Unless they're using a different airframe no. the Preadator has no vertical stabaliser and the tailplane angles downward not up. Plus (unless that's somehting in the background) it doesn't have any projections like the one on the nose. Gear looks to thin but over all a dangerous (if kinda cute) looking UCAV
modified its a modified version. different sizes and as noticed different control surfaces. it is designed as a weapons platform instead of being a recon craft. perhaps the first operational attack UAV.
Not to MY knowledge. They did some remote-sensor work on the Ho Chi Minh trail, but these were supposedly 'read' by highly-modified Lockheed EC-121 "Connies" IIRC. Tim
