HMS Otus was a Royal Navy Oberon-class submarine launched in 1962. She was decommissioned in the early 1990s and is now a museum ship in Germany.
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 VTS diesel generators, and two 3,000-shaft-horsepower (2,200 kW) electric motors, each driving a 7-foot diameter (2.1 m) 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]
Otus was laid down by Scotts Shipbuilding and Engineering Company on 31 May 1961, and launched on 17 October 1962.[2] Sea trials were undertaken in Scottish waters, mainly Loch Long and Loch Fyne.[citation needed] The boat was commissioned into the Royal Navy on 5 October 1963.[2]
