The Hajen class (Shark class) was a submarine class built by Kockums and used by the Swedish Navy. The design was influenced by the German Type XXI submarine class. A total of 6 submarines were built in 1954-1958 and were kept in service until 1980.[1][2]

The first Hajen class submarine to be built was HSwMS Hajen in 1954, followed by HSwMS Sälen (1955), HSwMS Valen (1955), HSwMS Illern (1957), HSwMS Bävern (1958), and HSwMS Uttern (1958).
