Hermes

HMS Hermes was a British aircraft carrier built for the Royal Navy and was the world's first ship to be designed as an aircraft carrier, although the Imperial Japanese Navy's Hōshō was the first to be launched and commissioned. The ship's construction began during the First World War but not completed until after the end of the war, delayed by multiple changes in her design after she was laid down. After she was launched, the Armstrong Whitworth shipyard which built her closed, and her fitting out was suspended. Most of the changes made were to optimise her design, in light of the results of experiments with operational carriers.
