Five King George Vs did not neatly replace five Royal Sovereigns, nor did six Lions simply replace six older capital ships. Britain had already paid to modernize several Queen Elizabeths, Royal Oak, Renown, and potentially Hood, so those proven ships would remain while new classes worked up. Planning for roughly seven capital ships against each of Italy, Germany, and Japan produces a target near nineteen to twenty-one ships before carriers and cruisers are counted. Keeping refitted veterans in commission gave the fleet depth while yards and budgets delivered the new hulls gradually. Interwar debt repayment had deliberately restrained naval growth so Britain could preserve credit for a future crisis, but the economy could expand construction if war did not consume it. Dominion shipbuilding in Canada or Australia could also contribute cruisers and other forces to the imperial system. Class-by-class procurement becomes a global force-structure problem shaped by theatres, finance, working-up time, and industrial capacity.

Why the Royal Navy retained old capital ships while building new ones
Separate seven-ship requirements against Italy, Germany, and Japan pushed Britain toward nineteen-to-twenty-one capital ships and made refitted veterans a bridge to new construction.
