HMS Ocelot (S17)
HMS Ocelot (S17) was an Oberon-class diesel-electric submarine laid down by HM Dockyard at Chatham in Kent on 17 November 1960, launched on 5 May 1962 and commissioned on 31 January 1964. She joined the 3rd Flotilla based at HMNB Clyde, in Faslane. HMS Ocelot was the last submarine built for the Royal Navy at Chatham Dockyard, although three more 'O' class submarines were built for the Royal Canadian Navy, these were Ojibwa, Onondaga and Okanagan.
HMS Ocelot 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.
