Gulfstream Aerospace will cease production of the midsize G150 next year so it can “focus on the super-midsize and large-cabin jet markets,” Mark Burns, president of the Savannah, Georgia-based aircraft manufacturer, announced today. The company’s line-up will thus consist of the G280 in the super-midsize category and the G450, G500, G550, G600 and G650/650ER in the large-jet segment.

The G150—a derivative of the G100/Astra SPX—is manufactured under contract by Israel Aerospace Industries in Tel Aviv. Today’s announcement will mark the end of the G150’s more than 10-year production run, though shipments of the original IAI Astra began in the mid-1980s. According to Gulfstream, the last G150 has recently been ordered and will be delivered in mid-2017.

“The G150 has had a distinguished history, spanning more than a decade,” said Burns, “and it remains an important part of our business. Our product support organization will continue to provide support to our G150 owners and ensure there are enough parts, tooling, sustaining engineering and personnel available [for] the worldwide G150 fleet.”

Nearly 120 G150s are currently in service around the world and the twinjet is certified in more than 45 countries, including the U.S., Brazil, Canada, China, England, Germany, Israel and Switzerland.
