The Buk missile system (Russian: "Бук"; beech, /bʊk/ BOOK) is a family of self-propelled, medium-range surface-to-air missile systems developed by the Soviet Union and its successor state, the Russian Federation, and designed to engage cruise missiles, smart bombs, fixed- and rotary-wing aircraft, and unmanned aerial vehicles.

The Buk missile system is the successor to the NIIP/Vympel 2K12 Kub (NATO reporting name SA-6 "Gainful"). The first version of Buk adopted into service carried the GRAU designation 9K37 and was identified in the west with the NATO reporting name "Gadfly" as well as the US Department of Defense designation SA-11. Since its initial introduction into service the Buk missile system has been continually upgraded and refined. With the integration of a new missile the Buk-M1-2 and Buk-M2 systems also received a new NATO reporting name Grizzly and a new DoD designation SA-17. The latest incarnation "Buk-M3" is scheduled for production.

A naval version of the system, designed by MNIIRE Altair (currently part of GSKB Almaz-Antey) for the Russian Navy, according to Jane's Missiles & Rockets, received the GRAU designation 3S90M1 and will be identified with the NATO reporting name Gollum and a DoD designation SA-N-7C. The naval system is scheduled for delivery in 2014.

Development

Development of the 9K37 "Buk" was started on 17 January 1972 at the request of the Central Committee of the CPSU. The development team comprised many of the same institutions that had been responsible for the development of the previous 2K12 "Kub" (NATO reporting name "Gainful", SA-6). These included the Tikhomirov Scientific Research Institute of Instrument Design (NIIP) as the lead designer and the Novator design bureau who were responsible for the development of the missile armament. In addition to the land based missile system a similar system was to be produced for the naval forces, the result being the 3S90 "Uragan" (Russian: "Ураган"; hurricane) which also carries the SA-N-7 and "Gadfly" designations.

The Buk missile system was designed to surpass the 2K12 Kub in all parameters and its designers including its chief designer Ardalion Rastov visited Egypt in 1971 to see Kub in operation. Both the Kub and Buk used self-propelled launchers developed by Ardalion Rastov. As a result of this visit the developers came to the conclusion that each Buk transporter erector launcher (TEL) should have its own fire control radar rather than being reliant on one central radar for the whole system as in Kub. The result of this move from TEL to transporter erector launcher and radar (TELAR) was a system able to engage multiple targets from multiple directions at the same time.

During development in 1974 it was identified that although the Buk missile system is the successor to the Kub missile system both systems could share some interoperability, the result of this decision was the 9K37-1 Buk-1 system. The advantage of interoperability between Buk TELAR and Kub TEL was an increase in the number of fire control channels and available missiles for each system as well as a faster service entry for Buk system components. The Buk-1 was adopted into service in 1978 following completion of state trials while the complete Buk missile system was accepted into service in 1980 after state trials took place between 1977 and 1979.

The naval variant of the 9K37 "Buk", the 3S-90 "Uragan" was developed by the Altair design bureau under the direction of chief designer G.N. Volgin. The 3S-90 used the same 9M38 missile as the 9K37 though the launcher and associated guidance radars were exchanged for naval variants. The 9S-90 system was tested between 1974–1976 on the Kashin-class destroyer Provorny, and accepted into service in 1983 on the Project 956 Sovremenny-class destroyers.

No sooner than the 9K37 "Buk" had started to enter service than the next phase of its development was put into operation, in 1979 the Central Committee of the CPSU authorised the development of a modernised 9K37 which would become the 9K37M1 Buk-M1, adopted into service in 1983. The modernisation improved the performance of the systems radars, kill probability and resistance to electronic countermeasures (ECM). Additionally a non-cooperative threat classification system was installed, allowing targets to be classified without IFF via analysis of return radar signals. The export version of Buk-M1 missile system is known as "Gang" (Russian: "Ганг"; Ganges) .

