Function: The C-20 Gulfstream III is a twin-engine, turbofan aircraft acquired to fill the airlift mission for high-ranking government and Defense Department officials. From the 89th Airlift Wing, Andrews Air Force Base, Md, seven B-model C-20s fly special air missions.







History: The C-20 was chosen in June 1983 as the replacement aircraft for the C-140B Jetstar, and three A models were delivered to the 89th Air Wing under a cost-saving accelerated purchase plan. The three C-20As at Andrews Air Force Base were transferred to Ramstein Air Base, Germany, and all C-140Bs at both locations were phased out of the U.S. Air Force inventory.







Description: The C-20 is powered by two Rolls Royce Spey MK511-8 engines. The primary difference between the C-20A and B model is the electrical system and the avionics package.
