US Air Force Awards Kongsberg $241 Million Contract for Second Production Lot of AGM-184 Joint Strike Missiles

Technical Summary

The Air Force Life Cycle Management Center at Eglin Air Force Base, Florida, awarded Kongsberg Defence and Aerospace AS a firm-fixed-price contract valued at 241 million US dollars on 5 June 2026 for Lot 2 production of the AGM-184 Joint Strike Missile (JSM). The award covers complete ready-to-fire rounds together with containers, test hardware and associated support and diagnostic equipment. The quantity of missiles was not disclosed. Work will be performed at Kongsberg facilities in Norway, completion is expected by 30 November 2028, and the full contract value was funded at the time of award.

The AGM-184 is the air-launched derivative of the Kongsberg Naval Strike Missile family: a low-observable cruise missile roughly 4.0 m long and around 416 kg, powered by a Williams International F-415 turbofan to a high-subsonic cruise of about Mach 0.9. Its guidance suite combines inertial navigation with GPS updates and terrain-reference navigation for the low-altitude mid-course, then a passive imaging infrared terminal seeker with automatic target recognition; open sources also credit a passive radio-frequency homing mode against radar-emitting threats and a two-way, Link 16 compatible datalink for in-flight re-targeting and bomb-hit indication. The warhead is an approximately 120 to 125 kg class blast-fragmentation type with insensitive high explosive fill and a programmable, void-sensing fuze; Janes assesses a blast yield on the order of 100 kg TNT equivalent, although the precise explosive fill mass is not published. Open sources credit the weapon with a range exceeding 275 km in low-altitude profiles and beyond 500 km in higher cruise profiles. The missile was dimensioned from the outset for internal carriage in the F-35A weapons bay, where two rounds are carried internally and a further four can be carried externally, and it is currently described in open sources as the only weapon of its class with that internal-carriage capability.

Lot 2 rounds are destined for US Air Force storage facilities, with production in Norway complete by 30 November 2028 and the full 241 million dollars funded at award. US Department of War contract announcement, 5 June 2026

Analysis of Effects

The second production lot consolidates the US Air Force's commitment to an internally carried standoff missile sourced from a European ally. Internal carriage preserves the F-35A's low-observable configuration to the release point, which matters most in the opening phase of a campaign while integrated air defences remain intact. The JSM's passive infrared terminal seeker emits no radio-frequency signature, complicating detection and electronic attack compared with active-radar seekers, and supports automatic target recognition against ships and discrete land targets.

The customer base now spans Norway, the United States, Japan, Australia and Germany, with Belgium and Poland reported as interested. Germany signed an approximately 300 million euro follow-on JSM contract in May 2026. Kongsberg is expanding production accordingly, with additional missile production capacity in Norway and a new missile factory in Australia working towards a 2027 opening. The undisclosed Lot 2 quantity prevents unit-cost calculation, although full funding at award signals procurement urgency rather than incremental budgeting.

Personnel and Safety Considerations

For ammunition storage and handling organisations the JSM all-up round presents a composite hazard: an insensitive high explosive warhead, turbojet fuel load, pyrotechnic cartridges and batteries packaged in a single container. The contract announcement does not state the UN hazard classification of the packaged configuration. Hazard Division, Compatibility Group and Net Explosive Quantity (NEQ) per container govern storage siting, mixing and transport at receiving US Air Force storage facilities under DESR 6055.09 (Defense Explosives Safety Regulation) and, for NATO-shared sites, Allied Ammunition Storage and Transport Publication 1 (AASTP-1) Edition C criteria.

Data Gaps

Missile quantity in Lot 2: not disclosed. Unit cost: cannot be derived. Precise explosive fill mass and declared net explosive quantity: not published (open sources cite a blast yield on the order of 100 kg TNT equivalent, which is an effect estimate rather than a declared NEQ). Hazard Division and Compatibility Group of the packaged round: not stated. Delivery destinations beyond the generic description of US Air Force storage facilities: not disclosed. Lot 1 quantity and value for comparison: not restated in the announcement.
