Early in the war, the unrestricted use of submarine warfare against British Merchant shipping nearly doomed the nation. After supply ships began crossing from the United States, they became easy prey for the veteran U-Boat commanders. The primary use of a submarine, even today, is to ensure that you control the sea access lanes to your enemy, by attacking ships or submarines.
Eventually, the Allies countered the threat and ultimately doomed the U-Boats. Organized, Escorted Supply Convoys, escorted by Navy Destroyers and Frigates that could make the Transatlantic crossing to England, proved a real problem for the U-Boats. The use of Merchant Carriers, Merchant Ships that could carry & launch 4 Recon aircraft, also helped to nullify the advantage. The addition of RADAR on Navy ships meant a U-Boat at Periscope Depth or surfaced could be detected, even at night; and the ultimate employment of long-range bombers sealed the U-Boats fate. They never again enjoyed the success they had early in the war.
