This was the first atomic bomb.
Little boy and Fat man
inventing atom bomb to finish World War II.
competing with Soviet Union in technology
Albert Einstein sent a warning letter to Franklin Delano Roosevelt, the President of U.S.A. (1933-1945) on

Research and production took place at more than 30 sites in
USA., UK. and Canada.
It cost (the whole Manhattan project) 2 billion $ (that is ~
26 billion $
