Repair capacity as wartime force generation

Dockyards support naval expansion by returning damaged ships to service instead of forcing new construction to replace every serious casualty. The argument is that British warship survival improved markedly after 1942 because damaged destroyers and larger vessels could usually be repaired. Britain and the United States had begun expanding yards before entering their periods of maximum wartime production, showing that industrial mobilisation took years rather than a sudden turn of a tap. Germany, Italy, and Japan possessed less repair capacity and faced sharper choices between restoring damaged ships and building desperately needed new ones. Repaired hulls allowed new construction to increase fleet size instead of merely covering losses.
