P-15 FLAT FACE

The S-125 NEVA-M (SA-3 GOA) long-range surveillance and target acquisition is handled by the van-mounted P-15 FLAT FACE radar. The P-15 radar has been replaced in many S-125 units by the P-15M SQUAT EYE radar, which has the antenna mounted on a 20-30 m mast for improved low altitude coverage. The accompanying PRV-11 SIDE NET E-band height-finding radar has a range of 180 km covering targets at altitudes of up to 32000 meters.
