Kongsberg Defence & Aerospace AS has entered into a second follow-on contract with Japan to supply Joint Strike Missile (JSM) for their fleet of F-35 fighter aircraft.
“The international F-35 user community is continuing to show great interest in the JSM and KONGSBERG is very proud to have been selected by Japan to provide the JSM for their F-35 fleet. “Our relationship is growing even stronger with this second follow-on contract”, says Eirik Lie, President, Kongsberg Defence & Aerospace AS.
Joint Strike Missile (JSM) is a 5th generation stealth air-to-surface missile that is designed specifically to fit in the internal weapons bay of the F-35A aircraft thus ensuring the aircraft’s low-signature capabilities. The F-35 would be able to carry two JSM missiles in its internal bays, while additional missiles could be carried externally. The JSM has superior performance against well-defended sea- and land targets across long distances.
The missile is a multi-role air-launched variant of Kongsberg’s Naval Strike Missile (NSM). The JSM development started in 2008 and was completed in mid-2018 after a series of successful validation test firings.
According to FlightGlobal, the missile has an estimated range of 150 NM (172 mi; 278 km). The range is dependent on the flight profile and Kongsberg claims that the range is over 100 NM in low-low-low profile and over 300 NM in hi-hi-low flight profiles.
The achievement of initial operational capability (IOC) is expected in 2021 with the release of the F-35’s Block 4 software and the missile is expected to become fully operational in 2025.
