Overview
- The Navy ordered $879.1 million in Lot 18–19 armament gear for F-35s, covering launchers, racks, pylons, gun systems, and adapters, with work in Fort Worth set to finish by February 2030.
- Foreign partners will fund a large share of that armament order, with $333.6 million from FMS customers and $139.2 million from non‑U.S. participants obligated at award.
- A separate $991.13 million order will deliver 432 material modification kits that upgrade the jets’ electronic‑warfare system, with completion projected in March 2032.
- The 432 kits are allocated to 97 Air Force, 54 Marine Corps, and 42 Navy aircraft, plus 106 for FMS customers and 133 for other non‑U.S. participants.
- Together these contracts align with rising Lot 18–19 deliveries and broader Block 4 modernization, ensuring newly built and fielded jets have the hardware needed to carry and integrate weapons on arrival.
