近年来,无人机在几场局部战争中的突出表现引起了世界各国的极大关注。一些军事强国纷纷加大投入,研发各种性能更优、功能更多、能力更强的先进无人机,在战场侦察、校射甚至火力攻击方面,大有追赶和超过有人驾驶飞机的趋势。有人预测,在不远的将来,无人机等智能化武器的大量出现将导致“无人化”战场的出现,而无人机届时也会成为新的空中霸主。——编者 In recent years, the outstanding performance of UAVs in several local wars has drawn great attention of all countries in the world. Some military powers have stepped up their investments in research and development of advanced UAVs with better performance, more functions and stronger capabilities. They have been able to catch up and surpass manned aircraft in battlefield reconnaissance, school shooting and even fire attacks. Some people predict that in the near future, the emergence of a large number of intelligent weapons such as UAVs will lead to the emergence of “unmanned” battlefields, and the drones will also become the new air superiority by then. --editor
