Fat Man
What you see right here is known as “The Fat Man”, the nuclear bomb that was dropped on Nagasaki on August 9, 1945, which was during the last few weeks of WWII. This was the second of the two atomic weapons that have ever been used in history.
The first one was dropped in Hiroshima and it was called “The Little Boy”. These two bombs represented the definite end of WWII as well as a hallmark in the history of warfare.
