HMS Tiptoe (pennant number P332) was a British submarine of the third group of the T class. She was built by Vickers Armstrong, Barrow, and launched on 25 February 1944. She was one of two submarines named by Winston Churchill, and so far has been the only ship of the Royal Navy to be named Tiptoe. In 1955 she was involved in a collision with a coastal steamer whilst in Tromsø harbour. She was involved in escape trials off Malta in 1962, and the commanding officer was reprimanded in 1964 following an incident in the Firth of Clyde where she was run aground, and again in 1965 when she collided with HMS Yarmouth. Although originally named for the ability to sneak up on someone undetected, she maintained several links with ballet, including the Royal Ballet and ballet dancer Moira Shearer. She was scrapped in Portsmouth in 1975, while her anchor is on display in Blyth, Northumberland.
HMS Tiptoe was one of the group three of T-class submarines. She was named by Winston Churchill, with the intention to imply that it could approach the enemy silently as if on tiptoe, although the Royal Navy naming committee was against the name, stating that "it was derogatory to one of His Majesty's ships", but the Prime Minister had his way. The only other Royal Navy vessel to be named by Churchill was HMS Varangian.
She was part of the second batch of the third group to be ordered, in 1941. She was one of a number of boats which had an all-welded hull which increased diving depth to 350 feet (110 m), an increase of 50 feet (15 m). The torpedo armament was the same as the earlier group two, although by the time group three was coming into service it was realised that external torpedo tubes had major problems and affected the streamlining of the boats; the external tubes were abandoned in the following Amphion-class submarines. Because of expected use in tropical climates, boats of group three were equipped with freon blowers in order to deal with the increased temperatures.
