US Air Force Validates Open Architecture for Collaborative Combat Aircraft
The US Air Force validates A-GRA, enabling autonomy software from multiple vendors to operate on different aircraft for the Collaborative Combat Aircraft program.

This article is based on an official press release from the U.S. Air Force.
Air Force Validates Open Architecture for Collaborative Combat Aircraft
The United States Air Force has successfully validated a key technical pillar of its Collaborative Combat Aircraft (CCA) program, proving that mission autonomy software can operate seamlessly across different aircraft hulls. According to an official announcement released Thursday, the service has implemented the government-owned Autonomy Government Reference Architecture (A-GRA) on platforms from multiple vendors, a move designed to eliminate proprietary “vendor lock” and accelerate technology fielding.
The validation effort involved integrating third-party autonomy software onto the program’s two primary prototype airframes: the YFQ-42A from General Atomics and the YFQ-44A from Anduril Industries. By decoupling mission software from vehicle hardware, the Air Force aims to create a competitive “ecosystem” where the best available technology can be rapidly deployed to the warfighter regardless of which company built the aircraft.
Breaking Vendor Lock with A-GRA
The core of this recent success is the Autonomy Government Reference Architecture (A-GRA). In the past, military aircraft often relied on proprietary software systems tightly coupled with the hardware, making upgrades difficult and expensive. The A-GRA model establishes a universal standard, allowing the Air Force to swap software modules, such as targeting algorithms or flight behaviors, without redesigning the entire aircraft.
Col. Timothy Helfrich, the Air Force’s Portfolio Acquisition Executive for Fighters and Advanced Aircraft, emphasized the strategic importance of this validation in the press release.
“Verifying A-GRA across multiple partners is critical to our strategy. It proves that we are not locked into a single solution or a single vendor.”
Col. Timothy Helfrich, U.S. Air Force
Helfrich added that the service is building a competitive environment where algorithms can be deployed on any compliant platform. This approach aligns with the Department of Defense’s broader push for “open mission systems,” ensuring that future upgrades can be sourced from a diverse range of traditional defense contractors and non-traditional software firms.
Flight Testing and Industry Partners
The Air Force announcement detailed specific pairings of autonomy providers and airframe manufacturers used during the validation process. The service stated that mission autonomy vendors RTX Collins and Shield AI have begun semi-autonomous flight testing. These software providers were paired with the program’s hardware primes:
- RTX Collins software integrated with the General Atomics YFQ-42 platform.
- Shield AI software integrated with the Anduril Industries YFQ-44 platform.
This cross-pollination of vendors demonstrates the program’s modularity. According to the Air Force, the Agile Development Office director noted that integrating A-GRA onto multiple platforms quickly demonstrates that the open-system approach works, allowing the service to “iterate tactics and capabilities across the fleet at a pace that keeps us ahead of the threat.”
AirPro News analysis
The successful validation of A-GRA represents a significant shift in how the Pentagon buys tactical aircraft. Historically, the prime contractor for an aircraft (such as Lockheed Martin for the F-35) controlled the entire software ecosystem, often leading to high sustainment costs and slow upgrade cycles. By enforcing a government-owned reference architecture, the Air Force is effectively commoditizing the airframe while placing higher value on the software “brains” of the CCA fleet.
This structure also lowers the barrier to entry for software-focused defense tech companies. Firms like Shield AI and RTX Collins can compete solely on the performance of their autonomy code without needing to build physical aircraft. For the CCA program, which aims to field at least 1,000 affordable, autonomous drones to fly alongside the F-35 and Next Generation Air Dominance (NGAD) fighters, this modularity is essential to keeping costs down and adaptability high.
Frequently Asked Questions

Bell Boeing Awarded $157M Contract to Upgrade V-22 Osprey Fleet
The DoD awarded Bell Boeing a $157 million contract for structural upgrades to the V-22 Osprey, focusing on nacelles and pylons with completion by 2028.

