The US Air Force has ordered JSMs from Kongsberg Defence & Aerospace under a US$141 million under a Undefinitised Contract Action (UCA) announced on 3 June.
The missile, a joint development by Raytheon and Kongsberg, has been designed for internal carriage on Lockheed Martin F-35A multirole aircraft.
Japan and Norway have already signed contracts for JSMs and full-operational capability is expected in 2025 with integration onto the latter’s F-35s. Missile deliveries for USAF will be expected to start in 2026.
Shephard Defence Insight noted that the JSM was designed to attack land and sea targets. It has a 230kg HE blast-fragmentation warhead and a range of 185–555km depending on the profile, with inertial, GPS and terrain-reference navigation systems. The missiles come with imaging, infrared homing and a target database.
Japan selected the JSM in 2017 and, on 1 December 2020, Kongsberg announced that it was awarded a second follow-on contract valued at NOK820 million (US$78 million) with Japan buying the JSM for their fleet of F-35 fighter aircraft.
In October 2021 Kongsberg announced that it would arm the Royal Norwegian Air Force fleet of F-35As with JSM under a NOK3.9 billion contract.
In 2023, Australia’s Strategic Defence Review noted that JSM would also be integrated onto the Royal Australian Air Force F-35A, with aircraft to be upgraded to Block 4 configuration.
