The Oslo-class frigate is a Royal Norwegian Navy frigate design of the 1960s, 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. Ships of the class operated until 2007, when they were replaced by the Fridtjof Nansen class.
