Would larger carriers immediately produce larger aircraft?

Would the larger carrier allowance change naval-aircraft procurement straight away?

Not necessarily; aircraft and engine development, lift dimensions, and hangar design matter more directly than the carrier's total displacement.

A larger hull gives designers more options, but it does not automatically create a new generation of aircraft. Engines and airframes must mature on their own technological schedules. Lifts and hangars then translate those aircraft dimensions into practical limits aboard ship. The treaty may eventually enable larger air groups or more spacious arrangements, but displacement is not the sole driver of procurement.
