2K12 Kub Russian SAM

The 2K12 "Kub" mobile surface-to-air missile system is a Soviet low to medium-level air defence system designed to protect ground forces from air attack. "2К12" is the GRAU designation of the system. Kub is known in the west by its NATO reporting name "Gainful" as well as the US Department of Defense designation SA-6.

Each 2K12 battery consists of a number of similar tracked vehicles, one of which carries the 1S91 (SURN vehicle, NATO designation "Straight Flush") 25 kW G/H band radar (range 75 km/47 miles) equipped with a continuous wave illuminator, in addition to an optical sight. The battery usually also includes four triple-missile transporter erector launchers (TELs) and four trucks each carrying three spare missiles and a crane. TEL is based on a GM-578 chassis, while the 1S91 radar vehicle on a GM-568, all developed and produced by MMZ.

The 2K12 system shares a lot of components with the 2K11 Krug (SA-4) system. In many ways they are designed to complement each other; 2K11 is effective at long ranges and high altitudes, 2K12 at medium ranges and intermediate altitudes.

The system is able to acquire and begin tracking targets using the 1С91 самоходных установок разведки и наведения ("Self-propelled Installation for Reconnaissance and Guidance" / NATO: "Straight Flush" radar) at 75 km (47 miles) and begin illumination and guidance at 28 km (17 miles). IFF is also performed using this radar. It can only guide one or two missiles to a single target at any time. The missile is initially command guided with terminal semi active radar homing (SARH), with target illumination provided by the "Straight Flush" radar. Detonation is via either the impact or proximity fuze. On the latest models, this vehicle is also fitted with an optical tracking system which allows engagement without the use of the radar (for active RF emissions stealth reasons, or due to heavy ECM jamming) in which case the effective altitude is limited to 14 km/46000 ft. The optical tracking method also allows engagements to altitudes below that where the radar is able to track targets. Maximum target speed is around Mach 2 for head-on engagements and Mach 1 for tail-chase engagements. Top speed of the missile is approximately Mach 2.8.

In contrast to the elaborate Patriot missile or even the simpler Hawk system fielded by US forces, most of the system rides on two tracked self-propelled vehicles, rather than towed or mounted on trucks, and either the launcher or control vehicle can be set to launch in only 15 minutes after changing location.

Missiles

The fairly large missiles have an effective range of 4–24 km (2.5–15 miles) and an effective altitude of 50–14000 m (164–45,931 ft). The missile weighs 599 kg (1321 lb) and the warhead weighs 56 kg (123 lb). Top missile speed is approx. Mach 2.8. The combined propulsion system 9D16K included solid fuel rocket motor which, when burned out, forms the combustion chamber for a ramjet in a pioneering design putting this missile far ahead of its contemporaries in terms of propulsion.

The missile was fitted with a semi-active radar seeker 1SB4, designed by MNII Agat, which was able to track the target by Doppler frequency since the start. Chief Designer of the seeker head was Yu.N. Vekhov, since 1960 - I.G. Akopyan.

In 1977 a new version, the 3M9M1 (DoD designation SA-6B) was created with three missiles fitted onto a different chassis (the same as that of the 9K37 "Buk" (NATO reporting name "Gadfly" / DoD SA-11 ), the 2K12 effective replacement) with an integrated "Fire Dome" missile guidance radar. For comparisons between the 2K12, 9K37, see the 9K37 Buk entry.

An earlier incremental upgrade saw the 2K12 missiles replaced with the 2K12E versions and this system was known as Kvadrat ("Квадрат", meaning square). This name was derived from the most common arrangement pattern of the military vehicles of the 2K12 complex, when the 1C91 radar is located at the center and 4x2P25 TELs at the vertices of a square around the radar.

1S91 radar

SURN 1S91 vehicle included two radar station - a target acquisition and distribution radar 1S11 and a continuous wave illuminator 1S31, in addition to an IFF interrogator and an optical channel.

While 1S31 antenna was installed on the upper section of the superstructure and the 1S11 on the lower, they could turn around independently. To make the height of the vehicle lower the central cylinder was able to hide inside the prime mover.

The acquisition range of the radar was reported as 50 km (31 mi) for the Phantom II type target.

Total weight of the 1S91 vehicle with a crew of 4 was 20.3 tonnes and 2P25 vehicle with 3 missiles and a crew of 3 was 19.5 t.

Additional radar

The 2K12 can also be used at a regimental level, if used as such it can be accompanied by a number of additional radar systems for extended air search at longer range and lower altitude, to supplement the 1S91 "Straight Flush". These systems include the:

  • P-12 "Spoon Rest", a VHF early warning radar (also used by the SA-2), with a 200 kilometres (120 mi) range.
  • P-40 "Long Track", an E band early warning radar (also used by the SA-4 and SA-8, with a 370 kilometres (230 mi) range.
  • P-15 "Flat Face A", a UHF early warning radar (also used by the SA-3, with a 150 kilometres (93 mi) range.
  • "Thin Skin" or "Side Net" E band height finding radar (also used by the SA-2, SA-4 and SA-5, range 240 km/148 miles)
  • "Score Board" IFF radar

The "Spoon Rest" and "Thin Skin" are mounted on a truck, "Long Track" on a tracked vehicle (a modified AT-T) and "Flat Face" on a van. It is unknown what kind of mounting the "Score Board" has.

