Lockheed Martin has been awarded a fixed-price-incentive firm target modification contract to a previously awarded advance acquisition contract to provide F-35 Conventional Take-Off and Landing (CTOL) aircraft for the US Air Force (USAF).
The Low Rate Initial Production Lot V contract is valued at $4bn, of which the company has received $2.6bn for 21 USAF F-35 Joint Strike Fighter (JSF) aircraft.
The new contract follows after the USAF cut three F-35 jets from the total original order of 34 jets in a move to help fund cost overruns associated with retrofits on the first three orders after the Senate Armed Services Committee denied $264m in funding.
The stealthy, supersonic multirole F-35 Lightning II joint strike fighter (JSF) is equipped with an electro-optical targeting system (EOTS) that provides long-range detection and precision targeting.
The F-35 is equipped with advanced efficient, higher-capacity avionics and is designed to replace the A-10, the AV-8 Harrier, the F-16 and the F/A-18 Super Hornet.
The contract also includes the provision of six Carrier Variant (CV) F-35 aircraft to the US Navy and three Short Take-Off and Vertical Landing (STOVL) F-35 aircraft to the US Marine Corps.
