The Kh-31 (Russian: Х-31; AS-17 'Krypton')^[7] is a Soviet and Russian air-to-surface missile carried by aircraft such as the MiG-29, Su-35 and the Su-57. It is capable of Mach 3.5 and was the first supersonic anti-ship missile that could be launched by tactical aircraft.^[6]

There are several variants; the Kh-31 is best known as an anti-radiation missile (ARM) but there are also anti-ship and target drone versions. There has been talk of adapting it to make an "AWACS killer", a long-range air-to-air missile.^[7]
