British and American carrier design exchange

How much would American carrier design change if a U.S. yard built a Malta-class carrier for the Royal Navy?

Probably little, because Midway and Malta already emerged from extensive wartime exchange between the two construction organizations.

The Midway class represented an American armored-carrier answer developed with access to British experience, while Malta incorporated British study of American large-carrier practice. Wartime repair requirements forced the U.S. Bureau of Ships and Britain's Director of Naval Construction to share practical details, not merely high-level reports. British yards needed to repair American ships and American facilities needed to support British ones. A U.S.-built Malta might affect production, but it would not suddenly reveal an unfamiliar design philosophy to either navy.
