'''CVA-01''' was a proposed United Kingdom [[aircraft carrier]], designed during the 1960s. The ship was intended to be the first of a class that would replace all of the [[Royal Navy]]'s carriers, most of which had been designed before or during the [[Second World War]]. CVA-01 and CVA-02 were intended to replace {{HMS|Victorious|R38|6}} and {{HMS|Ark Royal|R09|6}}, while CVA-03 and CVA-04 would have replaced {{HMS|Hermes|R12|6}} and {{HMS|Eagle|R05|6}} respectively.<ref>{{citation |first=I |last= Sturton |title=CVA01. Portrait of a Missing Link |work=Warship 2014 |publisher=Conway |location= London |date=2014 |page=30}}</ref>

The planned four carrier class was soon reduced to three before further being reduced to two and finally, following a government review, in the form of the [[1966 Defence White Paper]], the project was cancelled, along with the proposed [[Type 82 destroyer]] class, which were intended primarily as escorts for [[carrier group]]s. Factors contributing to the cancellation of CVA-01 included [[Interservice rivalry|inter-service rivalries]],<ref>{{cite book |last=Brown |first=Eric |author-link=Eric Brown (pilot) |date=2007 |title= Wings on my Sleeve |publisher=Weidenfeld and Nicolson |pages=255–257  |isbn=978-0-7538-2209-8}}</ref> the huge financial costs of the proposed carrier against ongoing budgetary constraints,<ref name="Hampshire">{{cite book | last=Hampshire | first=Edward | title=From East of Suez to the Eastern Atlantic | publisher=Routledge | date=2016-04-15 | isbn=978-1-317-13234-9 | page=3-4}}</ref> and the technical complexity and difficulties it would have presented in construction, operation, and maintenance.<ref name="Hampshire"/> Some historians also cite the increased role played by land-based aircraft in providing a nuclear deterrent and that naval leadership at the time presented their need for the carriers poorly in government.<ref name="Hampshire"/>

Had CVA-01 and CVA-02 been built, it is likely they would have been named HMS ''Queen Elizabeth'' and HMS ''Duke of Edinburgh'' respectively.<ref>{{Cite web |url=http://web.ukonline.co.uk/aj.cashmore/britain/british-carriers.html |title=British Fleet Carriers |archive-url=https://web.archive.org/web/20070915094338/http://web.ukonline.co.uk/aj.cashmore/britain/british-carriers.html |archive-date=2007-09-15 }}</ref>