Without the P-40 "Long Track" mobile radar vehicle, the 2K12 is unable to track aircraft at high altitudes.

2K11 Krug Transportable SAM system

The 2K11 Krug is a Soviet and now Russian long range, medium-to-high altitude surface-to-air missile (SAM) system. "2K11" is its GRAU designation, while SA-4 Ganef is its NATO reporting name. The system was designed by NPO Novator and produced by Kalinin Machine Building Plant.

Vehicles

The TEL vehicles are tracked (modified AT-Ts) based on a GM-123 chassis and carry two missiles each on an elevating turntable for up to 360 degree rotation and 70 degree elevation. The two primary versions of the missile in service are the 9M8M1 (2K11M "Krug-M") and 9M8M2 (2K11M2/3 "Krug-M1"), both of which are believed to be known to the US DoD as SA-4B. The original 9M8M (SA-4A) was first introduced into service in 1965 and followed by the upgraded 9M8M1 (2K11A "Krug-A") in 1967 before the 9M8M1 in 1971 and the 9M8M2 in 1973. The 9M8M2 actually has a lower maximum engagement altitude and shorter range in exchange for better performance in engaging aircraft close to the battery. Each battery typically consists of two 9M8M1 missiles and four 9M8M2 missiles as well as the following radars:

  • P-40 "Long Track" E-band early warning radar (also used by the SA-6 and SA-8, range 175 km/108 miles)
  • "Pat Hand" H-band continuous wave fire control and guidance radar (range 128 km/80 miles)
  • "Thin Skin" E-band height finding radar (also used by the SA-6 and SA-8, range 240 km/148 miles)

Both "Long Track" and "Pat Hand" are mounted on a modified AT-T vehicle, similar to the 9M8 launch vehicles. "Thin Skin" is mounted on a truck. Batteries may also feature Ural trucks carrying spare missiles for reloading the launchers.

Missile

The 2K11 Krug missiles are launched with the aid of four solid fuel rocket motors inside boosters attached to the outside of the massive missile. Once they have burned and the missile is aloft, it fires a liquid-fuelled ramjet sustainer engine. It reaches speeds of up to Mach 4 and has an effective range of 50–55 km (31–34 miles) depending upon the version. It carries a 135 kg (300 lb) warhead. Possible engagement altitudes range from 100 m-27 km (330-88,500 feet). 3M8 missile was designed and produced by NPO Novator.

Missile guidance is via radio command with a terminal semi-active radar homing (SARH) phase. Optical tracking is possible for the initial command guidance stage in a heavy ECM environment.

Akash Indian SAM

Akash Missile is India's medium range surface-to-air missile defense system developed by the Defence Research and Development Organisation (DRDO) and Bharat Electronics Limited(BEL) as part of the Integrated Guided Missile Development Program. The missile can target aircraft up to 30 km away, at altitudes up to 18,000 m. Akash can be fired from both tracked and wheeled platforms. Akash is said to be capable of both conventional and nuclear warheads, with a reported payload of 60 kg. A nuclear warhead could potentially give the missile the capability to destroy both aircraft and warheads from ballistic missiles. The missile battery is described as being able to track and attack several targets simultaneously.

An Akash battery comprises four 3D phased array radars and four launchers with three missiles each, all of which are interlinked. Each radar is able to track 16 targets simultaneously and control a launcher with 3 missiles. Hence it is reported to be able to detect 100 and track 64 targets and simultaneously attack any 8 of those targets at one time. The Akash system is comparable to the Patriot system, but unlike the Patriot, Akash is fully mobile and capable of protecting a moving convoy of vehicles. Like the Patriot, the Akash is really an air defence SAM which has been tested in a ballistic missile role. The system provides air defence missile coverage of 2,000 km².

The India military's combined orders of the Akash, including radar systems(WLR and Surveillance), have a total worth of $5.2 billion (Indian Rupee ₹ 23,300 crore).

Missile

Akash is a surface-to-air missile with an intercept range of 30 km. It has a launch weight of 720 kg, a diameter of 35 cm and a length of 5.78 metres. Akash flies at supersonic speed, reaching around Mach 2.5. It can reach an altitude of 18 km and can be fired from both tracked and wheeled platforms. An on-board guidance system coupled with an actuator system makes the missile maneuverable up to 15g loads and a tail chase capability for end game engagement. A digital proximity fuse is coupled with a 55 kg pre-fragmented warhead, while the safety arming and detonation mechanism enables a controlled detonation sequence. A self-destruct device is also integrated. It is propelled by an Integrated Ramjet Rocket Engine. The use of a ramjet propulsion system enables sustained speeds without deceleration throughout its flight. The Missile has command guidance in its entire flight.

