1F-35 low-rate initial production Lot 12
The F-35 is a Joint Strike Fighter operated jointly by the Air Force, Navy, and Marine Corps, and its procurement is centrally managed by the Navy-based Joint Program Office (JPO).
2What LRIP means
LRIP (Low-Rate Initial Production) is the ramp-up stage before full-rate production, during which a small number are built while manufacturing processes and quality are stabilized. An advance acquisition contract is a framework to fund long-lead items for a specific production lot (here, Lot 12) ahead of the main production contract.
3Why the F-35 sits at the center of procurement
Alongside the separately compiled F-35 long-lead material contracts, this award again shows that the F-35 is an outsized multi-year, multinational program within U.S. defense procurement.
4Where $35.1 billion sits
Sorting the 207 Department of Defense contracts this site holds as of 2026-09-01 by amount puts this one second. Among procurements of equipment it is the largest.
The F-35 is the joint strike fighter operated by the Air Force, Navy and Marine Corps, with procurement managed centrally by the Joint Program Office placed within the Navy. An advance acquisition contract secures, ahead of the main production award, the long-lead parts for a particular production lot — here the twelfth.
The outlay ratio running above the 1.0 percent across all 207 shows material actually being secured, though the outlay column can be incompletely recorded.
Why it matters
A read on the scale and buyers of the production stage of the F-35, a multi-year, multinational program. Useful for aerospace/defense supply chains and readers tracking the U.S. government market and security trends.
