The Kh-31P ARM was introduced into service in the Soviet Union in 1988, while the Kh-31A anti-shipping variant was introduced the following year, in 1989

The NATO reporting designation for the missile is AS-17 Krypton

The Kh-31 Krypton is an advanced anti-ship missile ( ASM ) that is designed to penetrate modern ship defences and inflict significant damage to enemy vessels

The missile is designed to fly at low altitudes, typically just a few meters above the water’s surface. This makes it difficult to detect and track with radar

The missile can be equipped with different types of warheads, depending on the mission requirements.