The design of the missile is somewhat similar to that of the SA-6 with four long tube ramjet inlet ducts mounted mid-body between wings. For pitch/yaw control four clipped triangular moving wings are mounted on the mid-body. For roll control four inline clipped delta fins with ailerons are mounted before the tail. However, the internal schema shows a different layout with an onboard digital computer, no Semi-active seeker, different propellant, different actuators and command guidance datalinks. The Akash carries an onboard radio-proximity fuse.

System

Each Akash battery consists of four self-propelled Launchers (3 Akash SAMs each), a Battery Level Radar - the Rajendra, and a Command post (Battery Control Centre). Two batteries are deployed as a Squadron (Air Force), while up to four form an Akash Group (Army configuration). In both configurations, an extra Group Control Centre (GCC) is added, which acts as the Command and Control HQ of the Squadron or Group. Based on a single mobile platform, GCC establishes links with Battery Control Centres and conducts air defense operations in coordination with air defense set up in a zone of operations.

For early warning, the GCC relies on the Central Acquisition Radar. However, individual batteries can also be deployed with the cheaper, 2-D BSR (Battery Surveillance Radar) with a range of over 100 km.

Each Akash battery can engage up to four targets. Each battery has four launchers with three missiles each, with each Rajendra able to guide four missiles in total, with a maximum of two missiles per target. Up to a maximum of four targets can be engaged by a typical battery with a single Rajendra if one missile is allotted per target.

Communications between the various vehicles are a combination of wireless and wired links. The entire system is designed to be set up quickly and to be highly mobile for high survivability.

The Akash system can be deployed by rail, road or air.

Radars

The missile is guided by a phased array fire control radar called 'Rajendra' which is termed as Battery Level Radar (BLR) with a tracking range of about 60 km. It can track 64 targets in range, azimuth and height and guide eight missiles simultaneously towards four targets. The Rajendra derivative on a BMP-2 chassis and to be used by the Indian Air Force is known as the Battery Level Radar-II whereas that for the Army, is based on a T-72 chassis and is known as the Battery Level Radar-III.

A single Akash missile has an 88% Probability of kill. Two missiles can be fired, five seconds apart, to raise the Probability of Kill to 98.5%.

Long range target acquisition is performed by the 3D Central Acquisition Radar (3D CAR), which is a long range surveillance radar that can track 150 targets in Track while Scan mode at a range of 180 km.

Platforms

The Army's radar and launchers are based on the T-72 chassis to accompany the Army's fast moving armoured formations. The Air Force versions use a combination of tracked and wheeled vehicle. The Air Force Akash launcher consists of a detachable trailer which is towed by an Ashok Leyland truck, and which can be positioned autonomously. Both the Army and Air Force launchers have three ready-to-fire Akash missiles each. The launchers can slew in both elevation and azimuth.

Propulsion

The Akash ,like the Russian 2K12 Kub (SA-6 Gainful), utilizes an integrated ramjet-rocket propulsion system, which provides thrust for the missile throughout its entire flight. "Because this missile has an integrated ram-rocket, maneuverability is highest. The engine is 'on' throughout the flight. The thrust is on till the missile intercepts the target. Most other surface-to-air missiles, including the U.S. Patriot and the Russian S-300 series, use solid-fuel rocket propulsion.

Mistral France Surface to Air Missile

Mistral is an infrared homing surface-to-air missile manufactured by the European multinational company MBDA missile systems (formerly by Matra BAe Dynamics). Based on the French SATCP (Sol-Air À Très Courte Portée), the portable missile later to become the Mistral began development in 1974. It was initially deployed in 1988 for the first version (S1) and 1997 for the second version (M2).

The basic Mistral missile is used with a man-portable launch unit. There are also launch units that allow the missile to be fired from armoured vehicles, ships or helicopters (such as the Aérospatiale Gazelle, Denel Rooivalk, or Eurocopter Tiger).

The two-missile unit installed on ships is called Simbad. The six-missile version is the Sadral. The newly-launched four-missile version is called Tetral. An evolution of the Simbad is now proposed: Simbad RC. Both Tetral and Simbad RC are remote controlled from the ship's deck.

Mistral entered series production in 1989 and is now deployed by 37 armed forces of 25 countries (eight countries in Europe, eight in the Asia-Pacific, five in South America, three in the Middle East), including Austria, Brazil, Chile, Colombia, Cyprus, Ecuador, Estonia, Finland, France, Hungary, Indonesia, Morocco, New Zealand, Norway, Oman, Pakistan, South Korea, Singapore, South Africa, Spain, and Venezuela.

