HQ-7 / FM-80/-90 Feimeng 80
The Feimeng 80 air defense missile is a point defense missile that is usually deployed to ammunition depots or military bases. Its mission is similar to that of the "Avenger" missile. With an effective engagement range of 12-15km the system uses an E/F-band Acquisition radar and a J-band Engagement radar.
In order to reduce the danger of being hit by the enemy's air defense units, fighter bombers now use ultra-low-altitude flight to launch surprise assaults against ground targets. Ordinary radar and air defense missiles are relatively ineffective against planes and helicopters using this kind of tactics, flying at altitudes of scores of meters. Under such circumstances, low-altitude air defense missiles specially designed to hit objects flying in low altitudes have become increasingly important.
In the early 1990s China first publicly displayed its first mobile low-altitude and ultra-low-altitude missile -- the "Feimeng (Flying Midge)-80." Using a combination of infrared, television and radar guidance systems, this air defense missile system is under wireless command control all the way, which gives it excellent resistance to passive jamming, active jamming and crustal and meteorological noises. Compared to similar types of advanced air defense missiles abroad, the "Feimeng-80" is superior to the US Chaparrel, the British Rapier, and the German and French Roland in all-weather capability, combat response time, combat air space, and ability to deal with multiple targets. Its overall performance is comparable to the improved Sidewinder.
At the end of 1998, the "Feimeng-90," an improved version of the "Feimeng-80," was introduced. Compared to the old system, the target seeking range of the new system is increased from 18,400 meters to 25,000 meters, the homing range is increased from 17,000 meters to 20,000 meters, the maximum speed is increased from 750 meters/second to 900 meters/second, and the maximum range is increased from 12,000 meters to 15,000 meters, thus enhancing its long-range combat capability. At the same time, its maximum ultra radio frequency height is reduced from 30 meters to 15 meters. The new system also makes use of two-waveband radar instead of ordinary radar and features an improved television tracking system, which greatly increases its combat effectiveness.
