| Built By: | Vickers (Barrow) |
| Build Group: | P2 |
| Fate: | Paid off June 1982, placed on disposal list 1983. Towed to Cammell Lairds for conversion as a target, painted bright orange for weapons testing during 1985 and was sunk the same year on October 20th. |
Porpoise was eventually decommissioned in 1982 and was sunk as a target in 1985 in trials for the Spearfish torpedo, for which purpose she was painted bright red.
She had also been used as a target while still serving with the Navy. In 1979 the casing, ballast tanks and vents were reinforced so that unarmed torpedoes could be fired at the submarine without the risk of sinking her.

A special group of navy divers is created when a disabled Nazi warship is discovered in a fjord in Norway. Commander Bolton (James Caan) is the Canadian expert designated to train the new unit. Their mission is to plant a bomb on the warship as it undergoes repairs. The hard-driving Bolton encounters resentment from the British soldiers he trains, but he ultimately earns their respect as a leader. Their intense training operation is interrupted by an attack of Nazi paratroopers just before the unit leaves for Norway. Spectacular underwater photography is seen in this World War II adventure story based on an actual mission
