Gulfstream G-1159A Gulfstream III / C-20 / SRA-1

gulfg3


The Gulfstream line and the Savannah plant were sold to American Jet Industries, which was headed by little-known aviation entrepreneur Allen Paulson.


Paulson became the president and CEO of the company, renaming it Gulfstream America. He made a priority of developing the Gulfstream III, a new aircraft designed to achieve greater range and speed than the GII. The GIII made its first flight in December 1979, with the first delivery of the aircraft occurring in 1980. It was the first business jet to fly over both poles.


The G-1159A Gulfstream III was first built in 1980.


In 1987, the 200th and last Gulfstream III produced was delivered, and the first delivery of a Gulfstream IV took place.

Based on the twin-turbofan Gulfstream III corporate jet, the C-20 Gulfstream III/TV has been purchased for US Air Force, Army, and Navy use as a VIP transport and operational support aircraft. Three aircraft were bought following an initial period of lease, and have been followed by 12 more. Three maritime patrol aircraft acquired by the Royal Danish Air Force are equipped with APS-127 search radars, INS, and a large cargo door. They can be reconfigured in less than two hours for VIP transport, troop carrying, or medevac. Another export customer, reported to be India, has bought three reconnaissance versions. Production of the Spey powered Gulfstream III ended in early 1987 with the transition to the Gulfstream IV, which uses Tay engines.

A Gulfstream III completed as the SRA-l de-monstrator first flew on 14 August 1984 from Travis Field, Savannah, Georgia. It had been extensive-ly tested with a number of the sensor systems proposed for some of the SRA-4 roles, including an under fuselage Side-Looking Airborne Modular Multimission Radar.

In 1987, the 200th and last Gulfstream III produced was delivered, and the first delivery of a Gulfstream IV took place.
