The Gulfstream IV family, including the IV, IV-SP, G400, and G450, is the most widely operated large-cabin heavy-jet platform in the Dallas corporate market: up to 16 seats, 4,220 nautical miles of range, and a Rolls-Royce Tay 611-powered airframe that covers the US domestic network and most Latin American routes nonstop from DFW.
Gulfstream introduced the GIV in 1985 as a clean-sheet design replacing the G3 airframe, with two Rolls-Royce Tay 611-8 turbofans and a new wing. The IV-SP (special performance) arrived in 1992 with increased range and performance improvements. Gulfstream later designated the updated versions G400 and G450 under its new naming convention. Seats 14 to 16 in a typical configuration. Range runs from approximately 4,220 nautical miles on the G450 to slightly less on earlier IV variants. The PlaneView cockpit on the G450 is a modern avionics standard; earlier IV cockpits vary. Full specifications for the Gulfstream IV are published by Gulfstream Aerospace.

Why the Gulfstream IV Fits Dallas
The Gulfstream IV series carries more range than most DFW heavy-jet routes require domestically, which translates into wider fuel margins and more scheduling flexibility. Dallas to New York at roughly 1,500 nautical miles, Dallas to Los Angeles at about 1,200 nautical miles, and Dallas to Toronto at approximately 1,500 nautical miles are all deep inside the envelope. A G450 departing KDFW, the international airport with its 13,401-foot primary runway, handles a full-cabin departure with maximum fuel and no performance constraint.
Dallas to London at roughly 5,000 nautical miles sits just beyond the G450’s 4,220-nautical-mile range. With favorable tailwinds and a moderate cabin load, some operators have completed transatlantic legs with a single stop; others plan a tech stop in Newfoundland or Reykjavik. For DFW-based companies sending board delegations to Europe, this is the conversation to have before the trip, not during. The G550 and larger Gulfstream variants address the nonstop transatlantic case cleanly.
For the Latin American routes that matter to DFW’s energy sector, the G450 covers Dallas to Bogota (roughly 1,900 nautical miles) and Dallas to Caracas (roughly 1,700 nautical miles) nonstop with a full group of 14 to 16. That capacity and range combination is why the G4 family remains a frequent answer for multi-executive energy-sector trips from the Metroplex.
