The V-750 is a two-stage missile consisting of a solid-fuel booster and a storable liquid-fuel upper stage, which burns red fuming nitric acid as the oxidizer and kerosene as the fuel.
The booster fires for about 4–5 seconds and the main engine for about 22 seconds, by which time the missile is traveling at about Mach 3.
The booster mounts four large, cropped-delta wing fins that have small control surfaces in their trailing edges to control roll.
The upper stage has smaller cropped-deltas near the middle of the airframe, with a smaller set of control surfaces at the extreme rear and (in most models) much smaller fins on the nose.

The missiles are guided using radio control signals (sent on one of three channels) from the guidance computers at the site.
The earlier S-75 models received their commands via two sets of four small antennas in front of the forward fins while the D model and later models 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 it 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, freeing the radio channel.

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 (213 ft) at lower altitudes, but 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 (246 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 kiloton yield or a conventional warhead of similar weight.

Typical range for the missile is about 45 km (28 mi), with a maximum altitude around 20,000 m (66,000 ft).
The radar and guidance system imposed a fairly long short-range cutoff of about 500 to 1,000 m (1,600 to 3,300 ft), making them fairly safe for engagements at low level.
