Norway’s Kongsberg Defence & Aerospace AS has signed a contract, worth NOK203 million (~$21 million), with Raytheon Missile Systems to supply Naval Strike Missiles (NSM) for the U.S. Navy’s Over-The-Horizon Weapon System (OTH WS) program.
Raytheon is the prime contractor to the U.S. Navy for the OTH WS program.
This order is related to the OTH WS framework agreement announced on 31 May 2018 with a total cumulative scope of around $848 million, said a Kongsberg statement.
It was announced in April 2018 that Naval Strike Missile, offered by Raytheon and Kongsberg Gruppen, was selected by the U.S. Navy to meet the over-the-horizon requirement for its littoral combat ships (LCS) and future guided-missile frigates [FFG(X)].
According to the U.S. Navy, the missile meets its over-the-horizon requirements for survivability against high-end threats, demonstrated lethality, easy upgrades and long-range strike capability.
The NSM missile was first successfully demonstrated from the Navy’s Independence-class littoral combat ship USS Coronado (LCS-4) on 24 September 2014.
Last month, Raytheon was awarded a contract modification, worth around $35.9 million, by the U.S. Navy for over-the-horizon weapon systems. Under this contract, Raytheon will manufacture and deliver over-the-horizon weapon systems that consist of encanistered missiles (EM) loaded into launching mechanisms (LM) and a single fire control suite (FCS).
In 2019, the U.S. Marine Corps integrated a land-based Naval Strike Missile into its force structure, sharing costs and interoperability with the Navy.
Naval Strike Missile (NSM)
The Naval Strike Missile is a long-range, precision strike weapon that can find and destroy enemy ships at distances up to 100 nautical miles away. The stealthy missile flies at sea-skimming altitude, has the terrain-following capability and uses an advanced seeker for precise targeting in challenging conditions.
After being launched into the air by a solid fuel rocket booster which is jettisoned upon burning out, the missile is propelled to its target in high subsonic speed by a Microturbo TRI 40 turbojet sustainer engine.
The Naval Strike Missile eludes enemy radar and defense systems by performing evasive maneuvers and flying at sea-skimming altitude. NSM uses an advanced seeker for precise targeting and carries a 500-pound class warhead with a programmable fuze.
According to Raytheon, NSM is also suited for land attack missions because it can climb and descend with the terrain.
