Sleipner-class corvette

The Sleipner class was a series of corvettes ordered as part of the Royal Norwegian Navy's 1960 fleet plan.^[1] It was intended to build five ships of the class, but because of economic problems only two were built; Sleipner and Æger.^[2]

Development

Sleipner was built by Nylands Mekaniske Verksted, Oslo, and Æger by Aker Mekaniske Verksted, Oslo, and handed over to the Royal Norwegian Navy between 1965 and 1967.^[3] The ships were armed with an American 3 in (76.2 mm) gun forward and a Bofors 40 mm gun aft, with a Terne III anti-submarine rocket launcher ahead of the 40 mm gun. The ships were fitted with American SQS-36 sonar.^[2]

The ships had their anti-submarine capabilities improved in 1972, when they were fitted with Mark 32 anti-submarine torpedo tubes.^[2] The ships were mainly used as training ships in the 1980s, although they did retain a wartime role as coastal escorts.^[2][4] They were again modernised between 1988 and 1989, with new sonar and gun fire control systems fitted.^[1] They were decommissioned in 1993.^[2]
