The Ch-25 (another designation: AS-10 Karen) was a Soviet short-range air-to-ground missile. Its first prototypes appeared in the early 1970s, and it was used by the armed forces of the USSR in 1975. The missile is still used by the armed forces of the Russian Federation to this day. The AS-10 Karen was a missile with a range - depending on the version - from 11 to 60 kilometers, capable of carrying a warhead weighing up to 140 kg, with a total curb weight of up to 315 kg.
The Zwiezda Ch-25 missile was developed on the basis of many components of the Ch-23 rocket, but it differed from it in two major respects. First, it carried a much larger warhead, and second, it was aimed at the target by illuminating it with a laser beam, which meant installing a completely different guidance system. Many variants of the Zwiedza Ch-25 missile appeared in the course of serial production. These include, for example: Ch-25ML (model with a tandem warhead), Ch-25MS (model using GLONASS guidance) or Ch-27 (model designed to destroy enemy radar stations). The missile can be carried by such planes as, for example: MiG-21, MiG-23, MiG-27, Su-27, Su-30 or Ka-52 helicopters. The Ch-25 tour missiles have also been operated by foreign customers, including Algeria, India, Ukraine and Vietnam.
