in its own right, at least in high-threat areas.

Ukraine has a great deal of experience with the costs and prioritization of air defense capabilities. The country faces daily attacks by Russian missiles and drones, which is causing mounting casualties and destruction. This ceaseless bombardment has almost completely depleted Ukraine’s supply of Patriot interceptors, leaving it largely defenseless against ballistic missiles. As we noted yesterday, Ukraine is also running short of air-to-air missiles its Air Force F-16s use to swat down drones.

However, Ukraine has also relied heavily on a wide array of gun-based air defense systems, including the German-made Gepard self-propelled anti-aircraft guns (SPAAG). Based on the chassis of the Leopard 1 main battle tank, Gepards feature twin radar-aimed 35mm automatic cannons, mounted on a single turret. The German variant sports an S-band search radar and a Ku-band tracking radar. These radars are critical to the Gepard’s ability to locate, track, and engage targets at night and amid poor weather conditions.

The success of the Gepards in Ukraine have helped spur new global interest in SPAAGs.

The following video shows a Gepard blasting an Iranian-made Shahed-136 out of the sky.

The Air Force force is also looking at directed energy weapons like lasers for force protection and especially for defending bases overseas. While gaining traction across the services due in large measure to the much lower cost of delivering effects, these systems are still works in progress. Gun-based air defenses, on the other hand, are mature and proven, and modern precision-guided, programmable ammunition makes them even more efficient and effective.

Beyond the cost, high-end air defense systems — including their component sensors — though portable, are generally fixed to a specific location. That makes them vulnerable to attack. This has been the case in both the war against Iran and Ukraine. The same concerns hold true of aircraft. Both conflicts have shown aircraft vulnerability to drones when parked out in the open. Ukraine’s Operation Spider Web attack on Russian strategic bombers last year in particular shed light on this issue, which we have been sounding the alarm on for a long time.

For years now, U.S. military officials have often pushed back on the utility and cost-effectiveness of investing more in the physical hardening of bases and other critical facilities, especially shelters to shield aircraft from drones and other threats. However, that is beginning to change. In February, the Pentagon released new guidance about hardening, which “does not mean enclosing an entire facility, but selectively introducing obstacles that disrupt predictable aerial access,” the document explains. “Even modest obstacles can deter low-cost, consumer-grade drones and force higher-risk flight profiles.”

In addition to these challenges, the Air Force is also facing the headwinds of an overall lack of U.S. short-range air defense capabilities, a concern we have been highlighting for years. Currently, there are three gun-based SHORAD systems being fielded by the U.S. military. These include the aforementioned Centurion C-RAM systems.

The Army also uses the Sgt. Stout, an air defense system based on the 8×8 Stryker light armored vehicle. The Sgt. Stout has a turret that can be fitted with up to two four-round launchers for Stingers. Those launchers can also be swapped out for ones that can be loaded with a pair of millimeter-wave radar-guided AGM-114L Hellfire missiles. The turret also has a 30mm XM914 automatic cannon, which can fire proximity-fuzed airbursting rounds against drones and other aerial threats, and a 7.62x51mm M240B machine gun.

The Marine Air Defense Integrated System (MADIS) is armed with 30mm cannons and M240C coaxial machine guns in remote weapon stations (RWS). The RWS on one of the two vehicles is also configured to fire Stinger missiles for a spectrum of ground-based air defense scenarios.

The Army may have additional gun-based systems on the way. In July, the service put out a request for information to companies that can provide a new gun-based air defense option, using a 50mm cannon system to track and defeat Group 1, 2 and 3 drones.

A few weeks later, Northrop Grumman introduced its Raid Hunter 50mm GBAD system, which it said “combines proven Chain Gun® technology, precision‑guided 50mm ammunition and a networked, interoperable system controller to deliver powerful protection against high-volume, mixed-threat aerial raids. It is designed to defeat a range of aerial threats including high‑priority cruise missile threats, unmanned aerial systems (UAS), and other advanced threats.”

