Department of Defense Manned Space Flight Support Office

The Department of Defense Manned Space Flight Support Office (DDMS) coordinated all United States Department of Defense (DoD) contingency support to NASA's human spaceflight programs. The office was deactivated in 2007 and replaced by a staff element that is part of the United States Space Force's 45th Space Wing staff at Patrick Space Force Base in Florida.
