The Oslo class frigate is a Royal Norwegian Navy frigate design, based on the US Navy Dealey class destroyer escorts. The forward hull was customized to suit Norwegian sea conditions better (higher freeboard) and several sub-systems were European built.
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).
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.
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.
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.

The lead ship, Oslo, ran aground near Marstein island 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.
Bergen was decommissioned in August 2005.
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. The frigate was towed to port in Bergen by the coast guard vessel KV Tromsø.
HNoMS Trondheim was used after decommissioning as a target ship. On 5 June 2013, she was severely damaged in a test of the Norwegian-designed Naval Strike Missile system off the coast of the island Andøya.