Another modification to the Buk missile system was started in 1992 with work carried out between 1994 and 1997 to produce the 9K37M1-2 Buk-M1-2, which was accepted into service in 1998. This modification introduced a new missile, the 9M317 which offered improved kinematic performance over the previous 9M38 which could still be used by the Buk-M1-2. Such sharing of the missile type caused a transition to a different GRAU designations – 9K317 which has been used independently for all later systems. The previous 9K37 series name was also preserved for the complex as was the "Buk" name. The new missile as well as a variety of other improvements allowed the system to intercept ballistic missiles and surface targets as well as offering improved performance and engagement envelope against more traditional targets like aircraft and helicopters. The 9K37M1-2 Buk-M1-2 also received a new NATO reporting name distinguishing it from previous generations of the Buk system, this new reporting name was the SA-17 Grizzly. The export version of the 9K37M1-2 system is called "Ural" (Russian: "Урал")

The introduction of the 9K37M1-2 system for the land forces also marked the introduction of a new naval variant, the "Ezh" which carries the NATO reporting name SA-N-7B 'Grizzly' (9M317 missile) and was exported under the name "Shtil" and carries a NATO reporting name of SA-N-7C 'Gollum' (9M317E missile), according to Jane's catalogue. The 9K317 incorporates the 9M317 missile to replace the 9M38 used by the previous system. A further advancement of the system was unveiled as a concept at EURONAVAL 2004, a vertical launch variant of the 9M317, the 9M317ME, which is expected to be exported under the name 3S90E "Shtil-1". Jane's also reported that in the Russian forces it would have a name of 3S90M "Smerch" (Russian: "Смерч", English translation: 'tornado').

The Buk-M1-2 modernisation was based on a previous far more advanced developmental system referred to as the 9K317 "Buk-M2". This modernisation not only featured new missiles but also included a new third generation phased array fire control radar allowing engagement of up to four targets while tracking a further 24. A new radar system was also developed which carried a fire control radar on a 24 meter extending boom, improving performance against targets flying at low altitude. This new generation of Buk missile systems was stalled due to the poor economic conditions after the fall of the Soviet Union, however the system was recently presented as a static display at 2007 MAKS Airshow. The export version of the Buk-M2 missile system Buk-M2E is also known as Ural (Russian: Урал; English: Ural) .

In October 2007, Russian General Nikolai Frolov, commander of the Ground Forces' air defense, declared that the Russian Army would receive the brand-new Buk-M3 to replace the Buk-M1. He stipulated that the M3 would feature advanced electronic components and enter in service in 2009. Upgraded Buk-M3 TELAR will have a seven rollers tracked chassis and a 6 missiles in a launch tubes.

Description

Inside the TELAR of a Buk-M1 SAM system

A standard Buk battalion consists of a command vehicle, target acquisition radar (TAR) vehicle, six transporter erector launcher and radar (TELAR) vehicles and three transporter erector launcher (TEL) vehicles. A Buk missile battery consists of two TELAR and one TEL vehicle. The battery requires no more than 5 minutes to set up before it is ready for engagement and can be ready for transit again in 5 minutes. The reaction time of the battery from target tracking to missile launch is around 22 seconds.

Inside the TEL of a Buk-M1-2 SAM system

The Buk-M1-2 TELAR uses the GM-569 chassis designed and produced by JSC MMZ (Mytishchi). TELAR superstructure is a turret containing the fire control radar at the front and a launcher with four ready-to-fire missiles on top. Each TELAR is operated by a crew of four and is equipped with CBRN protection. The radar fitted to each TELAR, referred to as the 'Fire Dome' by NATO, is a monopulse type radar and can begin tracking at the missile's maximum range (32 km/20 mi) and can track aircraft flying at between 15 m and 22,000 m (50 to 72,000 ft) altitudes. It can guide up to three missiles against a single target. The 9K37 system supposedly has much better ECCM characteristics (i.e. is more resistant to ECM and jamming) than the 3M9 Kub system that it replaces. While early Buk had a day radar tracking system 9Sh38 (similar was used for example on Kub, Tor and Osa missile system), its current design can be fitted with a combined optical tracking system with a thermal camera and a laser range-finder for passive tracking of the target. The 9K37 system can also utilise the same 1S91 Straight Flush 25 kW G/H band continuous wave radar as the 3M9 "Kub" system.

The 9S35 radar of the original Buk TELAR uses mechanical scan of Cassegrain antenna reflector. Buk-M2 TELAR design used a PESA for tracking and missile guidance.

The 9K37 utilises the 9S18 "Tube Arm" or 9S18M1 (which carries the NATO reporting name "Snow Drift") (Russian: СОЦ 9C18 "Купол"; dome) target acquisition radar in combination with the 9S35 or 9S35M1 "Fire Dome" H/I band tracking and engagement radar which is mounted on each TELAR. The Snow Drift target acquisition radar has a maximum detection range of 85 km (53 mi) and can detect an aircraft flying at 100 m (330 ft) from 35 km (22 mi) away and even lower flying targets at ranges of around 10–20 km (6–12 mi). Snow Drift is mounted on a chassis similar to that of the TELAR, as is the command vehicle. The control post which coordinates communications between the surveillance radar(s) and the launchers is able to communicate with up to six TELs at once.

