Ka-52 Alligator is an all-weather attack helicopter operated by the Russian Air Force. Developed by Kamov Design Bureau (part of Russian Helicopters), Ka-52 is a twin-seat variant of the Ka-50 attack helicopter.
The Ka-52 helicopter can destroy enemy armoured and unarmoured ground targets, low-speed aerial targets and personnel at the frontline and in tactical depth. It is also deployed as a surveillance platform and aerial command post for a group of attack helicopters.
Kamov Ka-50 Hokum: Here
The first Ka-52 helicopter was rolled out in December 1996. The helicopter completed its first flight in June 1997. The serial production of Ka-52 began in 2008 at Progress Arsenyev Aviation plant in the Primorye region of Russia.
Russia plans to equip its proposed Mistral Class amphibious assault ships with Ka-52K helicopters. Ka-52K is a naval variant of the Ka-52 Alligator.
Orders and deliveries of the Russian helicopter
In December 2010, the Russian Air Force’s 334th Tactical Deployment Centre in Torzhok received three Ka-52s. The twin-seat Ka-52 will serve in the air force as a special mission helicopter.
The Russian Air Force began fielding Ka-52 helicopters in April 2011. The Ka-52 will replace the Ka-50 Black Shark fleet that is in service with the Russian Air Force.
Ka-52 design, cockpit and avionics
The Ka-52 Alligator is a next-generation reconnaissance and combat helicopter designed to destroy tanks, armoured and non-armoured ground targets, and enemy troops and helicopters both on the front line and in tactical reserves. The helicopter can operate around the clock and in all weathers. The Ka-52 can provide target acquisition and designation for helicopter teams and ground troop command and control centres. It can also provide fire support for troop landings, fly routine patrols and escort military convoys.
- Ka-52 Alligator is fitted with signature control devices as well as electronic and active counter-measures. It meets the latest Russian and international standards for technical operation of military helicopters.
- The helicopter has a two-seat cockpit and can be flown by either pilot. Its advanced flight capabilities – achieved in part thanks to its coaxial rotors – make the helicopter highly manoeuvrable in limited space and thus able to adopt an advantageous attack position.
- The Ka-52 Alligator’s two VK-2500 turboshaft engines allow the helicopter to operate at altitudes above 5,000m. It has a static ceiling of 4,000m, and is able to take off and land in hot climates and in high mountainous terrain. The Alligator can also operate in cold climates and icy conditions.
- The Ka-52 Alligator is equipped with the latest avionics suite and powerful offensive weapons that can be configured for a wide range of combat missions.
- The Ka-52 Alligator offers a high degree of protection to its crew, advanced automated systems for ease of piloting, and is easy to service and maintain on the ground
Ka-52 incorporates a slightly modified design of the Ka-50 helicopter. The helicopter features a wider nose and an extended fuselage due to its twin-seat cockpit. The commonality of the airframe, components and systems of the two variants is about 85%.
The helicopter has a length of 16m, height of 4.9m and main rotor diameter of 14.5m. The maximum take-off weight of the Ka-52 is 10,800kg.
Russia’s Alligator attack helicopter’s land version to get folding blades
The land version of the Kamov Ka-52 Alligator (NATO reporting name: Hokum-B) reconnaissance/attack helicopter is expected to get folding blades as part of its upgrade, Russian Helicopters Group, part of Russia’s state hi-tech corporation Rostec, told TASS on Monday.
“As the technique of folding blades has been mastered, a possibility is being considered to use this technology also in the manufacture of the land version of this helicopter’s modification,” the Russian Helicopters press office said.
The helicopter’s modernization has already begun. This innovation will make it possible to keep this helicopter at hangars, which gives the Alligator’s land version a fundamental advantage, the press office said.
Russian Deputy Defense Minister Yuri Borisov earlier said that Ka-52 Alligator helicopters could be modernized considering the experience of their combat use in Syria.
According to the deputy defense minister, the Ka-52 has proved its worth in combat operations in Syria. Source tass.com
The twin-seat cockpit accommodates two crew members in side-by-side arrangement. Both the crew members are seated on identical K-37-800M ejection seats.
K-37-800M ejection seats
CAS K-37-800M consists of two parts – an armchair and a side part, designed to perform the functions of the pilot’s seat of the Ka-50 and Ka-52 helicopter and providing in combination with the ZSh-7VS helmet and oxygen equipment of the KCO-VK-LP safe emergency exit by bailout with the help of a towing rocket engine at an indicated flight speed from 90 to 350 km / h in the altitude range from 0 to 5000 m and reducing the loads acting on the pilot during an emergency landing using the energy-absorbing cushioning suspension of the chair.