Over 16,000 missiles have been sold/ordered. Recently, industrial sources said the Royal Thai Navy has placed an order on several units of Sadral/Mistral air defence systems. The deal is said to be worth between €45.7 million – €76.2 million. The systems are to be equipped on the Navy’s two Naresuan class frigates and two newly built Pattani class OPVs (Offshore Patrol Vessel).

S-75 Dvina

The S-75 Dvina is a Soviet-designed, high-altitude, command guided, surface-to-air missile (SAM) system. Since its first deployment in 1957, it has become the most widely-deployed and -used air defense missile in history.

This system first gained fame when an S-75 battery shot down a U-2 overflying the Soviet Union in 1960. Later, North Vietnamese forces used the S-75 extensively during the Vietnam War to defend Hanoi and Haiphong. It has also been locally produced in the People's Republic of China using the names HQ-1 and HQ-2. Other nations have produced so many local variants combining portions of the S-75 system with both indigenously-developed components or third-party systems, that it has become virtually impossible to find a pure S-75 system today.

Site layout

Each battalion will typically have six, semi-fixed, single-rail launchers for their V-750 missiles positioned approximately 60 to 100 m (200 to 330 ft) apart from each other in a hexagonal "flower" pattern, with radars and guidance systems placed in the center. It was this unique "flower" shape that led to the sites being easily recognizable in reconnaissance photos. Typically another six missiles are stored on tractor-trailers near the center of the site.

A current example of a site can be seen here just to the west of the junction to Bosra on the M5 motorway in Syria, south of Damascus. This location covers the borders with both Israel and Jordan, so it is of strategic importance.

Missile

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.

S-75 Dvina Radar

The S-75 typically uses the Spoon Rest early warning radar which has a range of about 275 km (171 mi). The Spoon Rest provides early detection of incoming aircraft, which are then handed off to the acquisition Fan Song radar. These radars, having a range of about 65 km (40 mi), are used to refine the location, altitude, and speed of the hostile aircraft. The Fan Song system consists of two antennas operating on different frequencies, one providing elevation (altitude) information and the other azimuth (bearing) information. Regimental headquarters also include a Spoon Rest, as well as a Flat Face long-range C-band radar and Side Net height-finder. Information from these radars is sent from the regiment down to the battalion Spoon Rest operators to allow them to coordinate their searches. Earlier S-75 versions used a targeting radar known as Knife Rest, which was replaced in Soviet use, but can still be found in older installations.

Major variants

Upgrades to anti-aircraft missile systems typically combine improved missiles, radars, and operator consoles. Usually missile upgrades drive changes to other components to take advantage of the missile's improved performance. Therefore, when the Soviets introduced a new S-75, it was paired with an improved radar to match the missile's greater range and altitude.

  • SA-2A; S-75 Dvina (Двина - Dvina River) with Fan Song-A guidance radar and V-750 or V-750V missiles. Initial deployment began in 1957. The combined missile and booster was 10.6 m (35 ft) long, with a booster having a diameter of 0.65 m (26 in), and the missile a diameter of 0.5 m (20 in). Launch weight is 2,287 kg (5,040 lb). The missile has a maximum effective range of 30 km (19 mi), a minimum range of 8 km (8,000 m), and an intercept altitude envelope of between 450 and 25,000 m (1,480 and 82,000 ft).
  • SA-N-2A; S-75M-2 Volkhov-M (Russian Волхов - Volkhov River): Naval version of the A model fitted to the Sverdlov Class cruiser Dzerzhinski. Generally considered unsuccessful and not fitted to any other ships.
  • SA-2B; S-75 Desna (Russian Десна - Desna River). This version featured upgraded Fan Song-B radars with V-750VK and V-750VN missiles. This second deployment version entered service in 1959. The missiles were slightly longer than the A versions, at 10.8 m (35 ft), due to a more powerful booster. The SA-2B could engage targets at altitudes between 500 and 30 km (1,600,000 and 98,000 ft) and ranges up to 34 km (21 mi).
  • SA-2C; S-75M Volkhov. Once again, the new model featured an upgraded radar, the Fan Song-C, mated to an improved V-750M missile. The improved -2B was deployed in 1961. The V-750M was externally identical to the V-750VK/V-750VN, but it had improved performance for range up to 43 km (27 mi) and reduced lower altitude limits of 400 m (1,300 ft).
  • SA-2D; Fan Song-E radar and V-750SM missiles. The V-750SM differed significantly from the A/B/C versions in having new antennas and a longer barometric nose probe. Several other differences were associated with the sustainer motor casing. The missile is 10.8 m (35 ft) long and has the same body diameters and warhead as the SA-2C, but the weight is increased to 2,450 kg (5,400 lb). The effective maximum range is 43 km (27 mi), the minimum range is 6 km (3.7 mi), and the intercept altitude envelope is between 250 and 25,000 m (820 and 82,000 ft). Improved aircraft counter measures led to the development of the Fan Song-E with its better antennas which could cut through heavy jamming.
  • SA-2E: Fan Song-E radar and V-750AK missiles. Similar rocket to the D model, but with a bulbous warhead section lacking the older missile's forward fins. The SA-2E is 11.2 m (37 ft) long, has a body diameter of 0.5 m (20 in), and weighs 2,450 kg (5,400 lb) at launch. The missile can be fitted with either a command-detonated 15 kt nuclear warhead or a 295 kg (650 lb) conventional HE warhead.
  • SA-2F: Fan Song-F radar and V-750SM missiles. After watching jamming in Vietnam and the Six-Day War render the SA-2 completely ineffective, the existing systems were quickly upgraded with a new radar system designed to help ignore wide-band scintillation jamming. The command system also included a home-on-jam mode to attack aircraft carrying strobe jammers, as well as a completely optical system (of limited use) when these failed. Fs were developed starting in 1968 and deployed in the USSR later that year, while shipments to Vietnam started in late 1970.
  • SA-2 FC: Latest Chinese version. It can track six targets simultaneously and is able to control 3 missiles simultaneously.
  • S-75M Volga (Russian С-75М Волга - Volga River). Version from 1995.

