Gulfstream G-1159 Gulfstream II

glfstg2


The Gulfstream I, the first of its kind designed 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.


The Grumman Gulfstream II was originally designed as a business jet, but an enlarged version would eventually serve in feeder airline use. Production of the swept-wing Model II version with turbofan engines started in 1965, and the first delivery was in 1967. It is one of the larger business jets, with a gross weight of 58,000 pounds. It is also one of the fastest, with a top speed of 589 mph, and it has a long-range capability of up to 3,600 miles.

The 200th Gulfstream II was delivered in 1977.


In 1981, Gulfstream introduced the Gulfstream GIIB. The GIIB had a modified GII fuselage and the GIII wings, complete with winglets. The variant offered weight and performance characteristics similar to the GIII, but with the shorter GII fuselage. Gulfstream completed and delivered approximately 40 GIIBs.


The 256th and final GII delivery took place in 1977.
