Summarize How did the scientific and technological

Answer 1

Answer:

In the USA, the main attention was paid to the development of aviation and the navy. By the end of the war, the US Air Force became the largest in the world. In the initial period of the war, Curtiss P-40 prevailed in fighter aircraft, which were then gradually replaced by the P-51 Mustang, P-47 Thunderbolt, and P-38 Lightning. B-17 Flying Fortress and B-24 Liberator were used as strategic bombers, and B-29 Superfortress was developed for strategic bombing of Japan. Armored vehicles in the United States received much less attention. Before the war, the U.S. Army was armed with mostly light M2 tanks. In the initial period of the war, they were replaced by M3 Stuart light tanks and the hastily designed M3 Lee medium tanks.

In 1943, the Los Alamos National Laboratory, the U.S. secret nuclear research center, began operations in the United States. During the war years, an atomic bomb was made that the US used against Japan in 1945.
