The Soviet S-75 Dvina was developed in the early 1950s as a medium to high altitude surface-to-air missile for use against bombers and other non-manoeuvering targets. It is designated SA-2 "Guideline" by NATO. It is a two stage missile with a large solid propellant jettisonable tandem booster stage with four large clipped delta stabilising fins. The mid stage has four clipped delta shaped wings with a second set of small fixed fins at the nose and a third set of control fins at the tail.
