HISTORY
Sleipner was baptized by Mrs Kjeholt at the launch. and the sister ship Æger was christened by Mrs Else Sørensen.
Sleipner was taken over by the Swedish Navy on 29 April 1965. The vessel was modernized in 1988, and for a period it was used as a cadet ship. Sleipner, which is no longer under command, was phased out in 1992.
Æger was taken over by Sjøfosvaret on 31 March 1967. Æger was modernized in 1989, and for a period used as a cadet ship, in the same way as Sleipner. Æger was also phased out in 1992
The Sleipner class was originally part of the 1960 fleet plan, and was therefore supposed to consist of 5 vessels, but this was later reduced to 2 vessels. these were built at Nyland’s workshop near Oslo, where they were originally classified as Patrol vessels, but at a later date reclassified as corvettes.
KNM Sleipner was sunk as a target vessel while testing torpedoes, and the sister ship KNM Æger was equipped as a remote-controlled target vessel. presumably this was in connection with the trial and testing of Penguin missiles
it was really hard to find any history about this, i have looked everywhere and this is what i found

Terne is a Norwegian anti-submarine weapon system, which uses rocket-thrown depth charges. It was developed by the Norwegian Defence Research Establishment in cooperation with the U.S. Navy in the late 1950s. The U.S. Navy used the Terne III system on a few destroyers in the early 1960s, but phased out the system after only a few years of use. The Norwegian Navy used Terne for many years after
