Title: Gulfstream III (C-20)

The Gulfstream executive jets have always been the “Rolls-Royce” of executive jets, starting with the Gulfstream II of 1966, using very powerful turbofan engines and with an extremely long range. The Gulfstream III model was introduced in 1979 and included a lengthened fuselage and a new supercritical wing incorporating winglets. Several Gulfstream III’s have been supplied to air forces and to various US military forces. Those supplied to the USAF are designated C-20B and those supplied to the US Navy are designated C-20D’s.
