All existing nuclear weapons derive some of their explosive energy from nuclear fission reactions. Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs (abbreviated as A-bombs).
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively. The bombings killed between 150,000 and 246,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict.

The first atomic bombs dropped on Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, were large, custom-made devices, requiring highly trained personnel for their arming and deployment.
19 lis 2024 · Fission weapons are commonly referred to as atomic bombs. Fusion weapons are also referred to as thermonuclear bombs or, more commonly, hydrogen bombs; they are usually defined as nuclear weapons in which at least a portion of the energy is released by nuclear fusion.
There are two types of nuclear weapons: fission weapons (also called atomic bombs or A-Bombs) and fusion weapons (also called hydrogen bombs, H-Bombs, or thermonuclear weapons). They make energy for the nuclear explosion in different ways.
