Air warfare during World War II was a key element in the strategies and tactics of the battles that the Allied Forces and the Axis Powers fought. The United States Air Force and Great Britain army deployed air strategies for bombing raids over important targets in Germany such as its main cities. Air superiority was an important advantage to win the war in the air.
The other options of the question were, a) they carried out countless bombing raids over German cities, b) they sank ships carrying supplies to Britain, and d) they ferried retreating troops between Britain and Europe.
Answer: A. They carried out countless bombing raids on targets in Germany
Explanation:
Although World War II began in 1939, the U.S. only became directly involved when the attack on Pearl Harbor happened (December 7, 1941). However, developments required to provide military air support for Britain against the Nazis had started a long time before that.
By January 1942, with the U.S. working together with Britain's Royal Air Force, the Allied forces established the VIII Bomber Command to manage the air offensive against Germany.
