U-100 was detected by the primitive radar on the destroyer HMSVanoc, rammed and sunk. With the exception of the Japanese invasion of the Alaskan Aleutian Islands, the Battle of the Atlantic was the only battle of the Second World War to touch North American shores.

The battle marks the turning point on the Mediterranean front. In the Battle of the Denmark Strait, the battlecruiser HMSHood was blown up and sunk, but Bismarck was damaged and had to run to France. ASDIC produced an accurate range and bearing to the target, but could be fooled by thermoclines, currents or eddies, and schools of fish, so it needed experienced operators to be effective. The best source proved to be the codebreakers of B-Dienst who had succeeded in deciphering the British Naval Cypher No. These raids were unsuccessful and the Luftwaffe had been seriously damaged. Blair attributes the distortion to "propagandists" who "glorified and exaggerated the successes of German submariners", while he believes Allied writers "had their own reasons for exaggerating the peril".

Allied convoys transporting military equipment and supplies. One crucial development was the integration of ASDIC with a plotting table and weapons (depth charges and later Hedgehog) to make an anti-submarine warfare system.
