A thousand-aircraft interwar Fleet Air Arm

How far would British carrier aviation advance if the Royal Navy inherited a vast carrier fleet in 1921?

The Fleet Air Arm would gain early independence and could become larger than the RAF.

With roughly fifteen large carriers, the Royal Navy would need several hundred to about a thousand aircraft. Air Ministry control of procurement would become difficult to sustain when the naval requirement rivaled or exceeded the land-based air force. The scale of the fleet would therefore likely restore naval control of aviation much earlier than it occurred historically. For much of the interwar period, the Fleet Air Arm could become Britain's dominant air service rather than a subordinate specialist branch.
