Russia’s aerial campaign in Syria is being used to test weapon systems that have not previously been employed under combat conditions – including the Raduga Kh-101 air-launched cruise missile.

The new Russian Kh-101 air-launched cruise missile crash in Iran on the outskirts of the city of Shush on Nov. 20.

A Kh-101 air-launched cruise missile fired by Russia towards Syria failed and landed inside Iran.

The Kh-101 is an advanced cruise missile under development to eventually replace the Kh-55 missile onboard the Soviet/Russian strategic bombers such as Tu-160 and Tu-95. The Kh-101 has a 400-kg conventional warhead, stealth features, high subsonic speed and low altitude flight profile. The conventionally-armed Kh-101 has also been referred to as the Russian counterpart to the United States Air Force AGM-129 air launched cruise missile.
