Question

What was the key German weapon in the battle for the Atlantic?

Answer 1

The U boat.

Explanation:

The submarines were the most effective weapon that the German had in the battle of the Atlantic.

German surface ships like the Bismark had a very short effective role in the Battle for the Atlantic. The Bismark was sunk very quickly.

German warplanes had a very limited range. This did not allow the German air force to have an effect on the battle for the Atlantic. German planes had a larger effect on the Battle in the Bay of Biscay off the coast of France. Also planes operating out of Norway were effective on the Murmask convoys to Russia.
