GULFSTREAM III
Gulfstream III: The American Widebody Pioneer
The 1979 Large Cabin Revolution
In 1979, Grumman (later Gulfstream) introduced the Gulfstream III — the first American large cabin business jet with transatlantic range. The GIII was a GII with winglets, more powerful engines, and increased fuel capacity — evolutionary, not revolutionary, but transformative.
Specifications That Established Dominance
• Range: 6,667 km (3,600 nm) — New York to London, Los Angeles to Tokyo
• Speed: 850 km/h (459 knots) — Mach 0.85 maximum
• Capacity: 12 – 19 passengers in the signature Gulfstream cabin
• Engines: Two Rolls-Royce Spey RB.168 (11,400 lbf) — powerful, thirsty
• Winglets: Reduced drag by 7%, increased range by 5%
The GIII became the backbone of corporate fleets, government operations, and VIP transport worldwide. It established Gulfstream as the large cabin leader.

The Market Today
Pre-owned Gulfstream III aircraft trade between $400,000 and $800,000 — project aircraft for enthusiasts. Most have been retired due to Stage 3 noise restrictions and high operating costs. Operating costs: $4,000 – 5,500 per hour — the price of 1970s technology.
The Verdict
The Gulfstream III is aviation's classic muscle car — powerful, thirsty, and legendary. It established Gulfstream's large cabin dominance.
For the buyer seeking a GIII, you're acquiring history — the aircraft that made Gulfstream the name in large cabin aviation.
