US Air Force to Replace Oldest F-35s Instead of Upgrading Them
The US Air Force opts to retire early F-35A jets, focusing on new purchases over expensive Block 4 upgrades amid delays and cost overruns.
A Pragmatic Pivot: Why the U.S. Air Force Is Replacing Its Oldest F-35s
The F-35 Lightning II stands as the centerpiece of modern air combat for the United States and its allies. As a fifth-generation, multirole fighter, its development and deployment represent one of the most ambitious and expensive defense programs in history. The U.S. Air Force’s long-term vision includes acquiring a massive fleet of 1,763 F-35A variants, making it the backbone of its tactical airpower for decades to come. This long-term plan, however, is now facing a significant strategic adjustment.
In a notable shift, the Air Forces has decided to phase out its earliest F-35A models rather than subject them to a complex and costly modernization process. This move, detailed in a congressionally mandated report, involves divesting the older, non-combat-capable jets instead of upgrading them to the advanced Block 4 standard. This decision is not a retreat from the F-35 program itself but rather a calculated course correction, driven by the immense technical and financial challenges associated with the Block 4 upgrade. It signals a pragmatic choice to prioritize the acquisition of new, factory-fresh aircraft over the difficult task of retrofitting the oldest airframes.
The Rationale: Cost-Effectiveness Over Complex Retrofits
The core of the Air Force’s decision lies in a simple, yet critical, calculation: it is more efficient to buy new F-35s than to upgrade the old ones. The Military-Aircraft targeted for replacement are from the early low-rate initial production (LRIP) phases. These jets were built before the design was finalized and lack the full combat capabilities of their more modern counterparts. Bringing them up to the latest Block 4 configuration would require extensive, invasive, and expensive modifications.
This strategy is also an attempt to move away from what has been termed “acquisition malpractice”, the practice of developing, testing, and producing a weapons system concurrently. This approach has historically led to costly retrofits as design flaws are discovered after aircraft have already been built. By focusing on procuring new F-35s built with the latest technology from the ground up, the Air Force aims to field a more reliable and capable fleet faster. The service is looking to significantly ramp up its procurement rate, with a goal of acquiring as many as 80 F-35As annually.
Lockheed Martin, the F-35’s Manufacturers, has indicated a potential production capacity of up to 100 F-35As per year by fiscal year 2030. This industrial capacity supports the Air Force’s strategy, making the replacement plan a viable path toward achieving its total fleet objective of 1,763 aircraft without sinking more resources into the most problematic early models.
The Troubled Block 4 Upgrade
The decision to replace the older jets is inextricably linked to the severe difficulties plaguing the Block 4 modernization program. Block 4 is a critical but massive undertaking, designed to equip the F-35 with the capabilities needed to counter advanced future threats. The upgrade includes over 75 major improvements, such as increased missile capacity, next-generation electronic warfare systems, and enhanced target recognition.
However, the program has fallen far behind schedule and ballooned in cost. A Government Accountability Office (GAO) report painted a stark picture, revealing that the Block 4 upgrade is five years behind schedule and a staggering $6 billion over budget. Full integration of all planned capabilities is not anticipated until 2031. These persistent delays and cost overruns have forced the F-35 program to consider reducing the overall scope of the modernization effort.
A key technical hurdle has been the development of Technology Refresh 3 (TR-3), the new hardware and software core intended to provide the necessary computing power for Block 4’s advanced features. TR-3 has faced its own significant developmental challenges, creating a bottleneck for the entire modernization pipeline. In 2024, these issues contributed to Delivery delays for all new F-35s, with an average delay of 238 days per aircraft.
The attempt to make the F-35 a jack-of-all-trades has been cited as a fundamental challenge, with one analyst noting it was a flaw to try and make the aircraft do too much. This complexity is now manifesting in the difficulties of the Block 4 upgrade.
