The '''''Oberon'' class''' was a [[ship class]] of 27 British-designed [[submarine]]s operated by five nations. They were designed as a follow-on from the [[British Porpoise-class submarine|''Porpoise'' class]]; physical dimensions were the same but stronger materials were used in hull construction and improved equipment was fitted.<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 |page={{page needed|date=June 2015}}}}</ref>

The ''Oberon''s 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. Submarines of the class were in service until 2000.

The ''Oberon'' class was arguably the best conventional submarine class of its time,<ref name="brown&moore"/> with a reputation for remarkable quietness. The quietness of the ''Oberon'' vessels enabled them to operate into the late 20th century until replaced by newer classes such as the [[Collins-class submarine|''Collins'']] and [[Upholder/Victoria-class submarine|''Victoria'']] classes in Australia and Canada, respectively.

The submarines were built between 1957 and 1978 by four shipyards: [[Cammell Laird]] (4), [[Chatham Dockyard]] (6), [[Scotts Shipbuilding and Engineering Company]] (11) and [[Vickers-Armstrongs]] (6).<ref name=Moore>{{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 |pages=26, 44, 63, 81, 490}}</ref> 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]].<ref name=Moore/>
