Gulfstream G-159 Gulfstream I / C-4

 

gulfg1


Dubbed the Gulfstream I (GI), the turbo-prop aircraft was named after the Gulf Stream, the current that flows along the coast of Florida, which was a favored vacationing spot for Grumman executives. The Gulfstream I is a business transport designed to carry a crew of two with 10 to 14 passengers, which was introduced in 1958. Power is provided by twin Rolls-Royce Dart turboprop engines turning four-blade Rotol constant-speed propellers.


The Gulfstream I first flew on 14 August 1958 and was the first United States twin-engine business aircraft to be certificated to cruise at 30,000 feet, and had a maximum speed of 350 mph at 25,000 feet and a range of 2,200 miles.


A later version received certification as a 24-passenger variation for feeder-line use. Two Gulfstream offspring were enlisted for military use: the VC-4A was a U.S. Coast Guard transport and the TC-4C was an “avionics classroom” for the U.S. Navy.


The aircraft, specifically for business travel, was a success in the business world, prompting Grumman to develop a jet-powered corporate aircraft called the Gulfstream II or GII.
