Aircraft 2006, SA-2 Guideline, nose and guidance
The missiles are guided using radio control signals from the guidance computers at the site, sent on one of three channels. The earlier S-75 models received their commands via two sets of four small antennas in front of the forward fins, while the D models and on used four much larger strip antennas running between the forward and middle fins. The guidance system at an S-75 site can handle only one target at a time, but can direct three missiles against it. Additional missiles could be fired against the same target after one or more missiles of the first salvo had completed their run and the radio channel was freed.
The missile typically mounts a 195 kg (430 lb) fragmentation warhead, with proximity, contact and command fusing. The warhead has a lethal radius of about 65 m (215 ft) at lower altitudes, while at higher altitudes the thinner atmosphere allows for a wider radius of up to 250 m (820 ft). The missile itself is accurate to about 75 m (250 ft), which explains why two were typically fired in a salvo. One version, the SA-2E, mounted a 295 kg (650 lb) nuclear warhead of an estimated 15 kt yield, or a conventional warhead of similar weight.
