Submarines of the class were in service until 2000. The Oberons operated during 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. Thirteen of the submarines were operated by the Royal Navy, six by the Royal Australian Navy, three by the Brazilian Navy, three by the Royal Canadian Navy/ Canadian Forces Maritime Command (plus two ex-Royal Navy boats later acquired for non-commissioned roles), and two by the Chilean Navy. The submarines were built between 19 by four shipyards: Cammell Laird (4), Chatham Dockyard (6), Scotts Shipbuilding and Engineering Company (11) and Vickers-Armstrongs (6).

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. The Oberon class was a ship class of 27 British-designed submarines operated by five nations.
