LOUISVILLE, Ky., Aug. 18 (UPI) — Launchers for Kongsberg’s Naval Strike Missile are to be built in the United States by Raytheon.

The initial contract to produce the launchers ushers in U.S. manufacturing of the Norwegian-developed weapon system.

“Building NSM launchers at our Louisville (Kentucky) facility is an excellent extension of our long-standing relationship with Kongsberg,” said Dr. Taylor W. Lawrence, Raytheon Missile Systems president. “This contract will enable us to add jobs while providing our Norwegian teammates with world-class launchers.”

Kongsberg’s NSM has a range of more than 100 nautical miles and is for use against land and sea targets. Raytheon and Kongsberg believe NSM is an ideal solution for use on U.S. Navy Littoral Combat Ship, on which the missile has been tested.

The award from Kongsberg follows a July announcement that Raytheon will produce NSM launchers in the United States. The company also plans to perform final assembly, integration and test of the Naval Strike Missile at Raytheon’s Tucson, Ariz., facility.

“This contract is an important next step in our long-term partnership with Raytheon, and the historic first production contract for NSM in the U.S.,” said Harald Annestad, Kongsberg Defense Systems president. “Kongsberg is committed to continuing the evolution of building and supporting NSM in the U.S. for the foreseeable future.”

The stealth design of the NSM allows the anti-ship missile to penetrate into shipboard defences. The NSM is effectively used in littoral and open sea environments. The airframe design and the high thrust-to-weight ratio enhance the manoeuvrability of the missile.

The missile has a length of 3.96m. It can carry a 125kg HE fragmentation warhead for a maximum range of more than 185km. The launch weight of the missile is 407kg. The NSM based Coastal Defence System (CDS) includes a fire distribution centre (FDC), sea surveillance and tracking radar and an NSM launcher fire unit.


The NSM can be fired from a range of platforms against a variety of targets. The passive homing missile travels in sea-skimming mode and can make advanced terminal manoeuvres in the terminal phase, to survive enemy air defences.


The missile, using GPS-aided mid-course guidance with a dual-band imaging infrared (IIR) seeker, detects and discriminates the targets. Autonomous target recognition (ATR) of the seeker ensures accurate detection and striking of sea or land based targets. A programmable fuse is used to detonate the missile’s warhead.

The NSM is launched into the air by a solid rocket booster which is jettisoned upon ignition. The Microturbo TRI-40 turbojet engine propels the missile towards its target with high subsonic speed.
