Learjet 35

C-21A

The C-21A is an "off the shelf" military variant of the Learjet 35A, with room for eight passengers and 42 ft³ (1.26 m³) of cargo.

In addition to its normal role, the aircraft is capable of transporting litters during medical evacuations.

Delivery of the C-21A fleet began in April 1984 and was completed in October 1985. Dyncorp International provides full contractor logistics support at seven worldwide locations.


There are 38 Air Force active duty aircraft, and 18 Air National Guard aircraft in the C-21A fleet.

On 1 April 1997, all continental U.S.-based C-21As were realigned under Air Mobility Command, with the 375th Airlift Wing at Scott Air Force Base, Illinois, as the lead command. C-21As stationed outside the continental United States are assigned to the theater commanders.
