预警机作为二战后发展起来的一个特殊机种,迄今为止,其发展已经历了三代。美国、前苏联、英国等发达国家先后共研制了20多种预警机。目前,全世界在役的各种预警机大约共有224架,其中美国拥有各型预警机115架,数量为世界之最。历次局部战争一再证明,预警机不仅已成为现代战场上信息传输的重要节点,而且在争夺战场制信息权的斗争中,其作用变得越来越突出。因此,世界各国尤其是以美国为首的军事强国,纷纷加大了对预警机开发的经费投入力度,积极改装现役预警机或研制新型预警机,以期在未来战场上抢占制信息的主动权。
Early warning aircraft as a special aircraft developed after World War II, so far, its development has gone through three generations. The United States, the former Soviet Union, Britain and other developed countries have successively developed more than 20 kinds of early warning aircraft. At present, there are about 224 all kinds of AWACSs in service throughout the world, of which the United States has 115 early warning aircraft of any type, the largest number in the world. Previous local wars have repeatedly proved that AWACS has not only become an important node for information transmission in the modern battlefield, but also has become increasingly prominent in the battle for the battlefield information rights. Therefore, all countries in the world, especially the military powers headed by the United States, have stepped up their efforts in funding the development of early warning aircraft and actively modified the active early warning aircraft or developed new early warning aircraft in the hope of seizing control over information in the future battlefield.
