The uninhabited combat aerial vehicle (UCAV) has its special characters of high stealth,high maneuverability, unmanned, and low life circle cost etc. Considering the features of the UCAV, and utilizing the method used in the modern aircraft cost efficiency analysis, the relationship between the main design factors, such as stealth, radius of action, maneuverability and weapon payloads, and the combat efficiency of attack UCAV was simulated. The effects of the main design factors on the life cycle cost of attack UCAV was calculated. The differences of cost efficiency among UCAVs, cruise missiles and manned aircrafts at the same threaten situation and at the same attack mission were studied. The UCAV-s position in the future war was analyzed. The study draws a conclusion that the cost efficiency of UCAVs is higher than that of manned aircrafts and cruise missiles in term of fulfilling suppression enemy air defenses mission.
