The 89th Airlift Wing, Andrews Air Force Base, Md., operates five C-20B's for worldwide special air missions. The 86th Airlift Wing, Ramstein Air Base, Germany, operates two C-20H's 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 model is the electrical system, engines, and the avionics package. Two Rolls Royce Tay Mark 611-8 engines power the C-20H. The Tay Mark 611-8 engines provide greater performance, greater range and are reduced noise signature than 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-20B's, Andrews transferred the three C-20A's to Ramstein Air Base and all C-140B's 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.

Since February 2003, VR-51 has deployed C-20G Gulfstream aircraft to the Persian Gulf region in support of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). The primary mission of the squadron is to transport the staff of U. S. Central Command (CENTCOM) around the region. VR-51 completed 183 missions, flying 1826 hours while transporting 2595 passengers and 117,250 pounds of cargo during that time spent in the Persian Gulf region.
