The Kh-25/Kh-25M (Russian: Х-25; NATO: AS-10 'Karen') is a family of Soviet lightweight air-to-ground missiles with a modular range of guidance systems and a range of 10 km. The anti-radiation variant (Kh-25MP) is known to NATO as the AS-12 'Kegler' and has a range up to 40 km. Designed by Zvezda-Strela, the Kh-25 is derived from the laser-guided version of the Kh-23 Grom (AS-7 'Kerry'). The Kh-25 remains in widespread use despite the apparent development of a successor, the Kh-38.

Based on an air-to-air missile, the beam-riding Kh-66 had been the Soviet Union's first air-to-ground missile for tactical aircraft, entering service in 1968. However it proved difficult to use in practice as the launch aircraft had to dive towards the target. A version with radio-command guidance, the Kh-23, was first tested in 1968 but problems with the guidance system meant that it would not enter service for another five years. So in 1971 work began on a version with a semi-active laser seeker, which became the Kh-25. This was initially known in the West as the Kh-23L. State testing began on 24 November 1974, and the Kh-25 entered production in 1975.
