The Navy on Thursday awarded a pair of F-35 contracts worth nearly a combined $2 billion, according to a Defense Department statement.

The Navy awarded Pratt & Whitney a $1.5 billion firm-fixed-price, incentive-firm target modification for components, parts and materials for low rate initial production (LRIP) Lot 10 of F135-PW-100 propulsion systems. The contract includes 44 engines for the Air Force, four for the Navy and nine F135-PW-600 propulsion systems for the Marine Corps.

In addition, the contract modification provides components, parts and materials for 36 F135-PW-600 propulsion systems for international partners and two F135-PW-100 propulsion systems for the global spares pool. Work is expected to be completed by September 2019.

The Navy also awarded a $560 million cost-plus-incentive-fee, fixed-price-incentive-firm contract for non-air vehicle spares, support equipment, autonomic logistics information system hardware and software upgrades, supply chain management, full mission simulators and non-recurring engineering services. These are in support of LRIP Lot 10 F-35 aircraft for the Air Force, Marine Corps, Navy, non DoD participants and foreign military sale (FMS) customers.
