But there could have been back in the 1960s.
CVA-01 – to give the ship her working title – would have been 33ft longer and 46ft wider than the modern ships.
She would have had a ship’s company of 3,250 compared to 1,600, both including aircrew.
Her range would have been 3,000 nautical miles, less than the modern ships and she would have displaced 55,000 tons compared to today’s 65,000 tonnes.
She would have carried 40 aircraft.
But because of government bickering and inter-service rivalry no order was ever placed and the whole idea was dropped by the Labour government in 1966.
The designer, Louis Rydill, said it was the happiest day of his life when the ship was cancelled.
Thanks to a stream of design changes and budget cuts, the whole construction had become a nightmare.
