Copies and derivatives of these designs were made by German, French, British and Japanese weapon manufacturers. Oerlikon Contraves was purchased by Rheinmetall, a German armament manufacturer, in 1999. , Rheinmetall Air Defence had around 1,050 employees at locations in Switzerland, Germany, Italy and Canada. The group's sales were about 380 million EUR.

History
Oerlikon's earliest predecessor was Schweizerische Werkzeugmaschinenfabrik Oerlikon, founded in Switzerland in 1906.

In 1923 it acquired a factory in Germany. It entered the anti-aircraft defence field in 1924. In 1936, it founded a purely anti-aircraft development company called Contraves (contra aves is Latin for "against birds", better translated as "anti-flying-objects") In 1989, the Werkzeugmaschinenfabrik Oerlikon-Bührle and Contraves merged to form the Oerlikon-Contraves Group, later renamed Oerlikon Contraves Defence. Oerlikon Contraves was purchased by Rheinmetall, a German armament manufacturer, in 1999, and renamed Rheinmetall Air Defence AG on 1 January 2009.

Historic products


American versions of the Oerlikon 20 mm cannon, such as the Mk 4, Mk 10, and Mk 24, were used extensively from World War II to the Vietnam War. Originally used as anti-aircraft weapons by the US Navy, they were frequently the last line of defence against kamikaze attacks. Most combat ships from aircraft carriers to PT boats were equipped with Oerlikon guns. During the Vietnam War they were widely employed by riverine forces as anti-personnel weapons. They remained in service until the 1970s, when they were replaced by the Mk 16 20 mm cannon. The surface-to-air missiles: RSA Missile, RSD 58 and Kriens RSC Missile.

Corruption charges
Rheinmetall Air Defence (RAD) is one of six companies that were blacklisted by India's Ministry of Defence in March 2012 for their involvement in a bribery scandal. The companies are accused of bribing the Director General of Ordnance Factories Board (OFB), Sudipta Ghosh. RAD and the other firms have been barred from any dealings with the OFB and all other Indian defence companies, as well as being blacklisted from participating in any Indian defence contract, for a period of 10 years. RAD has claimed that the charges against it are without merit.
