Also known by the DIA/NATO reporting name SS-N-2 STYX, the P-15 Termit is a Soviet-developed anti-shipping missile. It was the first such missile used in combat, by fast attack craft, to sink a conventional warship, the Israeli destroyer Eilat in 1967. The missile exists in a number of variants.
Obsolete against modern warships, it is still a threat to commercial shipping. While it is no longer made in Russia, other countries may produce derivatives, including Egypt, India, and North Korea. User navies have included Algeria, Angola, Bulgaria, Croatia, Cuba, Egypt, Ethiopia, Finland, India, Iraq, North Korea, Libya, Poland, Romania, Russia, Syria, Vietnam, Yemen, and Yugoslavia.
