RPK-6 Vodopad (, "waterfall") is a Soviet 533 mm anti-submarine missile deployed operationally since 1981.
RPK-7 Veter (, "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. Theys 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.
