Development of the V-75 Dvina environment defence missile system, designated SA-2 `Guideline' by NATO, started in 1953 as a medium to high SAM system to be utilized against non-manoeuvring goals such as for instance bombers. The system became functional in 1957 whenever PVO-Strany formed SA-2 missile regiments of three six train launcher battalions, with among the many initial deployments nearby the town of Sverdiovsk. On 1 might 1960 the Sverdiovsk devices fired a complete of 14 SA-2 missiles against a Lockheed U-2 nothing reconnaissance aircraft flown by Gary Powers. The SA-2 is a two stage missile with a big solid propellant jettisonable tandem booster phase fitted with four large clipped delta stabilising fins. Towards the mid-section the missile are four clipped delta-shaped wings with another pair of little fixed fins on nose and a third in-line set of notably larger moving control fins by the end. The SA-2A/B/C models might be distinguished by the 2 sets of four, flush dielectric strip antennas into the front and behind the forward fins.
