How big is an unmanned drone airplane?

These UAV have to climb down to lower altitude when firing their hellfire missile which apparently has a very short range of 8 km… enough range for MANPADS to shoot them down.

gunships?? lol.. PA desperately need those upgraded cobras and latest AH-64 for their anti-terror operations… shooting them down with american gunships will jeopardize these possible deals..
Mirage-III Rose upgraded are most suitable for this job… plus.. insallah by the end of this year.. 1st combat capable squadron of JF-17 will be delivered with BVR missiles.. maybe they may get the shot.. lol..
