Pratt & Whitney awarded F-35 engine contract

Pratt & Whitney, a Raytheon Technologies business, has been awarded a $5.2 billion contract to support production of the 15th and 16th lots of F135 engines, with an option to award a 17th lot, powering all three variants of the F-35 Lightning II fighter aircraft.

The Lots 15-17 production contract funds production of 278 F135 engines with an option to order up to a total of 518 engines. The contract also includes program management, engineering support, production support, and tooling. The total contract value for lots 15-17, with exercised options, is approximately $8 billion and will fund more than 418 F135 engines with options for the U.S. and international customers.

"This marks a major milestone for the program," said Jen Latka, Pratt & Whitney's vice president for the F135 program. "This contract award enables us to continue delivering critical 5th Generation propulsion capability to the warfighter at a fair and reasonable cost for the taxpayer."

Since program inception, Pratt & Whitney's "war on cost" efforts have reduced the average unit cost of an F135 by more than 50%, contributing to an estimated $8.1 billion in cumulative engine savings throughout the life of the program.

Pratt & Whitney worked aggressively to drive production efficiencies, optimize its supply base, and invest in strategic initiatives – such as the new turbine airfoil facility in Asheville, North Carolina – to reduce cost wherever possible.

Evolved from the F119 engine powering the F-22 Raptor, the F135 offers increased thermal management capacity, a precise and responsive integrated engine control system, and a low observable signature.

The F135 program is a major driver of economic growth around the country, supporting more than 53,000 jobs across 36 states.

As of December 2022, Pratt & Whitney has delivered more than 1,000 F135 production engines.
