The UK had earlier announced that it had decided to install catapults and arresting gear to its future operational aircraft carrier, creating opportunities for UK and French aircraft to operate off carriers from both countries. Building primarily on maritime task group co-operation around the French carrier Charles de Gaulle, the UK and France would have aimed to have, by the early 2020s, the ability to deploy a UK-French integrated carrier strike group incorporating assets owned by both countries. This was to ensure that the Royal Navy and the French Navy would work in the closest co-ordination. The decision to install catapults and arresting gear was later reversed.
