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.
