The NPO Almaz S-200 Angara/Vega/Dubna (Russian Ангара\Вега\Дубна), NATO reporting name SA-5 Gammon, is a very long range, medium-to-high altitude surface-to-air missile (SAM) system designed to defend large areas from bomber attack or other strategic aircraft. Each battalion has 6 single-rail missile launchers for the 10.72 m (35 ft) long missiles and a fire control radar. It can be linked to other, longer-range radar systems.

The first S-200 operational regiments were deployed in 1966 with 18 sites and 342 launchers in service by the end of the year. By 1966, the S-200 was officially accepted into service in order to replace the failed anti-ballistic missile RZ-25/5V11 "Dal". The Dal was assigned the NATO reporting name SA-5 "Griffon" before it was cancelled. By 1968 there were 40 sites, and by 1969 there were 60 sites. The growth in numbers then gradually increased throughout the 1970s and early 1980s until the peak of 130 sites and 1,950 launchers was reached in 1985.[1]

Each missile is launched by 4 solid-fueled strap-on rocket boosters. After they burn out and drop away (between 3 to 5.1 seconds from launch) it fires a 5D67 liquid fueled sustainer rocket engine (for 51–150 seconds) which burns a fuel called TG-02 Samin (50% xylidine and 50% triethylamine), oxidized by an oxidizing agent called AK-27P Melange (fuming nitric acid enriched with nitrogen oxides, phosphoric acid and hydrofluoric acid).[3] Maximum range is between 150 and 300 km (81 and 162 nmi), depending on the model.[4] The missile uses radio illumination mid-course correction to fly towards the target with a terminal semi active radar homing phase. Maximum target speed is around Mach 4. Effective altitude is 300 to 20,000 m (1,000 to 65,600 ft) for early models and up to 35,000 m (115,000 ft) for later models. The warhead is either 217 kg (478 lb) high explosive fragmentation (16,000 2g fragmentation pellets and 21,000 3.5g pellets) triggered by radar proximity fuse or command signal, or a 25 kt nuclear warhead triggered by command signal only. Each missile weighs around 7018 kg (15,500 lb) at takeoff.[4]
The system utilises radio semi active guidance with mid-course correction and has, for the first time in a Russian system, terminal semi active radar homing, which is far more accurate at long range than the command guidance method used by the S-75 Dvina and other missiles. The existence of an optional terminal passive radar homing mode for use against AEW aircraft remains unconfirmed. Peak missile speed is around Mach 8 and the single-shot kill probability is quoted as 0.85, presumably against a high altitude bomber-type target.
The fire control radar of the S-200 system is the 5N62 (NATO: Square Pair) CW H band radar, whose range is 270 km (168 mi). It is used for both the tracking of targets and their illumination.
On 4 October 2001 during a military exercise, a Ukrainian S-200 battery may or may not have missed its intended target and accidentally shot down a Tu-154 airliner en route from Tel Aviv, Israel to Novosibirsk, Siberia, killing all 78 people on board(see Siberia Airlines Flight 1812 accident).
