The Navy awarded two contracts for Navy aircraft worth hundreds of millions of dollars each on Thursday for the F-35 and P-8A aircraft.

The Naval Air Systems Command (NAVAIR) awarded Lockheed Martin [LMT] a $558 million contract for the sustainment support, including equipment, training devices, training facilities, non-aircraft spares, various hardware and software, and facilities support for low-rate initial production (LRIP) Lot 11 F-35 aircraft.

The work covers F-35s bound for the Navy, Marine Corps, Air Force, non-Defense Department participants, and foreign military sales (FMS) customers.

The contract work will largely be performed in Orlando, Fla., and Redondo Beach, Calif., and is expected to be finished by February 2023. The full contract value is obligated at award time, with $19.5 million expiring at the end of the current fiscal year.

The award is split into $232 million/42 percent non-DoD participants, $173 million/31 percent for the Air Force, $62 million/11 percent Marine Corps, $51 million/nine percent Navy, and $40 million/seven percent FMS customers.
