 Northrop Grumman has been trying to sell the Global Hawk internationally, and has had European interest in a EuroHawk and Middle Eastern interest in a "GulfHawk".Japan and Australia are considering the type as well, but nobody expects international sales any time soon.Sensor Craft appears to be a purely experimental program, but the confrontation between the US and China over the EP-3 SIGINT aircraft in the spring of 2001 helped increase interest in a new, large surveillance UAV.
