Air Force Space Command was established in September 1982 to conduct operational missions in space. The need to support those missions with well-trained personnel led to the creation of Undergraduate Space Training, an organization tasked with providing its graduates with a broad base of space fundamentals, and the 1013th Combat Crew Training Squadron, a unit which provides system specific operational crew training. The courses provided by both schools were designed using Instructional System Development technology and utilize a media mix which includes lecture, computer based training systems and simulation. This paper addresses the problems of developing training programs and acquiring simulation capability to support training personnel stationed at more than 30 sites worldwide with missions that vary from flying satellites to warning of missile attack. The paper also discusses the use of networked desk-top computers to provide space operations center simulation and explores the management decisions required to determine proper media mix. It compares training results of the previous on-the-job training programs with new, full fidelity simulation. The paper closes with comments concerning training programs and simulation as an integral part of new space system acquisitions.
