World's most advanced fighter engine continues to deliver
on safety and readiness for global F-35 operators
EAST
HARTFORD, Conn., March 3,
2025 /PRNewswire/ -- Pratt & Whitney, an RTX
(NYSE: RTX) business, announced today that the F135 engine has
surpassed one million engine flight hours powering the F-35
Lightning II. In achieving this milestone, the F135 has established
itself as the safest, most capable and reliable fighter engine,
delivering superior performance and advanced low-observable
technologies for the fifth-generation fighter
"The F135 engine plays a critical role in maintaining global air
superiority for the U.S. and its allies, as it enables the F-35
mission in even the most contested environments," said Jill Albertelli, president of Military Engines
at Pratt & Whitney. "The engine has powered every F-35 since
the fighter's first flight in 2006, providing exceptional safety
and readiness rates. Accomplishing this milestone in under two
decades demonstrates how critical the F-35 remains and highlights
Pratt & Whitney's commitment to our customer and the
warfighter."
Pratt & Whitney's F135 engine delivers a generational leap
in performance and reliability, giving warfighters the assurance
that it will be ready to meet mission demands. It continuously
exceeds full mission capability rate requirements of 94% and offers
operators an exceptional, unmatched safety record. The F135's
safety rate is more than an order of magnitude better than previous
generations of fighter engines when compared across engine life
cycles.
To help maintain mission readiness, the F135 sustainment network
supports several global depot facilities, 36 bases, and 12 ships
internationally. This positions the engine as a key enabler of
Agile Combat Employment, a military operational concept that
utilizes a network of smaller, dispersed locations to increase
survivability while generating combat power. This concept requires
continuous movement, logistics efficiencies, and specialized
maintenance skills – all which Pratt & Whitney can accommodate
by leveraging the F135's internationally dispersed
infrastructure.
As the F-35 is modernized to include the new capabilities needed
to defeat future threats, it will require more performance from the
engine. Pratt & Whitney's Engine Core Upgrade (ECU) leverages
learnings from advanced engine programs, builds upon the F135's
track record of success, and offers the performance needed to stay
ahead of adversaries.
To date, Pratt & Whitney has delivered more than 1,300 F135
production engines to a global enterprise that includes 20 allied
nations around the world. Visit the Pratt & Whitney website to
