HMS Porpoise (S01) was a Porpoise-class submarine of the Royal Navy. She was launched on 25 April 1956, commissioned on 17 April 1958,[1] and was decommissioned in 1982. Finally, she was sunk as a target in 1985[2] in torpedo trials, for which purpose she was painted bright red.

She had been used as a training target while still serving with the Navy; in 1979 her casing, ballast tanks and vents were reinforced so that unarmed torpedoes could be fired at her without the risk of sinking.

In 2000, a glacier in East Greenland was named after her [1]
