All ships were built at the Navy Main Yard at Horten, Norway. The construction of the vessels was part of the Navy rebuilding program, approved by the government in 1960. They were built between 1964 and 1966. Half of the project was funded by the United States, as part of the Marshall Plan.

1 Vessels

Five frigates of this class were built. All ships were modernized in the late 1980s:

• Oslo (F300)
• Bergen (F301)
• Trondheim (F302)
• Stavanger (F303)
• Narvik (F304)

The lead ship, Oslo, ran aground at Marsteinen on January 24, 1994 and sank. Stavanger was taken out of service in 1998. It was later used for target practice and sunk in 2001. The other three (F301, F302, F304) remain in service today.
