Lockheed Martin has secured a $12.53 billion contract modification from the U.S. Navy to produce and deliver F-35 aircraft units for the Air Force, Marine Corps, Navy, international partners and foreign military sales customers.
The award covers the definitization of 148 Lot 18 aircraft and expands the scope for the production and delivery of 148 Lot 19 units, the Department of Defense said Monday. Aircraft deliveries under the agreement will include 40 F-35As for the Air Force, 12 F-35Bs and eight F-35Cs for the Marine Corps, nine F-35Cs for the Navy, 13 F-35As and two F-35Bs for cooperative program partners, and 52 F-35As and 12 F-35Bs for FMS customers.
Work will be performed in Texas, California, Maryland, New Hampshire and Florida in the United States, various locations outside the continental U.S., and in the United Kingdom, Japan and Italy through August 2028. Funding sources include the Air Force and Navy’s fiscal 2025 aircraft procurement funds, cooperative program partner funds and FMS customer funds. Naval Air Systems Command in Patuxent River, Maryland, is the contracting activity.
Prior F-35 Awards
The modification follows earlier F-35 production awards. In December 2022, Lockheed received a $1.05 billion contract to provide materials and services for 118 Lot 18 aircraft, benefiting U.S. services, allies and FMS customers.
In January 2023, Lockheed and the Department of Defense finalized a $30 billion deal covering F-35 Lots 15 through 17. The contract included up to 398 jets for U.S. and international customers and the Technical Refresh-3 hardware upgrade featuring an integrated core processor, expanded memory and a panoramic cockpit display.
