According to Wikipedia: "The Tor missile system (Russian: "Тор"; English: torus) is an all-weather low to medium altitude, short-range surface-to-air missile system designed for engaging airplanes, helicopters, cruise missiles, precision guided munitions, unmanned aerial vehicles and short-range ballistic threats (Anti-Munitions). Originally developed by the Soviet Union under the GRAU designation 9K330, the system is commonly known by its NATO reporting name, SA-15 "Gauntlet". A navalized variant was developed under the name 3K95 "Kinzhal", also known as the SA-N-9 "Gauntlet". Tor was also the first air defence system in the world designed from the start to shoot down precision guided weapons like the AGM-86 ALCM."
