OVERVIEW:  The SA-5b GAMMON (5V28) aka S-200V Vega is a static, two stage, liquid fuel, long-range, medium-to-high altitude, SARH guided surface-to-air missile.  It has a 217 kg HE fragmentation warhead. 

DETAILS: The SA-5b GAMMON series was designed for the defense of important administrative, industrial and military installations from air attack.  Before launch, an aft looking antenna on the missile is receives the target illumination from the 5N62 SQUARE PAIR radar. This reference signal is then used for detection of the backscatter off the target.  This missile is launched using four solid-fueled strap-on rocket boosters. Approximately five seconds after launch, these burn out and separate, and the liquid fueled sustainer ignites to continue the remainder of the boost phase. The missile uses radio illumination mid-course correction to fly towards the target with a terminal semi-active radar homing phase.
