The People's Republic of Bulgaria had a significant missile arsenal, including 67 Scud (Elbrus), 50 Frog (Luna) and 24 Spider (Oka) ballistic missiles. [3] Since the Soviet Union planned to rapidly deploy its own nuclear weapons in Bulgaria in case a war broke out, the missiles were not armed with warheads, but only prepared to launch Soviet weapons. [3]
The SS-23 systems had conventional warheads plus a WMD launching capability. The nuclear missile launching pads and equipment were dismantled in 1991. The first missile brigade was created in 1961. [4] In 1994, the country bought 46 conventional warheads for its Scuds from Russia. [3] All Scud, Frog and Spider missiles were destroyed in 2002. Currently, Bulgaria operates a dozen Scarab launchers, but information over the exact number of missiles is classified. They are all armed with conventional warheads of 160 kg each.
Information over Bulgaria's chemical weapons is scarce. The only known chemical weapons production facility is located near Smyadovo, which now produces chemicals for civilian purposes. The country ratified the Chemical Weapons Convention in 1994 [5] and begun dismantlement in 2000. [6]
Bulgaria has signed and ratified the Biological Weapons Convention. [7] [8]
Bulgaria has never developed nuclear weapons, although some treaties with the Soviet Union guaranteed the deployment of Soviet warheads on Bulgarian territory in case of a war with NATO. Its R-400 missiles were nuclear-capable. [9] In the mid-1990s, journalist Goran Gotev investigated a testimony of an anonymous Soviet Army captain published in Komsomolskaya Pravda , who described in detail an alleged Soviet-Bulgarian nuclear weapons facility which hosted 70 warheads for tactical missiles. [10] The site consisted of "four three-storey apartment blocks, barracks, a cafeteria, a sports field, a social club, a store, and a plaza", and had 130 personnel. The unit was disbanded in 1989, the warheads were quickly shipped to Ukraine and all equipment, uniforms and photos that were present at the facility were destroyed. Another Russian Army official later denied the story. [10] However, in the 1980s four Bulgarian Air Force majors received training in the Soviet Union on releasing nuclear weapons from MiG-23BN aircraft. [11]
In 2001, the Bulgarian Foreign Ministry denied the "presence" of nuclear weapons in Bulgaria. [12]
The country has the potential to establish a military nuclear program, having a nuclear powerplant at Kozloduy with its own plutonium storage facility. [13] A nuclear research facility with a 200 kW pool-type reactor is in operation in Sofia. [14] The reactor of the facility produces some nuclear material, which is stored near Novi Khan. [15]
As part of its efforts to safeguard potentially weapons-usable atomic material, the United Nations nuclear watchdog assisted Bulgaria with the removal of highly enriched uranium stored at the shut-down research reactor in Sofia. The substance, which was 36% enriched and took the form of fresh fuel, was airlifted in December 2003 to Russia, the original supplier, according to the International Atomic Energy Agency (IAEA). Agency safeguards inspectors monitored and verified the packaging of the fuel, which Russia said it would re-fabricate into low-enriched uranium. [1]
In December 2016, Bulgaria voted against an UN Resolution that urged member states to begin negotiations on the complete abolition of nuclear weapons. [16]
In April 2018, information appeared about Turkey's desire to remove US nuclear weapons from the territory of the country. After NATO's official statements about the desire to expand the military presence of the United States in Europe, [17] it became known that Bulgaria could become a new location for nuclear weapons from Turkey. [18]
The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.
North Korea has a military nuclear weapons program and, as of early 2020, is estimated to have an arsenal of approximately 30 to 40 nuclear weapons and sufficient production of fissile material for six to seven nuclear weapons per year. North Korea has also stockpiled a significant quantity of chemical and biological weapons. In 2003, North Korea withdrew from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Since 2006, the country has conducted six nuclear tests at increasing levels of expertise, prompting the imposition of sanctions.
The Intermediate-Range Nuclear Forces Treaty was an arms control treaty between the United States and the Soviet Union. US President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev signed the treaty on 8 December 1987. The US Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988.
The Russian Federation is known to possess or have possessed three types of weapons of mass destruction: nuclear weapons, biological weapons, and chemical weapons. It is one of the five nuclear-weapon states recognized under the Treaty on the Non-Proliferation of Nuclear Weapons.
The United States is known to have possessed three types of weapons of mass destruction: nuclear weapons, chemical weapons, and biological weapons. The U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II. It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project". The United States pioneered the development of both the nuclear fission and hydrogen bombs. It was the world's first and only nuclear power for four years, from 1945 until 1949, when the Soviet Union produced its own nuclear weapon. The United States has the second-largest number of nuclear weapons in the world, after the Russian Federation.
The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1967 at Lop Nur. Tests continued until 1996, when the country signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT), but did not ratify it. China acceded to the Biological Weapons Convention (BWC) in 1984 and ratified the Chemical Weapons Convention (CWC) in 1997.
Canada has not officially maintained and possessed weapons of mass destruction since 1984 and, as of 1998, has signed treaties repudiating possession of them. Canada ratified the Geneva Protocol in 1930 and the Nuclear Non-proliferation Treaty in 1970.
