Impossible to say, but it definitely happened in China not long after they perfected the formula for black powder. The Chinese first used black powder to make various types of fireworks, including firecrackers. But eventually adapted black powder based fireworks technology to warfare by scaling upward.
The US .
The atomic bomb was not invented by a team, it was invented by Leo Szilard in 1933 while crossing a London street. However it took a team to build the first ones, that was called the Manhattan Engineering District.
Since Leo Szilard invented the atomic bomb in 1933 in London and patented it in 1934, I would have to say it was invented in England. But he was unable to build it at the time.It took another 12 years and a gigantic investment in industrial infrastructure before the US was able to build the first ones based on this patent.
the atomic bomb was not discovered, it was invented then built.
the V1 flying bomb was invented to bomb England in world war 2 and first flew in 1942 so that meaks it about 58 years old. if this is wrong please correct.
The first bomb was invented in 1281 A.D.
The first time bomb was invented at Yale University. It was invented by David Bushnell and used in the first submarine used in combat.
1775
The atomic bomb was not invented by a project, it was invented by Leo Szilard in 1933.However the Manhattan Project built the first ones in 1945.
He first invented the stink bomb
The hydrogen bomb was invented by a team of American scientists led by Edward Teller. The first successful test of the hydrogen bomb was conducted by the United States in 1952.
1850's
The US .
The Hydrogen Bomb .
Leo Szilard invented the fission bomb. Edward Teller invented the fusion bomb. Both were from Hungary.
Unknown for certain, but it was probably the Chinese as they invented black powder.
After USSR (mostly in asia), China.
