Nuclear weapons

Japan

Does not have nuclear weapons.

USA

The first country to develop and to military use nuclear warheads in the world. Everything started from the Manhattan project, a research that had one particular goal in focus – to develop and produce the first nuclear weapon. Americans were the first to wield such powerful weapon. Everything started in 1941, which is date of the beginning of Manhattan project. Since the end of the Second World War, United States became the leading country when it comes to possessing nuclear warheads and it lasted approximately to 1980s. We should also bear in mind that United States are also the only nation that ever used nuclear weapon in military conflict.

In 1960, the amount of warheads stored by Americans exceeded 30,000. However, it is worth to note that throughout the entire period of the so-called Cold War, USA managed to build approximately 70,000 nuclear warheads, what is more than all other countries with access to nuclear weapons combined. From the first test that happened in 1945 to this day, the USA conducted 1054 tests of atomic bombs. Still, as a result of introduced restrictions on the amount of warheads one state can possess, the current number has dropped to 6500 warheads. Noteworthy is also the fact that out of this number, United States deployed only 1600.
