Oslo Class Frigate - Modernization

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.

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.