This article summarizes reporting by Defence Blog and additional defense research.
The U.S. Department of Defense has awarded a sole-source contract worth up to $157 million to the Bell Boeing Joint Program Office for critical upgrades to the V-22 Osprey fleet. Announced on April 10, 2026, the contract focuses on structural and mechanical improvements to the MV-22 and CMV-22 variants utilized by the U.S. Navy and Marine Corps.
According to reporting by Defence Blog, the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland, is managing the initiative. The upgrades specifically target the aircraft’s nacelles and pylon assemblies, which have historically been the most maintenance-intensive components of the tiltrotor aircraft.
This financial investment underscores the military’s ongoing commitment to extending the service life, safety, and operational readiness of the Osprey. Currently, the V-22 platform has no direct replacement in production, making sustainment efforts a high priority for the Pentagon.
Contract Details and Deliverables
The $157 million agreement provides stable near-term financing for the Bell Boeing joint venture. Defense research data indicates that at the time of the award, $60.67 million in Fiscal Year 2025 Navy aircraft procurement funds and $16.25 million in FY 2026 funds were obligated. None of these funds will expire at the end of the current fiscal year.
Deliverables under this contract include 10 Nacelle Improvement Kits and three shipsets of Pylon Support Assemblies. The estimated completion date for this manufacturing and upgrade work is December 2028. The order was not competitively bid, reflecting the proprietary, sole-source nature of V-22 production and sustainment under the Bell Boeing joint program.
Production Distribution
The manufacturing work will be distributed across three primary facilities in two states. According to defense research reports, the vast majority of the production, 84 percent, will take place in Amarillo, Texas. An additional 15 percent will be handled in Fort Worth, Texas, while the remaining 1 percent is allocated to Ridley Park, Pennsylvania.
Technical Focus: Nacelles and Pylons
The V-22 Osprey’s unique capability to take off vertically like a helicopter and fly forward like a turboprop relies heavily on its nacelles. These engine housings, mounted at each wingtip, rotate through a 90-degree arc during flight transitions.
However, the rotating mechanisms and internal drive systems within these nacelles have proven to be highly demanding from a maintenance perspective. The newly funded upgrades aim to reduce mechanical issues and improve overall fleet reliability to sustain the high operational tempo required by the U.S. military.
Pylon Support Assemblies
In addition to the nacelles, the contract funds upgrades to the pylon support assemblies. These critical structures connect the nacelles to the wings and are responsible for absorbing immense operational loads and structural stress during flight.
Strategic Context and Safety Overhauls
The Osprey remains an indispensable asset for U.S. forces. The Marine Corps relies on the MV-22 for its “distributed maritime operations” concept, utilizing the aircraft’s long-range speed and vertical lift across the vast distances of the Indo-Pacific theater. Meanwhile, the Navy’s CMV-22B variant recently began replacing the aging C-2A Greyhound for Carrier Onboard Delivery (COD) missions, transporting personnel and priority cargo to aircraft carriers at sea.
Despite its unique capabilities, the V-22 program has faced significant public and congressional scrutiny following a series of mechanical issues and fatal mishaps. Readiness rates for the aircraft have historically hovered below 60 percent.
Broader Modernization Efforts
This $157 million contract is part of a wider, multi-year Department of Defense effort to address the Osprey’s mechanical vulnerabilities and ensure the long-term safety of service members.
“The upgrades focus on the most mechanically demanding elements of the Osprey’s unique tiltrotor design,” according to defense research reports.
Notably, the Osprey fleet has been operating under restricted flight profiles since April 2025. As noted in recent defense reports, this restriction accommodates a separate, highly critical upgrade to the proprotor gearbox, which incorporates triple-melted steel components to remove metal impurities and enhance safety.
AirPro News analysis
We observe that the Pentagon is increasingly forced to balance the high costs of sustaining aging, complex platforms against the delayed fielding of next-generation alternatives. Because the Bell V-280 Valor remains in development for the Army and is not yet ready for Navy or Marine Corps integration, the military has no choice but to heavily invest in the V-22’s mechanical longevity.
Furthermore, the concentration of manufacturing work in Texas highlights the localized economic impact of the defense industrial base. By funneling 99 percent of this contract’s production into Amarillo and Fort Worth through 2028, the DoD is simultaneously reinforcing domestic aerospace manufacturing capabilities while attempting to rectify the Osprey’s long-standing readiness shortfalls.