Broader Implications for the Future Fighter Fleet
This strategic pivot on the F-35 is part of a larger evolution in the Air Force’s approach to its fighter fleet. The service is moving toward a mixed-fleet model, balancing the high-end capabilities of the F-35 with other, more affordable aircraft. This is evidenced by the increased procurement of the Boeing F-15EX Eagle II, a modernized fourth-generation fighter intended to complement the F-35 and handle missions that do not require stealth.
The high operating and maintenance costs of the F-35 have long been a point of concern. Former Air Force officials have described the jet as a “Ferrari” that shouldn’t be used for daily, low-end fights. By investing in a mix of aircraft, the Air Force can optimize its fleet for a wider range of missions and manage sustainment costs more effectively.
Furthermore, this decision allows the Air Force to focus resources on the future. The service is already looking ahead to its sixth-generation fighter, part of the Next-Generation Air Dominance (NGAD) program, and the integration of Collaborative Combat Aircraft (CCAs), or “drone wingmen.” Divesting the oldest F-35s frees up funding and logistical capacity that can be redirected toward these next-generation priorities, ensuring the U.S. maintains its edge in air superiority for decades to come.
Conclusion: A Pragmatic Path Forward
The U.S. Air Force’s decision to replace its earliest F-35A models is a clear-eyed response to the realities of a complex and troubled modernization program. Faced with the immense cost and technical risk of upgrading its oldest jets, the service has chosen a more pragmatic path: accelerate the acquisition of new, fully capable aircraft. This move aims to avoid repeating past mistakes and ensures that the warfighter receives the most advanced technology available without delay.
This strategic shift underscores a broader evolution in military procurement, prioritizing efficiency and future-readiness. By balancing the F-35 fleet with complementary aircraft like the F-15EX and investing in next-generation systems, the Air Force is building a more resilient and adaptable fighter force. The F-35 remains the cornerstone of that force, but this decision ensures the foundation is built with the strongest, most modern assets available.

Airbus Delivers First NH90 Standard 2 to France
Airbus Helicopters delivered the first NH90 Standard 2 to France on July 30, 2026, launching an 18-aircraft order for special forces.
Airbus Helicopters has delivered the first NH90 Standard 2 tactical transport helicopter to the French Armament General Directorate (DGA), initiating a phased rollout of 18 specialized aircraft designed for special operations.
The handover took place on July 30, 2026, at the manufacturer’s facility in Marignane, France. According to a press release from Airbus, the aircraft will be operated by the French Army Light Aviation (ALAT) 4th Special Forces Helicopter Regiment based in Pau. The Standard 2 configuration builds upon the existing NH90 Tactical Transport Helicopter (TTH) platform, introducing advanced digitalization and modular communication systems intended to support complex missions in degraded environments.
Technical upgrades and operational capabilities
The NH90 Standard 2 incorporates several hardware and software modifications tailored to the requirements of special forces operators. Key integrations include the Safran Euroflir 410 D electro-optical system and a new digital map generator, which together enhance situational awareness for the flight crew. The airframe features enlarged rear sliding windows designed to accommodate self-protection guns, alongside provisions for a third crew member station.
With the addition of external fuel tanks, the variant achieves an operational range exceeding 1,000 kilometers. The aircraft architecture also emphasizes rapid integration of future technologies.
Integrating a new communications system is a complex and costly process. The NH90 Standard 2 comes pre-equipped with antennas and cabling to accommodate any type of new radio installation. Voice, data, satellite transmission, everything can be installed quickly and easily in the helicopter, which also has the capacity to control drones. It’s revolutionary.
The quote, provided by an unnamed officer from the 4th Special Forces Helicopter Regiment in the Airbus announcement, highlights the platform’s shift toward network-centric operations.
Program timeline and international adoption
The development of the Standard 2 variant began following a contract issued in October 2020 by the NATO Helicopter Management Agency (NAHEMA). Flight testing for the initial prototype commenced in June 2024, leading to the start of production in early 2025. Airbus expects to complete deliveries of the 18 helicopters ordered by France by mid-2029.
