The McDonnell Douglas C-9 is a military version of the McDonnell Douglas DC-9. It was produced as the C-9A Nightingale for the United States Air Force, and the C-9B Skytrain II for the U.S. Naval Reserve and United States Marine Corps. The final active-duty US Air Force flight was in September 2005 [1], and the Boeing C-40 Clipper is replacing the US Navy Reserve's aging C-9B fleet[2][3].


The C-9 fleet was located throughout the continental United States, Europe, and Asia. The Navy and Marine Corps C-9B aircraft provided cargo and passenger transportation as well as forward deployed air logistics support. The Air Force C-9A Nightingales were used for medical evacuation (MedEvac), passenger transportation, and special missions. A C-9B was chosen by NASA to replace the aging KC-135 Stratotanker Vomit Comet.

Many of the Navy's C-9B types have a higher (114,000 lb or 52,000 kg) maximum gross take-off weight and are fitted with auxiliary fuel tanks installed in the lower cargo hold to augment the aircraft's range to nearly 2,600 nautical miles (4,200 km) for overseas missions along with tail mounted infra-red (IR) scramblers to counter heat seeking missile threats in hostile environments.


  • C-9A Nightingale - 20 aeromedical evacuation aircraft for the United States Air Force.
  • C-9B Skytrain II - 21 transport aircraft for the United States Navy and Marine Corps.
  • VC-9C - 3 executive transport aircraft for the United States Air Force. Three aircraft (73-1681, 73-1682, 73-1683) were delivered to the US Air Force in late 1976.
  • C-9K - 2 aircraft for the Kuwait Air Force.
