From the 1960s to the 1980s, South Africa pursued research into weapons of mass destruction, including nuclear, biological, and chemical weapons. Six nuclear weapons were assembled. With the anticipated changeover to a majority-elected government in the 1990s, the South African government dismantled all of its nuclear weapons, the first nation in the world which voluntarily gave up nuclear arms it had developed itself.

The country has been a signatory of the Biological Weapons Convention since 1975, the Nuclear Non-Proliferation Treaty since 1991, and the Chemical Weapons Convention since 1995.

South Africa developed a small finite deterrence arsenal of gun-type fission weapons in the 1980s. Six were constructed and another was under construction at the time the program ended. South Africa was able to mine uranium ore domestically, and used aerodynamic nozzle enrichment techniques to produce weapons-grade material. South Africa is suspected of having received technical assistance from various sources, including assistance from Israel in building its first nuclear device.^{[citation needed]} In 1969, a pair of South African scientists met with Sültan Mahmoud, a nuclear engineer, to hold discussion on enrichment technology and to learn the effective use of aerodynamic-jet nozzle process to enrich the fuel. However, it is unknown and unclear on how much knowledge was gained, and how much interaction was made between them.^{[citation needed]}

Testing the first device

The South African Atomic Energy Board (AEB) selected a test site in the Kalahari Desert at the Vastrap weapons range north of Upington. Two test shafts were completed in 1976 and 1977. One shaft was 385 metres deep, the other, 216 metres. In 1977, the AEB established its own high-security weapons research and development facilities at Pelindaba, and during that year the program was transferred from Somchem to Pelindaba. In mid-1977, the AEB produced a gun-type device—without a highly enriched uranium (HEU) core. Although the Y-Plant was operating, it had not yet produced enough weapons-grade uranium for a device. As has happened in programmes in other nations, the development of the devices had outpaced the production of the fissile material.

Atomic Energy Commission officials say that a "cold test" (a test without uranium-235) was planned for August 1977. An Armscor official who was not involved at the time said that the test would have been a fully instrumented underground test, with a dummy core. Its major purpose was to test the logistical plans for an actual detonation.

How that test was cancelled has been well publicised. Soviet intelligence detected test preparations and in early August alerted the United States; U.S. intelligence confirmed the existence of the test site with an overflight of a Lockheed SR-71 spy plane. On 28 August, the Washington Post quoted a U.S. official: "I'd say we were 99 percent certain that the construction was preparation for an atomic test."

The Soviet and Western governments were convinced that South Africa was preparing for a full-scale nuclear test. During the next two weeks in August, the Western nations pressed South Africa not to test. The French foreign minister warned on 22 August of "grave consequences" for French-South African relations. Although he did not elaborate, his statement implied that France was willing to cancel its contract to provide South Africa with the Koeberg nuclear power reactors.

In mid-1983 de Villiers said that when the test site was exposed, he ordered its immediate shutdown. The site was abandoned and the holes sealed. One of the shafts was temporarily reopened in 1988 in preparation for another test, which did not take place; the move was intended to strengthen South Africa's bargaining position during negotiations to end the war with Angola and Cuba.

Viable delivery

The warheads were originally configured to be delivered from one of several aircraft types then in service with the South African Air Force (SAAF), including the Canberra B12 and the Blackburn Buccaneer. Concerns about the vulnerability of the aircraft to the Cuban anti-aircraft defence network in Angola subsequently led the SADF investigate missile-based delivery system.

The missiles were to be based on the RSA-3 and RSA-4 launchers that had already been built and tested for the South African space programme. Three rockets had already been launched into suborbital trajectories in the late 1980s in support of development of the RSA-3 launched Greensat Orbital Management System (for commercial satellite applications of vehicle tracking and regional planning). Following the decision in 1989 to cancel the nuclear weapons program, the missile programs were allowed to continue until 1992, when military funding ended, and all ballistic missile work was stopped by mid-1993. In order to join the Missile Technology Control Regime the government had to allow American supervision of the destruction of key facilities applicable to both the long range missile and the space launch programmes.

Alleged collaboration with Israel

David Albright and Chris McGreal have claimed that South African projects to develop nuclear weapons during the 1970s and 1980s were undertaken with some cooperation from Israel. The United Nations Security Council Resolution 418 of 4 November 1977 introduced a mandatory arms embargo against South Africa, also requiring all states to refrain from "any co-operation with South Africa in the manufacture and development of nuclear weapons".

