Tom Sheridan

The SI Organization has appointed retired Air Force Lt. Gen. Tom Sheridan as vice president of the national security space business unit, the company announced Monday.

The national security space unit supports space programs for intelligence agencies, the Defense Department and NASA.

President and CEO Bill Graham said the company has known Sheridan since the early 1990s and supported national defense space projects that he led.

The 34-year Air Force veteran retired in August 2011 as commander of the branch’s Space and Missile Systems Center in Los Angeles.

His military career includes service as deputy director for the National Reconnaissance Office and as program executive officer for space.

As PEO for space, he oversaw the research, design, development, acquisition, and sustainment of satellite, launch and command and control systems.

He has also served as commandant of the Air Command and Staff College, PEO for space radar and as a military assistant to both the NRO director and the Air Force’s assistant secretary for space.

The company acquired McLean, Va.-based defense and intelligence communications provider PhaseOne Communications in February.
