By the early 1950s, the French Navy had in service a number of aircraft carriers, the most modern of which was . However, all of them were small and increasingly incapable of operating modern aircraft, which were steadily increasing in size. To ensure French independence in defence matters, a new class of two modern fleet carriers was envisaged. Displacing just under 35,000 tons each, the new ships would be slightly smaller than the Royal Navy's newly commissioned 43,000 ton ships, but they would be capable ships for their size built from scratch to take advantage of the latest ideas in aircraft carrier design, including angled flight deck, steam catapults and mirror landing aid, and would operate a brand new generation of French designed carrier based aircraft.
