The Kh-80 Meteorit-A (GRAU-code: 3M25A, NATO: AS-X-19 Koala), the RK-75 Meteorit-N (GRAU: 3M25N, NATO: SS-NX-24 Scorpion) and the P-750 Meteorit-M (Russian: П-750 Гром, GRAU: 3М25, NATO: SSC-X-5) was a Soviet cruise missile which was supposed to replace subsonic intermediate range missiles in Soviet inventory.

Development of three variants of this cruise missile was authorized on 9 December 1976.

The first launch from a 667M Andromeda submarine took place on 26 December 1983 from the Barents Sea.

It was equipped with a 1 Mt thermonuclear warhead and used inertial navigation with mid-course update via data link.
