(The system was reportedly designed to defend advancing Soviet tank divisions in case of the war)
System Developer V.V.Tikhomirov Science and Research Institute of Instrument-Engineering (NIIP)
Chief Designer of the System: Yevgeniy Pigin
Missile Developer State Machine-building Design Bureau Vympel (Moscow)
Serial Production Facility Ul'yanovsk Mechanical Plant (for launchers and reconnaissance facility)
CHRONOLOGY
Development started late 1950s
Testing started 1965 (Army)
Serial Production started 1968 [1] or 1967 [3]
Production ceased1983 [3] or 1985 [1]
PERFORMANCES:
System Composition One Self-Propelled Reconnaissance and Targeting Facility and 4 Self-propelled SAM Launchers, each carrying three missiles (all on tracked chassis). Initial version of the system carried 3M9 missiles, Kub-M3 features 3M9M3 missiles
Probability of kill by one missile (within the lethality envelope) To increase Pk target can be engaged by several missiles, fired from either single or several Launchers
for non manuevering aerodynamic target 0.8-0.9 [1], 0.7-0.8 [2] 0.8-0.95 [3]
for manuevering high-speed target 0.5-0.7 [2]
for cruise missile 0.3-0.4 [1] 0.1-0.3 [2]
Missile Guidance semi-active radar homing
(on recently upgraded complexes TV/optical seeker introduced)
For protection aganst anti-radar missiles seeker of SAM can lock on target mid-air, after launch

Performance Upgrade Activity In the interests of foreign customers NIIP currently upgrades the system to increase efficiency of tracking targets at low altitudes and improve jam-resistance of illumination channel. Work is also underway to increase combat performance can be enhanced by inclusion of a newer 9A310M1 Self-propelling Launcher from Buk-M1 SA-17) system
ExportsWas delivered to 22 [1] or 25 [3] countries, including Syria and Yugoslavia. Extensively used in the 1973 Israeli-Arab war (64 airplanes were shot down by 95 fired missiles)
