In 1945 the Air Force Cambridge Research Laboratories were established. These laboratories were active from 1945 to 2011, following consolidation to Wright-Patterson Air Force Base and Kirtland Air Force Base under the 2005 Base Realignment and Closure Commission. The labs were founded as the Air Force Cambridge Research Center (AFCRC), a Cold War systems development organization which developed telephone modem communications for a Digital Radar Relay in 1949. Created by General Henry H. Arnold in 1945, AFCRC participated in Project Space Track and Semi-Automatic Ground Environment development.