Console of the upgraded TELAR of a Buk-M2E

The TEL reload vehicle for the Buk battery resembles the TELAR but instead of a radar they have a crane for loading missiles. They are capable of launching missiles directly but require the cooperation of a Fire Dome-equipped TELAR for missile guidance. A reload vehicle can transfer its missiles to a TELAR in around 13 minutes and can reload itself from stores in around 15 minutes.

Also, Buk-M2 featured a new vehicle like TELAR, but with radar on top of a telescopic lift and without the missiles called a target acquisition radar (TAR) 9S36. This vehicle could be used together with two TELs 9A316 to engage up to four targets, missile guidance in the forest or hill regions.

All vehicles of Buk-M1 (Buk-M1-2) missile system uses an Argon-15A computer as Zaslon radar does (the first airborne digital computer designed in 1972 by the Soviet Research Institute of Computer Engineering (NICEVT, currently NII Argon) and produced at "Kishinev plant of 50 Years of USSR". The vehicles of Buk-M2 (Buk-M2E) missile system use a slightly upgraded version of Argon-A15K. This processor is also used in such military systems as anti-submarine defense Korshun and Sova, airborne radars for MiG-31 and MiG-33, mobile tactical missile systems Tochka, Oka and Volga. Currently, Argons are upgraded into Baget series of processors by NIIP.

Integration with higher level command posts

The basic command post of Buk missile system is 9С510 (9K317 Buk-M2), 9S470M1-2 (9K37M1-2 Buk-M1-2) and 9S470 (Buk-M1) vehicle organizing the Buk system into battery. It is capable of linking with various higher level command posts (HLCPs).

As an option it could be combined into the brigade with the use of HLCP, but not mixing into a unified battery.

Buk missile system may be controlled by an upper level command post system 9S52 Polyana-D4 integrating it with S-300V/S-300VM into an air defence brigade. Also it may be controlled by an upper level command post system 73N6ME «Baikal-1ME» together with 1-4 units of PPRU-M1 (PPRU-M1-2), integrating it with SA-19 "Grison" (9K22 Tunguska) (6-24 units total) into an air defence brigade. With the use of the mobile command center Ranzhir or Ranzhir-M (GRAU designations 9S737, 9S737М) Buk missile system allows to create a mixed groups of air defense forces, including Tor, Tungushka, Strela-10, and Igla. "Senezh" is other optional command post for a free mixing the of any systems.

3S90 "Uragan"

3S90E "Shtil" (export version of M-22 Uragan) on INS Talwar (F40)

The 3S90 "Uragan" (Russian: Ураган; hurricane) is the naval variant of the 9K37 "Buk" and has the NATO reporting name "Gadfly" and US DoD designation SA-N-7, it also carries the designation M-22. The export version of this system is known as "Shtil" (Russian: Штиль; still). The 9М38 missiles from the 9K37 "Buk" are also used on the 3S90 "Uragan". The launch system is different with missiles being loaded vertically onto a single arm trainable launcher, this launcher is replenished from an under-deck magazine with a 24 round capacity, loading takes 12 seconds to accomplish. The Uragan utilises the MR-750 Top Steer D/E band as a target acquisition radar (naval analogue of the 9S18 or 9S18M1) which has a maximum detection range of 300 km (190 mi) depending on the variant. The radar performing the role of the 9S35 the 3R90 Front Dome H/I band tracking and engagement radar with a maximum range of 30 km (19 mi).

3S90 "Ezh"

The modernised version of the 3S90 the 9K37M1-2 (or 9K317E) "Ezh" which carries the NATO reporting name "Grizzly" or SA-N-12 and the export designation "Shtil" was developed which uses the new 9M317 missile. This variant was supposed to be installed on Soviet Ulyanovsk-class nuclear aircraft carriers, and has been retrofitted to the Sovremenny-class destroyers..

In 1997, India signed a contract for the three Project 1135.6 frigates with "Shtil". Later, when the decision was made to modernize it with a new package of hardware & missiles, the name changed to "Shtil-1".

3S90M "Shtil-1"

In 2004, the first demonstration module of the new 9M317ME missile was presented by Dolgoprudniy Scientific and Production Plant for the upgraded 3S90M "Shtil-1" naval missile system (jointly with 'Altair'). Designed primary for the export purpose, its latest variant used a vertical launch missile which is fired from under-deck silos clustered into groups of twelve, twenty-four or thirty-six. The first Shtil-1 systems were installed into ships exported to India and China. Old systems Uragan, Ezh and Shtil could be upgraded to Shtil-1 by replacing the launcher module inside the ship.

