PSD Anacostia

**PSD Anacostia** (Presidential Support Detachment, Anacostia) was a specialized United States Navy unit based at Naval Support Facility Anacostia, Washington, D.C. Established during the Cold War era, its primary mission was to provide transportation, security, and logistical support for senior government and military officials, including the President and Vice President. The unit operated a fleet of helicopters and maintained a high state of readiness for rapid response to executive transport needs within the National Capital Region. Over time, its responsibilities and assets were integrated into larger commands such as the Naval Support Activity Washington and Marine Helicopter Squadron One (HMX-1), reflecting evolving support requirements for executive missions.
