USAF C-20 airplane model. The C-20 is a military modification of the commercial Gulfstream aircraft, manufactured by Gulfstream Aerospace Corporation (GAC) Savannah, Georgia. The C-20 aircraft provide distinguished visitor (DV) airlift for military and government officials. They support the long range/low passenger load DV airlift niche, offering worldwide access while including a communications suite which supports worldwide secure voice and data communications for the DV and staff. It also transports the U.S. President into airports where the larger VC-25 (747) cannot operate.
The C-20 is one of the mainstays of AMC's special air mission [SAM] fleet. Their mission, often dealing with highly visible and sensitive diplomatic issues, requires the utmost physical and communications security as SAM passengers conduct highly sensitive business enroute. Mission protocol dictates the use of civilian airports almost exclusively. The 89th Airlift Wing, Andrews Air Force Base, MD, operates five B-model and two H-model C-20s for worldwide special air missions. The 86th Airlift Wing, Ramstein Air Base, Germany, operates three A-models for operational support airlift.