As previously mentioned, most nations with S-75s have matched parts from different versions or third-party missile systems, or they have added locally produced components. This has created a wide variety of S-75 systems which meet local needs.

  • HQ-1 (Hong Qi, Red Flag): Chinese version of SA-2 with additional ECCM electronics to counter the System-12 ECM aboard U-2s flown by the Republic of China Air Force Black Cat Squadron.
  • HQ-2: Upgraded HQ-1 with additional ECCM capability to counter the System-13 ECM aboard U-2s flown by Republic of China Air Force Black Cat Squadron. Upgraded HQ-2s remain in service today, and the latest version utilizes passive phased array radar designated SJ-202, which is able to simultaneously track and engage multiple targets at 115 km (71 mi) and 80 km (50 mi), respectively. The adoption of multifunction SJ-202 radar has eliminated the need to have multiple, single-function radars, and thus greatly improved the overall effectiveness of the HQ-2 air defense system. A target drone version is designated BA-6.

Isayev S-125 Neva/Pechora

The Isayev S-125 Neva/Pechora is Soviet surface-to-air missile system was designed to complement the S-25 and S-75. It has a shorter effective range and lower engagement altitude than either of its predecessors and also flies slower, but due to its two-stage design it is more effective against more maneuverable targets. It is also able to engage lower flying targets than the previous systems, and being more modern it is much more resistant to ECM than the S-75. The 5V24 (V-600) missiles reach around Mach 3 to 3.5 in flight, both stages powered by solid fuel rocket motors. The S-125, like the S-75, uses radio command guidance. The naval version of this system has the NATO reporting name SA-N-1 Goa and original designation M-1 Volna (Russian Волна – wave).

The S-125 is somewhat mobile, an improvement over the S-75 system. The missiles are typically deployed on fixed turrets containing two or four but can be carried ready-to-fire on ZIL trucks in pairs. Reloading the fixed launchers takes a few minutes.

Missile

The S-125 system uses 2 different missiles versions. The V-600 (or 5V24) had the smallest warhead with only 60 kg of High-Explosive. It had a range of about 15 km.

The later version is named V-601 (or 5V27). It has a length of 6.09 m, a wing span of 2.2 m and a body diameter of 0.375 m. This missile weighs 953 kg at launch, and has a 70 kg warhead containing 33 kg of HE and 4,500 fragments. The minimum range is 3.5 km, and the maximum is 35 km (with the Pechora 2A). The intercept altitudes are between 100 m and 18 km.

Radars

The launchers are accompanied by a command building or truck and three primary radar systems:

  • P-15 "Flat Face" or P-15M(2) "Squat Eye" 380 kW C-band target acquisition radar (also used by the SA-6 and SA-8, range 250 km/155 miles)
  • SNR-125 "Low Blow" 250 kW I/D-band tracking, fire control and guidance radar (range 40 km/25 miles, second mode 80 km/50 miles)
  • PRV-11 "Side Net" E-band height finder (also used by SA-2, SA-4 and SA-5, range 28 km/17 miles, max height 32 km/105,000 ft)

"Flat Face"/"Squat Eye" is mounted on a van ("Squat Eye" on a taller mast for better performance against low-altitude targets also an IFF [Identifies Friend or Foe]), "Low Blow" on a trailer and "Side Net" on a box-bodied trailer.

Isayev S-125 Variants and upgrades

Naval version

Work on a naval version M-1 Volna (SA-N-1) started in 1956, along with work on a land version. It was first mounted on a rebuilt Kotlin class destroyer (Project 56K) Bravyi and tested in 1962. In the same year, the system was accepted. The basic missile was a V-600 (or 4K90) (range: from 4 to 15 km, altitude: from 0.1 to 10 km). Fire control and guidance is carried out by 4R90 Yatagan radar, with five parabolic antennas on a common head. Only one target can be engaged at a time (or two, for ships fitted with two Volna systems). In case of emergency, Volna could be also used against naval targets, due to short response time.

