RPK-6 Vodopad (Russian: РПК-6 Водопад, "waterfall") is a Soviet 533 mm anti-submarine missile deployed operationally since 1981. RPK-7 Veter (Russian: РПК-7 Ветер, "wind") is a 650 mm version, deployed operationally since 1984. Both missiles are given the same United States Navy designation SS-N-16 and NATO designation Stallion. Both missiles are torpedo-tube launched, with a solid-fuel rocket engine to power them above the surface. They are dual-role and can be armed with either a 400 mm anti-submarine torpedo or a nuclear depth charge. The Veter's increased range of approximately 100 kilometers was an impressive boost over its predecessor the RPK-2 Vyuga, which could only reach half the distance.
