India | India's Nuclear Weapon Program | India was the seventh country to develop nuclear weapons. As of 2026, India is estimated to possess 190 nuclear weapons. India operates a nuclear triad, consisting of ballistic missiles from short to intercontinental range, nuclear armed fighter-bombers, and submarine-launched ballistic missiles. India maintains a no first use nuclear policy and credible minimum deterrence doctrine. Its no first use is qualified in that while India states it generally will not use nuclear weapons first, it may do so in the event of a major attack. Israel | Isreals's Nuclear Weapon Program | Israel is widely believed to possess a substantial arsenal of nuclear weapons and missiles, estimated at 75–130 and 100–200 warheads, but refuses officially to confirm or deny whether it has a nuclear weapon program. Unconfirmed rumors have hinted at tactical nuclear artillery shells, light fission bombs and missile warheads, and perhaps thermonuclear missile warheads. Pakistan | Pakistan's Nuclear Weapon Program | As of 2026, Pakistan is believed to possess about 170 nuclear weapon devices and the specifications of these weapon systems and their productions are highly classified. Pakistan’s nuclear doctrine focuses explicitly on countering India's conventional military superiority. Pakistan explicitly rejects a "no first-use" policy, reserving the right to use nuclear weapons first if it feels its national existence is threatened. Pakistan is actively expanding its delivery triad. North Korea | North Korea's Nuclear Weapon Program | North Korea claims to possess nuclear weapons, however, the specifications of its systems are not public. It is estimated to have 6–18 low yield nuclear weapons. 03/09/2017, North Korea conducted an underground thermonuclear test which had an estimated yield of 100kt to 250kt. 24/03/2023, North Korea unveiled the Hwasan-31 tactical nuclear bomb with at least 10 warheads shown, each measuring an estimated 40 to 50 centimeters in diameter and 1 meter in length. Hwasong-11A (KN-23) and KN-25 ballistic missiles are capable of carrying it. South Africa | South Africa's Nuclear Weapon Program | South Africa built six or seven gun-type weapons. All constructed weapons were verified by International Atomic Energy Agency and other international observers to have been dismantled along with the complete weapons program, although they still possess the highly enriched uranium.
