The V-75 (SA-2) surface-to-air missile system was designed for the defense of both fixed targets and field forces. The V-75 was designed to cope with the threat posed by small groups of aircraft rather than massed raids. Flexibility and mobility are its chief advantages over the SA-1. In contrast to the massive SA-1 sites, each of which is capable of defending only a limited sector around the target area, each SA-2 site is capable of 360 coverage. This flexibility is obtained at the expense of target handling capacity and rate of fire relative to the SA-1. It is intended for defeat of manned and pilotless air attack weapons at the heights from 100 m to 30 km, which fly with speeds of up to 3000 km/h, at the distances to 58 km.
