Although North Korea adhered to its self­-declared moratorium on the testing of nuclear weapons and long­-range ballistic missiles in 2019, during the year it conducted multiple flight tests of shorter-range ballistic missiles, including several new types of system. 1112 16th Street NW More warheads are in production. The decrease in the overall number of nuclear weapons in the world in 2019 was largely due to the dismantlement of retired nuclear weapons by Russia and the USA—which together still possess over 90 per cent of global nuclear weapons. Details are scarce, but we estimate that Russia is dismantling 200-300 retired warheads per year. Several thousand retired non-strategic warheads are awaiting dismantlement.

Unlike those “fixed” publications, this web page is updated continuously as new information becomes available, so estimates may differ. The first nuclear weapon was detonated by the United States of America in a war against Japan. Total figures include the highest estimate when a range is given. In July 2017, it looked as though the world was a step closer to becoming nuclear weapon free when more than 100 countries endorsed a UN treaty to ban them altogether. Ever since the Nuclear Non-Proliferation Treaty, there has been a cap of sorts that determines how many countries are allowed to access, house, and utilize nuclear weapons. As of calculations performed in 2017, it has been determined that there is an estimated number of 9,220 nuclear weapons worldwide. Uncertainty persists about how many nuclear devices North Korea has assembled. The bombs get their energy from either splitting atoms or joining the tiny particles inside the atoms together. This was due in part to the US administration’s insistence that China must join any future nuclear arms reduction talks—something that China has categorically ruled out. First tested: 1945 Phone: 202.546.3300. Figures for North Korea are highly uncertain and are not included in total figures.

But they've only ever been used twice in history - against Japan in 1945 during World War Two where they caused huge devastation and enormous loss of life. The nuclear arsenals of the other nuclear-armed states are considerably smaller but all these states are either developing or deploying new weapon systems or have announced their intention to do so. * ‘Deployed warheads’ refers to warheads placed on missiles or located on bases with operational forces. France. Despite progress in reducing Cold War nuclear arsenals, the world’s combined inventory of nuclear warheads remains at a very high level: roughly 13,410 warheads as of early-2020. a Warheads in the “military stockpile” are defined as warheads in the custody of the military and earmarked for use by military forces.

Kristensen, Associate Senior Fellow with SIPRI’s Nuclear Disarmament, Arms Control and Non-proliferation Programme and Director of the Nuclear Information Project at the Federation of American Scientists (FAS). Accordingly, while the estimate for the United States is based on “real” numbers, the estimates for several of the other nuclear weapon states are highly uncertain. The countries that once did but no longer do have nuclear weapons at their disposal include South Africa, Belarus, Ukraine, and Kazakhstan. Nuclear warhead reductions continue despite growing tensions. Warhead loadings on some submarines missiles have been reduced to increase targeting flexibility.

Sweden Four major SIPRI Yearbook 2020 data sets were pre-launched in 2019–20: the top 100 arms-producing companies (December 2019), international arms transfers (March 2020), world military expenditure (April 2020) and trends in multilateral peace operations (May 2020). Countries like India, Pakistan, and Israel refused to sign treaties presented to them regarding nuclear weapons, and yet, they still have nuclear arsenals on their person.
