The U.S. Air Force awarded Norwegian defense manufacturer Kongsberg Defence & Aerospace a firm-fixed-price contract valued at $240,904,098 on June 5, 2026, for Lot 2 production of the Joint Strike Missile (JSM), according to the Department of Defense contracts announcement. The award, designated contract number FA8681-26-C-B002, was issued by the Air Force Life Cycle Management Center at Eglin Air Force Base, Florida, and carries a period of performance running through November 30, 2028.
What the Joint Strike Missile Is
The Joint Strike Missile is a precision standoff weapon developed by Kongsberg Defence & Aerospace — the same Norwegian company behind the Naval Strike Missile — and is purpose-built to operate against both land and maritime targets at extended range. What distinguishes the JSM from comparable weapons is its physical design: the missile was engineered from the outset to fit within the F-35A's internal weapons bay, allowing the aircraft to carry it without sacrificing its low-observable, stealth profile. External carriage of weapons significantly increases an aircraft's radar cross-section; internal carriage eliminates that penalty and preserves the F-35's core survivability advantage.
The Lot 2 contract scope is described in the DoD announcement as covering "the purchase of all up rounds with containers, test hardware, and support items" — meaning complete, ready-to-ship missile assemblies packaged with associated ground support equipment and test articles, not just missile bodies. Integration is currently fielded on the F-35A conventional takeoff-and-landing variant. Work on integration for the F-35B short-takeoff/vertical-landing and F-35C carrier variant is planned but not yet complete, making this contract specifically tied to the F-35A program at this stage.
Sole-Source Rationale
The contract was awarded on a sole-source basis, meaning the Air Force did not conduct a competitive procurement process. Sole-source awards under FAR Part 6 are permissible under specific statutory exceptions, most commonly when only one responsible source is available and no other supplies or services will satisfy agency requirements. In this case, Kongsberg is the sole designer, developer, and manufacturer of the JSM. No domestic or allied competitor produces a weapon with equivalent form, fit, and function for the F-35A's internal bay — a fact that reflects both the missile's specialized geometry and the extensive F-35 integration work already completed and certified by Kongsberg.
Sole-source procurement at this scale — nearly a quarter-billion dollars — is not unusual for mature weapon system production follow-ons where the OEM holds exclusive technical data rights and the government has already invested in qualification testing. The Air Force's decision to proceed without competition signals confidence in Kongsberg's performance on Lot 1 and the absence of a viable alternative supplier within the required delivery window.
Funding Structure
The $240.9 million obligation is split across two fiscal years of missile procurement appropriations. The Air Force committed $137,970,866 in FY2024 missile procurement funds and $102,933,232 in FY2025 missile procurement funds at the time of award. The use of multi-year procurement dollars — specifically funds from a prior fiscal year (FY24) obligated alongside current-year (FY25) funds — is a standard mechanism for large, multi-year weapon buys where program planning precedes contract execution. Both tranches are classified as missile procurement funds, a distinct budget line from research and development or operations and maintenance accounts, confirming this is a production — not a development or sustainment — contract.
For context, the preceding Lot 1 award in 2024 has been reported at approximately $141 million. Lot 2 at $240.9 million represents a substantial increase in contract value, consistent with a larger production quantity and the cost structures associated with scaling missile manufacturing beyond initial low-rate production volumes.
Production Implications
A period of performance extending to November 30, 2028, places Lot 2 deliveries well within the current F-35A operational deployment cycle. The JSM provides the F-35A with a capability it has lacked against surface targets at standoff range without breaking stealth — a gap that has drawn increasing attention as near-peer adversaries have expanded integrated air defense coverage. Fielding a larger inventory of JSMs directly addresses that gap for Air Force F-35A squadrons.
The planned but not yet completed integration work for the F-35B and F-35C variants also carries procurement significance. If and when those integrations are certified, additional lot awards for Navy and Marine Corps variants would follow through the respective service program offices, potentially expanding the JSM's U.S. procurement base beyond the Air Force.
What It Means for Contractors
For defense contractors and subcontractors operating in the precision munitions and F-35 supply chain, this award carries several practical implications worth tracking.
Tier 2 and Tier 3 opportunities: Kongsberg is a foreign prime, but JSM production draws on U.S.-sourced components, materials, and potentially domestic subcontractors for specific subsystems. U.S. firms already embedded in Kongsberg's supply chain for Lot 1 should expect continued or expanded orders. Companies not yet in that supply chain should monitor Kongsberg's U.S. procurement activity and contracting notices through SAM.gov.
Sustainment and logistics follow-on: All-up-round production contracts of this type are typically accompanied by separate sustainment, spares, and depot-level maintenance contracts as the missile inventory matures. The period of performance through late 2028 means sustainment solicitations for the growing JSM fleet could appear in the FY2027–FY2029 timeframe. Contractors with logistics, packaging, handling, and storage expertise relevant to air-launched munitions should watch for related solicitations from AFLCMC at Eglin AFB.
F-35B/C integration work: Integration of the JSM onto the F-35B and F-35C remains an open program item. Contractors supporting F-35 weapons integration, flight test, or software development may find relevant opportunities as that work matures and moves toward contract action.
Contracting office: All activity on this program runs through the Air Force Life Cycle Management Center at Eglin AFB, Florida. Contracting professionals tracking JSM-related opportunities should register the AFLCMC contracting office as a primary watch point on SAM.gov and beta.SAM.gov for future solicitations directly tied to this weapon system.
