2002年5月22日,波音公司研制的X-45A验证机成功地完成了首飞(题图)。作为第一架专门设计用于执行空战任务的无人驾驶战斗机(UCAV),X-45A验证机在14分钟飞行中,飞行速度超过360千米/小时,飞行高度达到2280米。虽然这次短暂的首飞只是UCAV发展过程中的一小步,但预示着未来空战模式的变革从此拉开序幕。研制计划悄然启动早在越南战争期间,面对大量作战飞机被地面防空火力击落的现实,美国空军就萌发了研制无人战斗机的想法,但是此后一直受到一些关键技术的限制。进入二十世纪九十年代,随着气动、控制、通信和弹药等尖
May 22, 2002, Boeing developed the X-45A Verifier successfully completed the first flight (Figure). As the first UCAV specifically designed to perform air combat missions, the X-45A validates over a 14-minute flight speed of over 360 km / h and a flying height of 2,280 meters. Although this brief first flight is just a small step in the development of UCAV, it indicates that the future changes in the air combat mode will start. Development plan quietly started As early as the Vietnam War, in the face of the reality that a large number of combat aircraft were shot down by surface air defense firepower, the United States Air Force had the idea of developing an unmanned combat aircraft but has since been restricted by some key technologies. Into the nineties of the twentieth century, along with pneumatic, control, communications and ammunition tip
