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). As of 2011, all five are in active service. The total projected cost for all five ships is 21 billion kr (about USD 2.5 billion).[1]

Design

The frigates were originally intended as a replacement for the aging Oslo-class frigates, with a primary focus on antisubmarine warfare (ASW). Eventually, the need for a robust anti-aircraft defense as well as the possibility of incorporating the Naval Strike Missile SSM 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

The new frigates are a great improvement over their predecessors, the Oslo-class frigates, not only in size, but also in personnel, capabilities and equipment. Compared to the old Oslo-class vessels, the new ships 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. This solves one of the problems with the Oslo class: lack of space and much discomfort for the crew. The frigates will also operate six new NFH NH90 helicopters, with the role as an extended "arm" of the frigates' ASW and ASuW capabilities.

Current activities

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 as a replacement 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 will transport Syrian chemical weapons to Italy where they will be handed over to a United States Navy ship for destruction in international waters.[6] [7]

List of ships

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