World War II: Technology

Involvement of United States in World War II: Technology

American military technologies developed during World War II became more advanced and specialized as the war progressed. The technologies produced ranged in complexity from relatively simple items such as small arms and armored vehicles, including tanks, to more complex items such as the atomic bomb. The latter, produced under the secretive Manhattan Project, proved to be an incredibly powerful weapon that revolutionized warfare and was used to end the war. Many war technology were invented during the World War II. One of them is Radar technology.

RADAR

Radar was secretly developed by several nations in the period before and during World War II. The term Radar was coined by United States

At Pearl Harbor on December 7, 1941 torpedo planes and Bombers from Japanese aircraft carrier sank 8 battleship, leaving the US Pacific Fleet too weak to launch any major offensive operation for months. Two days later, Japanese paid a series of ruinous visit to Philippines destroying US planes at Philippine airfield. For practical purpose, the American submarines were now the only US weapon capable for carrying the war to japan. In Entire pacific, there were just 55 boats assigned to two uncoordinated submarines commands. The Sealion became the first US submarine casualty of war during Japanese attack on Cavite. The submarine saw themselves as scouting outriders in the early stages of combat and in hurly-burly of decisive surface battle, as underwater attack vessel dealing death and dismay to enemy. Despite a succession of improved submarine models, American designer were unable to bring into existence a boat that could travel with the surface fleet for greater distance at necessary avg. speed of 17 knots. As a result, they were relegated to coastal defense of USA mainland, Hawaii, Panama, and the

Sachs to the white house in October 1939, president authorized and appointed an advisory committee on Uranium. The committee had accomplished little and was moribund when president ordered it reconstituted as a sub Committee of Nation Defense Research Committee (NDRC), whose establishment he announced in June 1940. The nuclear research was called uranium section (S-I) of NDRC. The A-bomb may have helped end the war, but it was far more significant for the future, not least because the Manhattan Project became the model for scientific research harnessed for military purposes. It stands as a remarkable accomplishment, industrial and technological as well as scientific. The initial discovery of nuclear fission became public early in 1939. The demonstration of a sustained chain reaction came on 2 December 1942. By mid-1942 the army took control of the project as it shifted from research and development to engineering, procurement, construction, and production. In three years the Manhattan Project designed, built, and operated an industrial plant that rivaled in scale the entire prewar American automobile
