How did the Allies win control of the Atlantic Ocean between 1941 to 1943?

Answer 1

By closing the 'air gap'. That is the parts of the ocean that was not able to be covered by air recconaisance. Submarines were vulnerable to detection & attack from the air and long range aircraft such as Catalina & Liberator made a huge difference. But they needed bases to fly from. The denial of such a base in the Irish Republic cost Britain dear for many months. Also, of course Asdic & better depth charges & increased range & effective escort vessels made a difference as time went on. In the beginning of the Battle of the Atlantic the Germans were sinking ships faster than they could be built. Many, many ships were sunk & huge amounts of stores & war material were lost. Britain was, for a time, in a very perilous position both to submarine & surface ships sinking unarmed merchant ships.

Answer 2

They regained full control only near the end of the war (1944) when Italy had surrendered, the German Luftwaffe no longer had the means to pose a threat to Allied shipping and Greece had been liberated from German occupation.

Answer 3

The Allies responded by organizing their cargo ships into convoys. The convoys were escorted across the Atlantic by destroyers equipped with sonar for detecting submarines underwater. They were also accompanied by airplanes that used radar to spot U-boats on the ocean's surface. At the same time, the United States launched a crash shipbuilding program.

Answer 4

The Allies won control by building many ships specifically to hunt and kill U-Boats, and by patrolling further out into the Atlantic with powerful aircraft. The convoy system with many corvette escorts helped a great deal too.

Answer 5

The Atlantic was a merchantman's war (supply ships). The allies won it by eliminating the German submarines (aka U-Boats) that were attacking the merchant vessels.

Answer 6

The Allies won control of the Atlantic by defeating the U-Boats. The built many corvettes and long range bombers to do this.
