The Fridtjof Nansen Class frigates have an integrated weapon system based on the Aegis command system in service on US Navy Ticonderoga cruisers and Arleigh Burke destroyers. The Nansen Class frigates can support one medium-sized helicopter, such as the NH90 naval helicopter. ASW systems include the MSI 2005F combat system, CAPTAS Mk 2 V1 Combined Active / Passive Towed Array Sonar and Spherion MRS 2000 hull-mounted sonar. The Evolved SeaSparrow Missile (ESSM), developed by Raytheon with an international co-operative of ten NATO countries, has a new rocket motor. The integrated weapon system is based on the Aegis combat system with AN/SPY-1F radar and will support inter-operability of Norwegian Navy. The welded steel 132m monohull has 13 watertight compartments for enhanced survivability. The vessel's CODAG propulsion has one GE LM 2500 19.2MW gas turbine and two Navantia Bravo 12V 4.5MW diesel engines. The five Nansen Class anti-submarine warfare frigates were built by Navantia of Spain for the Norwegian Navy. The vessels are: HNoMS Fridtjof Nansen (F 310), Roald Amundsen (F 311), Otto Sverdrup (F 312), Helge Ingstad (F 313) and Thor Heyerdahl (F 314). The first vessel was launched from Navantia’s Ferrol shipyard in June 2004. Sea trials of the Nansen with the Aegis weapon system and the new SPY-1F radar began in October 2005. The Nansen was commissioned in Ferrol in April 2006 and arrived in Oslo, Norway in June 2006.

The Otto Sverdrup (F 312) was launched in May 2006 and commissioned in April 2008. Helge Ingstad (F 313) was launched in November 2007 and commissioned in September 2009. “The five Nansen Class anti-submarine warfare frigates were built for the Norwegian Navy.” The last ship, Thor Heyerdahl (F 314), was launched in February 2009 and commissioned in January 2011. The Nansen Class replace Oslo Class vessels in service since 1966. The main contractor is Navantia (formerly Izar) of Spain and the Aegis weapon systems integrator is the US company, Lockheed Martin. The vessels are of modular construction and the completion of the first module of the hull (‘keel-stretching’) of the Fridtjof Nansen took place in April 2003. Lockheed Martin delivered the first Aegis system in December 2003. The main mission of the frigate is anti-submarine warfare and the ship is equipped to detect, identify, track, engage and attack hostile submarines. The ship is also equipped for anti-air warfare and anti-surface warfare roles and can carry out non-combatant tasks in peacetime. The ship houses a medical facility. Nansen Class frigate design The 4,600t ship has five decks and two superstructures. The welded steel, 132m monohull has 13 watertight compartments for enhanced survivability. The hull design is optimised for stability, sea-keeping and manoeuvrability and the hull appendages and propellers are designed for low hydrodynamic noise. The ship has a CODAG propulsion plant which gives a maximum transit speed of 27kt. NH90 ASW helicopter The ship has a helicopter landing deck and hangar which can support one medium-sized helicopter. Six AgustaWestland Lynx helicopters operated by the Norwegian Air Force are to be replaced by the NH Industries NH90 ASW helicopter on order for the Royal Norwegian Navy. The NH90, to be deployed on the Nansen frigates, will have Thales Underwater Systems’ flash sonics dipping sonar system and anti-submarine torpedoes. AEGIS command and control combat aircraft The integrated weapons system from Lockheed Martin is based on the Aegis combat system from Lockheed Martin and anti surface and MSI 2005F anti-submarine warfare systems from Kongsberg Def...
