Gulfstream is developing clean sheet successors to its G450 and G550 large-cabin business jets, incorporating concepts and systems designed for its flagship G650, reports Flightglobal affiliate FlightBlogger.
Citing industry sources familiar with the new aircraft, FlightBlogger reports that that the smaller model, set to replace the G450, is currently in the engine selection phase for the first of the two aircraft.
Gulfstream declined comment, saying the company "does not comment on new programs or rumors of new programmes until it is ready to announce a programme publicly."
