When and where were the only times nuclear weapons were used in combat?
On August 6, 1945, a uranium-based weapon, Little Boy, was detonated above the Japanese city of Hiroshima, and three days later, a plutonium-based weapon, Fat Man, was detonated above the Japanese city of Nagasaki. To date, Hiroshima and Nagasaki remain the only two instances of nuclear weapons being used in combat.
Which country has been the only one to have a nuclear weapon used against it during wartime?

What would a nuclear winter be like?
The nuclear winter scenario assumes that 100 or more city firestorms are ignited by nuclear explosions, and that the firestorms lift large amounts of sooty smoke into the upper troposphere and lower stratosphere by the movement offered by the pyrocumulonimbus clouds that form during a firestorm.
What was the only time nuclear weapons were used in combat?
During the final stages of World War II in 1945, the United States conducted atomic raids on the Japanese cities of Hiroshima and Nagasaki, the first on August 6, 1945, and the second on August 9, 1945. These two events were the only times nuclear weapons have been used in combat. For six months…
What is the difference between nuclear warfare and conventional warfare?
Nuclear warfare. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological warfare result. A major nuclear exchange would have long-term effects, primarily from the fallout released,…
How active was the Cold War in developing nuclear weapons?
If we consider the number of nuclear weapons tests, we can see that the Cold War was a very active period of nuclear weapons development. Although nuclear weapons were only ever used in warfare during the Second World War, there have been over 2000 nuclear weapons tests since then.
Are smaller nuclear warheads more dangerous?
The existence and deployment of small, low-yield tactical nuclear warheads could be a dangerous encouragement to forward-basing and pre-emptive nuclear warfare, as nuclear weapons with destructive yields of 10 tons of TNT (e.g., the W54 warhead design) might be used more willingly at times of crisis than warheads with yields of 100 kilotons.
