How many aircraft could Admiral and Incomparable conversions carry?

What aircraft capacity might converted Admiral or Incomparable-class hulls have achieved by the Second World War?

Roughly 72 to the 80s for an Admiral conversion and more than 100, perhaps as many as 144, for an Incomparable-sized carrier with deck parking and external lifts.

An Admiral-class conversion could carry at least 72 aircraft and perhaps an air group in the 80s. An Incomparable-sized carrier could exceed 100, with an upper counterfactual estimate of eight 18-aircraft squadrons, or 144 aircraft. Those totals depend on deck parking, external lifts, and squadron organization rather than on hull dimensions alone. Eighteen-aircraft squadrons would avoid creating an unwieldy number of squadron commands in very large air groups. An Admiral hull was broadly comparable with a Lexington but slightly stronger and faster, with room for a beamier flight deck and wider hangar. These figures are explicitly design-dependent estimates, but they show how larger conversion hulls might have altered British carrier doctrine.
