During the last year of World War II the once surface-bound diesel-electric U-boat ushered in the age of 'total undersea war' with the introduction of an air mast, or 'snorkel' as it became known among the men who served in Doenitz's submarine fleet. U-boats no longer needed to surface to charge batteries or refresh air; they rarely communicated with their command, operating silently and alone among the shallow coastal waters of the United Kingdom and across to North America. At first, U-boats could remain submerged continuously for a few days, then a few weeks, and finally for months at a time, and they set underwater endurance records not broken for nearly a quarter of a century. The introduction of the snorkel was of paramount concern to the Allies, who strived to frustrate the impact of the device before war's end. Every subsequent wartime U-boat innovation was subordinated to the snorkel, including the new Type XXI Electro-boat wonder weapon'. The snorkel's introduction foreshadowed the nearly un-trackable weapon and instrument of intelligence that the submarine became in the postwar world.
