According to the Arms Control Association, the world's nuclear states possess a total of 13,080 nuclear warheads.
The following is a brief overview of the stockpiles of nuclear weapons in the countries that possess them:
The US Department of Defense estimated that there will be at least 200 nuclear warheads in 2020, but it expects this number to double in the next decade, to reach 700 launchable nuclear warheads by 2027 and 1,000 warheads by 2030.
270 nuclear warheads.
According to the Nuclear Weapons Reduction Treaty, Russia has 1,854 strategic warheads distributed among 527 intercontinental ballistic missiles and submarine-launched ballistic missiles, while the Federation of American Scientists estimates that the Russian military stockpile consists of about 4,497 nuclear warheads, with an additional 1,760 old warheads, in the framework of waiting disassemble it.
- United kingdom
It possesses about 225 strategic warheads, of which an estimated 120 are deployed and 105 are stored, as well as four nuclear-powered ballistic missile submarines.
- United State
According to the Nuclear Non-Proliferation Treaty, the United States of America possesses 1,389 strategic nuclear warheads on 665 intercontinental ballistic missiles, submarine-launched ballistic missiles and strategic bombers.
The United States also has an estimated 100 B-61 gravity nuclear bombs deployed at six NATO bases in Italy, Germany, Turkey, Belgium and the Netherlands, out of a total stockpile of 230 bombs.
On October 5 last year, the US State Department revealed the total number of warheads, confirming that it has 3,750 nuclear warheads, not including old (inactive) warheads and those expected to be dismantled.
Countries outside the Nuclear Non-Proliferation Treaty
As for the countries that possess nuclear weapons and have not joined the Treaty on the Non-Proliferation of Nuclear Weapons, and that possess nuclear weapons, they are India, Israel and Pakistan.
- India and Pakistan
India tested a nuclear device for the first time in 1974, prompting Pakistan to ramp up its secret nuclear weapons program, until the two countries conducted their first public nuclear tests in 1998.
India has about 156 nuclear warheads, while Pakistan has about 90 nuclear warheads, in addition to fissile material.
Israel denies possessing nuclear weapons, and asserts that it will not be the first to introduce such weapons into the Middle East, yet many believe that it possesses nuclear weapons without clear numbers on the matter. It is estimated that it possesses 165 nuclear warheads.
The most prominent countries that withdrew from the Treaty on the Non-Proliferation of Nuclear Weapons
The most notable country that withdrew from the treaty in 2003 was North Korea. And conducted numerous experiments on nuclear-capable ballistic missiles.
While the number of nuclear devices in North Korea's possession is ambiguous, estimates indicate that it has 40-50 warheads, in addition to 20-40 kg of plutonium and 250-500 kg of highly enriched uranium.
Prior to the nuclear agreement, Iran had continued its uranium enrichment programs and other projects related to the production of fissile material, but the nuclear agreement restricted Tehran's activity before the United States withdrew from it.
There are no known weapons or stockpiles of fissile material, but the IAEA said in 2015 that Iran had an organized nuclear weapons program prior to 2003.
As for Syria, Israel bombed a site in 2007 that it claimed was a base for building a nuclear reactor similar to the Yongbyon nuclear reactor in North Korea, amid belief that cooperation between North Korea and Syria in this field began in 1997.
Countries that have had or had nuclear weapons programs
Belarus, Kazakhstan, and Ukraine inherited nuclear weapons after the collapse of the Soviet Union, before handing them over to Russia and joining the Nuclear Non-Proliferation Treaty as non-nuclear-weapon states.
South Africa worked on developing a limited number of nuclear warheads, before dismantling them and joining the Nuclear Non-Proliferation Treaty. Brazil, South Korea and Taiwan suspended their programmes.
As for the Arab world, Iraq had a nuclear weapons program before the 1991 Gulf War, before it was dismantled under the supervision of the United Nations, according to the report. Libya voluntarily abandoned efforts to acquire nuclear weapons in 2003.
