S-300 Air Defense System
The S-300 (NATO reporting name SA-10 Grumble) is a series of initially Soviet and later Russian long range surface-to-air missile systems produced by NPO Almaz, based on the initial S-300P version.
The S-300 system was developed to defend against aircraft and cruise missiles for the Soviet Air Defence Forces. Subsequent variations were developed to intercept ballistic missiles.
The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defence of large industrial and administrative facilities, military bases and control of airspace against enemy strike aircraft.
The system is fully automated, though manual observation and operation are also possible. Components may be near the central command post, or as distant as 40 km. Each radar provides target designation for the central command post.
The command post compares the data received from the targeting radars up to 80 km apart, filtering false targets, a difficult task at such great distances. The central command post features both active and passive target detection modes.
The project-managing developer of the S-300 is Almaz-Antey. S-300 uses missiles developed by both MKB "Fakel" and NPO Novator design bureaus (separate government corporations, previously named "OKB-2" and "OKB-8").

The S-300 is regarded as one of the most potent anti-aircraft missile systems currently fielded. It is mainly used in Asia and Eastern Europe, including three NATO member countries: Bulgaria, Greece and Slovakia. An evolved version of the S-300 system is the S-400 (NATO reporting name SA-21 Growler), which entered limited service in 2004.
Serial production of S-300 started in 1975. The tests have been completed in 1978 (P) and 1983 (V + 1987 for anti-ballistic V). Numerous versions have since emerged with different missiles, improved radars, better resistance to countermeasures, longer range and better capability against short-range ballistic missiles or targets flying at very low altitude. There are currently three main variations.
An important quality of all complexes of the family of S-300 is the ability to work in various combinations within a single modification and within the same complex, between the modifications (limited), as well as through a variety of mobile superior command posts to line up in a battery of any composition, quantity, modifications, location and so on including the introduction of other air defence systems into a common battery. Capable of hitting ballistic and aerodynamic targets. Became the first multi-channel anti-aircraft missile system, is able to accompany each system (ADMS) to 6 goals and build them up to 12 missiles. When creating funds management (FM), consisting of paragraph combat control and radar detection, solved the problem of automatic track initiation of up to one hundred goals and effective management divisions, located at a distance of 30–40 km from the (FM).

For the first time established a system with full automation of combat operation. All tasks—detection, tracking, target setting is considered, target designation, development of target designation, target acquisition, maintenance, capture, tracking and missile guidance, assessment of results of firing system capable of dealing automatically with the help of digital computing facilities.
The operator functions are to control over the work of funds and implementation of the launch of rockets. In a complex environment, you can manually intervene in the course of combat operation. None of the previous systems possessed these qualities. Vertical launch missiles provided bombardment of targets flying from any direction without the reversal of the launcher in the direction of the shooting.

Missiles are guided by the 30N6 FLAP LID or naval 3R41 Volna (TOP DOME) radar using command guidance with terminal semi-active radar homing. Later versions use the 30N6 FLAP LID B or TOMB STONE radar to guide the missiles via command guidance/seeker-aided ground guidance (SAGG). SAGG is similar to the Patriot's TVM guidance scheme.
The earlier 30N6 FLAP LID A can guide up to four missiles at a time to up to four targets, and can track up to 24 targets at once. The 30N6E FLAP LID B can guide up to two missiles per target to up to six targets simultaneously. Targets flying at up to Mach 2.5 can be successfully engaged or around Mach 8.5 for later models. One missile can be launched every three seconds. The mobile control centre is able to manage up to 12 TELs simultaneously.

The original warhead weighed 100 kg (220 lb), intermediate warheads weighed 133 kg (293 lb) and the latest warhead weighs 143 kg (315 lb). All are equipped with a proximity fuse and contact fuse. The missiles themselves weigh between 1,450 and 1,800 kg (3,200 and 3,970 lb). Missiles are catapulted clear of the launching tubes before their rocket motor fires, and can accelerate at up to 100 g (1 km/s²).
They launch straight upwards and then tip over towards their target, removing the need to aim the missiles before launch. The missiles are steered with a combination of control fins and through thrust vectoring vanes. The sections below give exact specifications of the radar and missiles in the different S-300 versions. Since the S-300PM most vehicles are interchangeable across variations.
The 30N6 FLAP LID A is mounted on a small trailer. The 64N6 BIG BIRD is mounted on a large trailer along with a generator and typically towed with the now familiar 8-wheeled truck. The 76N6 CLAM SHELL (5N66M etc.) is mounted on a large trailer with a mast which is between 24 and 39 m (79 and 128 ft) tall. Usually is used with a mast. Target detection range of 90 km if altitude of the target of 500 meters above the ground (with a mast).
The original S-300P utilises a combination of the 5N66M continuous-wave radar Doppler radar for target acquisition and the 30N6 FLAP LID A I/J-band phased array digitally steered tracking and engagement radar. Both are mounted on trailers. In addition there is a trailer-mounted command centre and up to twelve trailer-mounted erector/launchers with four missiles each. The S-300PS/PM is similar but uses an upgraded 30N6 tracking and engagement radar with the command post integrated and has truck-mounted TELs.

If employed in an anti-ballistic missile or anti-cruise missile role, the 64N6 BIG BIRD E/F-band radar would also be included with the battery. It is capable of detecting ballistic missile class targets up to 1,000 km (620 mi) away travelling at up to 10,000 km/h (6,200 mph) and cruise missile class targets up to 300 km (190 mi) away. It also employs electronic beam steering and performs a scan once every twelve seconds.
The 36D6 TIN SHIELD radar can also be used to augment the S-300 system to provide earlier target detection than the FLAP LID radar allows. It can detect a missile-sized target flying at an altitude of 60 metres (200 ft) at least 20 km (12 mi) away, at an altitude of 100 m (330 ft) at least 30 km (19 mi) away, and at high altitude up to 175 km (109 mi) away. In addition a 64N6 BIG BIRD E/F band target acquisition radar can be used which has a maximum detection range of 300 km (190 mi).
