This had been a very successful tactic used by British submarines in the Baltic Sea and Bosporus during World WarI, but it would not work if port approaches were well-patrolled. Greater co-operation with supporting aircraft was also achieved. The battle was the first clear Allied convoy victory.[61]. The. Shipping losses were high, but manageable. 19-20 June 1944.Japan attempts to stop the UNS from advancing in the pacific but were annihilated and the majority of the Japanese aircraft were destroyed in the "Great Marianas Turkey Shoot". Eighty percent of the Admiralty messages from March, 1942 to June 1943 were read by the Germans. Early in the war, Dnitz submitted a memorandum to Grand Admiral Erich Raeder, the German navy's Commander-in-Chief, in which he estimated effective submarine warfare could bring Britain to its knees because of the country's dependence on overseas commerce. To effectively disable a submarine, a depth charge had to explode within about 20ft (6.1m).

[28] Similar problems plagued the US Navy's Mark 14 torpedo, but it ignored the reports of German problems.[29]. Over the next two years many U-boats were sunk, usually with all hands. Larger numbers of escorts became available, both as a result of American building programmes and the release of escorts committed to the North African landings during November and December 1942. The last actions in American waters took place on May 56, 1945, which saw the sinking of the steamer Black Point and the destruction of U-853 and U-881 in separate incidents.

Henceforth the U.S. would either have to recall its ships from the ocean or enforce its right to the free use of the seas."[50]. The Italian submarines had been designed to operate in a different way than U-boats, and they had a number of flaws that needed to be corrected (for example huge conning towers, slow speed when surfaced, lack of modern torpedo fire control), which meant that they were ill-suited for convoy attacks, and performed better when hunting down isolated merchantmen on distant seas, taking advantage of their superior range and living standards. The principal belligerents were the Axis powersGermany, Italy, and Japanand the AlliesFrance, Great Britain, the United States, the Soviet Union, and, to a lesser extent, China.

Gnter Hessler, Admiral Dnitz's son-in-law and first staff officer at U-boat Command, said: 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. 24 May 1943. There were disadvantages to the early versions of this system. Dead Japanese soldiers cover the beach at Tanapag, on Saipan Island, in the Marianas, on July 14, 1944, after their last desperate attack on the U.S. Marines who invaded the . The convoys were essential to the British and Soviet war efforts (read more about the Arctic convoys to the USSR in "Convoy is to Scatter" and The Ordeal of PQ-17 .

War had come too early for the German naval expansion project Plan Z. Battleships powerful enough to destroy any convoy escort, with escorts able to annihilate the convoy, were never achieved. One of the more important developments was ship-borne direction-finding radio equipment, known as HF/DF (high-frequency direction-finding, or Huff-Duff), which started to be fitted to escorts from February 1942. An escort could then run in the direction of the signal and attack the U-boat, or at least force it to submerge (causing it to lose contact), which might prevent an attack on the convoy. On June 13, 1941, Commodore Leonard Murray, Royal Canadian Navy, assumed his post as Commodore Commanding Newfoundland Escort Force, under the overall authority of the Commander-in-Chief, Western Approaches, at Liverpool.