For two-seat aircraft, it is possible to dilute the trajectories of pilots and their parachutes with simultaneous bailouts.
CAS is available in several versions.
CAS is combined:
- with flight clothing (summer, demi-season and winter);
- with on-board oxygen equipment KCO-VK-LP;
- with a protective helmet ZSh-7VS (ZSh-7V), including with the ONV;
- with NAZ-Ir;
- with the marine rescue kit MSK-5;
- with the air rescue belt ASP-74;
- with the apparatus of underwater breathing APD from the kit of rescue equipment KSS.
Main technical characteristics:
- The range of bailout rates from 90 to 350 km / h
- Range of bailout heights from 0 to 5000 m
- The total weight of the pilot’s equipment is from 6.5 to 12.8 kg.
- Allowed pilot parameters from 57.0 to 91.4 kg; growth sitting from 810 mm to 980 mm.
- The weight of the seat of the system with pyrocharges is not more than 57.25 kg.
Year of development: 2007
From the book of A. Mazepov, A. Mihkaev, V. Zenkin, A Zhirnov and A. Fomin about the Ka-50 called Polygon from 1996, on Page 31, there is said how the Armor was made on Ka-50 and after that also installed on Mi-28.
It is a 3 hardlinered armor, the inner cockpit section made of a full single titanium alloy “bathtub” covering both pilots, followed by a middle liner of ceramic plates, which caused trouble first after a single shot they break apart and lost all its protective abilities, they avoided that by covering this ceramic plates with kevlar/aramid that was glued on tightend and the outer liner which gives the aerodynamic shape and is made of alluminium alloy with a part carbon in it. The total armor per pilot for russian Ka-50 which they could use was about 300kg while the Apache uses about 90kg of armor per pilot. The Mi-28 has about 250-280kg which was mentioned somewhere else. The Ka-52 has less armor than both Mi-28 and Ka-50 spend for each pilot but it is still in the figure of 150-200kg. Source: Russian Defense
The modern glass cockpit is equipped with a head-up-display (HUD), four SMD 66 multifunction displays, helmet-mounted sight display, image intensifiers and a GPS receiver. The helicopter also integrates a FAZOTRON cabin desk radio-locator and navigation and attack system for helicopters (NASH).
Helmet-mounted sight display
In September 2012 Russian Helicopters, a subsidiary of Oboronprom, signed a long-term contract with Ramenskoye Design Company (RDC) for deliveries of avionics equipment. As part of the contract, RDC is responsible for the supply of avionics packages for Ka-52 attack helicopter and Ka-52K advanced ship-based variant between 2013 and 2020.
Ka-52K helicopter design and features
The new ship-borne Ka-52K is based on the airframe of the Ka-52 Alligator, which itself is a modified variant of the Ka-50 attack helicopter. The fuselage is covered with resilient anti-corrosion coating and is fitted with folding blades and wings.
The equipment and systems of the helicopter have been modified to suit naval operations.
The rotor system is equipped with elastomeric bearings in blade-mast joints for higher take-off weights. The helicopter complies with the latest Russian and international standards for technical operation of military helicopters.
The helicopter features an advanced glass cockpit, which accommodates two pilots in side-by-side layout. It can be operated by either pilot and is equipped with advanced avionics and powerful weapon systems, which can be configured for different roles.
The onboard avionics with the use of radio equipment and satellite navigation ensure autonomous landing on the ship deck, and the onboard equipment further makes the helicopter a network-centric system for interaction between the Navy and Air Force.
The helicopter is also integrated with an air-conditioning system for conducting missions in the humid marine atmosphere.
Ka-52K sensors / radars
The Ka-52K is equipped with a laser-beam guidance system and Okhotnik video processing system developed by KRET.
Okhotnik provides the helicopter with increased range of detection and identification, while the auto-tracking stabilises the video field on the target and transmits a digital error code in case of a mismatch between the display coordinates and the line of sight.
The onboard Arbalet radar system allows the helicopter to effectively perform combat missions even in environments exposed to electronic jamming. The helicopter can detect hostile vessels at a range of 200km.
The ship-based helicopter is equipped with Vitebsk defence system, SAU-800 automatic control system and GOES-451 gyro-stabilised optronic station.
The SAU-800 enables the pilots to operate the helicopter in manual, automated, and automatic control modes. It is integrated with the SIVPV-52 data recording and processing system developed by Radioelectronic Technologies.
Ka-52K attack helicopter poised for AESA radar upgrade
The navalised variant of the the Kamov Ka-52 Alligator (Hokum-B) attack/reconnaissance helicopter – the Ka-52K Katran – will be equipped with a compact active electronically scanned array (AESA) radar from Russian defense contractor Radio-Electronic Technologies (KRET), a company spokesperson told IHS Jane’s .
