Power, innovation and dependability are at the core of the F135, more than 1,300 of which currently power all three variants of the global F-35 Lightning II fighter aircraft fleet, which recently surpassed one million engine flight hours.
The F135’s 5th Generation propulsion capabilities provide the warfighters of today and tomorrow the technological edge to fight and win.
How the world’s most powerful fighter jet engine is made
Defined by capability
With more than 40,000 lbs. of thrust, unmatched low-observable signature, world-class thermal management, and the most advanced integrated engine control system ever created, the F135 engine is the heartbeat of the F-35.
Not only is the F135 the most powerful and most advanced fighter engine ever produced, it’s also the most dependable – demonstrating a step change in readiness and reliability over 4th generation fighter engines.
The F135 delivers unrivaled performance to the warfighter, enabling operations in the most advanced threat environments and redefining what’s possible for our customers and their missions.

Ready
With its advanced damage tolerant design and fully integrated prognostic health monitoring, the F135 has demonstrated exceptional mission capability rates since its first flight in 2006. The F135 is the most reliable fighter engine we’ve ever built, providing warfighters the assurance that it will be ready to meet mission demands.
Advancing the future
Leveraging significant U.S. Government and P&W investment in next generation propulsion technologies, P&W developed the F135 Engine Core Upgrade (ECU) which offers increased thrust, fuel efficiency, as well as thermal management capacity for all F-35 variants. ECU will enable capability beyond Block 4 for the warfighter and reduce billions in sustainment costs for the taxpayer.
