What would another few months of peacetime construction do for the Royal Navy if war began in spring 1940?
Short answerIt would likely add carriers and escorts while bringing the King George V and Lion programs substantially closer to operational strength.
NotesThe Royal Navy could begin the war with roughly two additional carriers and more escorts if Germany waited until April 1940. The King George V class would be farther into service, while Lion and Temeraire would have enjoyed an uninterrupted year of construction under mounting war pressure. The gain would be a broader improvement in fleet readiness and the production pipeline.