The first launcher type was the two-missile ZIF-101, with a magazine for 16 missiles. In 1963 an improved two-missile launcher, ZIF-102, with a magazine for 32 missiles, was introduced to new ship classes. In 1967 Volna systems were upgraded to Volna-M (SA-N-1B) with V-601 (4K91) missiles (range: 4–22 km, altitude: 0.1–14 km).

In 1974 - 1976 some systems were modernized to Volna-P standard, with an additional TV target tracking channel and better resistance to jamming. Later, improved V-601M missiles were introduced, with lower minimal attack altitude against aerial targets (system Volna-N).

Some Indian frigates also carry the M-1 Volna system.

Modern upgrades

Since Russia replaced most of its S-125 sites with SA-10 and SA-12 systems, they decided to upgrade the S-125 systems being removed from service to make them more attractive to export customers. Released in 2000, the Pechora-2 version features better range, multiple target engagement ability and a higher probability of kill (PK). The launcher is moved onto a truck allowing much shorter relocation times. It is also possible to fire the Pechora-2M system against cruise missiles.

In 1999, a Russian-Belarusian financial-industrial consortium called Oboronitelnye Sistemy (Defense Systems) was awarded a contract to overhaul Egypt's S-125 SAM system. These refurbished weapons have been reintroduced as the S-125 Pechora 2M.

In 2001, Poland began offering an upgrade to the S-125 known as the Newa SC. This replaced many analogue components with digital ones for improved reliability and accuracy. This upgrade also involves mounting the missile launcher on a T-55 tank chassis (a TEL), greatly improving mobility and also adds IFF capability and data links. Radar is mounted on an 8-wheeled heavy truck chassis (formerly used for Scud launchers). Serbian modifications include terminal/camera homing from radar base.

Later the same year, the Russian version was upgraded again to the Pechora-M which upgraded almost all aspects of the system - the rocket motor, radar, guidance, warhead, fuse and electronics. There is an added laser/infra-red tracking device to allow launching of missiles without the use of the radar.

There is also a version of the S-125 available from Russia with the warhead replaced with telemetry instrumentation, for use as target drones.

In October, 2010, Ukrainian Aerotechnica announced a modernized version of S-125 named S-125-2D Pechora.

NPO Almaz S-200 Angara/Vega/Dubna

The NPO Almaz S-200 Angara/Vega/Dubna, 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.

Missiles

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). Maximum range is between 150 and 300 km (81 and 162 nmi), depending on the model. 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.

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.

Main radar system

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.

Additional radar systems

  • or "Big Back" E-band early warning radar (range 600 km\372 mi)
  • Kabina 66/5N87 "Back Net" or "Back Trap" E-band early warning radar (with special low-altitude search mod, range 370 km\230 mi, 3-6 RPM)
  • P-35/37 "Bar Lock\Bar Lock B" 1000 kW E\F-band target detection and tracking radar (with integrated IFF, range 392 km\242 mi, 7 RPM)
  • "Side Net" or "Odd Pair" E-band height finding radar (also used by the SA-2, 2K11 Krug and SA-6, range 240 km\148 mi, 3-6 RPM)
  • P-15M(2) "Squat Eye" 380 kW C-band target detection radar (range 128 km\80 mi)

9K32 Strela 2 Missile

The 9K32 “Strela-2” is a man-portable, shoulder-fired, low-altitude surface-to-air missile system with a high explosive warhead and passive infrared homing guidance. Broadly comparable to the US Army FIM-43 Redeye, it was the first generation of Soviet man portable SAMs, entering service in 1968, with series production starting in 1970.

Described by one expert as being "the premier Russian export line", the Strela and its variants have seen widespread use in nearly every regional conflict since 1968.

The missile launcher system consists of the green missile launch tube containing the missile, a grip stock and a cylindrical thermal battery. The launch tube is reloadable at depot, but missile rounds are delivered to fire units in their launch tubes. The device can be reloaded up to five times.

When engaging slow or straight-receding targets, the operator tracks the target with the iron sights in the launch tube and applies half-trigger. This action "uncages" the seeker and allows it attempt to track. If target IR signature can be tracked against the background present, this is indicated by green light and buzzer sound. The shooter then pulls the trigger fully, and immediately applies lead and superelevation. This method is called a manual engagement. An automatic mode, which is used against fast targets, allows the shooter to fully depress the trigger in one pull followed by immediate lead and superelevation of the launch tube. The seeker will uncage and will automatically launch the missile if a strong enough signal is detected.

