预警机是雷达和飞行器相结合的产物,其载机或者说飞行平台,有固定翼飞机,也有直升机等,基本上都是由现有型号改装而成的。迄今为止,世界上绝大多数预警机都是由固定翼飞机改装而成的,是空中预警机的主体,其技术和功能也是最先进的。而由直升机或其它飞行器改装的预警机型号很少,作用也有限,暂时还处于辅助地位。但是,由于预警直升机具有机动灵活的特点,很适合在舰上使用,这也可能是它的发展方向。目前,有代表性的预警直升机型号主要有两种,一种是英国研制的,另一种是俄罗斯研制的。 AWACS is a combination of radar and aircraft products, its carrier or flight platform, a fixed-wing aircraft, but also helicopters, etc., are basically converted from existing models. So far, most of the AWACS aircraft in the world have been converted from fixed-wing aircraft. They are the mainstay of the AWACS and their technology and functions are also the most advanced. However, the types of early warning aircraft modified by helicopters or other aircraft are limited and their role is limited. They are still in a supplementary position for the time being. However, due to the flexibility of early warning helicopters, it is suitable for use on ships, which may also be its development direction. At present, there are mainly two types of representative early warning helicopters, one developed in Britain and the other developed in Russia.
