The S-300 is a series of Russian long range surface-to-air missile systems produced by NPO Almaz, all 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 was jointly produced by Almaz with Samsung Group of South Korea since 1993.
The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defense of large industrial and administrative facilities, military bases, and control of airspace against enemy strike aircraft.
The project-managing developer of the S-300 is Russian Almaz corporation (government owned, aka "KB-1") which is currently a part of "Almaz-Antei" Air Defense Concern. S-300 uses missiles developed by MKB "Fakel" design bureau (a separate government corporation, aka "OKB-2").
The S-300 is regarded as one of the most potent anti-aircraft missile systems currently fielded. Its radars have the ability to simultaneously track up to 100 targets while engaging up to 12. S-300 deployment time is five minutes. The S-300 missiles are sealed rounds and require no maintenance over their lifetime. An evolved version of the S-300 system is the S-400 (NATO reporting name SA-21), entering limited service in 2004.
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.
S-300 system family tree
S-300P
Land-based S-300P (SA-10)
The S-300P (transliterated from Russian С-300П, NATO reporting name SA-10 Grumble) is the original version of the S-300 system which became operational in 1978. In 1987 over 80 of these sites were active, mainly in the area around Moscow. The P suffix stand for PVO-Strany (country air defence system). An S-300PT unit consists of a 36D6 (NATO reporting name TIN SHIELD) surveillance radar, a 30N6 (FLAP LID) fire control system and 5P85-1 launch vehicles. The 5P85-1 vehicle is a semi-trailer truck. Usually a 76N6 (CLAM SHELL) low altitude detection radar is also a part of the unit.
This system broke substantial new ground, including the use of a phased array radar and multiple engagements on the same Fire-control system (FCS). Nevertheless, it had some limitations. It took over one hour to set up this semi-mobile system for firing and the hot vertical launch method employed scorched the TEL.
It was originally intended to fit the Track Via Missile (TVM) guidance system onto this model. However, the TVM system had problems tracking targets below 500 m. Rather than accept the limitation, the Soviets decided that the tracking of low altitude targets was a must and decided to use a pure command-guidance system until the TVM head was ready. This allowed the minimum engagement altitude to be set at 25 m.
Improvements to the S-300P have resulted in several major subversions for both the internal and the export market. The S-300PT-1 and S-300PT-1A (SA-10b/c) are incremental upgrades of the original S300PT system. They introduce the 5V55KD missile and the cold launch method thereafter employed. Time to readiness was reduced to 30 minutes (broadly comparable to Patriot) and trajectory optimizations allowed the 5V55KD to reach a range of 75 km.
The S-300PS/S-300PM (Russian С-300ПC/С-300ПМ, NATO reporting name SA-10d/e) was introduced in 1985 and is the only version thought to have been fitted with a nuclear warhead. This model saw the introduction of the modern TEL and mobile radar and command-post vehicles that were all based on the MAZ-7910 8x8 truck. This model also featured the new 5V55R missiles which increased maximum engagement range to 90 km (56 mi) and introduced a terminal semi-active radar homing (SARH) guidance mode. The surveillance radar of these systems was designated 30N6. Also introduced with this version was the distinction between self propelled and towed TELs. The towed TEL is designated 5P85T. Mobile TELs were the 5P85S and 5P85D. The 5P85D was a "slave" TEL, being controlled by a 5P85S "master" TEL. The "master" TEL is identifiable thanks to the large equipment container behind the cabin; in the "slave" TEL this area is not enclosed and is used for cable or spare tyre storage.
The next modernisation, called the S-300PMU (Russian С-300ПМУ, US DoD designation SA-10f) was introduced in 1992 for the export market and featured the upgraded 5V55U missile which still utilised the intermediate SARH terminal guidance method and smaller warhead of the 5V55R but increased the engagement envelope to give this missile roughly the same range and altitude capabilities as the newer 48N6 missile (max. range 150 km/93 mi). The radars were also upgraded, with the surveillance radar for the S-300PMU being designated 64N6 (BIG BIRD) and the illumination and guidance radar being designated 30N6-1 in the GRAU index.
