For 3 years, scientists in secret cities around the U.S. had been in a race against time to complete the world’s first atomic weapon. And in July of 1945, the very first plutonium bomb was ready. Constructing “The Gadget” as it was called, had taken 2 billion dollars and the collective work of 400,000 people. It was ready to be tested. And it needed to work.