We’re introducing Raid Hunter, our newly named 50mm gun-based air defense system designed to defeat mass, mixed aerial raids with cost-effective interceptors and deep magazine effectors which can be delivered to the warfighter at scale.

There are foreign options should the Air Force want to go that route. For instance, German arms maker Rheinmetall makes the popular Skyranger 35 gun system, which is a turret that can fit on a wide array of armor hulls.

The Skyranger 35 “is equipped with a KDG 35/1000 revolver cannon in 35 mm x 228 caliber with a firing rate of 1,000 rounds per minute,” according to Rheinmetall, which began delivering these to Ukraine in January. “It has an effective range of up to 4,000 meters and a high degree of commonality with the Oerlikon Revolver Gun Mk 3. Thanks to AHEAD technology, the Skyranger 35 is airburst-capable. In the future, it will also be possible to equip it with modern guided missiles.”

Skyranger 35s mounted on Cold War-era Leopard 1 tanks have just emerged on the battlefield for Ukraine.

You can see a video of that system below.

It seems that Ukraine's 1020th Anti-Aircraft Missile Regiment which belongs to the Ground Forces has taken delivery of the first Skyranger 35 SPAAGs mounted on a Leopard 1 chassis made by @RheinmetallAG.

Skyshield is the fixed placement cousin of this system and has been bought by a number of nations.

This is just one example of a large number of potential offerings that could fit the USAF’s interests, from both domestic and foreign origins.

As we discussed earlier in this story, the U.S. is already facing a challenge defending against Iranian threats. A war with China would be more devastating and, when it comes to the Air Force protecting its bases, require far more robust defenses. At the same time, the Air Force is still very early in the process of taking on more responsibility for protecting its assets.

Parties have until 5 p.m. Oct. 9 to submit their proposals to the Air Force for a gun-based air defense system. With limited options and the service pushing to address its growing desire for organic air defenses, it will be interesting to see who comes forward and what systems they offer. We will provide more details about this effort when they become available.

The post U.S. Air Force Seeks Anti-Aircraft Guns To Protect Its Overseas Bases appeared first on TWZ.

The first F-15EX Eagle II destined for permanent assignment at Kadena Air Base in Okinawa departed Boeing’s St. Louis, Missouri, facility on August 28, 2026. The aircraft left St. Louis for the 142nd Wing at Portland Air National Guard Base, Oregon, where it will undergo final staging and integration preparations before its eventual deployment to the sprawling Okinawa installation it will call home. The Oregon unit is acting as a coordination and preperation unit for the 18th Wing, a function you can read more about in our interview with the wing’s commander.

This departure represents a critical, long-awaited milestone for the 18th Wing, which has been working toward the permanent stationing of the service’s most advanced Eagle variant to replace its now-withdrawn F-15C/D fleet. The arrival of the F-15EX in Japan, expected to begin in fiscal year 2027, which begins on October 1, 2026, will be a central pillar in the Air Force’s modernization of tactical airpower in the Indo-Pacific region.

EXciting progress for F-15EX!

We've delivered the 22nd F-15EX to the @usairforce. The aircraft will be the first F-15EX destined for @KadenaAirBase in Japan. pic.twitter.com/RlrTKuCCFl

“This is an important next step toward bringing the F-15EX home to Kadena,” said Brig. Gen. John Gallemore, 18th Wing commander, in an Air Force release. “Our team is ready to welcome the F-15EX, and this is another milestone that brings us closer to putting this capability in the hands of the airmen who will fly, maintain and employ it from Japan.”

The first F-15EX for Kadena’s 18th Wing, serial 22-0022, was noted flying test sorties from St. Louis in early August, initially in primer paint. By the middle of the month its was flying with its full livery, including the famous “ZZ” tail code.

