The C-20 is the military version of the civilian Gulfstream III and IV aircraft. Entering U.S. military service in 1983 as the replacement for the C-140B, the C-20 serves as a primary lift aircraft for high-ranking U.S. military and civilian officials. The C-20G (Gulfstream III) is an all-weather, long-range, high speed aircraft powered by two Rolls-Royce Spey MK511-8 turbofan engines with thrust reversers. The aircraft has an executive compartment with accommodations for five passengers and a staff compartment with accommodations for eight passengers. A walk-in baggage area of 157 cubic feet is fully pressurized and accessible from the cabin.

Later versions of the C-20 (H-model, GIV) can be configured for cargo operations, passenger operations or combinations of the two. With passengers seats removed, it may be modified to the following configurations: three pallets/no passengers, two pallets/eight passengers, and one pallet/fourteen passengers. With a full complement of seats installed, the aircraft is capable of accommodating up to twenty-six passengers and a crew of four. 

A hydraulically-operated cargo door is installed on the starboard side of the aircraft to facilitate loading and unloading of cargo. The C-20 also features a full suite of secure global communications equipment.
