The U.S. Navy has awarded Lockheed Martin a $7.6 billion contract modification to produce 129 batches of 15 F-35 fifth-generation fighters in all variants.

The contract includes 49 F-35A aircraft (conventional takeoff) for the U.S. Air Force, three F-35B aircraft (short takeoff and vertical landing), and 10 F-35C aircraft (carrier variant) for the Marine Corps.

Also included are 15 F-35Cs for the U.S. Navy, 32 F-35As and four F-35Bs for non-US Department of Defense participants, and 16 F-35As for foreign customers.

The Pentagon’s contract announcement says that work on this modification is expected to be completed in October 2024.

Separately, the D.O.D. awarded Lockheed Martin a $53.4 million modification to “conduct engineering and other associated tasks” for an unspecified foreign military sales (FMS) customer.

The Pentagon was vague about the buyer, but it’s worth noting that Israel is working on a unique F-35 model that will allow the Israeli Air Force to use only Israeli-developed components.

Israel received the first of these unique airframes in 2020. According to Lockheed Martin’s latest fact sheet on the F-35 program, the company has delivered more than 825 airframes to nine countries. The world fleet has accumulated more than 550,000 flight hours with more than 323,000 sorties.
