In 1939 the Manhattan Project was started. The Manhattan project eventually gave us the precedents to the incredible and terrifying weapon known commonly as "a nuke" or "a nuclear bomb"
During the Manhattan Project a bomb was detonated in the Arizona deserts. That bomb is said to have started the nuclear weaponry phase. Was there an official name for that bomb, aside from "the Trinity test"? if so what was the name of the bomb. (similar to Little-boy and Fatman dropped on Nagasaki and Hiroshima)
