The aircraft engineering industry
The global aircraft industry encompasses a vast network of companies working either as large international conglomerates or as individual national and regional organizations. The two biggest international aircraft manufacturers are the American owned Boeing Aircraft Company and the European conglomerate, European Aeronautic Defence and Space Company (EADS), which incorporates airbus industries. These, together with the American giant Lockheed-Martin, BAE Systems and aerospace propulsion companies, such as Rolls-Royce and Pratt and Whitney, employ many thousands of people and have annual turnovers totalling billions of pounds. For example, the recently won Lockheed-Martin contract for the American Joint Strike Fighter (JSF) is estimated to be worth 200 billion dollars, over the next 10 years! A substantial part of this contract will involveBAESystems,Rolls-RoyceandotherUK companies.
