Gulfstream Aerospace could be edging closer to launching the G300, a long-rumored derivative of its super-midsize G280. That's according to Hagerty Jet, a business aircraft broker that specializes in preowned Gulfstreams. The G280 is manufactured for Gulfstream in Tel Aviv by Israel Aircraft Industries (IAI).
“IAI has reported they will manufacture an upgraded version of the G280, which we speculate will be called the G300. A prototype has been designed and built but details are very secretive,” the firm said. Another industry source confirmed the level of secrecy of the codenamed P42 project, terming it “off the charts.”
Hagerty Jet said it hopes “the new model will incorporate the Gulfstream panoramic oval windows found on the larger models along with the Symmetry cockpit and a flat floor.”
It added that deliveries could begin in 2026. Industry analyst and consultant Rolland Vincent of Rolland Vincent Associates agrees with that timeline, telling AIN, “The timing would be good. Business jet models need a refresh every seven to eight years on average—and even more often if they are in a competitive segment.”
Hagerty posits that the new twinjet could be announced at NBAA-BACE later this month in Las Vegas. However, Vincent panned that idea: “It’d be hard to imagine Gulfstream announcing anything at BACE when they have said they won’t be [exhibiting] there.”
