American cruiser-to-carrier conversions show what the Royal Navy lacked without a similar stream of hulls. Britain could not redirect cruisers already under construction because treaty-era reductions had left too few in the programme. This left the fleet short of completed cruisers and narrowed its ability to adapt when naval aviation became more important. Industrial continuity and design evolution gave a fleet strategic flexibility that simple treaty tonnage totals miss.

Cruiser production also created carrier options
Continuous cruiser construction gave the United States hulls that could become carriers, while Britain's thinner programme removed that option as well as new cruisers.
