The 2K12 "Kub" (Russian: 2К12 Куб; English: ' cube ') (NATO reporting name: SA-6 "Gainful") mobile surface-to-air missile system is a Soviet low to medium-level air defence system designed to protect ground forces from air attack. 2К12 is the GRAU designation of the system.

Surface-to-air missile 3M9 Like the Krug complex, the missile 3M9 is designed as a "rotary wing". However, unlike the ZM8 missile, the ZUR 3M9 rocket was additionally equipped with stabilizer rudders.

It had an integrated acquisition radar and assisted four 2P25 Transporter Erector Launcher (TEL) which carried each three 3M9 missiles (NATO nicknamed them the "three fingers of death"). In supportwere deployed four or more 2T7 transloader/transporters trailers …

The 3M9 missile design introduced the first solid propellant ramjet engine in a Soviet missile, resulting in a missile with superior range performance to its conventional solid rocket competitors, as the missile did not need to carry the mass of the full oxidiser component of the propellant.

The 3M9 (3М9) is a Soviet-era-developed, rocket-boosted, ramjet powered, low to medium-level, command and semi-active radar guidance, surface to air missile (SAM). The 3M9 forms the SAM component of the 2K12 (2К12) Kub (Куб) SAM system.

Air Defense Missile System - Inspired by the 2K12 series. The export version of 2K12 became 2K12E "Kvadrat", and since then these have been widely used in Soviet/Russian allies and countries. The 3M9M1 became a variant in 1977 with an all-new tracked undercarriage, which NATO referred to as "SA-6B".
