Heres a very interesting pic that I found,its probably the first appearance [2014] of the drone that would go on,in modified form,to become the airforces Kaman 12 ucav.
Later on the nose would be enlarged and the landing gear modified.
Before finally being modified again with a larger nose,a larger engine and prop,and some extensions to the tail and wingtips.Possibly the tail booms have been modified and strengthened as well.
Its crazy how much bigger the nose has gotten,and I certainly dont think that these modifications have improved its looks any.
