I have been curious to know some authentic information on Nuclear Weapon ownership State wise, Quantity wise.
Read On. Seems to be authentic.
The nuclear-weapon states (NWS) are the five states—China, France, Russia, United Kingdom, and the United States—officially recognized as possessing nuclear weapons by the NPT. Although the treaty legitimizes these states’ nuclear arsenals, it also establishes that they are not supposed to build and maintain such weapons in perpetuity. Article VI of the treaty holds that each state-party is to “pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament.” In 2000, the five NWS committed themselves to an “unequivocal undertaking…to accomplish the total elimination of their nuclear arsenals.” But for now, the five continue to retain the bulk of their nuclear forces. Because of the secretive nature with which most governments treat information about their nuclear arsenals, most of the figures below are best estimates of each nuclear-weapon state’s nuclear holdings, including both strategic warheads and lower-yield devices referred to as tactical weapons. Russia and the United States also retain thousands of retired warheads planned for dismantlement, not included here.
China: About 240 total warheads.
France: Fewer than 300 operational warheads.
Russia: Approximately 1,499 deployed strategic warheads . The Federation of American Scientists estimates Russia has another 1,022 nondeployed strategic warheads and approximately 2,000 tactical nuclear warheads. Additional thousands are awaiting dismantlement.
United Kingdom: Fewer than 160 deployed strategic warheads, total stockpile of up to 225.
United States: Approximately 5,113 nuclear warheads , including tactical, strategic, and nondeployed weapons. According to the latest official New START declaration, the United States deploys 1,722 strategic nuclear warheads on 806 deployed ICBMs, SLBMs, and strategic bombers . The Federation of American Scientists estimates that the United States’ nondeployed strategic arsenal is approximately 2,800 warheads and the U.S. tactical nuclear arsenal numbers 500 warheads. Additional warheads are retired and await dismantlement.
Non-NPT Nuclear Weapons Possessors:
Three states—India, Israel, and Pakistan—never joined the NPT and are known to possess nuclear weapons. Claiming its nuclear program was for peaceful purposes, India first tested a nuclear explosive device in 1974. That test spurred Pakistan to ramp up work on its secret nuclear weapons program. India and Pakistan both publicly demonstrated their nuclear weapon capabilities with a round of tit-for-tat nuclear tests in May 1998. Israel has not publicly conducted a nuclear test, does not admit to or deny having nuclear weapons, and states that it will not be the first to introduce nuclear weapons in the Middle East. Nevertheless, Israel is universally believed to possess nuclear arms. The following arsenal estimates are based on the amount of fissile material—highly enriched uranium and plutonium—that each of the states is estimated to have produced. Fissile material is the key element for making nuclear weapons. India and Israel are believed to use plutonium in their weapons, while Pakistan is thought to use highly enriched uranium.
India: Up to 100 nuclear warheads.
Israel: Between 75 to 200 nuclear warheads.
Pakistan: Between 90 to 110 nuclear warheads.
States of Immediate Proliferation Concern:
Iran is pursuing a uranium-enrichment program and other projects that could provide it with the capability to produce bomb-grade fissile material and develop nuclear weapons within the next several years. In contrast, North Korea has the material to produce a small number of nuclear weapons, announced its withdrawal from the NPT, and tested nuclear devices. Uncertainty persists about how many additional nuclear devices North Korea has assembled beyond those it has tested. In September 2005, Pyongyang “committed to abandoning all nuclear weapons and existing nuclear programs.”
Iran: No known weapons or sufficient fissile material stockpiles to build weapons. However, the International Atomic Energy Agency (IAEA), the institution charged with verifying that states are not illicitly building nuclear weapons, concluded in 2003 that Iran had undertaken covert nuclear activities to establish the capacity to indigenously produce fissile material. The IAEA is continuing its investigation and monitoring of Tehran’s nuclear program.
North Korea: Has separated enough plutonium for roughly 10 nuclear warheads.
Syria: In September 2007, Israel conducted an airstrike on what U.S. officials have alleged was the construction site of a nuclear research reactor similar to North Korea’s Yongbyon reactor. Intelligence officials briefed members of congress on the airstrike eight months later in April 2008, discussing the evidence leading to their judgment that the site was an undeclared nuclear reactor. While the extent of Syrian-North Korean nuclear cooperation is unclear, it is believed to have begun in 1997. Subsequent IAEA investigations into the U.S. claims uncovered traces of undeclared man-made uranium particles at both the site of the destroyed facility and Syria’s declared research reactor. Syria has failed to provide adequate cooperation to the IAEA in order to clarify the nature of the destroyed facility and procurement efforts that could be related to a nuclear program.
States That Had Nuclear Weapons or Nuclear Weapons Programs at One Time:
Belarus, Kazakhstan, and Ukraine inherited nuclear weapons following the Soviet Union’s 1991 collapse, but returned them to Russia and joined the NPT as non-nuclear-weapon states. South Africa secretly developed and dismantled a small number of nuclear warheads and also joined the NPT in 1991. Iraq had an active nuclear weapons program prior to the 1991 Persian Gulf War, but was forced to verifiably dismantle it under the supervision of UN inspectors. The U.S.-led March 2003 invasion of Iraq and subsequent capture of Iraqi leader Saddam Hussein definitively ended his regime’s pursuit of nuclear weapons. Libya voluntarily renounced its secret nuclear weapons efforts in December 2003. Argentina, Brazil, South Korea, and Taiwan also shelved nuclear weapons programs.
1. On Oct. 3, 2012 the U.S. State Department issued the latest fact sheet on its data exchange with Russia under New START, sharing the numbers of deployed nuclear warheads and New START-accountable delivery systems held by each country.
2. On May 3, 2010, the United States Department of Defense released for the first time the total number of nuclear warheads (5,113) in the U.S. stockpile. The Defense Department includes in this stockpile active warheads which are operational and deployed or ready to be deployed, and inactive warheads which are maintained “in a non-operational status, and have their tritium bottle removed.”
