How a 1936 naval-treaty collapse could reshape British capital ships

How would the Royal Navy react if the Second London Naval Treaty collapsed in 1936?

It could redesign the unlaid King George V class with heavier guns and adopt larger armored carriers, while still expanding cautiously until treaty failure was certain.

The timing matters because the King George V class had not yet been laid down and the next carrier studies were still in transition. Without the treaty incentive for 14-inch guns, Henderson's preferred 15-inch alternative or a 16-inch design becomes plausible. The Illustrious program could also begin from a larger armored-carrier design closer to the original 27,000-ton Implacable concept. Funding caution would remain until the government knew another agreement was impossible, so the likely effect is heavier and somewhat larger ships rather than an instant unlimited building spree.
