government began funding its own atomic weapons development program, which came under the joint responsibility of the Office of Scientific Research and Development and the War Department after the U.S. entry into World War II. The atomic bomb was created during World War II during the Manhattan Project. The scientists that worked on the program worked on producing the key materials for nuclear fission for the elements uranium-235 and plutonium (Pu-239). On July 16, 1945, the Manhattan Project held its very first successful test of an atomic device, which was a nuclear bomb, at the Trinity test site in Alamogordo, New Mexico.By the time the Trinity test took place, the Allied powers had already defeated Germany in Europe. Despite Germany surrendering to the Allied Powers, Japan vowed to fight to the bitter endJapan vowed to fight until the bitter end in the Pacific, despite clear evidence that they had little to no chance of winning. The Japanese militaristic government rejected the Allied Powers demand for surrender that was set in the Potsdam Declaration, which threatened the Japanese government with “prompt and utter destruction” if they refused to surrender immediately to the Allied Powers. Hiroshima, which was selected as the first main target, was a manufacturing center with 350,000 people located in the city and was about 500 miles from Tokyo. After arriving at the U.S. base on the Pacific island of Tinian, the more than 9,000-pound uranium-235 bomb was loaded aboard a modified B-29 bomber christened Enola Gay. The plane dropped the bomb, which was known by many as “Little Boy,” was dropped by parachute at 8:15 in the morning, and it exploded 2,000 feet above Hiroshima in a blast equal to 12-15,000 tons of TNT, and it destroyed roughly five square miles of the city. The atomic bombing of Hiroshima and the devastation still did not convince the Japanese government to surrender to the Allied