The configuration has already secured international interest. In December 2025, Spain joined the program with an order for 31 NH90s in a similar standard.
We are honoured to deliver this NH90 Standard 2 to the French armed forces. This new standard builds upon the proven capabilities of the NH90 TTH with new breakthrough features designed specifically for special forces. More than ever, special forces operators will be able to execute their difficult missions in the toughest environments.
Matthieu Louvot, CEO of Airbus Helicopters, noted that Spain’s participation in developing features for crew situational awareness indicates the new standard is positioned to become a benchmark for special forces globally.
AirPro News analysis
The delivery of the NH90 Standard 2 highlights a growing requirement among NATO members for rotorcraft that function as integrated command and control nodes rather than simple troop transports. By pre-equipping the airframe with modular cabling and antennas, Airbus and NAHEMA are addressing a historical pain point in military aviation: the prohibitive cost and downtime associated with retrofitting communication suites. The explicit inclusion of drone control capabilities within the helicopter’s systems reflects a broader tactical shift, where manned rotorcraft will increasingly operate in tandem with unmanned aerial systems to extend sensor reach and reduce risk in contested airspace.

Cessna SkyCourier UX Uncrewed Cargo Concept Unveiled
Textron Aviation and Merlin unveiled the Cessna SkyCourier UX, an autonomous cargo concept for USAF contested logistics missions.
Textron Aviation Inc. and autonomous flight developer Merlin, Inc. unveiled the Cessna SkyCourier UX concept aircraft on September 14, 2026, proposing an uncrewed, forward-loading cargo variant of the twin-engine utility turboprop designed specifically for Military-Aircraft logistics.
Introduced at the Air & Space Forces Association (AFA) Air, Space & Cyber Conference in National Harbor, Maryland, the concept aims to address the United States Air Force (USAF) requirement for sustaining distributed forces in contested environments. According to a joint press release, the design removes the traditional cockpit to maximize cargo utility, targeting the gap between small tactical drones and heavy military airlifters.
Designing for contested logistics
The military concept of contested logistics focuses on resupplying forward-deployed units in areas where traditional heavy transport aircraft face high threat levels or lack suitable runway infrastructure. The Cessna SkyCourier UX is intended to fulfill the “Last Tactical Leg” of these supply chains without risking aircrew.
To optimize the airframe for autonomous cargo operations, the concept design eliminates the flight deck entirely. This alteration enables a forward-loading architecture featuring a large nose opening and an aircraft kneeling capability. The companies stated that these modifications, combined with integrated loading systems, are designed to facilitate rapid cargo handling in austere locations.
The uncrewed variant retains the core capabilities of the FAA certified Cessna SkyCourier platform. It is projected to carry a payload of approximately 6,000 pounds and accommodate up to three LD3 Cargo-Aircraft containers.
Integrating the Merlin Pilot system
The autonomous capabilities of the Cessna SkyCourier UX rely on the Merlin Pilot software system. Merlin has previously integrated and tested its autonomous flight technology on other Textron Aviation platforms, including the Cessna Caravan and Beechcraft King Air.
Matt George, CEO and founder of Merlin, emphasized the necessity of combining established technologies for military applications.
“Solving contested logistics today takes proven autonomy and a proven airframe. This concept pairs it with a proven platform, the Cessna SkyCourier, to explore what an aircraft could look like when it’s designed around autonomy and cargo instead of a crew.”
Bob Gibbs, Vice President of Defense and Special Mission Sales at Textron Aviation, noted that the concept reflects a commitment to addressing real-world mission challenges by adapting certified products for distributed operational environments.
Current program status
While the base Cessna SkyCourier is an active production aircraft, the UX variant currently exists as a design study and scale model. Textron Aviation and Merlin have not yet announced a launch customer or established a timeline for prototype manufacturing and production.
