How Britain reached twenty-five carriers under construction

How did British yards free enough capacity to have roughly twenty-five carriers building at the end of World War II?

The yards were progressively brought to full wartime output; Britain had the capacity, but unlike the United States it had to complete the buildup while already fighting.

There was no single dramatic release of dock space. Continuous working-up, sustained orders, and full commitment brought the yards online, while America's extra peacetime years gave its industry a head start. British yards took several wartime years to approach their maximum pace.
