In most industrial countries, the aerospace industry is a cooperation of public and private industries. For example, several countries have a civilian space program funded by the government through tax collection, such as NASA in the United States, ESA in Europe, the Canadian Space Agency in Canada, Indian Space Research Organization and Hindustan Aeronautics Limited in India, RKA in Russia, China National Space Administration in China, SUPARCO in Pakistan, Iranian Space Agency in Iran, and Korea Aerospace Research Institute (KARI) in South Korea.
Along with these public space programs, many companies produce technical tools and components such as spaceships and satellites. Some known companies involved in space programs include Boeing, EADS, Lockheed Martin, MacDonald Dettwiler and Northrop Grumman. These companies are also involved in other areas of aerospace such as the construction of aircraft.
Aerospace manufacturing is a high technology industry that produces "aircraft, guided missiles, space vehicles, aircraft engines, propulsion units, and related parts". Most of the industry is geared toward governmental work. For each Original Equipment Manufacturer (OEM), the US government has assigned a CAGE code. These codes help to identify each manufacturer, repair facilities, and other critical aftermarket vendors in the aerospace industry.
