The Aeronautical Systems Center (ASC) is an inactivated Air Force product center that designed, developed and delivered weapon systems and capabilities for U.S. Air Force, other U.S. military, allied and coalition-partner warfighters. ASC managed 420 Air Force, joint and international aircraft acquisition programs and related projects; executed an annual budget of $19 billion and employed a workforce of more than 11,000 people located at Wright-Patterson Air Force base and 38 other locations worldwide. ASC's portfolio included capabilities in fighter/attack, long-range strike, reconnaissance, mobility, agile combat support, special operations forces, training, unmanned aircraft systems, human systems integration and installation support. ASC was deactivated during a July 20, 2012 ceremony held at Wright-Patterson Air Force Base, Ohio. History Early Aviation The Airplane Engineering Department, precursor of ASC, was first established under the U.S. Army's Aviation Section, U.S. Signal Corps in late 1917 at McCook Field. Early on the department's focus was flight testing and training. The department was renamed the Airplane Engineering Division following World War I, it continued its mission of flight testing and training, but also began development and engineering. One early native model, the VCP-1 was designed by resident engineers, Alfred V. Verville and Virginius E. Clark. Another aircraft tested was the MB-1, eventually used as the standard mail plane. The division also expanded operations to Wilbur Wright Field. The division also pioneered aviation safety with the use of free-fall parachutes and the development of protective clothing, closed cockpits, heated and pressurized cabins, and oxygen systems. As the stockpile of aircraft and parts grew the division was able to spend more time finding ways to enhance tools and procedures for pilots. Advancements include things like an electric ignition system, anti-knock fuels, navigational aids, improved weather forecasting techniques, stronger propellers, advancements in aerial photography, and the design of landing and wing lights for night flying. In 1925 the division's roll shifted from design and building of to acquiring and evaluating aircraft prototypes submitted by the commercial aircraft industry. This left division engineers were left free to concentrate on developing standards unique to military aircraft, reviewing designs, modifying and testing procured machines, and developing ancillary equipment to enhance military aircraft. The Engineering Division merged with the Supply Division in 1926 to form the Material Division. The new unit required more space than McCook Field offered, so in an effort to keep the Air Service presence at Dayton, Ohio a local interest
