无人机已经越来越多地投入到了实际战斗。在阿富汗战争中,美军广泛使用了“捕食者”无人机。由于在伊拉克遭到抵抗力量的持续袭(xi)击,美军迫不及待地将大量各种型号的无人机投入战场,前后使用的无人机达700架之多,大有取代有人驾驶飞机的趋势。显然,与侦察、监视、对地攻击型无人机相比,无人战斗机的功能更复杂,性能更先进,造价也更昂贵,但它的广泛使用只是迟早的事情。无人战斗机的出现将彻底改变21世纪的作战模式,甚至有可能 UAVs are increasingly being put into actual combat. In the war in Afghanistan, the U.S. military made extensive use of the Predator UAV. Due to sustained attacks by Iraqi resistance forces, the U.S. military could not wait to put a large number of UAVs on the battlefield. As many as 700 unmanned aerial vehicles were used to replace the manned aircraft . Obviously, unmanned combat aircraft are more complex, more advanced and more expensive than reconnaissance, surveillance and ground attack UAVs, but their widespread use is only a matter of time. The emergence of unmanned combat aircraft will completely change the 21st-century mode of operation, and may even be possible
