 Indeed, since the Navy found themselves increasingly committed to the use of expensive cruise missiles to perform punitive strikes and other limited military operations, UCAVs offered a potentially cheaper alternative, a "reusable cruise missile".One UCAV could carry a number of smart GPS-guided munitions and hit multiple targets on a single sortie, and then return home to be used again.Even with a high combat attrition rate, the cost would be less than that of a barrage of cruise missiles.
