Detailed explanation-1: -The formidable U-boats (unterseeboots) prowled the Atlantic armed with torpedoes. They were Germany’s only weapon of advantage as Britain effectively blocked German ports to supplies. The goal was to starve Britain before the British blockade defeated Germany.

Primitive subs were used with mixed results from the Revolutionary War up until World War I, when advances were made in propulsion and torpedoes. However, it was the Germans who most effectively used their submarines, called U-boats, against allied shipping during World War I.
