It is an air-breather. By the shape of the exhaust plume, it is a stealth UAV, IMHO.

Agreed. A new UAV in test flight.

Now...had it stopped stone cold in the air and made a radical 90 degree turn on a dime at that speed, with the F-18 flying out of the picture and turning wildly to try and get back on its wing...then I may have started thinking differently.
