| 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.

HMS Conqueror is Britain's most famous submarine. It is the only sub since World War Two to have sunk an enemy ship. Conqueror's sinking of the Argentine cruiser Belgrano made inevitable an all-out war over the future of the Falkland Islands, and sparked off one of the most controversial episodes of twentieth century politics.
The controversy was fuelled by a war-diary kept by an officer on board HMS Conqueror, and as a young TV producer in the 1980s Stuart Prebble scooped the world by locating the diary's author and getting his story on the record. But in the course of uncovering his Falklands story, Stuart Prebble also learned a military secret which could have come straight out of a Cold War thriller. It involved the Top Secret activities of the Conqueror in the months before and after the Falklands War.
Prebble has waited for thirty years to tell his story. It is a story of incredible courage and derring-do, of men who put their lives on the line and were never allowed to tell what they had done. This story, buried under layers of official secrecy for three decades, is one of Britain's great military success stories and can now finally be told.
