What changes if the Second World War begins in 1942?
Short answerBritain gains a far stronger escort force and more time for construction and modernization, producing a significantly more capable Royal Navy than Germany’s relative improvement.
NotesA war delayed until 1942 gives the Royal Navy a much stronger convoy screen. Roughly 60 Flower-class ships, a similar or larger number of Hunt-class escorts, and about 30 Black Swans could produce around 150 first-rate escorts. More time also allows refits for Hood and possibly Repulse, along with additional capital-ship construction and carrier modernization. The resulting British fleet changes much more than its German opponent.
