The Oberon class was a ship class of 27 British-designed submarines operated by five different nations. They were designed as a direct follow-on from the Porpoise class: physical dimensions were the same, but stronger materials were used in hull construction, and updated equipment was fitted.[1]
The Oberons operated during the height of the Cold War, with duties including surveillance, tracking of other ships and submarines, delivery and retrieval of special forces personnel, and serving as targets for anti-submarine training. Submarines of the class were in service until 2000. As of 2015, eight of the submarines are preserved intact as museum vessels, another three are partially preserved (with some exterior portions of the submarine on display), and one is in private ownership and awaiting conversion for display. The rest have been sold for scrap, including one former museum vessel.
A previous Oberon named Onyx became the Canadian Ojibwa during construction: this submarine was ordered as a replacement. Preserved from 1991 to 2006 by the Warship Preservation Trust, then from 2006 to 2014 by the Submarine Heritage Centre.
^In the Royal Australian Navy, pennant numbers are normally rendered with a space between the letters and numbers, and use an expanded identifier similar to the United States Navy's Hull classification symbol (for example: HMAS Onslow's pennant is "SSG 60"). For this list, the Australian pennant numbers have been rendered in a style similar to the other nations in the list (single-letter flag superior, no space between letter and number)