9М38 and 9М38M1 missile

The 9M38 uses a single-stage X-winged design without any detachable parts; its exterior design is similar to the American Tartar and Standard surface-to-air missile series, which led to half-serious nickname of Standardski. The design had to conform to strict naval dimension limitations, allowing the missile to be adapted for the M-22 SAM system in the Soviet Navy. Each missile is 5.55 m (18 feet) long, weighs 690 kg (1521 lb) and carries a relatively large 70 kg (154 lb) warhead which is triggered by a radar proximity fuze. In the forward compartment of the missile, a semi-active homing radar head (9E50, Russian: 9Э50, 9Э50М1), autopilot equipment, power source and a warhead is located. The homing method chosen was proportional navigation. Some elements of the missile were compatible with the Kub's 3M9; for example, its forward compartment diameter (33 cm), which was less than the rear compartment diameter.

9M317 surface-to-air missile on the Buk-M2 quadruple launcher.

The 9M38 surface-to-air missile utilizes a two-mode solid fuel rocket engine with total burn time of about 15 seconds; the combustion chamber is reinforced by metal. For the purpose of reducing the centering dispersion while in flight, the combustion chamber is located close to the center of the missile and includes a longer gas pipe. Rejection of a direct-flow engine type was explained by its instability on a large angle of attack and by a larger air resistance on a passive trajectory section as well as by some technical difficulties. Those difficulties already wrecked the plans to create the missile for Kub. The design of 9M38 ensures its readiness without inspection for at least 10 years of service and is delivered to the army in the 9Ya266 (9Я266) transport container.

It has been suggested that the Novator KS-172 AAM-L, an extremely long range air-to-air missile and possible anti-satellite weapon, is a derivative of the 9M38.

9M317 missile

The 9M317 exterior design bears a resemblance to the Vympel R-37 air-to-air missile.

The 9M317 missile was developed as a common missile for the Ground Forces PVO (Buk-M1-2) as well as for ship-based PVO of the Russian Navy (Ezh)

The unified multi-functional missile 9M317 (export designation 9M317E) can be used to engage modern and perspective aerodynamic, ballistic, above-water and radio contrast targets with the air defence complexes of land and naval forces. It was designed by OJSC Dolgoprudny Scientific Production Plant (DNPP) and passed the full cycle of ground and flight testing on different complexes and weapon systems. Testing included targets analogues of tactical ballistic missiles, strategic cruise missiles, anti-ship missiles, tactical, strategic and army aircraft and helicopters. The maximum engagable target speed was 1200 m/s, the missile could tolerate an acceleration overload of 24G. Missile was first used with Buk-M1-2 system of the land forces and the Shtil-1 system of the naval forces.

It may engage the tactical ballistic missiles, strategic and tactical aircraft manoeuvring up to 12G, cruise missiles, fire support helicopters (including hovering low above the ground), remotely controlled aircraft, anti-ship missiles in a heavy anti-radiation environment and radiocontrast targets above water and above the ground.

In comparison with 9M38M1, the 9M317 missile has a larger defeat area, which is up to 45 km of range and 25 km of altitude and of lateral parameter, and a larger target classification. On the outer view 9M317 differs from 9M38M1 by a smaller wing chord. It uses the inertial correction control system with semi-active radar homing, utilising the proportional navigation (PN) targeting method.

Semi-active homing radar head of a missile (9E420, Russian: 9Э420) as well as 9E50M1 for 9M38M1 missile (9E50 for 9M38) and 1SB4 for Kub missile (Russian: 1СБ4) was designed by MNII Agate (Zhukovskiy) and manufactured by MMZ at Ioshkar-Ola.

9M317M and 9M317A missile projects

Currently, several modernized versions are in development, including the 9M317M, it is export version the 9M317ME and the active radar homing (ARH) missile project 9M317A with its export version the 9M317MAE.

The lead developer, NIIP, reported about the 9M317A missile testing within Buk-M1-2A "OKR Vskhod" (Sprout in English) program in 2005. Range is reported as being up to 50 km (31 mi), maximum altitude around 25 km (82,000 ft) and maximum target speed around Mach 4. The weight of the missile has increased slightly to 720 kg (1587 lb).

