After the Japanese bombed Pearl Harbor, we rapidly looked for a way to respond. The decision was to drop a 10,000 pound atomic bomb named "little boy" on the city of Hiroshima, Japan.
This nuclear weapon was a success and killed around 140,000 people. Eight days later, we dropped another bomb (code named "fat man") on the costal city of Nagasaki, Japan. It killed about 80,000 people (sources 2 and 9). This made us the first country to use a nuclear weapon in war. It was rumored that we possibly ignited the Cold War through this action (source 9). This was pretty much the ending to World War II. Without this kind of technology, we may have had a different response plan. There was a great amount of strategy used in World War II. Much of it was required to use the great weapons we had. One important thing technology helped developed was computer like devices to bypass Nazi Enigma codes (source 1). We also developed a nutrition program and conducted studies to identify research and other important data. Soldier's rations were carefully formulated in labs before being sent out. The D-Ration bar was widly used for emergency ration, as it provided soldiers with around 1,800 calories.It was small things like these that benefited us ( Source
