The installation was originally constructed as a steam locomotive erecting and repair facility in 1908. SCAAP was established in 1953 and operated by U.S. Hoffman until 1963 when Chamberlain Manufacturing Corporation became the operating contractor. General Dynamics, Ordnance and Tactical Systems assumed operation of the facility from Chamberlain in 2006 and is the current operating contractor. SCAAP is the recipient of the AMC Superior Unit Award (2007), and the Department of Defense Environmental Sustainability Award (2012).
