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 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

Cockpit armor

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.

Ka-52K – RussianDefence.com

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.

Ka-52K – RussianDefence.com

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

MF2 Radar? – vitalykuzmin.net

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

Ka-52K weapon systems

The helicopter carries a 2A42-1 30mm automatic cannon and high-fragmentation, explosive incendiary, or armour-piercing rounds.

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.

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)

VIKHR anti-tank guided missiles (ATGM) – RUSSIA BEYOND

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

ATAKA missiles with laser guidance system (right)  – RUSSIA BEYOND

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. Source military-today.com

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

Desert Chameleon Armored personnel carrier – Kuwait Ministry of Internal Affairs

The Desert Chameleon was developed by Advanced Defense Vehicle Systems (ADVS) company. Previously this company was known as the General Purpose Vehicles (GPV). It developed a number of APCs, such as the GPV Captain and FNSS Pars with active suspension systems. Development of the Desert Chameleon started in 2007 to meet Kuwaiti requirement. Kuwait ordered some of these armored personnel carriers for Ministry of Internal Affairs. First production vehicles were delivered in 2010. Currently Kuwait is the only operator of this armored vehicle.


The Desert Chameleon is available in 4×4, 6×6, 8×8 and 10×10 configurations. It is claimed that 90% of the parts are interchangeable. This APC has a number of innovative features.

The Desert Chameleon has a welded steel armor hull. All-round protection is against 7.62-mm armor-piercing rounds. Add-on armor kit can be fitted for all-round protection against 14.5-mm armor-piercing rounds. Kuwaiti vehicles have this level of protection. This armored personnel carrier has a V-shaped hull for improved protection against mines and IED blasts.


The Desert Chameleon can be fitted with remotely controlled turret, armed with 30-mm Bushmaster cannon. There is also a coaxial 7.62-mm machine gun. This turret is designed to carry up to 40-mm caliber cannons. The turret is also fitted with a multi-sensor ball.


The 6×6 version accommodates crew of three and 7 fully-equipped troops. Troops enter and leave the vehicle via a large rear ramp, two side doors. In case of emergency troops exit the vehicle via roof hatches. There are some unusual firing ports provided for the troops. These can accommodate various weapons, but protection can not be compromised from the outside.


The Desert Chameleon is powered by a Caterpillar turbocharged diesel engine, developing 600 hp. Engine is coupled with Caterpillar automatic 6-speed transmission. Both engine and transmission are commercially available. There is also an auxiliary power unit, which can export power. This armored vehicle has selective all-wheel drive and selective all-wheel steering. The Desert Chameleon has an active suspension system with variable ride height. Such suspension smooths out the ride regardless of terrain. Vehicle can also lean in any direction which comes handy on on grades and slopes. Active suspension improves weapon control and improves crew comfort on extended operations.

The Desert Chameleon’s core design has amphibious capabilities. It can cross rivers and lakes. However this APC is not suitable for operation at sea.

Piranha V

The Piranha V is the latest and most protected vehicle of the Piranha line. It is a further development of the previous Piranha IV. The new armored vehicle was revealed in 2010. It is no longer considered as an armored personnel carrier but rather a wheeled infantry fighting vehicle. Two of these armored vehicles are in service with Monaco.


The Piranha V is better protected than its predecessors. It has an all-welded steel armor hull with integrated add-on composite modular armor. Protection can be upgraded to meet future threats. The baseline version provides all-round protection against 14.5-mm armor-piercing rounds and artillery shell splinters. Also there is growth potential for armor protection. Maximum armor level provides all-round protection against 25-mm armor-piercing projectiles. Vehicle has a double floor with a V-shaped hull and is well protected against landmines and IED blasts. It withstands a 10 kg anti-tank mine blast under any wheel. All occupants are seated on mine-protected seats. This IFV has an NBC protection system. The Piranha V is also proposed with LEDS-150 active protection system.