The F-15EX is a significant jump in capability over the legacy Eagles. With modernized avionics, flight controls, an expanded electronic warfare suite, and increased weapons carriage — as well as potentially new and longer-reaching weapons — the jet is well-suited to operating in the vast Western Pacific. As Kadena prepares for the permanent arrival, the 18th Wing plans to integrate the EX with regional allies, including the Japan Air Self-Defense Force, building upon existing bilateral training exercises.

Two active-duty squadrons of F-15EXs are set to be established at Kadena, taking the place of units previously based there that had flown F-15Cs. The Air Force has been deploying F-15Es, F-22s and other fighters to the base on a rotational basis to fill the gap in the meantime.

The F-15EX will give U.S. forces in the Indo-Pacific a high-capacity platform that complements the fifth-generation F-22 and F-35. With its ability to carry large air-to-air and air-to-surface payloads, the Eagle II can serve as a long-range “missile truck,” extending the reach and firepower of stealth aircraft operating closer to contested airspace. Its open-architecture systems also allow it to incorporate new sensors, weapons, and electronic warfare capabilities more readily than the aging F-15C/D fleet.

The aircraft’s value is also tied to its role in networked operations. Exercises such as Valiant Shield have demonstrated how the F-15EX can work with uncrewed aircraft like the  MQ-28 Ghost Bat, pointing toward mixed formations in which crewed fighters provide weapons, sensing, and command-and-control capacity for autonomous wingmen. Operating from strategic locations such as Kadena, the Eagle II could help the Air Force generate more combat power across the vast Pacific while reducing the burden on its limited number of stealth fighters.

Kadena will become the second Air Force location with combat-coded F-15EX aircraft, following the Oregon Air National Guard’s 142nd Wing.

The Air Force has previously announced plans to stand up National Guard F-15EX squadrons in California, Louisiana, and Michigan. Most recently, the Air Force announced plans to put F-15EX fighters at Seymour Johnson Air Force Base, North Carolina, to replace older F-15E Strike Eagle jets that will move to Whiteman Air Force Base, Missouri.

While the movement of this first Kadena-bound F-15EX is a positive step, the wider Eagle II program is currently navigating some issues. According to a new Pentagon selected acquisition report released in August, the Air Force’s decision to aggressively expand its F-15EX fleet from 129 to 267 jets — intended to recapitalize the older F-15E force — has introduced substantial cost and schedule uncertainties that officials are now scrambling to manage.

The report warns that the extended acquisition strategy, which shifted from eight production lots to 12, will require Boeing to execute a “major technical refresh” to combat diminishing manufacturing sources and material shortages. As systems like the radar, mission computer, and engines face potential obsolescence over the now-lengthened production timeline, the service faces what the report characterizes as a “significant redesign effort.” Program managers are planning to mitigate these risks by integrating upgrades through operational flight program releases scheduled between 2031 and 2035, a strategy they describe as a “structured, risk-reduced pathway” to avoid production line gaps.

Compounding these technical challenges are tangible production delays, largely stemming from a labor strike at the St. Louis plant from August to November 2025. The report notes that these are “unrecoverable delays,” forcing a cascading schedule slip. While Boeing was contracted to deliver all 12 jets from Lot 3 by early 2026, the company will only be able to field half of those by the end of the year. This has directly impacted the timeline for the Kadena deployment, which was originally envisioned for earlier in 2026, and has left the Air Force relying on “bridging strategies” and rotations to cover operational requirements until the Eagle IIs can fully stand up in Okinawa.

The Pentagon is now moving toward an aggressive production ramp-up, tasking Boeing to hit a rate of two jets per month. Keeping the F-15EX schedule on track will be a challenge, however, requiring successfully navigating ongoing parts shortages for critical systems, all while balancing the needs of foreign military sales customers who are also integrated into the supply chain.

For the 18th Wing, the arrival of the first F-15EX will bring a major advance in capabilities in a part of the world that needs them badly. At the same time, the program’s overall trajectory suggests that the wider transition to the new Eagle will come with some complex logistical and industrial challenges.
