How much would cost to build an atomic bomb from scratch?
That's quite a range. Do you know which country has spent the most money on building atomic bombs?
Yes, the United States has spent the most money on building atomic bombs. It is estimated that the Manhattan Project, which was responsible for the development and production of the first atomic bomb during World War II, cost around $2 billion at the time, which is equivalent to about $27 billion today.
