Gulfstream G300 (Heritage): Complete Specs, Performance, and Buyer's Guide (2026)
The Gulfstream G300 (Heritage variant, in production from 2003 to 2004) is the shorter-range sibling of the Gulfstream G400 in the rebranded G-IV/GIV-SP lineage. Announced by Gulfstream in December 2002 immediately after ceasing production of the GIV, the G300 was designed to meet growing demand for a stand-up cabin with generous aisle space and comfortable seating without the need for long-range capability. Per BusinessAirNews: "The G300 production run was initiated just after the 500th GIV model was produced and ceased in 2004, when it was superseded by the G350, a shorter-range version of the G450." Powered by two Rolls-Royce Tay Mk 611-8 turbofan engines (each producing 13,850 lbf of thrust, same engines as G-IV/GIV-SP, 8,000-hour TBO), the G300 delivers Mach 0.88 max speed (498 knot high-speed cruise / 446 knot long-range cruise), 3,485-3,600 nm range (per FlyCraft / 3,399 NM seats-full per AircraftCostCalculator), 45,000 ft service ceiling, 3,805 ft/min climb rate. Cabin: 45.08 ft length, 7.25 ft width, 6.17 ft height, 1,525 cu ft volume. 169 cu ft internal baggage capacity. 13-16 passengers (typical 14, max 16). Honeywell SPZ-8400 integrated avionics suite with six-tube electronic flight instrument system. Dual Collins 442 DME, triple Collins VHR-442B comms, dual Collins VIR-432 navs, Honeywell Primus 880 weather radar, Honeywell HUD. 4,015 gallon fuel capacity. 540 GPH average fuel burn. 4,700 ft takeoff distance, 4,417 ft landing distance. 27,700 lb total thrust. Aircraft: light alloy airframe with carbon composites ailerons/spoilers/rudder/elevators, aluminium honeycomb winglets. Pre-owned average per AircraftCostCalculator: $7.66M. New list at manufacture per FlyCraft: $26M. Hourly charter estimate $6,500. Production ceased 2004 when superseded by G350.
For operators wanting Gulfstream's accessible large-cabin variant with the same Tay engines as G-IV/GIV-SP/G400, transcontinental 3,485-3,600 nm range capability, 45,000 ft service ceiling, 1,525 cu ft cabin volume with stand-up Gulfstream comfort, Honeywell SPZ-8400 six-tube EFIS, accessible $7.66M pre-owned market, and premium Gulfstream heritage, the G300 represents Gulfstream's most accessible large-cabin heavy-iron platform.

History as the Accessible Heritage Large-Cabin Variant
The G300 represents Gulfstream's strategic decision to offer an accessible large-cabin variant with shorter-range capability for operators who didn't need full transcontinental range.
Platform timeline:
- 1987: G-IV enters service
- 1993: GIV-SP introduced
- December 2002: G300 + G400 announced (immediately after 500th GIV produced)
- December 3, 2002: 500th and final GIV/GIV-SP (N499GA, c/n 1499) rolled out
- 2003: G300 production begins
- 2004: G300 production ends (superseded by G350)
- 2005: G350 introduced (shorter-range G450 variant with PlaneView cockpit)
Per BusinessAirNews: "Gulfstream announced the G300 in December 2002, immediately after ceasing production of the GIV. The new aircraft was designed to meet growing demand for a stand-up cabin with generous aisle space and comfortable seating, without the need for long-range capability."

Frequently Asked Questions
How is the G300 different from the G400?
The G300 (2003-2004) and G400 (2003-2008) are sibling Heritage variants announced together December 2002. Same Tay Mk 611-8 engines, same Honeywell SPZ-8400 avionics, same airframe. Key differences: G300 has 3,485-3,600 nm range (vs G400's 4,100+ nm), G300 designed for operators not requiring long-range capability, G300 substantially shorter production run (2003-2004 vs G400's 2003-2008).
How is the G300 different from the G350?
