Churchill applied a First World War lesson by pausing large-warship work and demanding an emergency concentration on escorts. The yards, machinery, cranes, and fitting-out facilities used for capital ships did not map neatly onto the commercial and smaller naval yards building Flowers and Hunts. Moving people and priorities therefore disrupted programs that were already under way. Escorts would likely have entered service at roughly the same time without the pause, while carriers and battleships could have avoided their own costly delay.

How Churchill's construction pause disrupted rather than accelerated escorts
Pausing carriers and capital ships to force an escort crash program moved labor across mismatched yards and introduced disruption without solving the real bottlenecks.
