Steady cruiser construction and national force coverage

The illustrative British programme keeps a few light cruisers entering service annually and adds occasional heavy cruisers without imposing a wartime construction surge. Its slides include Super-Leander or Amphion and Southampton ideas, showing how regular orders could sustain both the force and the shipyard rhythm. At an 8,000-ton light-cruiser average and a 10,000-ton heavy-cruiser average, the allowance yields twenty-five light and twenty heavy cruisers, still short of Britain's desired seventy. Retained over-age ships and sixteen roughly 2,000-ton Tribal-class destroyers could cover part of the gap, producing an imperfect but workable worldwide force. The United States could absorb larger production, while Japan's 140,000-ton allocation is framed as an industrial sweet spot that permits more heavy and light cruisers without exceeding its practical capacity.
