HMS Opportune (S20) was an Oberon-class submarine of the Royal Navy.
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 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]
Opportune was laid down by Scotts Shipbuilding and Engineering Company on 26 October 1962, and launched on 14 February 1964. [2] The boat was commissioned into the Royal Navy on 29 December 1964. [2]

On 15 February 1967, Opportune was in collision with sister submarine Orpheus when Opportune was leaving Portsmouth harbour as Orpheus was entering at night and in heavy weather, with only minor damage caused. Orpheus's commanding officer was found guilty of hazarding his vessel and was reprimanded. [3] [4] [5] In 1971, Opportune collided with a merchant ship, causing damage to the upper front part of the fin as well as both periscopes. [6]
Opportune attended the 1977 Silver Jubilee Fleet Review off Spithead when she was part of the Submarine Flotilla. [7]
Opportune was paid off on 2 June 1993.[ citation needed ] For several years the vessel resided at Pounds scrapyard in Portsmouth. [8] [9]
Every year since the vessel was scrapped, senior rates from the boat have annually met together to celebrate their service and life on the boat. [10]
HMS Ocelot (S17) is an Oberon-class diesel-electric submarine which was operated by the Royal Navy.
HMAS Ovens is an Oberon-class submarine, formerly of the Royal Australian Navy (RAN). She was one of six Oberons built for the Royal Australian Navy by the Scottish Scotts Shipbuilding and Engineering Company, and entered service in 1969. The vessel was named for Irishman and Australian explorer John Ovens (1788–1825) and for whom the Victorian river Ovens was named. During her career, Ovens was the first RAN submarine to deploy with the ANZUK force, and the first RAN submarine to fire an armed Mark 48 torpedo, sinking the target ship Colac. The boat was decommissioned in 1995, and is preserved at the Western Australian Maritime Museum as a museum ship.
The Oberon class was a ship class of 27 British-designed submarines operated by five nations. They were designed as a follow-on from the Porpoise class; physical dimensions were the same but stronger materials were used in hull construction and improved equipment was fitted.
