Grob Bases HALE Aircraft on New SPn Jet
Grob is developing a new high-altitude long-endurance aircraft based on the new SPn Utility Jet. Dubbed the G600 HALE, the aircraft could be used on surveillance or research tasks operating at extremely high altitudes. With a 116.80-foot wingspan, the basic G600 will have a range of 5,540 nm and an endurance of some 17 hours. However, an ER variant of the G600 would extend the endurance to 18 hours 30 minutes.
