As a consequence, the manufacture of such vehicles is an important driver of growth. The U.S., France, China, the UK, Germany, and Russia are ranked among the leading markets for global aerospace equipment. The key contractors of military aircraft include the Airbus Group (originally known as the European Aeronautic Defence and Space Company, or EADS, until 2013), Boeing, and Lockheed Martin.
As well as these prominent firms, there are several multinational consortia which are involved in the manufacture of aircraft, such as the Eurofighter, which was a jet designed and manufactured by a consortium of three companies: Airbus, BAE Systems, and Alenia Aermacchi. Furthermore, one of the largest military contracts worldwide, signed in October 2001, involved the development of the Joint Strike Fighter (JSF), a project intended to replace a wide range of existing aircraft, which saw the collaboration of several countries including the United States, the United Kingdom, Italy and Canada.
