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 and HMS Ark Royal, while CVA-03 and CVA-04 would have replaced HMS Hermes and HMS Eagle respectively.
The planned four carrier class was soon reduced to three before further being reduced to two until 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 groups. Factors contributing to the cancellation of CVA-01 included inter-service rivalries, the huge financial costs of the proposed carrier against ongoing budgetary constraints, and the technical complexity and difficulties it would have presented in construction, operation, and maintenance. 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.
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.
