HMS Olympus was an Oberon-class submarine that served in the Royal Navy, and later in the Canadian Forces as a submarine trainer.

Design and construction

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

The Oberon class was a direct follow on of the Porpoise-class, with the same dimensions and external design, but updates to equipment and internal fittings, and a higher grade of steel used for fabrication of the pressure hull.[1]

As designed for British service, the Oberon-class submarines were 241 feet (73 m) in length between perpendiculars and 295.2 feet (90.0 m) in length overall, with a beam of 26.5 feet (8.1 m), and a draught of 18 feet (5.5 m).[2] Displacement was 1,610 tons standard, 2,030 tons full load when surfaced, and 2,410 tons full load when submerged.[2] Propulsion machinery consisted of 2 Admiralty Standard Range 16 VMS diesel generators, and two 6,000 shaft horsepower (4,500 kW) electric motors, each driving a Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value). 3-bladed propeller at up to 400 rpm.[2] Top speed was 17 knots (31 km/h; 20 mph) when submerged, and 12 knots (22 km/h; 14 mph) on the surface.[2] Eight 21-inch (530 mm) diameter torpedo tubes were fitted (six facing forward, two aft), with a total payload of 24 torpedoes.[2] The boats were fitted with Type 186 and Type 187 sonars, and an I-band surface search radar.[2] The standard complement was 68: 6 officers, 62 sailors.[2]

Olympus was laid down by Vickers-Armstrongs on 4 March 1960, and launched on 14 June 1961.[2] The boat was commissioned into the Royal Navy on 7 July 1962.[2]

Operational history

In 1986, Olympus appeared in the popular UK Channel 4 television game show Treasure Hunt. After rendezvousing with the submarine a few miles out of Plymouth Sound, presenter Anneka Rice watched on from the show's famous yellow helicopter as Olympus surfaced, before landing on her hull and receiving the episode's second clue from the vessel's captain, Lt. Cmdr. John Tuckett.[3]

Retired from the Royal Navy, Olympus was sold to the Canadian Forces in 1989 and was stationed as a non-operational training boat in Halifax. The ship was never commissioned and was disposed of along with the other Canadian Oberon-class submarines in the late 1990s.

Fate

In May 2005, the Halifax Chronicle-Herald announced that Maritime Command (MARCOM) was looking to sell Olympus and three other Canadian Oberons for scrap metal. MARCOM stated that the submarines were not in suitable condition to be used as museum ships, and predicted that each submarine would sell for between C$50,000 and C$60,000.[4]

In July 2011, Olympus started making her journey from Halifax to a scrapyard (International Marine Salvage) in Port Maitland, Ontario.[5]