According to the Nuclear Threat Initiative, in 1977 Israel traded 30 grams of tritium for 50 tons of South African uranium and in the mid-1980s assisted with the development of the RSA-3 ballistic missile. Also in 1977, according to foreign press reports, it was suspected that South Africa signed a pact with Israel that included the transfer of military technology and the manufacture of at least six nuclear bombs.

In September 1979, a US Vela satellite detected a double flash over the Indian Ocean that was suspected, but never confirmed to be a nuclear test, despite extensive air sampling by WC-135 aircraft of the United States Air Force. If the Vela Incident was a nuclear test, South Africa is one of the countries, possibly in collaboration with Israel, that is suspected of carrying it out. No official confirmation of it being a nuclear test has been made by South Africa, and expert agencies have disagreed on their assessments. In 1997, South African Deputy Foreign Minister Aziz Pahad stated that South Africa had conducted a test, but later retracted his statement as being a report of rumours. In February 1994, Commodore Dieter Gerhardt, the convicted Soviet spy and former commander of South Africa's Simon's Town naval base was reported to have said:

"Although I was not directly involved in planning or carrying out the operation, I learned unofficially that the flash was produced by an Israeli-South African test code-named Operation Phoenix. The explosion was clean and was not supposed to be detected. But they were not as smart as they thought, and the weather changed – so the Americans were able to pick it up."

In 2000, Dieter Gerhardt claimed that Israel agreed in 1974 to arm eight Jericho II missiles with "special warheads" for South Africa.

In 2010, The Guardian released South African government documents that it alleged confirmed the existence of Israel's nuclear arsenal. According to The Guardian, the documents were associated with an Israeli offer to sell South Africa nuclear weapons in 1975. Israel categorically denied these allegations and said that the documents do not indicate any offer for a sale of nuclear weapons. Israeli President Shimon Peres said that The Guardian article was based on "selective interpretation... and not on concrete facts." Avner Cohen, author of Israel and the Bomb and the forthcoming The Worst-Kept Secret: Israel's Bargain with the Bomb, said "Nothing in the documents suggests there was an actual offer by Israel to sell nuclear weapons to the regime in Pretoria."

Dismantling

South African forces feared the threat of a "domino effect" in favour of Communism, represented in southern Africa by Cuban proxy forces in Angola and threatening Namibia. In 1988 South Africa signed the Tripartite Accord with Cuba and Angola, which led to the withdrawal of South African and Cuban troops from Angola and independence for Namibia.

Another possible motivation for eliminating nuclear weapons in South Africa was the probability of an ANC government in the near future.^{[citation needed]} The ANC was listed as a terrorist organisation by the USA, and it had a long history of co-operation with leaders like Muammar Gaddafi and organisations such as the PLO. The pre-emptive elimination of nuclear weapons would "make a 'significant contribution...toward peace, stability and progress,'" improving South Africa's relations with and restoring their credibility in regional and international politics. Reiss also states the opinion that the white government greatly feared the unpredictability of a black government inheriting nuclear technologies.^{[citation needed]}

South Africa dismantled its nuclear weapons program in 1989. All the bombs (six constructed and one under construction) were destroyed and South Africa acceded to the Nuclear Non-Proliferation Treaty when South African Ambassador to the United States Harry Schwarz signed the treaty in 1991. On 19 August 1994, after completing its inspection, the IAEA confirmed that one partially completed and six fully completed nuclear weapons had been dismantled. As a result, the IAEA was satisfied that South Africa's nuclear program had been converted to peaceful applications. Following this, South Africa joined the Nuclear Suppliers Group (NSG) as a full member on 5 April 1995. South Africa played a leading role in the establishment of the African Nuclear Weapons Free Zone Treaty (the Treaty of Pelindaba) in 1996, becoming one of the first members in 1997. South Africa also signed the Comprehensive Test Ban Treaty in 1996 and ratified it in 1999.

The Treaty of Pelindaba came into effect on 15 July 2009 once it had been ratified by 28 countries. This treaty requires that parties will not engage in the research, development, manufacture, stockpiling acquisition, testing, possession, control or stationing of nuclear explosive devices in the territory of parties to the Treaty and the dumping of radioactive wastes in the African zone by Treaty parties. The African Commission on Nuclear Energy, in order to verify compliance with the treaty, has been established and will be headquartered in South Africa.

Biological and chemical weapons

In October 1998, the report of the South African Truth and Reconciliation Commission included a chapter on Project Coast, a clandestine government chemical and biological warfare program conducted during the 1980s and 1990s. Project Coast started in 1983, ostensibly to produce equipment for defensive purposes, including masks and protective suits. Despite vehement assertions to the contrary, some testimony appeared to show that the programme went well beyond defensive purposes.
