The Defense Department said Monday the obligated amount of $311.9 million at the time of award is from the three service branches’ fiscal 2016 aircraft procurement funds.
The modification covers the delivery of three F-35A conventional takeoff-and-landing variants for the Air Force, six F-35B short takeoff and landing variants for the Marine Corps and four F-35C carrier variants for the Navy.
The award came after Lockheed received nearly $180 million in contract funds in late March to obtain long-lead-time items that the company will need to build LRIP Lot 11 F-35s.
Lockheed is scheduled to complete work under the contract modification in December 2019.
