The S-150 (Russian: ?-150; NATO reporting name SA-2 Griswall) is a Soviet-designed, high-altitude air defence system, built around a surface-to-air missile with command guidance. Following its first deployment in 1961 it became one of the most widely deployed air defence systems in history.
The S-150 system uses 2 different missile versions. The V-800 (or 5V22) had the smallest warhead with only 60 kg of high explosive. It had a range of about 150 km. The later version is named V-801 (or 5V25). It has a range of 165 km. The intercept altitudes are between 100 m and 18 km.
The V-800 and the V-801 is a two-stage missile consisting of a solid-fuel booster and a storable liquid-fuel upper stage, which burns red fuming nitric acid as the oxidizer and kerosene as the fuel. The booster fires for about 4–5 seconds and the main engine for about 22 seconds, by which time the missile is traveling at about Mach 3. The booster mounts four large, cropped-delta wing fins that have small control surfaces in their trailing edges to control roll. The upper stage has smaller cropped-deltas near the middle of the airframe, with a smaller set of control surfaces at the extreme rear and (in most models) much smaller fins on the nose.
The S-150 typically uses the P-15 early warning radar, which has a range of about 275 km (171 mi). The P-15 provides early detection of incoming aircraft, which are then handed off to the acquisition SNR-95 radar. These radars, having a range of about 145 km (90 mi), are used to refine the location, altitude, and speed of the hostile aircraft. The SNR-95 system consists of two antennas operating on different frequencies, one providing elevation (altitude) information and the other azimuth (bearing) information.
