The Gulfstream III and Gulfstream IV commercial corporate jets have served as the framework for the "C-20" family of U.S. military government-level VIP passenger transports. The Gulfstream III covers the C-20A, C-20B, C-20C and C-20D models while the Gulfstream IV is the C-20F (U.S. Army), C-20G (USMC), C-20H (USAF) and C-20J (U.S. Army). The Gulfstream III was introduced by Gulfstream Aerospace in 1980 and 202 were built while the Gulfstream IV achieved better commercial success, entering service in the mid-1980s and has seen production reach 870 units. Both variations are twin-engine jets of conventional form and function.

The original C-20A and C-20B production models were selected to succeed the outgoing line C-140B JetStar aircraft then in service with the USAF. The C-20A held provision for 14 passengers and carried a crew of five. The C-20B (2 x Rolls-Royce Spey 511-8 engines) arrived in 1992 with updated avionics and electronics while the C-20C introduced protected communications for its passengers. The C-20D was taken on by the United States Navy (USN) as an Operational Support Airlift (OSA) type and given appropriate mission equipment for the role of transporting high-ranking USN officials. The C-20E arrived as a "stretched fuselage" model and given slightly reworked wing mainplanes, serving the United States Army.

The SRA-1 became a specialized variant intended for reconnaissance and surveillance for the export market. Similarly, the SMA-3 became a radar-equipped version for maritime patrol, Search & Rescue and VIP transport for Denmark.

For the USAF, three C-20A examples were delivered to the 89th Airlift Wing and these were then shipped to Ramstein AFB in Germany. The C-20B arrived powered by 2 x Rolls-Royce Spey Mark 511-8 series engines.

The C-20H was another stretched fuselage version (powered by 2 x Rolls-Royce Tay 611-8 engines) and this arrived in 1992 as a more advanced model with modernized avionics, uprated engines and new electrical system offering improved range, performance and noise reduction.

The C-20A was given up in frontline service by the USAF in 2002. To fill the gap at Ramstein, a pair of C-20H models were shipped to Germany in their place.
