An Army Air Corps would leave naval aviation inside the Royal Navy

How would the Second World War change if an Army Air Corps performed the RAF's role?

The Royal Navy would probably control carrier and maritime patrol aviation from the outset, while the Army developed its own fighter and close-support structure.

The Royal Navy would likely retain its own carrier aviation and long-range maritime patrol force if the Army Air Corps performed the historical RAF role. Continuous naval control would integrate aircraft requirements into carrier design much earlier. The Army might simultaneously develop a stronger fighter and close-support organization, with aircraft competing against light artillery in mobile formations.
