Gulfstream G150: Complete Specs, Performance, and Buyer's Guide (2026)
The Gulfstream G150, produced from 2006 to 2017, is the substantially refined successor to the Gulfstream G100 (formerly IAI Astra SPX) and represents the final modernization of the proven Astra family lineage that began with the 1985 IAI Astra. Over its 11-year production run, the G150 delivered meaningful improvements over the G100: wider 5 ft 9 in cabin (vs G100's 4 ft 9 in), Honeywell TFE731-40AR engines, Rockwell Collins Pro Line 21 avionics, and 2,691 nm range with seats full. The G150 is operated by two pilots with seating for up to 7 passengers. Maximum cruise reaches 459 ktas (528 mph), service ceiling is 45,000 ft. The G150 was succeeded by the Gulfstream G280 (super-midsize successor) and effectively ended production as part of Gulfstream's modernized lineup. Pre-owned market today: $6.04 million average.
For operators wanting the most-refined Astra-family variant with substantially wider cabin than the G100 predecessor, the G150 represents the platform's apex.

History as the Refined Astra Successor
The Gulfstream G150 was developed as the substantial refinement of the proven Astra platform, addressing the G100's narrow cabin (4'9") while maintaining the platform's high-performance heritage.
Platform timeline:
- 1985: Original IAI Astra
- 1990: Astra SP
- 1994: Astra SPX
- 2001: Gulfstream acquires IAI executive jet division
- 2001: Astra SPX rebranded as G100
- 2005-2006: G150 development and introduction
- 2006: G150 production begins
- 2006-2017: 11-year production run
- 2008: Gulfstream G280 introduced (super-midsize successor)
- 2017: G150 production ends
The G150 represented the final new-production midsize Gulfstream Aerospace platform before Gulfstream's mainstream offerings moved to the G280 super-midsize and ultra-long-range platforms.

Frequently Asked Questions
How is the G150 different from the G100?
The G150 (2006) introduced substantial improvements over the G100: wider cabin (5'9" vs G100's 4'9" - 12 inches wider!), slightly taller cabin (5'9" vs 5'6"), longer cabin (17'8" vs 17'1"), extended range (3,000 nm vs 2,517 nm), Pro Line 21 avionics (vs Pro Line 4), and modernized systems. The G150 is a meaningful upgrade across multiple dimensions.
How is the G150 different from the G280?
The G280 (2012-Present) is the super-midsize successor with substantially longer range (3,600 nm), larger cabin, more powerful engines, and modernized systems. The G280 is positioned as a super-midsize jet while the G150 was a midsize jet. The G280 is the larger and more capable successor in Gulfstream's lineup.
How far can a Gulfstream G150 fly?
The G150 has a maximum NBAA IFR range of 3,000 nautical miles (some sources 2,691 nm for seats full at long-range cruise).
Is the G150 single-pilot certified?
No. The G150 requires two pilots.
What is the relationship between the G150 and the Astra family?
The G150 is the final refined variant of the proven Astra family lineage that began with the 1985 IAI Astra. Heritage: Astra (1985) → Astra SP (1990) → Astra SPX (1994) → Gulfstream G100 (2001 rebrand) → Gulfstream G150 (2006 substantial refinement). The G150 represents over 30 years of platform evolution.
What engines power the G150?
Two Honeywell TFE731-40AR turbofan engines.
Why did Gulfstream end G150 production in 2017?
Gulfstream ended G150 production in 2017 as part of its lineup modernization, with the G280 (super-midsize, 2012) effectively replacing the midsize segment role and Gulfstream's focus moving to larger long-range and ultra-long-range platforms.
The Bottom Line
The Gulfstream G150 represents the apex of the proven Astra family lineage with substantial cabin widening (12 inches wider than G100), modernized Pro Line 21 avionics, and 3,000 nm range capability. With Gulfstream's worldwide service infrastructure, the G150 offers strong operational support. At current pre-owned pricing averaging $6.04 million, the G150 delivers solid value as a 6-7 passenger midsize jet with proven Israeli/Gulfstream heritage. The tradeoffs are real: 5'9" cabin height is near-stand-up but not full, and the G150 was succeeded by the larger G280 super-midsize platform. For operators valuing efficient midsize operation with Gulfstream backing, the G150 delivers.
