Boeing Defense, Space & Security (BDS) is a division (business unit) of The Boeing Company based in Arlington, Virginia. It is responsible for defense and aerospace products and services. It was formerly known as Boeing Integrated Defense Systems (IDS). Boeing Integrated Defense Systems was formed in 2002 by combining the former "Military Aircraft and Missile Systems" and "Space and Communications" divisions. Boeing Defense, Space & Security made Boeing the third-largest defense contractor in the world in 2021. Boeing Defense, Space & Security is a consolidated group that brought together major names in aerospace; Boeing Military Airplane Company; Hughes Satellite Systems; Hughes Helicopters minus the civilian helicopter line (which was divested as MD Helicopters); Piasecki Helicopter, subsequently known as Boeing Vertol and then Boeing Helicopters; the St. Louis-based McDonnell division of the former McDonnell Douglas Company; and the former North American Aviation division of Rockwell International. History Boeing Defense, Space & Security was headquartered in Greater St. Louis north of St. Louis Lambert International Airport in the northern St. Louis suburb of Berkeley, Missouri until January 2017, when top executives and support staff were relocated to Arlington, Virginia. There are also significant operations in nearby Missouri communities, such as Hazelwood and St. Charles. It remains one of the largest employers in Greater St. Louis with 13,707 local employees as of 2018. Other major locations of BDS are in California and Washington state. Boeing chose to locate the defense systems offices in the St. Louis area because of the role of the space and aircraft programs of the former McDonnell Douglas location, and bipartisan support from area politicians. Organization Boeing BDS was reorganized in June 2018: In November 2022, Boeing consolidated its defense, space and security business from eight divisions into four, according to a company statement. Those reorganized divisions now focus on vertical lift; mobility, surveillance and bombers; air dominance; and space, intelligence and weapons systems, led by Ted Colbert, president and chief executive officer of BDS.