Manufacturer lists reaction time measured from carrying position (missile carried at soldier's back with protective covers) to missile launch to be 13 seconds, a figure that is achievable but requires considerable training and skill in missile handling. With launcher on the shoulder, covers removed and sights extended, reaction time from fire command to launch reduces to 6–10 seconds, depending greatly on target difficulty and shooter's skill.

After activating the power supply to the missile electronics, the gunner waits for electricity supply and gyros to stabilize, puts the sights on target and tracks it smoothly with the launch tube's iron sights, and pulls the trigger on the grip stock. This activates the seeker electronics and the missile attempts to lock onto the target. If the target is producing a strong enough signal and the angular tracking rate is within acceptable launch parameters, the missile alerts the gunner that the target is locked on by illuminating a red light in the sight mechanism, and producing a constant buzzing noise. The operator then has 0.8 seconds to provide lead to the target while the missiles on-board power supply is activated and the throw-out motor ignited.

Should the target be outside acceptable parameters then the light cue in the sight and buzzer signal tell the gunner to re-aim the missile.

On launch, the booster burns out before the missile leaves the launch tube at 32 m/s, and rotating the missile at approximately 20 revolutions per second. As the missile leaves the tube the two forward steering fins unfold, as do the four rear stabilizing tail fins. The self-destruct mechanism is then armed, which is set to destroy the missile after between 14 and 17 seconds to prevent it hitting the ground if it should miss the target.

Once the missile is five and half meters away from the gunner, approximately 0.3 seconds after leaving the launch tube it activates the rocket sustainer motor. The sustainer motor takes it to a velocity of 430 meters per second, and sustains it at this speed. Once it reaches peak speed at a distance of around 120 meters from the gunner, the final safety mechanism is disabled and the missile is fully armed. All told, the booster burns for 0.5 second and the driving engine for another 2.0 seconds.

The missile's uncooled lead sulphide passive infra-red seeker head detects infrared radiation at below 2.8 μm in wavelength. It has a 1.9 degree field of view and can track at 9 degrees per second. The seeker head tracks the target with an amplitude-modulated spinning reticle (spin-scan or AM tracking), which attempts to keep the seeker constantly pointed towards the target. The spinning reticle measures the amount of incoming infrared (IR) energy. It does this by using a circular pattern that has solid portions and slats that allow the IR energy to pass through to the seeker. As the reticle spins IR energy passes through the open portions of the reticle. Based on where the IR energy falls on the reticle the amount or amplitude of IR energy allowed through to the seeker increases the closer to the center of the reticle. Therefore, the seeker is able to identify where the center of the IR energy is. If the seeker detects a decrease in the amplitude of the IR energy it steers the missile back towards where the IR energy was the strongest. Unfortunately, the seeker's design creates a dead-space in the middle of the reticle. The center mounted reticle has no detection capability. This means that as the seeker tracks a target as soon as the seeker is dead center, (aimed directly at the IR source) there is a decrease in the amplitude of IR energy. The seeker interprets this decrease as being off target so it changes direction. This causes the missile to move off target until another decrease in IR energy is detected and the process repeats itself. This gives the missile a very noticeable wobble in flight as the seeker bounces in and out from the dead-space. This wobble becomes more pronounced as the missile closes on the target as the IR energy fills a greater portion of the reticle. These continuous course corrections effectively bleed energy from the missile reducing its range and velocity.

The guidance of the SA-7 follows proportional convergence logic, also known as angle rate tracking system or pro-logic. In this method as the seeker tracks the target, the missile is turned towards where the seeker is turning towards - not where it is pointing at - relative to the missile longitudinal axis. Against a target flying in a straight-line course at constant speed, the angle rate of seeker-to-body reduces to zero when the missile is in a straight-line flight path to intercept point.

Type 91 Portable Surface to Air Missile

Type 91 surface-to-air missile is a Japanese man-portable surface-to-air missile. Its appearance is similar to the US-made FIM-92 Stinger anti-aircraft missile.

In the ranks of the JSDF, the Type 91 is known as Hand Arrow.

The Type 91 missile is similar to the Stinger missile it replaced, with two rocket solid motors, an initial booster motor and a sustainer. The seeker however is an advanced imaging seeker operating in both the visual and infra-red frequency ranges: 0.4 to 0.7 µm and 3.5 to 5.2 µm respectively. On launch, the missile records the target's image profile and is able to ignore defensive countermeasures such as flares.

Improvements of the Type 91 Kai included missile with image-infra-red seeker, smokeless motor and the capability to have faster shooting and target acquisition and was also improved for the ability to be used at night.

Umkhonto Missile

Umkhonto Missile is a South African, vertical launch (VLS) surface-to-air missile (SAM) manufactured by Denel Dynamics (formerly known as Kentron) available in infrared homing (Umkhonto-IR) and radar homing version (Umkhonto-R).

