ASTRA/GULFSTREAM SPX

Astra / Gulfstream SPX Jets for Sale — The Evolved Super-Light

The Gulfstream 1125 Astra SPX is the definitive evolution of the Astra family — the result of IAI's continuous development of the supercritical wing jet design that began with the Westwind and reached its commercial peak with the SPX. Where the earlier 1125 SP already offered impressive speed and efficiency advantages over competing super-light jets, the SPX builds on those foundations with upgraded Honeywell TFE731-40-200G engines delivering 4,250 lbf thrust each, a new Collins Pro Line 4 digital avionics suite, enhanced passenger comfort refinements, and a range extension that makes the SPX one of the longest-legged aircraft in the super-light category. Finding an SPX for sale on Airplane Trade connects you with a jet that represents the culmination of over two decades of Israeli supercritical wing jet development.

SPX vs 1125 SP — Understanding the Differences

While sharing the same fundamental airframe and wing design as the 1125 SP, the SPX incorporates meaningful improvements that justify its premium over earlier Astra variants. The Honeywell TFE731-40 engines deliver approximately 13% more thrust than the -3A series while burning fuel more efficiently — a combination that improves both performance and economics simultaneously. The Collins Pro Line 4 EFIS cockpit replaces the earlier electromechanical instruments with full electronic flight displays that improve situational awareness and reduce pilot workload significantly. Range in IFR conditions with four passengers and NBAA reserves approaches 3,400 nautical miles, making the SPX capable of transatlantic segments with a fuel stop or transcontinental US flights nonstop with comfortable reserves.

Market Position and Value

The SPX occupies an interesting position in the pre-owned super-light market — it offers performance and range that competes favorably with aircraft that originally cost significantly more, while its Israeli heritage and somewhat lower production volumes compared to Hawker and Citation competitors mean that pre-owned prices have been historically favorable for buyers seeking value. Enrollment on Honeywell's MSP Gold engine program is available and strongly recommended. Gulfstream warranty and product support provides parts availability and technical documentation support.
