P-15 Termit

The P-15 Termit, known to NATO as the SS-N-2 Styx, is a Soviet anti-ship cruise missile developed by MKB Raduga for small missile boats and coastal batteries. It entered service in 1960, used active radar guidance with inertial/autopilot midcourse control, and became the missile fired by coastal-defense systems such as the 4K51 Rubezh.

Open-source reporting ties it to the Al-Mandab-1 anti-ship cruise missile and the later Al-Mandab-2 family, and says the missile's launch range from the launcher does not exceed 40 km.