The development of the concept will likely depend on further engagement with the USAF and other defense operators regarding their specific requirements for autonomous tactical airlift.
AirPro News analysis
We view the Cessna SkyCourier UX as a pragmatic approach to the military’s autonomous logistics problem. By leveraging an existing, FAA-certified Part 23 utility aircraft rather than developing a clean-sheet design, Textron Aviation and Merlin can significantly reduce development risk and timeline. The removal of the cockpit to allow front-loading is a structural challenge, but it solves the primary limitation of side-loading cargo doors in austere environments where specialized ground handling equipment is unavailable. The success of this concept will hinge on the military’s willingness to fund the structural modifications required to turn the standard SkyCourier into a dedicated uncrewed freighter.

US Air Force Names FQ-42A Vengeance and FQ-44A Fury CCAs
The U.S. Air Force officially designated its first two CCAs, targeting 500 platforms in service by 2032 out of a 1,000-unit buy.
The U.S. Air Force has officially designated its first two Collaborative Combat Aircraft (CCA) as the FQ-42A Vengeance and the FQ-44A Fury, signaling a rapid transition toward autonomous mass in the 2030s. Secretary of the Air Force Troy Meink announced the names on September 14, 2026, during the Air & Space Forces Association Air, Space & Cyber Conference in National Harbor, Maryland.
In a press release issued by the service, the naming marks a major milestone for the CCA program, which aims to field a large fleet of semi-autonomous unmanned combat aircraft to fly alongside crewed fighters. The announcement follows the June 2026 award of production contracts to General Atomics Aeronautical Systems and Anduril Industries for the first increment of the program.
Official designations and manufacturer responses
The General Atomics FQ-42A will carry the name Vengeance. The manufacturer had previously referred to the design internally as the Dark Merlin, a moniker that will now be retired in favor of the official military designation.
General Atomics spokesman C. Mark Brinkley welcomed the official designation. According to reporting by Air & Space Forces Magazine, Brinkley stated that the company appreciates when customers name their aircraft, adding that the name Vengeance effectively summarizes the platform’s purpose.
The Anduril Industries FQ-44A has been officially named Fury. The defense technology company had already been utilizing the Fury name internally during the development and prototyping phases of the aircraft.
Ambitious procurement targets for autonomous fleets
The Air Force outlined aggressive production and fielding goals for both the CCA and the new Massed Modular Aircraft (MMA) programs. The service intends to purchase a total of 1,000 combat-ready, semi-autonomous CCA systems.
During his keynote address, Meink detailed the timeline for integrating these platforms into the operational fleet. He noted that the service plans to have at least 500 of the CCA platforms in service by 2032.
“They’ll be performing many of the same missions that we do with manned fighters today,” Meink said, according to DefenseScoop.
The MMA program, designed to field a family of low-cost, multi-role strike platforms to succeed the General Atomics MQ-9 Reaper, is also being accelerated alongside the CCA initiative.
Reporting by The War Zone highlighted Meink’s comments on the MMA timeline. The Secretary stated the intent is to field 100 MMAs in 2029 at a lower cost than the CCAs and a fraction of the cost of current crewed aircraft. He added that 500 of the MMA platforms are expected to join the force by 2032.
AirPro News analysis
The formal naming of the FQ-42A Vengeance and FQ-44A Fury, coupled with the aggressive 2029 and 2032 procurement targets, underscores a fundamental shift in U.S. Air Force force structure planning. We observe that the rapid transition from prototyping to production contracts in June 2026, followed by this public cementing of the fleet’s nomenclature, indicates the Department of Defense (DoD) is prioritizing autonomous mass over traditional, lengthy crewed fighter development cycles. The simultaneous acceleration of the MMA program to replace the MQ-9 Reaper, suggests a comprehensive overhaul of the uncrewed tactical fleet is underway, aiming to overwhelm potential adversaries with affordable, attritable capacity.
