Kongsberg touts the missile as “fully passive,” meaning it does not use active sensors to track targets. NSM does not emit infrared or radar waves that could be detected by enemy ships. Weighing in at 410 kilograms, NSM is smaller than other missiles on this list. The missile has a range of 185 kilometers and carries a 125 kilogram warhead.

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.
