If the Home Fleet vanished in April 1940

What if a meteor destroyed the Home Fleet during the Norwegian campaign in April 1940?

Britain could recall overseas forces, seek ships from allies or other countries, and accelerate construction. Germany would not automatically gain naval supremacy.

The premise requires a disaster affecting widely dispersed Home Fleet ships, rather than one anchorage. Force H is initially suggested as a reserve, then excluded because it belongs after the fall of France. Britain could still recall ships from other stations and draw on the French fleet while France remained an ally. Buying or borrowing older American or Chilean battleships is another possibility. Ships already under construction would face pressure for immediate design decisions and completion. These resources offer a response to a severe crisis without establishing automatic German naval supremacy.
