The Royal Navy's carrier force and construction pipeline in 1939

Which aircraft carriers did the Royal Navy have in 1939?

The list recalled from memory is Ark Royal, Courageous, Glorious, Furious, Eagle, Hermes, and Argus, with uncertainty over Argus's administrative status. Further carriers were launched, building, or on order.

The recalled list of carriers in service in 1939 includes Ark Royal, Courageous, Glorious, Furious, Eagle, Hermes, and Argus. Argus's position is uncertain: she may have been administratively in reserve while retaining a substantial crew and moving about. Illustrious, Formidable, and Victorious are listed as launched, with Indomitable, Implacable, and Unicorn on the slips and Indefatigable under order. This inventory is explicitly offered from memory, with the warning that Implacable and Indefatigable may have been placed in the wrong categories. The construction programme therefore matters alongside the ships already serving.