Vskhod development program of the new missile for the air defence missile system Buk-M1-2A was completed in 2011. This missile could increase the survival capability and firing performance of the Buk-M1-2A missile system, have a feature to hit the targets behind the skyline in process of in-flight guidance.

In 2011 Dolgoprudny NPP completed preliminary trials of the new autonomous target missile system OKR Pensne (pince-nez in English) developed from earlier missile.

9M317ME missile

The weight of the missile is 581 kg, including the 62 kg blast fragmentation warhead initiated by a dual-mode radar proximity fuze. Dimensions of the hull are 5.18 m length; 0.36 m maximum diameter. Range is 2.5–32 km in a 3S90M "Shtil-1" naval missile system. Altitude of targets from 15 m up to 15 km (and from 10 m to 10 km against other missiles). The 9M317ME missiles can be fired at 2-second intervals, while its reaction (readiness) time is up to 10 s.

Missile was designed to be single-staged, semi-active radio command radar homing with inertial guidance.

The tail surfaces have a span of 0.82 m when deployed after the missile leaves the launch container by a spring mechanism. Four gas-control vanes operating in the motor efflux turn the missile towards the required direction of flight. After the turnover manoeuvre, they are no longer used and subsequent flight controlled via moving tail surfaces. A dual-mode solid-propellant rocket motor provides the missile with a maximum speed of Mach 4.5.

Copies

• Belarus – In May on the MILEX-2005 exposition in Minsk, Belarus presented their own modification of 9K37 Buk called Buk-MB. On 26 June 2013 an exported version of Buk-MB was displayed on a military parade in Baku. It included the new 80K6M Ukrainian-build radar on an MZKT chassis (instead the old 9S18M1) and the new Russian-build missile 9M317 (as in Buk-M2).
• People's Republic of China – HQ-16 (Hongqi-16) - People's Republic of China project based on the naval 9K37M1-2 system 'Shtil' (SA-N-12). Other sources also rumored the project involved some Buk technology. It is able to engage high altitude and very low flying targets. The most visual distinction between SA-17 and HQ-16 is that the latter is truck-based and vertically launched instead of track based SA-17, its range increased to 70 kilometers, and the firepower is increased by 50% with the total number of missiles increased to six from the original four in SA-17 system.
  • People's Republic of China – HQ-16A – Improvement of the HQ-16, with redesigned control surfaces incorporating leading edge, thus has better performance at higher angle of attack than HQ-16.
  • People's Republic of China – HQ-16B – Further improvement of HQ-16A
  • People's Republic of China – LY80 – Export version of HQ-16A, incorporating cold vertical launch method
• Iran – Raad Medium Ranged Surface-to-Air Missile System using Ta'er 2 missiles. It has very similar layout to wheeled Buk-M2EK 9M317. It was shown during 2012 military parade.

In 1996 Finland started operating the eighteen missile systems that they received from Russia as debt payment. According to Suomen Kuvalehti, Finland is planning to accelerate the replacement of the missile system due to concerns about its susceptibility to electronic warfare.

Combat service

Abkhaz authorities claimed that Buk air defense system was used to shoot down four Georgian drones at the beginning of May 2008.

Analysts stipulated that Georgian Buk missile systems were responsible for downing four Russian aircraft—three Sukhoi Su-25 close air support aircraft and a Tupolev Tu-22M strategic bomber—in the 2008 South Ossetia war. U.S. officials have said Georgia's SA-11 Buk-1M was certainly the cause of the Tu-22M's loss and contributed to the losses of the three Su-25s. According to some analysts, the loss of four aircraft is surprising and a heavy toll for Russia given the small size of Georgia's military. Some have also pointed out, that Russian electronic counter-measures systems were apparently unable to jam and suppress enemy SAMs in the conflict and that Russia was, surprisingly, unable to come up with effective countermeasures against missile systems it had designed.

Georgia bought these missile systems from Ukraine which had an inquiry to identify if the purchase was illegal.

On 29 January 2013, the Israeli Air Force launched an airstrike on a convoy in Syria believed to have SA-17 BUK-M2E missiles bound for Hezbollah in Lebanon. The Syrian government denied that the shipment of weapons was taking place.

The system is suspected of having been involved in the crash of a Malaysian Airlines 777 on 17 July 2014 in airspace controlled by Ukrainian separatist forces killing all 295 aboard. Videos posted by separatist forces just after the crash claimed to have used the system to down an aircraft in the area of the crash, and showed videos of the burning wreckage in the distance as evidence.
