'''HMS ''Ocelot'' (S17)''' is an {{sclass|Oberon|submarine|0}} diesel-electric [[submarine]] which was operated by the [[Royal Navy]].

==Design and construction==
{{main|Oberon-class submarine}}
The ''Oberon'' class was a direct follow-on of the [[British Porpoise-class submarine|''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]].<ref>{{cite book |last=Chant |first=Christopher |title=Submarine Warfare Today: The World's Deadliest Underwater Weapons Systems |publisher=Silverdale Books |location=Wigston |date=2005 |isbn=1-84509-158-2|oclc=156749009}}</ref>

As designed for British service, the ''Oberon''-class submarines were {{convert|241|ft}} in length [[between perpendiculars]] and {{convert|295.2|ft}} in [[length overall]], with a beam of {{convert|26.5|ft}}, and a draught of {{convert|18|ft}}.<ref name=Moore490>{{cite book |editor=Moore, John |title=Jane's Fighting Ships 1977-78 |edition=80th |year=1977 |series=[[Jane's Fighting Ships]] |publisher=Jane's Yearbooks |location=London |isbn=0531032779 |oclc=18207174 |page=490}}</ref> Displacement was 1,610 tons standard, 2,030 tons full load when surfaced, and 2,410 tons full load when submerged.<ref name=Moore490/> Propulsion machinery consisted of two Admiralty Standard Range 16 VMS diesel generators, and two {{convert|3,000|shp}} electric motors, each driving a {{convert|7|ft|m|adj=mid|-diameter}} three-bladed propeller at up to 400&nbsp;rpm.<ref name=Moore490/> Top speed was {{convert|17|kn}} when submerged, and {{convert|12|kn}} on the surface.<ref name=Moore490/> Eight {{convert|21|in|cm|adj=mid|-diameter}} torpedo tubes were fitted (six facing forward, two aft), with a total payload of 24 torpedoes.<ref name=Moore490/> The boats were fitted with Type 186 and Type 187 sonars, and an I-band surface search radar.<ref name=Moore490/> The standard complement was 68: 6 officers and 62 sailors.<ref name=Moore490/>

''Ocelot'' was laid down by [[Chatham Dockyard]] on 17 November 1960, and launched on 5 May 1962.<ref name=Moore490/> The boat was commissioned into the Royal Navy on 31 January 1964.<ref name=Moore490/> ''Ocelot'' was the last submarine built for the Royal Navy at Chatham Dockyard, although three more ''Oberon''s; ''[[HMCS Ojibwa (S72)|Ojibwa]]'', ''Onondaga'' and ''Okanagan''&mdash;were built for the [[Royal Canadian Navy]].{{citation needed|date=June 2015}}

==Operational history==
After commissioning, ''Ocelot'' was assigned to the [[3rd Submarine Squadron (United Kingdom)|3rd Submarine Squadron]], based at [[HMNB Clyde]], in [[Faslane]], serving there for three years.<ref>{{cite news|title=Ships of the Royal Navy: No. 150: Wild Cat Joining Dolphin Squadron | newspaper = [[Navy News]] |date=May 1968 |page=3|url=https://issuu.com/navynews/docs/196805 |access-date=20 August 2018}}</ref>

During the 1960s, ''Ocelot'' took part in clandestine missions.<ref>{{cite news|url=https://www.bbc.co.uk/news/magazine-25019489|title=BBC News - Life on a British Cold War submarine|date=12 December 2013|work=[[BBC Online]]|access-date=12 December 2013}}</ref> ''Ocelot'' attended the 1977 Silver Jubilee [[Fleet Review]] off [[Spithead]] when she was part of the Submarine Flotilla.<ref>Official Souvenir Programme, 1977. ''Silver Jubilee Fleet Review'', HMSO</ref>

==Decommissioning and fate==
HMS ''Ocelot'' was paid off in August 1991 as the conventional submarine fleet of the RN began to decline, making way for the nuclear fleet. She was sold in 1992 and preserved as a fully tourable museum in [[Chatham Historic Dockyard]].
