Gulfstream III

The Gulfstream III is a twin-engine business jet built by Gulfstream Aerospace at Savannah, Georgia, as an improved development of the Grumman Gulfstream II. Its designers kept the Gulfstream II wing box and trailing edge surfaces but gave it a new wing with about six feet more span, five-foot winglets, a longer leading edge, a fuselage two feet longer aft of the main door, a longer radome and a new curved windshield. Two Rolls-Royce Spey turbofans power it, and the FAA type certificate was issued on 22 September 1980. A total of 202 were built, the last in 1986, and the United States armed forces flew military versions as the C-20A to C-20E. The Gulfstream III was also the first business jet designed to fly over both poles.
