NSM is currently in service with the Norwegian Navy’s Skjold-class missile boats and Fritjof Nansen-class destroyers. NSM is also operated by the Polish Army as coastal artillery.

In October 2014, the U.S. Navy tested a Naval Strike Missile from the flight deck of the littoral combat ship USS Coronado. The test was a success, with a direct hit on a simulated target. The test was part of the Navy’s Foreign Competitive Testing Program and does not necessarily mean the Navy will acquire NSM.

A version of the Naval Strike Missile, the Joint Strike Missile, is currently under development. The JSM will be capable of both air to ground and anti-ship missions, and will fit the internal weapons bay of the F-35 Joint Strike Fighter. It will also fit a standard 533mm submarine torpedo tube. JSM is scheduled to become operational in 2023.