S-300F
Sea-based S-300F (SA-N-6)
The S-300F Fort (Russian С-300Ф Форт, DoD designation SA-N-6, F suffix for Flot, Russian for fleet) was introduced in 1984 as the original ship-based (naval) version of the S-300P system developed by Altair with the new 5V55RM missile with range extended to 7–90 km (4-56 mi, equal to 3.8-50 nautical miles) and maximum target speed up to Mach 4 while engagement altitude was reduced to 25-25,000 m (100-82,000 ft). The naval version utilises the TOP SAIL or TOP STEER, TOP PAIR and 3R41 Volna (TOP DOME) radar and utilises command guidance with a terminal semi-active radar homing (SARH) mode. Its first installation and sea trials were on a Kara class cruiser and it is also installed on Slava class cruisers and Kirov class battlecruisers. It is stored in eight (Slava) or twelve (Kirov) 8-missile rotary launchers below decks. The export version of this system is known as Rif (Russian Риф — reef). The NATO name, found also in colloquial use, is "Grumble".
Sea-based S-300FM (SA-N-20)
The S-300FM Fort-M (Russian С-300ФМ, DoD designation SA-N-20) is another naval version of the system, installed only on the Kirov class cruiser RFS Pyotr Velikiy, and introduced the new 48N6 missile. It was introduced in 1990 and increased missile speed to approximately Mach 6 for a maximum target engagement speed of up to Mach 8.5, increased the warhead size to 150 kg (330 lb) and increased the maximum engagement range yet again to 5–150 km (3-93 mi) as well as opening the altitude envelope to 10m-27 km (33–88500 ft). The new missiles also introduced the ultimate track-via-missile guidance method and brought with it the ability to intercept short-range ballistic missiles. This system makes use of the TOMB STONE MOD rather than TOP DOME radar. The export version is called the Rif-M. Two Rif-M systems were purchased by China in 2002 and installed on the Type 051C air-defence guided missile destroyers.
Both naval versions are believed to include a secondary infrared terminal seeker, similar to the newer US Standard missile system, probably to reduce the system's vulnerability to saturation. This also allows the missile to engage contacts over the radar horizon, such as warships or sea-skimming anti-ship missiles.
S-300V (SA-12)
The 9K81 S-300V Antey-300 (Russian 9К81 С-300В Антей-300 - named after Antaeus, NATO reporting name SA-12 Gladiator/Giant) is a bit different from the other versions. It was built by Antey as opposed to Almaz. The V suffix stands for Voyska (ground forces). It was designed to act as the top tier army air defence system, providing a defence against ballistic missiles, cruise missiles and aircraft, replacing the SA-4 'Ganef'. The "GLADIATOR" missiles have a maximum engagement range of around 75 km (47 miles) while the "GIANT" missiles can engage targets out to 100 km (62 miles) and up to altitudes of around 32 km (100,000 ft). In both cases the warhead is around 150 kg (331 lb).
While it was created from the same project (hence the common S-300 designation) different priorities resulted in a design quite different from the other versions. The S-300V system is carried on tracked MT-T transporters, which gives it better cross-country mobility than even the S-300Ps on 8x8 wheeled transporters. It is also somewhat more distributed than the S-300P's. For example, while both have mechanically-scanned radar for target acquisition (9S15 BILL BOARD A), the battery level 9S32 GRILL PAN has autonomous search ability and SARH delegated to illumination radar on TELARs. The early 30N6 FLAP LID on the S-300P handles tracking and illumination, but is not equipped with autonomous search (later upgraded).
