the aft set of torpedo tubes and replacing the forward triple mount with a quintuple set of tubes. From 1964, Visby and Sundsvall underwent a much more expensive reconstruction, being completely rearmed. As recommissioned on 14 October 1966, the two destroyers were armed with two Bofors anti-aircraft guns, one forward and one aft, with a quadruple Bofors anti-submarine rocket launcher replacing the torpedo tubes. The ships' bridges were enlarged and a platform for a helicopter fitted. The ships' radar fit was also updated. All four ships were redesignated as frigates on 1 January 1965. Decommissioning In the 1970s the Swedish government decided that the navy would give up its blue-water navy capacity and become a more coast-based navy. All frigates and destroyers were decommissioned. The first two Visby-class frigates left the navy in 1978 and in 1982 the remaining two followed. HSwMS Visby and HSwMS Sundsvall were used as target ships before being sold to Spain for scrapping. Ships References Notes Citations Sources Destroyer classes