KRET claims that its AESA radar will be able to operate in the millimetric wavelength for effective ground target acquisition as well as the centimetric spectrum to enable large naval targets to be detected at a range of 180 km.
The radar is also capable of detecting low-altitude aerial targets such as cruise missiles and unmanned aerial vehicles (UAVs), providing data to cue onboard electro-optical devices and corresponding weapons to these targets.
Flight safety is enhanced with ground moving target indication and tracking modes, which assists the crew in coping with low visibility conditions such as fog, dust and night-time operations. The radar also detects ground obstacles including transmission towers and power lines.
The Ka-52K helicopter – developed to sink amphibious landing ships as well as the transports of enemy strike groups and convoys with its ability to employ anti-ship cruise missiles such as the high-speed Kh-31AD – was originally slated for deployment aboard the two French-built Mistral-class amphibious command ships originally destined for the Russian Navy.
However, delivery of the ships to Russia had subsequently been cancelled by France due to the former’s annexation of Crimea.
There are now plans to add the helicopters already constructed to the air wing of the Project 11435 Admiral Kuznetsov aircraft carrier. Posted on 08 August 2016 janes.com

The gun has a maximum rate of fire of 550 rounds a minute and can engage light armoured targets within the range of 1,500m, soft-skinned targets and infantry at ranges up to 4,000m, and air targets flying at low altitudes.
The Ka-52K is also capable of launching Kh-31 and Kh-35 air-to-surface missiles, similar to carrier-based MiG-29K/KUB multipurpose fighter jets and Sukhoi Su-33 (Flanker-C) aircraft. source naval-technology.com
Kh-31 air-to-surface missiles
The Kh-31A high-speed anti-ship airborne missile is designed to engage warships of different type, including destroyers, navigating both autonomously and within naval attack groupings.
The Kh-31A missile can be effeciently launched either independently or in salvo, in fair and adverse weather, clutter and active jamming conditions, against preplanned targets and targets of opportunity.
The missile is equipped with a high-precision active radar homing head and a radio-altimeter. The active radar homing head can operate in the pre-launch and en route (post-decent) target designation modes. It ensures target acquisition and selection, determination of target coordinates (range, azimuth, elevation), generation of command signals and their feeding into the missile’s guidance system.
Thanks to its relatively small weight and size the Kh-31A missile can be employed from various air combat platforms, including moderately sized ones. The missile has passed state acceptance tests on a number of series-production front-line combat aircraft of the Russian Air Force. It makes part of weapon systems of modern combat aircraft, such as the Su-25, Su-27, Su-30, Su-34, MiG-29, etc., and can be adapted to other types of Russian or foreign-origin aircraft during their modernization.
The Kh-31A missile is suspended under the carrier aircraft with necessary links to its onboard systems, carried in flight and launched (or jettisoned in emergency, if required) by means of the AKU-58A missile ejection unit.

The hardpoints can carry VIKHR anti-tank guided missiles (ATGM), ATAKA missiles with laser guidance system and B8V-20 rocket launchers for 80mm unguided S-8 rockets. VIKHR anti-tank missile has a range of eight to ten kilometres. The Ka-52s can also be armed with IGLA-V anti-aircraft guided missiles.
VIKHR anti-tank guided missiles (ATGM)
The 9A4172 Vikhr is a Russian long-range anti-tank guided missile. It is known in the West as the AT-16 or Scallion. It was developed in the Soviet Union during the 1980s. At the time Soviets needed a new missiles, to replace the 9K114 Shturm (Western reporting name AT-6 or Spiral) system, that could penetrate contemporary Western main battle tanks with composite and explosive reactive armor, such as the American M1 Abrams, German Leopard 2, and British Challenger. Prototypes were tested by the Soviet armed forces in 1989. First production missiles were delivered in 1992. During the same year the Vikhr was first publicly revealed. Since its introduction sales of the Vikhr missile have been slow, partly because Russia also uses Ataka missile, developed by another manufacturer, which is similar in function, but uses different guidance. In 2013 Russian MoD ordered over 6 000 Vikhr-1 missiles in order to prevent the manufacturer from going bankrupt. Delivery of these missiles commenced in 2015 and was completed in 2016. The Vikhr has been exported to Egypt, and possibly some countries. Source military-today.com
ATAKA missiles with laser guidance system
The Ataka (Attack) (Western reporting name AT-9 Spiral-2) is a long-range anti-tank guided missile system. It was developed in the 1980s in the Soviet Union as a follow-on to the previous Shturm (AT-6 Spiral) system, that was introduced in 1976. Soviets needed a new missiles, that could defeat contemporary Western main battle tanks with composite and explosive reactive armor, such as the American M1 Abrams, German Leopard 2, and British Challenger. Launchers with Ataka missiles can be mounted on helicopters, vehicles and watercraft. It is basically similar to the previous Shturm, but has longer range and is more resistant to electronic countermeasures. The Ataka missiles are currently used by the Russian armed forces. These missiles have been exported to Algeria, Brazil, India, Kazakhstan, and Slovenia. Some sources report that these missiles have also been exported to Iran and North Korea.
