Despite these successes, the Italian intervention was not favourably regarded by Dnitz, who characterised Italians as "inadequately disciplined" and "unable to remain calm in the face of the enemy". Therefore, a few large convoys with apparently few escorts were safer than many small convoys with a higher ratio of escorts to merchantmen. [84] On 22 May 1942, the first Brazilian attack (although unsuccessful) was carried out by Brazilian Air Force aircraft on the Italian submarineBarbarigo. Not only would there be sufficient numbers of escorts to securely protect convoys, they could also form hunter-killer groups (often centered on escort carriers) to aggressively hunt U-boats.

While this was an embarrassment for the British, it was the end of the German surface threat in the Atlantic. Moreover, reduced frequency also reduced the chances of detection, as fewer large convoys could carry the same amount of cargo, while large convoys take longer to assemble. British Prime Minister Winston Churchill later wrote "The only thing that really frightened me during the war was the U-boat peril.

Although CAM ships and their Hurricanes did not down a great number of enemy aircraft, such aircraft were mostly Fw 200 Condors that would often shadow the convoy out of range of the convoy's guns, reporting back the convoy's course and position so that U-boats could then be directed on to the convoy. Since early ASDIC equipment was poor at determining depth, it was usual to vary the depth settings on part of the pattern. 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.

The Allies invade Normandy on 5 different beaches with paratroopers flanking the German forces. Due to ongoing friction between the Luftwaffe and Kriegsmarine, the primary source of convoy sightings was the U-boats themselves.

Two million gross tons of merchant shipping13% percent of the fleet available to the Britishwere under repair and unavailable, which had the same effect in slowing down cross-Atlantic supplies.[37]. The Metox set beeped at the pulse rate of the hunting aircraft's radar, approximately once per second. The . 3, allowing the Germans to estimate where and when convoys could be expected. More importantly, early ASDIC sets could not look directly down, so the operator lost contact on the U-boat during the final stages of the attack, a time when the submarine would certainly be manoeuvring rapidly. At a tactical level, new short-wave radar sets that could detect surfaced U-boats and were suitable for both small ships and aircraft began to arrive during 1941. 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. Should the U-boat dive, the aircraft would attack. For the first half of 1940, there were no German surface raiders in the Atlantic because the German Fleet had been concentrated for the invasion of Norway.

What was important about the liberation of France? This strategy was deeply flawed because a U-boat, with its tiny silhouette, was always likely to spot the surface warships and submerge long before it was sighted.

Running down the bearing of a HF/DF signal was also used by escort carriers (particularly USSBogue, operating south of the Azores), sending aircraft along the line of the bearing to force the submarine to submerge by strafing and then attack with depth charges or a FIDO homing torpedo. Immediate diving remained a U-boat's best survival tactic when encountering aircraft. As in 1941, help from Canadas expanding military came in a timely fashion in 1942 as Canadian naval and air forces filled the void left in the North Atlantic by the departure of U.S. forces to the Caribbean and Pacific. The belief that ASDIC had solved the submarine problem, the acute budgetary pressures of the Great Depression, and the pressing demands for many other types of rearmament meant little was spent on anti-submarine ships or weapons. So there was a time lag between the last fix obtained on the submarine and the warship reaching a point above that position. They found a enigma machine, which was used by the Germans to send messages which allowed them to track the U-boats movements. Instead of attacking the Allied convoys singly, U-boats were directed to work in wolf packs (Rudel) coordinated by radio. This eventually led to the "Destroyers for Bases Agreement" (effectively a sale but portrayed as a loan for political reasons), which operated in exchange for 99-year leases on certain British bases in Newfoundland, Bermuda and the West Indies, a financially advantageous bargain for the United States but militarily beneficial for Britain, since it effectively freed up British military assets to return to Europe.

Once in position, the crew studied the horizon through binoculars looking for masts or smoke, or used hydrophones to pick up propeller noises. German U-boats also operated in considerable force along the South Atlantic ship lanes to Asia and the Middle East. If an echo was detected, and if the operator identified it as a submarine, the escort would be pointed towards the target and would close at a moderate speed; the submarine's range and bearing would be plotted over time to determine course and speed as the attacker closed to within 1,000 yards (910m). 14 September 1942- 2 February 1943.

Allied convoys transporting military equipment and supplies. Improving spring weather by April, modern radar equipment, repenetration of the U-boat codes, new escort aircraft carriers, very-long-range patrol aircraft, and aggressive tactics had resulted in a major defeat of Germanys submarine fleet by May. The British, however, developed an oscilloscope-based indicator which instantly fixed the direction and its reciprocal the moment a radio operator touched his Morse key. They found a enigma machine, which was used by the Germans to send messages which allowed them to track the U-boats movements. 23 October-4 November 1942. Fought largely by reservists in .
