History

Entered service in 1988 as the world's first supersonic air-launched cruise missile, Kh-31 uses an integrated ramjet that pushes it to Mach 3.5 in the terminal phase.

Kh-31A is the active-radar anti-ship variant; Kh-31P is the passive anti-radiation SEAD version. The family spawned the Chinese YJ-91 and inspired the MA-31 supersonic target drone for the US Navy.
