Development of the V-75 Dvina atmosphere defence missile system, designated SA-2 `Guideline' by NATO, started in 1953 as a medium to high SAM system to be used against non-manoeuvring goals such as for example bombers. The system became operational in 1957 whenever PVO-Strany formed SA-2 missile regiments of three six train launcher battalions, with one of many initial deployments near the town of Sverdiovsk. On 1 might 1960 the Sverdiovsk units fired an overall total of 14 SA-2 missiles against a Lockheed U-2 thin air reconnaissance aircraft flown by Gary Powers. The SA-2 is a two stage missile with a large solid propellant jettisonable tandem booster phase fitted with four large clipped delta stabilising fins. Towards the mid-section for the missile are four clipped delta-shaped wings with another set of little fixed fins on nose and a third in-line set of somewhat larger moving control fins at the end. The SA-2A/B/C models could be distinguished by the two sets of four, flush dielectric strip antennas in the front and behind the forward fins.