Umkhonto-IR Mk1

Designed for all-round defence against simultaneous air attacks from multiple targets, the Umkhonto-IR missile is the first vertically launched infrared-homing surface-to-air missile, also the first IR-homing missile to use lock-on-after-launch. Upon launch, the missile flies to a lock-on point, following on-board inertial navigation. The missile then activates its two-colour IR-seeker (variant of U-Darter AAM's seeker) and locks on. Target updates are received via data link, enabling the missile to counter evasive manoeuvres by the target.

The Umkhonto has a set of tail-mounted, aerodynamic control fins, as well as thrust vectoring vanes in the motor nozzle (similar to Denel's A-Darter AAM), allowing for 40 g manoeuvring. The system's 3-D fire-control radar enables simultaneous engagement of eight targets for the naval version. The missile uses a low-smoke propellant to avoid detection. In July 2005 it was successfully tested in various scenarios against Denel-made Skua drones.

Extended range versions (Umkhonto-ER) are in development. They will feature a rocket booster and IR or Radar seekers.

Umkhonto-IR Mk2

This variant of the IR Umkhonto was recently developed for the Finnish Navy. It has a more advanced seeker-head algorithms for differentiating between the target and background clutter often found in and around the Baltic archipelago. Because of the improvement in the seeker head, the newer version has a more efficient flight path allowing for an increase in range of 3km; a new maximum range of 15km.

Denel Dynamics has stated its intention to end production of the Mk1 and continue with Mk2 version of the missile, as a part of the missile's overall growth path.

Umkhonto-R

The radar-homing version's range is extended to 25 km (16 mi) and has a higher operational ceiling 12,000 m (39,000 ft). It is also 65 kg (140 lb) heavier and 98 cm (39 in) longer than the Umkhonto-IR version. Denel Dynamics is currently in negotiations with the Brazilian Navy for joint development of the missile.

PZR Grom Portable Air Defense Missile

The Grom Missile is a man-portable air-defense system produced in Poland. It consists of a 72 mm anti-aircraft missile set with a flight speed of 650 m/s, as well as a single-use launcher, re-usable gripstock and thermal battery coolant assembly electric unit. The full name of the system is PZR Grom, PZR standing for Przeciwlotniczy Zestaw Rakietowy (literally anti-air rocket-propelled system).

The Grom Missile is designed to target low-flying helicopters and aeroplanes. As such, the Grom missile is used by other surface-to-air defence systems of Polish design, including ZSU-23-4MP Biała, ZUR-23-2KG and POPRAD self-propelled artillery system. It should not to be confused with versions of the Zvezda Kh-23 air-to-surface missile built under licence in Yugoslavia/Serbia as the Grom-A and Grom-B.

The system is designed to be operated by one soldier. It consists of a single-stage projectile, a single-use tubular launcher, a starting mechanism, and an on-ground power supply. The rocket projectile uses solid propellant. The infrared aiming sensor is cooled with liquid nitrogen. There are options for identification friend or foe and thermovision.

RBS - Robotsystem 70 Anti Aircraft Missile

RBS 70 (Robotsystem 70) is a Swedish MANPADS designed for combat in all climate zones and with little to no support from other forces. It uses the RB 70 missile which is also in use in a number of other Swedish missile systems.

Robotsystem 70 Design

The RBS 70 is a short-range man-portable (MANPADS), laser guided missile system. The operator receives instructions on the position of the target from a local SLT (combat-control terminal) which is about the size of a laptop. The SLT in turn receives information through an encoded radio broadcast made by either a radar station (PS 90, PS 70) or some other information gathering source. When the target has been acquired by the operator he turns off the safety, which switches on the main laser and sends out an IFF signal and if positive makes firing impossible. If the operator is confident that he has a good track he fires. The missile then flies in the beam of the laser from the sight, adjusting its position constantly to stay within the beam. This puts a lot of pressure on the operator who needs to have a very steady aim. If the missile is guided to within 30 meters of the target a kill is 95% assured.

The exhaust is vented in the missile's midsection and the laser beam riding system is fitted in the tail, where it is extremely difficult to jam.

RBS 70 has been constantly updated and improved, the first versions (Mk 0) had a short range and limited kill capabilities but this was much improved in later versions. Mk 1 and Mk 2 followed shortly and are the standard RBS 70 with a range of 5,000–6,000 m and a ceiling of 3,000 m. RBS 70 is a product of Saab Bofors Dynamics and is operational in 15 customer countries, on all continents and in arctic, desert, and tropical environments.

Latest upgrade

The latest development is the BOLIDE system. The BOLIDE missile is an RBS 70 Mk 2 upgrade that is faster (Mach 2 vs Mach 1.6), with a range up to 8 km (4.8 miles) and can reach an altitude of 5 km. The BOLIDE has also a new warhead, which is a shaped charge with a pre-fragmented jacket, the adaptable proximity fuze gives it full effectiveness against a wider variety of targets, and new reprogrammable electronics gives it the possibility to engage attack cruise missiles and UAVs. Deliveries were initiated in 2005.
