Turpin was laid down at Chatham Dockyard on 24 May 1943, was launched on 5 August 1944 and completed on 18 December 1944 (although she had already been commissioned on 1 October that year).[2] Turpin was a Group 3 T-class submarine, of all-welded construction.
At the end of the war, all surviving Group 1 and Group 2 boats were scrapped, but the group 3 boats (which were of welded rather than riveted construction) were retained and fitted with snort masts. In 1955, Turpin was inside the arctic circle on an ELINT mission, listening for specific frequency bands of Soviet radars. Suddenly, the ELINT specialist noted an unusual signal that was from a very short range radar. The operator registered that they were about to be rammed by a Soviet Navy surface vessel, and a crash dive was ordered. The Turpin submerged below a cold water line which allowed them to evade Soviet sonar and escape.[3]
Turpin was sold to the Israeli Navy in 1965, and renamed Leviathan, after a biblical sea monster.
The submarine was purchased by Israel, along with two of her T-class sisters, in 1965, HMS Truncheon and HMS Totem. She was commissioned into the Israeli Sea Corps in 1967.
She was eventually scrapped in 1978. A Dolphin class submarine named Leviathan was commissioned in 2000 to the Israeli Navy.
