World War II consolidated this position with the company involved in many important technological advances, most notably radar.

In June 1997, British Aerospace Defence managing director John Weston commented "Europe... is supporting three times the number of contractors on less than half the budget of the U.S.".

[9] In contrast, DASA's response to the breakdown of the merger discussion was to merge with Aérospatiale to create the European Aeronautic Defence and Space Company (EADS), a horizontal integration.
