The total projected cost for all five ships in 2009 was 21 billion kr (about USD 2.44 billion).[3] As of November 2018, four are in active service and one has sunk and was subsequently scrapped.
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 operated six NFH NH90 helicopters, with the role as an extended "arm" of the frigates' ASW and ASuW capabilities but these will be taken out of services (2022) and returned to NH Industries.
Service history
On 26 February 2009, the Norwegian government decided to deploy Fridtjof Nansen to the Gulf of Aden, thereby participating in the ongoing Operation Atalanta, the European Union's counter-piracy campaign in Somalia. Fridtjof Nansen joined the campaign in August 2009.[4][5]
Fridtjof Nansen's engagement in Operation Atalanta was carried out without a permanently stationed helicopter.[6] Mainly due to delays in delivery of the new NH-90, the ship was equipped with two fast RHIBs for its onboard contingent of maritime special operations forces (Marinejegerkommandoen).[7]
In November 2009 she became involved in a firefight with suspected pirates after being attacked while inspecting a fishing vessel.[citation needed]
On 8 November 2018, while returning from participation in Exercise Trident Juncture, Helge Ingstad was involved in a collision with a Maltese-registered oil tanker, Sola TS, that severely damaged the frigate and caused a severe list that placed it in serious danger of sinking in spite of its position. The frigate was successfully beached to prevent it sinking and allow the crew to be evacuated.[10] In the early hours of 13 November the vessel partially sank with only smaller sections of the superstructure remaining above water.[11] The vessel was recovered but with the cost of repair prohibitive it has been decommissioned and was scrapped.[12]

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 amp 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 Improvements EditThe
