Why were American ships trying to maintain control of the Atlantic Ocean during WW2?

American ships trying to maintain control of the Atlantic Ocean during WW2 because it was a route of trade and sending weapons to England.

Explanation:

During world war 2, American ships want to take control of the Atlantic ocean because of several reasons. The first reason is that from this sea route trade and transportation of weapons and goods was done while the second reason is that to block trade of Germans with their allies. Through these sea routes, American send their soldiers and weapons to the front line against Germany. So it was necessary to take control of Atlantic Ocean.

During World War II both the Allies and the Axis Powers fought for control of the Atlantic Ocean. The Allies which comprised of the United States, Great Britain and Soviet Union thought to use the Atlantic to supply more items such as weapons, food etc to Great Britain and the Soviet Union in their fight against Germany and Italy. The Axis Powers wanted to stop them which led to the fight for control of the Atlantic Ocean. This war was called the Battle of the Atlantic and it lasted from September 3, 1939 to May 8, 1945.