As the collapse of the Soviet Union appeared imminent, the United States and their NATO allies grew concerned of the risk of nuclear weapons held in the Soviet republics falling into enemy hands. The Cooperative Threat Reduction (CTR) program was initiated by the Nunn–Lugar Act, which was authored and cosponsored by Sens. Sam Nunn (D-GA) and Richard Lugar (R-IN). According to the CTR website, the purpose of the CTR Program was originally "to secure and dismantle weapons of mass destruction and their associated infrastructure in former Soviet Union states." As the peace dividend grew old, an alternative 2009 explanation of the program was "to secure and dismantle weapons of mass destruction in states of the former Soviet Union and beyond". The CTR program funds have been disbursed since 1997 by the Defense Threat Reduction Agency (DTRA).
Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built.
From the 1960s to the 1990s, South Africa pursued research into weapons of mass destruction, including nuclear, biological, and chemical weapons under the apartheid government. South Africa’s nuclear weapons doctrine was designed for political leverage rather than actual battlefield use, specifically to induce the United States of America to intervene in any regional conflicts between South Africa and the Soviet Union or its proxies. To achieve a minimum credible deterrence, a total of six nuclear weapons were covertly assembled by the late 1980s.
Poland is not known or believed to possess weapons of mass destruction. During the Cold War, Soviet nuclear warheads were stockpiled in Poland and designated to deploy within the Polish People's Army. Poland was also working with Russia to help eliminate the large stockpiles of chemical and biological weapons developed by the Warsaw Pact countries. Poland ratified the Geneva Protocol on 4 February 1929.
The OTR-23 Oka was a mobile theatre ballistic missile deployed by the Soviet Union near the end of the Cold War to replace the obsolete SS-1C 'Scud B'. It carried the GRAU index 9K714 and was assigned the NATO reporting name SS-23 Spider. The introduction of the Oka significantly strengthened Soviet theatre nuclear capabilities as its range and accuracy allowed it not only to strike hardened NATO targets such as airfields, nuclear delivery systems, and command centers, but moving targets as well. It also had a fast reaction time, being able to fire in approximately five minutes, and was nearly impossible to intercept, thereby allowing it to penetrate defenses.
Saudi Arabia is not known to have a nuclear weapons program. From an official and public standpoint, Saudi Arabia has been an opponent of nuclear weapons in the Middle East, having signed the Treaty on the Non-Proliferation of Nuclear Weapons, and is a member of the coalition of countries demanding a Nuclear-weapon-free zone in the Middle East. Studies of nuclear proliferation have not identified Saudi Arabia as a country of concern. Nuclear technology company IP3 International was formed in June 2016 to transfer nuclear technology from the United States to Saudi Arabia.
The State of Israel is widely believed to possess nuclear weapons. Estimates of Israel's stockpile range between 80 and 400 nuclear warheads, and the country is believed to possess the ability to deliver them in several methods, including by aircraft, as submarine-launched cruise missiles, and via the Jericho series of intermediate to intercontinental range ballistic missiles. Its first deliverable nuclear weapon is thought to have been completed in late 1966 or early 1967; which would make it the sixth country in the world to have developed them.
Libya pursued programs to develop or acquire weapons of mass destruction from when Muammar Gaddafi seized control of Libya in 1969 until he announced on 19 December 2003 that Libya would voluntarily eliminate all materials, equipment and programs that could lead to internationally proscribed weapons. This included weapons of mass destruction and long-range ballistic missiles.
This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion. In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons. The availability of intelligence on recent advancements in nuclear weapons of several major countries is limited because of the classification of technical knowledge of nuclear weapons development.
In 2009, it was reported that Myanmar was suspected to have initiated a nuclear weapons program. If such a program does exist, Burma's technical and financial limitations may make it difficult for the program to succeed. The United States expressed concern in 2011 about potential violations of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), though by 2012 these concerns had been "partially allayed".
The Siberian Chemical Combine was established in 1953 in Tomsk-7 now known as Seversk, in the Tomsk Region as a single complex of the nuclear technological cycle for the creation of nuclear weapons components based on fissile materials. It is a subsidiary of TVEL.
The Republic of Kazakhstan, once a republic of the Soviet Union, was a primary venue for Soviet nuclear weapon testing from 1949 until 1989. Following the collapse of the Union of Soviet Socialist Republics (USSR) in 1991, Kazakhstan became the fourth-largest nuclear power in the world and hosted a considerably large weapon support infrastructure due to its reliance on the Soviet nuclear program as a means to develop its own local economy. Besides the nuclear program, Kazakhstan was also a prominent site of Soviet programs of biological and chemical weapons.
The Es-Salamresearch reactor, also known as the Aïn Oussara nuclear reactor is a nuclear research reactor in Algeria. The reactor can produce 15 megawatts-thermal and its primary uses are radiopharmaceutical production, neutron activation analysis, neutron radiography, and training. The reactor was supplied by China and built in the region of Aïn Oussera, nearly due south of the capital city of Algiers. It reached criticality in February 1992 and began operation in late 1993.
