C-9 Skytrain


United States Marine Corps -- Provides cargo and passenger transportation to the fleet and forward deployment logistics support.


The C-9B Skytrain is a military version of the McDonnell Douglas DC-9-32 airliner. Modified with upper cargo doors, the C-9 provides unique logistics capabilities, particularly airlift personnel to and from training sites and the movement of naval personnel to support ship deployments. The C-9 can haul cargo, passengers or a combination of the two. Beginning in 2001, the C-40A aircraft began replacing the C-9 fleet.
