The alternative allowance would not automatically produce every permitted ship, and older carriers might still need to be retired to remain under the 310,000-ton ceiling. HMS Furious might have remained in service longer, though the enlarged allowance would not preserve every existing hull. Britain had six carriers in 1930 and soon seven, evidence of an existing institutional commitment to naval aviation. Implacable's later displacement shows how an extra few thousand tons could materially improve a British fleet carrier without demanding a radically larger design. The counterfactual changes design room and replacement pace while retaining financial and construction limits.

Treaty tonnage, not indifference, constrained British carriers
Britain already possessed the world's largest carrier count in 1930, but its 135,000-ton ceiling sharply limited replacement choices.
