The ships are named after famous Norwegian explorers, with the lead ship of the class bearing the name of Fridtjof Nansen, the Norwegian scientist, explorer and humanitarian. Five ships were ordered from Spanish shipbuilder Bazan (now Navantia). As of November 2018, four are in active service and one is out of service. Helge Ingstad was lost on 13 November 2018, after she sank following a collision with the Maltese-flagged tanker Sola TS on 8 November. She was run aground to prevent her sinking and to allow her crew to escape. Seven sailors were injured in the incident. The frigates were originally intended as a replacement for the aging Oslo-class frigates, with a primary focus on anti-submarine warfare (ASW). Eventually, the need for a robust anti-aircraft defense as well as the possibility of incorporating the Naval Strike Missile surface-to-surface missile produced by Norwegian company Kongsberg Defence & Aerospace led to a more multi-role design. The selection of Navantia as prime contractor led to the design being very similar to the Spanish Navy's Alvaro de Bazan-class frigates, including the incorporation of Lockheed Martin's AEGIS combat system. The Fridtjof Nansen-class frigates are larger, and have more personnel and equipment than the Oslo-class frigates. Compared to the Oslo-class vessels, the new vessels are 35 meters longer, nine meters taller and two meters deeper below water. They are also five meters broader and have three times the water displacement of the old ships. The frigates also operates six new NHIndustries NH90 helicopters, with the role as an extended arm of the frigates' ASW and ASuW capabilities. Unlike the other members of her class, HNoMS Thor Heyerdahl (F 314) was built with two 8-cell Mk.41 VLS modules instead of one. source: wikipedia class images for more images go to the individual ship's site F 310 HNoMS Fridtjof Nansen F 311 HNoMS Roald Amundsen F 312 HNoMS Otto Sverdrup F 313 HNoMS Helge Ingstad F 314 HNoMS Thor Heyerdahl ARMAMENT & DETAILS large flight deck & hangar Oto-Melara 76/62 Super Rapid gun (76mm / 3-inches / 62-caliber) Oto-Melara 76/62 Super Rapid gun (76mm / 3-inches / 62-caliber) and 8-cell Mk.41 VLS 16-cell Mk.41 VLS for 64 RIM-162 ESSM missiles (4 per cell) on F 314 Thor Heyerdahl Oto-Melara 76/62 Super Rapid gun (76mm / 3-inches / 62-caliber) a RIM-162 Evolved Sea Sparrow Missile was fired from the Mk.41 Vertical Launching System (VLS) a RIM-162 Evolved Sea Sparrow Missile was fired from the Mk.41 Vertical Launching System (VLS) Browning caliber .50 (12,7mm) machine gun and Kongsberg Defence Systems Naval Strike Missile (NSM) launcher Kongsberg Defence SEAPROTECTOR (caliber .50 / 12,7mm) remote-controlled machine gun system Kongsberg Defence SEAPROTECTOR (caliber .50 / 12,7mm) remote-controlled machine gun system a BAE Stingray Torpedo was loaded into one of the two 324mm twin torpedo tubes integrated twin launcher for Stingray torpedo aboard a Royal Norwegian Navy Fridtjof Nansen class Frigate ...
