Pratt & Whitney received a $762.5 million modification to a previously awarded fixed-price incentive fee contract for F-35 fighter engines on Nov. 22.
The modification funds 48 F135-100 engines for Air Force F-35A aircraft, and 10 F135-600 engines for Marine Corps F-35B aircraft.
The Air Force work is worth $521.5 million and the Marine powerplants represent $241 million of the award; together they fund US engines in the F-35 Lot 14 production.
All the funds are obligated immediately and none expire at the end of the fiscal year.
About 85 percent of the work will be done at Pratt’s East Hartford, Conn., facilities, with the rest at its Indianapolis, Ind. plant (11.8 percent) and Bristol, UK (2.9 percent).
The work is to be completed in April 2022.