The G350 (2005-2014) is the direct successor to the G300. Key improvements: PlaneView avionics system (vs G300's SPZ-8400), shorter-range version of G450 (vs G300 as shorter-range version of G400), Tay Mk 611-8C engines (vs G300's Tay Mk 611-8 - C-variant adds FADEC), 3,900 nm range (vs G300's 3,485-3,600 nm). Per BusinessAirNews: "The G350 is powered by the same two Tay MK 611-8C engines as the G450, but with room for less fuel its range is reduced to 3,900 nm."
What engines power the G300?
Two Rolls-Royce Tay Mk 611-8 turbofan engines, each producing 13,850 lbf of thrust (61.6 kN flat rated to ISA +15°C). Total thrust: 27,700 lbf. 8,000-hour TBO. Same engines as G-IV, GIV-SP, G400.
How far can a G300 fly?
The G300 has a range of 3,485-3,600 nm per FlyCraft (3,399 nm seats-full per AircraftCostCalculator). At long-range cruise (446 knots), the G300 can fly 14 passengers from Chicago to London (~3,950 nm). At Mach 0.8 cruise with 4 passengers + 2 crew and NBAA IFR reserves per Gulfstream: theoretical range.
When was the G300 produced?
The G300 was announced by Gulfstream in December 2002 immediately after ceasing GIV production (500th and final GIV/GIV-SP rolled out December 3, 2002 as N499GA). Production began 2003 and ended 2004 - very short production run. It was superseded by the G350 in 2005 (the PlaneView-equipped shorter-range version of the G450).
What's the G300 pre-owned market like?
Pre-owned G300 average price per AircraftCostCalculator: $7.66M. New list at manufacture per FlyCraft: $26M. The very short production run (2003-2004) limits market depth, but the G300 represents accessible large-cabin Gulfstream heritage at substantially lower acquisition cost than G400/G450 variants.
The Bottom Line
The Gulfstream G300 (Heritage variant, in production from 2003 to 2004) represents Gulfstream Aerospace's accessible large-cabin Heritage variant offering the same proven Tay 611-8 engines and stand-up Gulfstream cabin as the larger G400 at a lower acquisition cost for operators not requiring long-range capability. With substantial accessible capabilities (two Rolls-Royce Tay Mk 611-8 turbofan engines providing 13,850 lbf each at 61.6 kN flat rated to ISA +15°C with 8,000-hour TBO and 27,700 lbf total thrust - the same engines as G-IV/GIV-SP/G400, Mach 0.88 max speed with 498 knot high-speed cruise and 446 knot long-range cruise, 3,485-3,600 nm range per FlyCraft enabling Chicago to London long-range cruise capability, 45,000 ft service ceiling, 3,805 ft/min climb rate, substantial cabin of 45.08 ft length + 7.25 ft width + 6.17 ft stand-up height + 1,525 cu ft volume + 169 cu ft internal baggage in three distinct cabin zones, Honeywell SPZ-8400 integrated avionics suite with six-tube electronic flight instrument system + dual Collins 442 DME + triple Collins VHR-442B comms + dual Collins VIR-432 navs + Honeywell Primus 880 weather radar + Honeywell head-up display HUD, 4,700 ft takeoff distance + 4,417 ft landing distance + 4,015 gallon fuel capacity + 540 GPH fuel burn, aft galley with solid marble surface + Sharp microwave + B/E Aerospace high-temperature oven + dual TIA coffeemakers + espresso maker + stainless steel sink), the G300 delivered Gulfstream's accessible large-cabin Heritage variant. Per BusinessAirNews: "Gulfstream announced the G300 in December 2002, immediately after ceasing production of the GIV. The new aircraft was designed to meet growing demand for a stand-up cabin with generous aisle space and comfortable seating, without the need for long-range capability." The G300 production run was initiated just after the 500th GIV model was produced and ceased in 2004 when it was superseded by the G350 (a shorter-range version of the G450 with PlaneView avionics). Standard configuration accommodates 13-14 passengers typical (up to 16 maximum) in three distinct cabin zones. New list at manufacture per FlyCraft: $26M. Pre-owned average per AircraftCostCalculator: $7.66M. Hourly charter rate $6,500. Annual operating cost $4.57M based on 450 hours per AircraftCostCalculator. Total operating cost per hour $10,169. Premium Gulfstream heritage. Strong residual value within accessible large-cabin market. Gulfstream worldwide service network continues to support the G300 platform.
