Could steady interwar sloop building have changed World War II?

A modest annual program could have entered 1939 with trained crews, escort hulls, and industrial capacity already available.

Question

If Britain had maintained and distributed sloop production through the interwar years, how would that have changed World War II?

Short answer

A steady program could have supplied a large prewar escort force, reduced emergency construction, strengthened early convoy defense, and expanded the industrial and personnel base available for wartime growth.

Notes

Naval-treaty rules left Britain room to build escorts steadily throughout the interwar years. A distributed program of about eight sloops a year would have supplied both the Royal Navy and overseas forces with trained crews and immediately usable hulls. Britain would then have entered World War II with more convoy and base protection already in place, reducing reliance on an emergency Flower-class corvette program. The counterfactual illustrates how continuous low-cost construction preserves readiness that cannot be improvised after war begins.
