The Fridtjof Nansen-class frigates are a class of frigates that are the main surface combatant units of the Royal Norwegian Navy. 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). The total projected cost for all five ships is 21 billion kr (about USD 2.54 billion).[not in citation given][1] 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.

Design[edit]

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 Álvaro de Bazán-class frigates, including the incorporation of Lockheed Martin's AEGIS combat system.

Improvements[edit]

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 NFH NH90 helicopters, with the role as an extended "arm" of the frigates' ASW and ASuW capabilities.

Service history[edit]

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.[2][3]

Fridtjof Nansen's engagement in Operation Atalanta was carried out without a permanently stationed helicopter.[4] 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).[5]

In November 2009 she became involved in a firefight with suspected pirates after being attacked while inspecting a fishing vessel.

In December 2013 HNoMS Helge Ingstad and the Danish Absalon-class support ship HDMS Esbern Snare were sent to the Syrian port of Latakia to escort the Norwegian registered RoRo cargo ship Taiko and the Danish cargo ship Ark Futura, which transported Syrian chemical weapons to Italy where they were handed over to a United States Navy ship for destruction in international waters.[6][7]

In 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.[8]. In the early hours of 13 November the vessel sank with only smaller sections of the superstructure remaining above water.[9]

List of ships[edit]

The ships are named after explorers Fridtjof Nansen, Roald Amundsen, Otto Sverdrup, Helge Ingstad and Thor Heyerdahl.
