The Tor (Russian: Top; English: torus[2]) is an all-weather, low-to medium-altitude, short-range surface-to-air missile system designed for destroying airplanes, helicopters, cruise missiles, unmanned aerial vehicles and short-range ballistic threats (anti-munitions). Originally developed by the Soviet Union under the GRAU designation 9K330 Tor, 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 designed to shoot down guided weapons like the AGM-86 ALCM and BGM-34[3] day and night, in bad weather and jamming situations.[4] Tor can detect targets while on the move. The vehicle must stop intermittently when firing,[5][6] although trials have been conducted with the aim of eliminating this restriction.