The Ataka can be fired from existing Shturm launch platforms, such as a Shturm-S anti-tank missile carrier, without any modifications. It is used on attack helicopters, such as the Mi-24, Mi-28, and Ka-52, though it can be also carried by transport helicopters. Source military-today.com
IGLA-V anti-aircraft guided missiles
The 9K38 Igla (Needle) is a Man-Portable Air Defense System (MANPADS) developed by Soviet Union in the 1970s. It succeeded the older Strela-3 with better range and seeker sensitivity. The system uses an 9M39 Surface-to-Air missile (SAM). It was adopted by the Soviet Army in 1981. This air defense system is known in the West as SA-18 Grouse. The Igla MANPADS can engage aircraft, helicopters and UAVs.
Comparing with the Strela series, the Igla has increased warhead weight. Its infrared guidance system uses proportional convergence logic for target acquisition and movement prediction.
The 9M39 missile constitutes a seeker head, control system and propulsion system. The 9E410 seeking head contains photo resistor sensor made of Indium cooled down to -200 degree Celsius for better IR source acquisition. The seeker head also contains logical selection unit to enhance system’s acquisition capability during target engagement. The Igla also uses 9S520 night fire equipment package.

Hermes-A extreme-range anti-tank guided missile (ATGM) system
The products are able to hit targets at a distance of up to 30 km, while the most effective helicopter ATGMs – Attack, Vortex and Hellfire – do not exceed 10 km. According to experts, the use of “Hermes” in Syria will not only test the unique missile system in battle, but also demonstrate the novelty to potential buyers, especially Egypt.
Development and testing of the newest ATGM the Tula Design Bureau of Instrument Engineering has been conducting since the mid-1990s. Despite the fact that “Hermes” is officially called an anti-tank missile, it is a universal product capable of hitting a wide range of targets, including structures, field fortifications and the enemy’s living force.
As the editor-in-chief of the Internet project Militaryrussia Dmitry Kornev told Izvestia, the latest Hermes missile is equipped with a combined guidance system capable of detecting enemy targets even in the most difficult weather conditions.
– On the “Hermes” is a combined homing head (GOS) with an infrared sensor and a laser guidance channel, “says Kornev. – The purpose of the rocket can be “illuminated” from the ground. That is, an air racer, a helicopter or an airplane will aim the laser beam at the target, and the GOS “Hermes” will “see” the laser spot and take the target. But if the laser does not have a backlight, then infrared sensors come into effect, which will detect enemy targets for the heat generated. In the future, miniature radar stations can appear on the Hermes missiles, which, combined with infrared guidance, will ensure the unique accuracy of the latest products.
According to the expert, the speed of the Russian guided missile is close to hypersonic.
“The two-stage design of Hermes is largely unified with the design of the anti-aircraft missile of the Pantsir-S complex,” says Kornev. – The starting stage disperses the missile and leads to the target area, after which it is separated from the product. Then the battle bloc enters the case, which is already searching for the target, and then destroys it. The minus of this layout is the large weight of the rocket. According to available data, the product weighs more than 90 kg, while the “Vortex” ATGM is twice as light. Source vpk.name

Pastel entered development in 1982, possibly as a reaction to poor performance of Soviet fighters in the Middle East. By 1983 the initial design was produced. It was intended for the Mi-28, MiG-29K/M, Su-27M and others.
Pastel is a family of new generation digital RWRs.
Scans from 1.2-18GHz threat frequencies.
Accuracy is 3-5° with pinpoint location antenna, 10° in rough location antenna. 128 reprogrammable radar types. Detection range minimum of 120% of the radar’s range. 3 modes- operational target, programmed target, most dangerous target.
Detects and finds direction for pulse, pulse-doppler and CW mode radars in search, track and illumination modes. Classifies multiple threats by danger, with full display of all information about most threatening radar presented to crew. Controls EW systems, has the ability to control and assign targets to 6 anti-radiation missiles such as the Kh-31. Aural warnings for high threat situations.
Pastel may be made available for upgrade packages or built into new export models of the Mig-29 and Su-27 families. Source aerospace.boopidoo.com
