The Grumman Gulfstream II was originally designed as a business jet, but an enlarged version would eventually serve in feeder airline use. This aircraft evolved from the Gulfstream I turboprop, which was introduced in 1958. 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.