The S-300V places a greater emphasis on ABM, with the dedicated 9M83 (SA-12B Giant). This missile is larger and only two can be held on each TELAR. It also has a dedicated ABM radar - the 9S19 HIGH SCREEN phased array radar at battalion level. A typical S-300V battalion is made up out of a target detection and designation unit, a guidance radar and up to 6 TELARs. The detection and designation unit consists of the 9S457-1 command post, a 9S15MV or 9S15MT BILL BOARD all-round surveillance radar and 9S19M2 HIGH SCREEN sector surveillance radar. The S-300V uses the 9S32-1 GRILL PAN multi-channel guidance radar. Four types of TELARs can be used with the system. The 9A83-1 which holds 4 9M83 GLADIATOR missiles and the 9A82 which holds 2 9M82 GIANT missiles are pure launchers, while the 9A84 (4× 9M83 GLADIATOR missile) and 9A85 (2× 9M82 GIANT missile) are loaders/launchers.
S-300V system may be controlled by a upper level command post system 9S52 Polyana-D4 integrating it with Buk missile system into a brigade.
S-300PMU-1/2 (SA-20)
The S-300PMU-1 (Russian С-300ПМУ-1,US DoD designation SA-20A, NATO reporting name SA-20 Gargoyle) was also introduced in 1992 with the new and larger 48N6 missiles for the first time in a land-based system and introduced all the same performance improvements from the S300FM version including the increased speed, range, TVM guidance and ABM capability. The warhead is slightly smaller than the naval version at 143 kg (315 lb). This version also saw the introduction of the new and more capable 30N6E TOMB STONE radar.
The S-300PMU-1 was introduced in 1999 and for the first time introduces several different kinds of missiles in a single system. In addition to the 5V55R, 48N6E and 48N6E2 missiles the S-300PMU-1 can utilise two new missiles, the 9M96E1 and 9M96E2. Both are significantly smaller than the previous missiles at 330 and 420 kg (728 and 926 lb respectively) and carry smaller 24 kg (53 lb) warhead. The 9M96E1 has an engagement range of 1–40 km (1-25 mi) and the 9M96E2 of 1–120 km (1-75 mi). They are still carried 4 per TEL. Rather than just relying on aerodynamic fins for manoeuvring, they use a gas-dynamic system which allows them to have an excellent probability of kill (Pk) despite the much smaller warhead. The Pk is estimated at 0.7 against a tactical ballistic missile for either missile. The S-300PMU-1 typically uses the 83M6E command and control system, although it is also compatible with the older Baikal-1E and Senezh-M1E CCS command and control systems. The 83M6E system incorporates the 64N6E (BIG BIRD) surveillance/detection radar. The fire control/illumination and guidance radar used is the 30N6E(1), optionally matched with a 76N6 low altitude detection radar and a 96L6E all altitude detection radar. The 83M6E command and control system can control up to 12 TELs, both the self propelled 5P85SE vehicle and the 5P85TE towed launchers. Generally support vehicles are also included, such as the 40V6M tow vehicle, intended for lifting of the antenna post.
The S-300PMU-2 Favorite (Russian С-300ПМУ-2 Фаворит – Favourite, DoD designation SA-20B), introduced in 1997, is an upgrade to the S-300PMU-1 with range extended once again to 195 km (121 mi) with the introduction of the 48N6E2 missile. This system is apparently capable against not just short range ballistic missiles, but now also medium range tactical ballistic missiles. It uses the 83M6E2 command and control system, consisting of the 54K6E2 command post vehicle and the 64N6E2 surveillance/detection radar. It employs the 30N6E2 fire control/illumination and guidance radar. Like the S-300PMU-1, 12 TELs can be controlled, with any mix of 5P85SE2 self propelled and 5P85TE2 trailer launchers. Optionally it can make use of the 96L6E all altitude detection radar and 76N6 low altitude detection radar, just like the S-300PMU-1.
S-400 (SA-21)
The S-400 Triumf (Russian С-400 «Триумф», formerly known as the S-300PMU-3/С-300ПМУ-3, NATO reporting name SA-21 Growler) was introduced in 1999 and features a new, much larger missile with 2 per TEL. The project has been encountering delays since its original announcement and deployment has only begun on a small scale in 2006. With an engagement range of up to 400 km (250 mi), depending on the missile variant used, and specifically designed to counter stealth it is by far the most advanced version. Little else is known about this version.
