HMS Osiris (S13) was an Oberon-class submarine operated by the Royal Navy, notable for its design updates and service history. The Oberon class was a development of the Porpoise class, maintaining the same external dimensions but featuring advanced internal equipment, improved fittings, and a higher grade of steel for the pressure hull. The submarine measured approximately 241 feet (73 meters) between perpendiculars and 295.2 feet (90 meters) overall, with a beam of 26.5 feet (8.1 meters) and a draught of 18 feet (5.5 meters). Its displacement was 1,610 tons standard, increasing to 2,030 tons when surfaced at full load, and 2,410 tons submerged. Powered by two Admiralty Standard Range 16 VMS diesel generators and two 3,000 shaft horsepower electric motors, HMS Osiris could reach speeds of up to 17 knots when submerged and 12 knots on the surface. Its armament included eight 21-inch torpedo tubes—six forward and two aft—carrying a total of 24 torpedoes. The vessel was equipped with Type 186 and Type 187 sonar systems, along with an I-band surface search radar, enhancing its underwater detection and tracking capabilities. The typical crew complement comprised 68 personnel, including 6 officers and 62 sailors. Constructed by Vickers-Armstrongs, HMS Osiris was laid down on 26 January 1962, launched on 29 November 1962, and commissioned into the Royal Navy on 11 January 1964. Throughout her service, she participated in significant fleet activities, including attending the 1977 Silver Jubilee Fleet Review off Spithead as part of the Submarine Flotilla, marking her as a vessel of operational and ceremonial importance. Decommissioned in 1989, HMS Osiris was sold to the Canadian Forces primarily for spare parts. She was towed to Birkenhead for stripping at Cammell Laird shipyard, and following further dismantling at Garston, the remains were scrapped in 1992. The vessel remains a representative example of Cold War-era submarine design and capabilities within the Royal Navy.
