Aircraft Carriers of the 1920s & 1930s Long Patrol Part 4: 1920s Aircaft Carriers of the Big 3

A standardized 1934 reference puts carriers on common footing, but its as-built figures cannot capture every later alteration by governments, navies, crews, and sailors.

HMS Argus links interwar experimentation with naval-aviation training and wartime aircraft-ferry missions to Malta, while her modest specifications set the decade's baseline.

Rounded flight-deck bows, accelerators, restraining wires, barriers, and arresting gear show how launch and recovery systems changed as aircraft grew heavier.

USS Langley's collier conversion shows how machinery position, exhaust trunking, flight-deck turbulence, and command redundancy shaped carrier islands.

Hosho's compact purpose-built form contrasts with HMS Eagle's larger battleship conversion, heavy guns, smaller air group, and possible flagship role.

HMS Hermes shows how a purpose-built carrier could support China Station deployment, a distributed British carrier force, and a balanced three-flight air group.

HMS Furious's 1925 configuration combined 31-knot speed, a 35-aircraft group, and an almost flush deck, giving her a brief lead over rival carriers.

Akagi was formidable, but Lexington and Saratoga used battlecruiser hulls to deliver greater speed, size, and 80-aircraft groups at the end of the decade.

Britain still fielded more carriers, but Lexington and Saratoga helped frame the case for a large Royal Navy strike carrier in the Far East.

HMS Courageous's lower flying-off deck and Kaga's enormous funnel show how airflow, exhaust routing, and hangar access affected carrier capacity.

In less than ten years, experimental conversions gave way to larger, faster carriers with more efficient flight operations and stronger air groups.

British plans favored maintenance and endurance for a long commerce war, while American and Japanese plans emphasized a concentrated first strike and rapid aircraft replacement.
