USS Argonaut (SS-475)

USS Argonaut (SS-475)

USS Argonaut (SS-475) was a Tench-class submarine operated by the United States Navy (USN). Constructed at Portsmouth Navy Yard during the second half of 1944, Argonaut was commissioned into the USN in 1945 and operated during the final year of World War II, although her only contact with the Japanese was when she sank a junk in August.

During the 1950s, the submarine was modified for greater underwater endurance, and to carry a Regulus I missile. From 1963 to 1965, Argonaut operated in the Mediterranean.

The submarine was sold to Canada in 1968, commissioned into the Royal Canadian Navy as HMCS Rainbow (SS 75), and operated until the end of 1974. The submarine was returned to the United States, and scrapped in 1977.
