[edit] Construction
All ships were built at the Navy Main Yard in Horten, Norway between 1964 and 1966. The construction of the vessels was part of the Navy rebuilding program, approved by the Norwegian government in 1960. Half of the project expenses were funded by the United States as a part of the Mutual Defense Assistance Program (MDAP) (a program that ran from when it was passed by the Congress in October 1949 until 1967–68).
[edit] Modernization
In the late 1970s, the class received new armament, most notably Penguin, RIM-7 Sea Sparrow and Mark 32 torpedo launchers. Another modernization was carried out in the 1980s.
During 1995 and 1996, after HNoMS Oslo experienced an engine failure, and subsequently sank after sailing in heavy weather, the rest of the class was once again modernized. The hulls were strengthened, which in turn increased the displacement with 200 tonnes.[1]
All of the Oslo class are now retired, with HNOMS Narvik preserved as a museum ship. The Oslo class were replaced by the Fridtjof Nansen class frigates. This replacement started in mid-2006.
[edit] Ships
Five frigates of this class were built. All of them were modernized during the period 1987–1990. They bear the prefix KNM (Kongelig Norske Marine, meaning Royal Norwegian Navy) in Norwegian and HNoMS (His Norwegian Majesty's Ship) in English.

[edit] Oslo
The lead ship, Oslo, ran aground at Marsteinen on January 24, 1994. One officer was killed in the accident. The next day, on January 25, she was taken under tow. She sank on the same day in Korsfjorden outside Steinneset in Austevoll county.
[edit] Stavanger
Stavanger was decommissioned in 1998. She was later used for target practice and sunk in 2001 by a single DM2A3 torpedo launched from the Ula-class submarine Utstein (S 302). [3]
[edit] Bergen
Bergen was decommissioned in August 2005.
[edit] Trondheim
On March 17, 2006 at 20:10 CET, the Trondheim ran aground outside of the Lines island in Sør-Trøndelag. No personal injuries among the 121-man crew were reported. The incident was reported from the ship itself, and at 20:30 it came loose again. Water flooded two compartments (paint storage and forward pump room) of the ship. The compartments were sealed and three ships were sent to assist the frigate.[4] The frigate was towed to port in Bergen by the coast guard vessel KV Tromsø.[5]
[edit] Narvik
Narvik, the last active ship of the class, has been transferred to the Royal Norwegian Navy Museum in Horten.[6]
