At the end the article on the loss of HMS Sussex, 1693-94 (The Argus, February 26), it was stated the Sussex of 1928 was an aircraft carrier.

It was a heavy cruiser, armed with eight-inch guns. It did carry an aircraft, as did many cruisers. They were launched by catapult for reconnaissance.

At the start of the Second World War, Britain had seven carriers, the new Ark Royal, Hermes (the navy's first purpose-built carrier), Furious, Glorious, Courageous (all converted from battle cruisers), the Eagle (a converted battleship) and the Argus of 1918 (the world's first flat-top, a converted liner).

The Argus was mainly used for training but several times had a more active role, such as providing air cover for convoys and launching fighters to cover the North African landings.
