The Gulfstream III was built at Savannah, Georgia, in the United States and was designed as an improved variant of the
Compared to the
In 2013, the FAA modified 14 CFR part 91 rules to prohibit the operation of jets weighing 75,000 pounds or less that are not stage 3 noise compliant after December 31, 2015. The Gulfstream III is listed explicitly in Federal Register 78 FR 39576. Any Gulfstream IIIs that have not been modified by installing Stage 3 noise compliant engines or have not had "hushkits" installed for non-compliant engines will not be permitted to fly in the contiguous 48 states after December 31, 2015. 14 CFR §91.883 Special flight authorizations for jet airplanes weighing 75,000 pounds or less – lists special flight authorizations that may be granted for operation after December 31, 2015.
By 2018, prices for a used 1982 Gulfstream III started at $695,000.[5]
Variants
Civil variants

Special mission variants
A NASA Gulfstream C-20A (83-0502 cn 389) has been fitted with a centerline pylon to allow it to carry the Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR) pod.[10]
A NASA Gulfstream III (N992NA cn 309) has also been fitted with a centerline pylon to allow it to carry the Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) pod, a modification of the UAVSAR pod.[11]
The
N30LX (cn 438) has been modified by the addition of a ventral canoe and sensor turret as the "Dragon Star" Airborne Multi-Intelligence Laboratory for use by Lockheed Martin.[15] This has been leased by Italy since 2012.[16]
Calspan operates N710CF (cn 448), which has been modified as an airborne test bed. Modifications include a centerline pylon[17] and a dorsal satcom radome[18]
Two Gulfstream IIIs, K2961 (cn 494) and K2962 (cn 495), equipped with long-range oblique photography cameras mounted in the fuselage, were delivered to the Indian Air Force.[19][20]
