Air Defense Missile Weapon System

The air defense missile weapon systems is composed of medium range interceptor (LY-80 series against aerial vehicle and anti- ship missile) and short range air defender (FB series and FN series) with an envelope of 10-20,000m altitude and 0.5-70km slant range, which constitutes a national or area defense system for area air defense, point air defense, fortification air defense and marching air defense. Featuring quick response, strong anti-jamming capability, highly automated fire control, good compatibility for joint combat mission, high maneuverability, easy operation, simple maintenance and battle proven performance, the air defense missile systems are the best choice for modern air defense needs.



LY-70 Mobile Air Defense Missile Weapon System is designed to intercept air targets such as high-performance combat aircrafts, cruise missiles, air-to-ground missiles, UAVs, guided ammunitions & rockets and attack helicopters in high-density attack and strong electro-magnetic interference conditions in all weather at day and night. The system is mainly used for critical asset air defense and escort air defense.

The LY-70 combat vehicle integrates AESA search & tracking radar, E/O search & tracking device, weapon control, missile launch, two types missiles including active radar homing guidance missiles (LY-70R missile) and IR staring imaging missiles (LY-70IR missile) .


  • High Integration Level & Quick Reaction
