Lockheed Martin has been awarded a $7 billion contract for comprehensive F-22 Raptor stealth fighter air vehicle sustainment, the U.S. Department of Defense said in a press release.

“Lockheed Martin Aeronautics Co., Fort Worth, Texas, has been awarded an indefinite-delivery/indefinite-quantity contract with a total estimated value of $7,000,000,000 for F-22 sustainment,” the release said on Thursday, December 21. “This contract provides for comprehensive F-22 air vehicle sustainment.”

The sole-source contract has a five-year base ordering period with work expected to be completed by December 31, 2027.

Work will be performed at five operational bases: Joint Base Elmendorf-Richardson, Alaska; Nellis Air Force Base, Nevada; Tyndall Air Force Base, Florida; Joint Base Langley-Eustis, Virginia; and Joint Base Pearl Harbor-Hickam, Hawaii; as well as at six support locations. Work may also be performed at other U.S. and overseas locations including combat deployment and enroute support bases, the release said.

The announcement comes less than a week after Pratt & Whitney was awarded a $6.7 billion eight-year contract for F-22 engine sustainment.
