The Naval Strike Missile (NSM) is an anti-ship and land-attack missile developed by the Norwegian company Kongsberg Defence & Aerospace (KDA).

The original Norwegian name was Nytt sjømålsmissil (literally New sea target missile, indicating that it is the successor of the Penguin missile); the English marketing name Naval Strike Missile was adopted later.

Development[edit | edit source]

The Naval Strike Missile's initial serial production contract was signed in June 2007.[2] It has been chosen by the Royal Norwegian Navy for its new Fridtjof Nansen class frigates and Skjold class patrol boats. In December 2008 the NSM was selected by the Polish Navy, which ordered total 50 land-based missiles (including 2 for testing) under deals from 2008 and 2011, with delivery planned for 2013-2016.[3][4][5]

The final milestone was completed in June 2011 with tests at Point Mugu.[6] On 12 April 2011, the Norwegian Ministry of Defense announced phase 2 of development.[7]

On Wednesday, October 10, 2012, the Royal Norwegian Navy marked history by firing an NSM anti-ship missile for the first time. The vessel in question was the HNoMS Glimt, Skjold class patrol boat.[8]

On Wednesday, June 5, 2013, the Royal Norwegian Navy for the first time test fired an NSM missile carrying a live warhead against a target vessel. The decommissioned Oslo class frigate HNoMS Trondheim was hit and the weapon functioned as intended.[9][10]

In June 2013 Poland completed the Coastal Missile Division equipped for the beginning with 12 NSM and 23 vehicles on Jelcz chassis (inc. six launchers, two TRS-15C radars, six fire control and three command vehicles).[11] Ultimately, the Coastal Missile Division will be equipped with 48 missiles and six launchers. It is believed, Poland is going to establish second missile division in near future.

Design and features[edit | edit source]

The state-of-the-art design and use of composite materials is meant to give the missile sophisticated stealth capabilities. The missile will weigh slightly more than 400 kg (880 lb) and have a range of at least 185 km (100 nm). NSM is designed for littoral waters ("brown water") as well as for open sea ("green and blue water") scenarios.

Like its Penguin predecessor, NSM is able to fly over and around landmasses, travel in sea skim mode, and then make random manoeuvres in the terminal phase, making it harder to stop by enemy countermeasures. While the Penguin is a yaw-to-turn missile, NSM is based on bank-to-turn flight (see Yaw (flight) and flight control).

The target selection technology provides NSM with a capacity for independent detection, recognition, and discrimination of targets at sea or on the coast. This is possible by the combination of an imaging infrared (IIR) seeker and an onboard target database. NSM is able to navigate by GPS, inertial and terrain reference systems.

After being launched into the air by a solid rocket booster which is jettisoned upon burning out, the missile is propelled to its target in high subsonic speed by a turbojet sustainer engine—leaving the 125 kg multi-purpose blast/fragmentation warhead to do its work, which in case of a ship target means impacting the ship at or near the water line.

Joint Strike Missile[edit | edit source]

A multi-role version of the NSM is in development. This missile is called Joint Strike Missile (JSM) and will feature an option for ground strike and a two-way communications line, so that the missile can communicate with the central control room or other missiles in the air. This missile will be integrated with the Lockheed Martin F-35 Lightning II "Joint Strike Fighter". Studies have shown that the F-35 would be able to carry two of these in its internal bays, while additional missiles could be carried externally.

According to Kongsberg, this "multi-role NSM" is the only powered anti-ship missile that will fit inside the F-35's internal bays.[12] Lockheed Martin and Kongsberg have signed a joint-marketing agreement for this air-launched version of the NSM, as well as an agreement committing both parties to integrating the JSM on the F-35 platform.[13][14] The project is funded by Norway and Australia.[15] Kongsberg signed a contract for the first phase of development of the JSM in April, 2009, which is scheduled for completion within 18 months.[16]

Improved features for the Joint Strike Missile include:

  • Shape changed to fit in F-35 internal bay.[17]
  • Ability to attack sea and land based targets
  • Aerial launch platform (F-35)
  • Improved range over NSM to 280 km [18]
  • Long-term, production start in 2013

The JSM will have multicore computers running Integrity real-time operating system from Green Hills Software.[19]

Kongsberg is studying methods to deploy the JSM from Norway's submarines.[20]
