Pratt Whitney F119 Engine Surpasses One Million Flight Hours
Pratt & Whitney’s F119 engine fleet hits 1 million flight hours, backed by a $1.5B USAF sustainment contract for the F-22 Raptor.

Pratt & Whitney announced on June 30, 2026, that its F119 engine fleet has surpassed one million cumulative flight hours, marking a major operational milestone for the propulsion system that powers the United States Air Force Lockheed Martin F-22 Raptor.
The milestone, announced from the manufacturers East Hartford, Connecticut headquarters, underscores the long-term viability of the world’s first fifth-generation fighter engine. With the final production F119 delivered in 2013, the focus has shifted entirely to sustainment and modernization to keep the F-22 fleet combat-ready.
Sustainment and fleet readiness
The achievement follows a major sustainment agreement secured on February 20, 2025, when Pratt & Whitney, an RTX business, was awarded a three-year contract valued at up to $1.5 billion to support the F119 fleet. The contract covers maintenance and modernization for more than 400 engines currently in service.
To maintain the engines decades after production ceased, Pratt & Whitney utilizes Model-Based Systems Engineering and a Usage-Based Lifing program. These initiatives are designed to lower lifecycle costs, improve readiness rates, and implement engine control schedule updates, ensuring the F-22 remains operationally viable for the United States Air-Forces (USAF).
Technological legacy and operational history
The F-22 Raptor entered operational service with the USAF on May 12, 2005. Each aircraft is powered by two F119 engines, which feature a unique thrust-vectoring nozzle. This design enables supercruise, allowing the aircraft to sustain supersonic speeds without engaging afterburners.
The technological foundation established by the F119 directly informed the development of the Pratt & Whitney F135 engine, which currently powers the Lockheed Martin F-35 Lightning II.
“Having powered the F-22 Raptor since it launched over 20 years ago, the engine continues to provide unmatched capability, safety and readiness rates,” said Jill Albertelli, President of Military Engines for Pratt & Whitney. “This milestone demonstrates Pratt & Whitney’s commitment to delivering for our customers.”
AirPro News analysis
Reaching one million flight hours on a closed-production engine line highlights the critical role of predictive maintenance and usage-based lifing in modern military aviation. Because the USAF cannot simply procure new F119 engines to replace aging units, the $1.5 billion sustainment contract awarded in 2025 is essential for maintaining the air superiority mission of the F-22.
We view the continued investment in F119 modernization as a clear indicator that the F-22 will remain a cornerstone of USAF operations well into the next decade, even as next-generation air dominance platforms are developed and fielded.

Airbus and Alta Ares Partner on AI Counter-Drone Integration
Airbus Defence and Space and Alta Ares signed an MOU to integrate AI-guided interceptors into Airbus air defense command systems.

Airbus Defence and Space and European defense technology company Alta Ares signed a memorandum of understanding on June 11, 2026, to integrate artificial intelligence-guided counter-drone interceptors into Airbus air defense command systems.
Announced during the ILA Berlin Air Show, the partnership aims to create a unified sensor-to-shooter chain capable of neutralizing mass-deployed, one-way attack drones. According to a press release issued by Airbus, the agreement will link Alta Ares interceptor hardware and targeting software directly into existing Airbus battle management networks.
Integration of AI and interceptor hardware
The technical integration focuses on connecting Alta Ares systems with Airbus command software. Alta Ares will integrate its Pixel Lock artificial intelligence platform, along with its Black Bird medium-range and X-Lock short-range interceptors, into the Airbus Fortion Integrated Battle Management Software (IBMS) and the Fortion Surface-to-Air Missile Operation Centre (SAMOC).
Alta Ares Co-Founder and Chief Executive Officer Hadrien Canter stated that modern air defense requires both software and hardware operating simultaneously at scale.
“Integrating Pixel Lock and our interceptors into Fortion IBMS means operators get a single, coherent sensor to shooter chain from detection to neutralisation. That’s what theatre commanders are actually asking for,” Canter said.
François Lombard, Head of Connected Intelligence at Airbus Defence and Space, noted that defending against suicide drones is an urgent priority in current asymmetric conflict environments. He emphasized the need for cost-efficient solutions that fit within the broader air defense ecosystem to protect European airspace and allied forces.
Airbus expands counter-UAV portfolio
The Alta Ares agreement follows a series of rapid expansions in the Airbus counter-Uncrewed Aerial Systems (C-UAS) portfolio through collaborations with specialized defense startups. The prime contractor has utilized the ILA Berlin event to solidify multiple integration partnerships.
On June 10, 2026, Airbus Helicopters signed a cooperation agreement with German drone manufacturer Quantum Systems. That partnership will explore integrating C-UAS interceptors onto military helicopters, beginning with the multi-role H145M platform.
Earlier in the year, on March 30, 2026, Airbus demonstrated its own Bird of Prey interceptor drone. During that test, the autonomous system engaged a target using a Mark I missile developed by Estonian startup Frankenburg Technologies.
Alta Ares scales production
Founded in 2024, Alta Ares specializes in counter-drone systems and on-board artificial intelligence. The company saw its systems first operationally deployed in Ukraine during 2024 and has since expanded to meet military demand for defenses against autonomous drones.
On June 9, 2026, two days prior to the Airbus announcement, Alta Ares secured €50 million in a Series A funding round led by Air Street Capital. The company stated the funding will be used to scale the production of its X-Lock and Black Bird interceptor platforms.
AirPro News analysis
The rapid succession of Airbus partnerships at ILA Berlin highlights a strategic shift for the aerospace manufacturer. Rather than developing bespoke interceptor solutions entirely in-house, Airbus is positioning its Fortion software suite as the central nervous system for European air defense while plugging in specialized hardware from agile startups like Alta Ares, Quantum Systems, and Frankenburg Technologies. We view this modular approach as a direct response to the rapid iteration of drone warfare observed in recent conflicts, where traditional surface-to-air missiles are economically unviable against mass-deployed, low-cost autonomous threats. By securing integration rights with well-funded startups, Airbus ensures its command-and-control architecture remains indispensable to European defense ministries.
