Power, innovation and dependability are at the core of the F135, which powers all three variants of the F-35 Lightning II fighter aircrafT
defined by capability
The F135’s 5th Generation propulsion capabilities provide the
warfighters of today and tomorrow the technological edge to fight and win.
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.
DRIVEN BY INNOVATION
A History of Innovation
For nearly a century, we’ve been advancing military propulsion for tactical, strategic, and mobility aircraft. From the development of our iconic Wasp engine in the 1920’s to the game-changing technology of today’s F135, our innovation is driven by our commitment to provide customers the most advanced, dependable products to complete their mission and return home safely.
Combat Proven Propulsion
Evolved from the proven F119 engine that powers the F-22 Raptor, and building upon decades of combat-proven propulsion experience, the F135 is a marvel of modern engineering – from design and development, to production and sustainment. From its adaptive and maintenance-friendly design to the use of exotic materials and advanced manufacturing processes, the F135 is the pinnacle of combat propulsion.
Bringing the Future, Faster
The F135 also stands as a prime example of our commitment to the continuous improvement of our products. Conceived with the knowledge that operational environments will evolve and threats will advance, the F135’s modular design and digital architecture support agile upgrades. Our F135 Enhanced Engine Packages (EEP) incorporate next-generation adaptive propulsion technologies that offer increased thrust and fuel efficiency, as well as power and thermal management system capacity to keep the F-35 weapon system a step ahead.
Delivering Superior VALUE
The F135 engine delivers unparalleled value for the taxpayer, providing a
generational leap in performance and reliability at a relatively small
incremental cost over 4th generation engines given its world-class
design attributes, high tech components, and 5th Generation enabling
The operational value of the F135 is defined by its:
The F135 truly separates itself from 4th generation engines with a range of 5th Generation engine attributes that include substantially increased power and thermal management, engine-flight control integration, and signature management. The capabilities of the F135 provide the warfighter with a critical advantage over adversaries and enables the F-35 to conduct operations in advanced anti-access/area denial (A2/AD) environments, a core element of the National Defense Strategy
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.
The F135 was designed for ease of maintenance and affordable sustainment. The F135’s tri-variant commonality, advanced digital health management system, and global sustainment
structure – including a shared parts pool & regionalized MRO&U network
– provides fleet operators ease of maintenance at reduced operating costs.
Leveraging significant U.S. Government and P&W investment in next generation adaptive propulsion technologies, P&W has developed F135 Enhanced Engine Packages (EEP) which offer increased thrust, fuel efficiency, as well as power and thermal management system capacity. The EEPs are affordable, variant-common, low risk upgrades that can be available to meet warfighter needs in Block 4 and beyond aircraft to ensure the F-35 remains ahead of evolving threats.
We’re committed to the effective stewardship of taxpayer resources and continue to work tirelessly to drive down costs across the program. Having reduced the average production cost of an F135 engine by more than 50%, we are now targeting a 50% reduction in cost per flight hour to bring sustainment costs down to the same level as 4th generation fighter engines. We are doing this through component improvements such as life extensions and limits expansion; new repair processes; spare part cost reduction; and digital technologies.
