 C-20**The C-20 was retired Aug. 30, 2017.**

**Mission**

The C-20 is a twin-engine, turbofan aircraft acquired to fill the airlift mission for high-ranking government and Department of Defense officials. The 89th Airlift Wing, Joint Base Andrews, Md., operates five C-20Bs for worldwide special air missions. The 86th Airlift Wing, Ramstein Air Base, Germany, operates two C-20Hs for operational support airlift missions.

**Features**
Two Rolls Royce Spey Mark 511-8 engines power the C-20B models. The primary difference between the C-20B and H models is the electrical system, engines, and the avionics package. Two Rolls Royce Tay Mark 611-8 engines power the C-20H. These engines provide greater performance, greater range and have a reduced noise signature compared to the B model. The C-20H is also slightly longer than the B model, and has an upgraded avionics package and interior. Worldwide secure and non-secure passenger communication capability exists on both aircraft.**Background**
The C-20A/B, military versions of the Gulfstream III, was chosen in June 1983 as the replacement aircraft for the C-140B Jetstar. Three A models were delivered to the 89th Airlift Wing under a cost-saving accelerated purchase plan. Upon delivery of the C-20Bs, Andrews transferred the three C-20As to Ramstein Air Base and all C-140Bs at both locations were phased out of the U.S. Air Force inventory. In 1992, Gulfstream delivered their latest model, the C-20H (Gulfstream IV) to Andrews AFB. In 2002, the C-20A was selected for decommissioning and two C-20Hs at Andrews were transferred to Ramstein.**General Characteristics
