CHANTILLY, Va. (April 16, 2012) – The SI Organization, Inc. (the SI) has named retired Air Force Lt. Gen. John T. “Tom” Sheridan as vice president of its National Security Space line of business.

General Sheridan retired in August 2011 as the Commander, Space and Missile Systems Center, Air Force Space Command, Los Angeles Air Force Base, Calif.

General Sheridan served as the Deputy Director of the National Reconnaissance Office; as Program Executive Officer and Director for Space Radar; Commandant of Air Command and Staff College; and Director of Requirements for Air Force Space Command. His experience includes acquisition leadership of space, aircraft and simulator programs; requirements development across all Air Force space programs; and operational leadership in four different national space programs.
