"Lockheed Martin has signed an undefinitized contract that establishes the funding for Lot 5 up to the level announced by the DoD today," said Lockheed Martin spokeswoman Laurie Quincy in an email. "The final Lot 5 contract amount will not be known until we have a definitized contract sometime in 2012."
She said in a statement that the award is welcome news for the company and its F-35 suppliers.
"This … will help ensure we continue to meet production schedules outlined by the program," Quincy wrote. "This is an important first step in paving the way for full LRIP 5 production contract negotiations with our government customer."
The fixed-price-incentive contract calls for 21 F-35A conventional take off and landing (CTOL) for the Air Force, three F-35B short-take off and vertical landing (STOVL) aircraft for the Marines, and six F-35C carrier variants for the Navy.
Broken down by service, two-thirds of the value of the contract - $2.65 billion - is for the Air Force; $937 million, or 23 percent, for the Navy; and $426 million, or nearly 11 percent, for the Marine Corps.
The contract also provides for "associated ancillary mission equipment and flight test instrumentation" for the planes, and flight test instrumentation for the United Kingdom.
The contract was awarded through the Naval Air Systems Command.
The next-generation F-35 is a stealthy (radar-evading), supersonic multirole fighter designed to meet the U.S. government's requirements for a new generation of transformational weapons. The single-engine JSF will be manufactured in three versions: a conventional-takeoff-and-landing (CTOL) variant for the U.S. Air Force, an aircraft-carrier version (CV) for the U.S. Navy, and a short-takeoff/vertical landing (STOVL) version for the U.S. Marine Corps.
The cornerstone of the F-35 is affordability, achieved in large part through a very high level of common parts and systems across the three versions of the aircraft.
The F-35 is designed to replace aging fighter inventories, including U.S. Air Force A-10s and F-16s, U.S. Navy F/A-18s, U.S. Marine Corps AV-8B Harriers and F/A-18s, and United Kingdom Harrier GR.7s and Sea Harriers.
