A defense contractor (or defence contractor) is a business organization or individual that provides products or services to a defense department of a government. Products typically include military aircraft, ships, vehicles, weaponry, and electronic systems. Services can include logistics, technical support and training and communications support. Defense contractors do not generally provide direct support of military operations.