The baseline Piranha V has a payload capacity of 13 t. This multi-role vehicle can mount turrets fitted with various weapons, ranging from small caliber to up to 120-mm guns. Vehicle revealed in 2010 was fitted with a turret-mounted 30-mm chain gun. Secondary armament consists of remotely controlled weapon station, armed with a 12.7-mm machine gun.

The Piranha V has a crew of 2-3 and accommodates 8-9 troops, depending on the mission variant. Troops enter and leave the vehicle via rear ramp or roof hatches.


This infantry fighting vehicle is powered by a German MTU 6V199 TE21 turbocharged diesel engine, developing 580 hp. Engine is mated to a ZF 7-speed automatic transmission.

Series 199

Highly compact, with an output of 430-600 kW (585-816 hp) and adapted especially to the demands placed on military vehicles (with a dry sump lubrication system, for example). The Series 199 is available in 6V and 8V configurations and is an ideal drive system for tracked armored and heavy wheeled vehicles. Source mtu-online.com


The Piranha V has a full-time all-wheel drive. Vehicle uses height-adjustable semi-active hydropneumatic suspension and has improved off-road mobility. Vehicle has a four-axle steering. It is fitted with a central tyre inflation system. This IFV is not amphibious, however a specialized amphibious version might be developed in the future. The Piranha V can be airlifted by the Airbus A400M without preparation.

Airbus A400M: Details

Variants of this IFV might include armored personnel carrier, armored ambulance, command vehicle, reconnaissance vehicle, mortar carrier and fire support vehicle. A proposed desert version of this armored vehicle, known as Desert Piranha, is optimized for operation in hot climate conditions.


“Spain’s Ministry of Defence (MoD) has chosen the General Dynamics’ Piranha 5 as the base platform for its new 8×8 wheeled infantry fighting vehicle (IFV) prototype, industry sources have told IHS Jane’s .

While no decision has yet been openly announced by the MoD, the Spanish Army is looking to acquire at least 300 of the vehicles in an initial order expected to be worth about EUR1.5 billion (USD1.7 billion).

The Piranha 5 model, which is also being acquired by Denmark, was one of five solutions presented to the MoD earlier this year following a request for information (RfI), three of which were then assessed further.” – IHS Jane’s Defence Weekly

The mission management system (MMS) installed aboard the Saab 340 incorporates remote sensors and mission system components into a single user-friendly framework. It provides the aircraft with real-time display of sensor information, display of electronic charts, automated scene analysis and in-flight and ground processing.

The MMS also offers mission planning, immediate post-overpass analysis, support for remote sensors, classification of marine pollution, automated scene analysis, computer-aided report creation, geo-referencing and GIS capability, redundant storage and aircraft information system (AIS) support.


The aircraft is equipped with a retractable multiple StarSaphire HD EO/IR sensor. The Telephonics 1700B maritime surveillance radar onboard provides 360° coverage for multiple target identification, detection and tracking during over-water surveillance. The advanced sensors allow the aircraft to detect, classify and identify maritime surface contacts.


The Saab R4 airborne automatic identification system (AIS) transponder offers improved situational awareness to the operator during surveillance and SAR. The aircraft can be optionally fitted with a side-looking airborne radar (SLAR) and UV/IR line scanner for environmental monitoring.

A wireless broadband system with Internet connections is fitted in the crew rest area table in order to transmit information securely through wireless systems. The VHF/UHF tactical radio communication system facilitates a complete multi-band solution for law enforcement, military, medical, marine, SAR and public-service frequencies.

2 x CT7-9 turboprop engine

The turboprop engine used by the 340 is highly efficient engine with high range for its size. The engine can fly a maximum 470nm with a maximum total weight in excess of 29000lb (take off) on under 6000lb of fuel. The two engines can thrust the SAAB 340B and B Plus at 283 knots at an altitude of 25000 feet. Further information on range and payload is in figure 9 of the appendix.

The SAAB 340 has used different engines over the years, originally running CT7-5A2 turboprops the change to a CT7-9B led to an increase in the SHP of the engines, more power, and an increase in fuel efficiency. Source ukessays.com
