Ka-52 design, cockpit and avionics
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.
Modern glass cockpit is equipped with a head-up-display (HUD), four SMD 66 multifunction displays.Igor Djadan
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

IGLA-V anti-aircraft guided missiles
The 9K38 Igla 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 9M39 Surface-to-Air missile (SAM). It was adopted 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.
Igla-V is an air-to-air version, used on helicopters.
Igla-S, sometimes referred as Igla-Super. It is an improved variant in the Igla, which entered service with Russian Army in 2004. It is known in the West as SA-24 Grinch. It is more efficient weapon with longer range (up to 6 km). The missile was fitted with a new two-channel optical seeker with logic unit. It has higher jamming immunity due to good target selectivity against the background interference. The Igla-S also has increased warhead weight, laser based contact/proximity fuse, algorithm based optimal moment of explosion and high accuracy; all adds to the advantages of the new Igla-S over its predecessor. The warhead also features increased high explosive charge and fragment number. The warhead is made of Indium antimonide which allows lock onto receding target easier. The Igla-S has the same weight and size as the older missile, as well as similar launching/maintenance procedures. With its high combat effectiveness, Igla-S system can be used to engage cruise missiles and drones. This MANPADS has been exported to Armenia, Azerbaijan, Brazil, Libya, Slovenia, Thailand, Venezuela, Vietnam, and possibly some other countries.
Verba is the latest version. It was developed as a replacement for the Igla and Igla-S systems. The main improvement is a three-channel optical seeker. It uses three sensors, including ultraviolet, near infrared and mid-infrared. It improved discrimination abilities between real targets and decoys. This air defense system was approved for production in 2011. The Verba was adopted by the Russian Armed Forces in 2014. It has a 1.5 kg warhead and can reach targets at a range of 6 km and maximum altitude of 4.5 km.
Hwasung-Chong is a North Korean version of the Igla.
Grom is a Polish version of the Igla. In the early 1990s Polish intelligence services acquired design plans of the Igla missile. This missile entered service with the Polish armed forces in 1995.

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.

Ka-52K “Katran”: combat helicopters taking off from the deck of “Kuznetsov”- Video
Ka-52K Kaiman (NATO reporting name: Hokum-B) marinized attack-reconnaissance helicopter
The main difference in the naval variant from the basic Ka-52 Alligator attack helicopter is the folding main rotor blades and folding half-wings. The new version will also be adapted for naval use by increased corrosion protection and an adjusted air conditioning system. Ka-52K will receive a special avionics suite to enable instrument landing on the ship’s deck. The crew life support system will be upgraded to allow the pilots to work in immersion suits. Source aviationweek.com
The latest Russian combat helicopter Ka-52K Katran, developed to be operated from Mistral helicopter carriers, is able to detect and identify targets at a distance 1,5 times longer compared to Ka-52 Alligator thanks to Okhotnik video image processing system, RIA Novosti reports with reference to Radio electronic Technologies Concern (KRET, part of Rostec State Corporation) First Deputy CEO, Igor Nasenkov.
“Okhotnik video image processing system allows detecting and identifying targets at a distance 1,2 – 1,5 times longer as well as increasing operating time of a TV-channel within 24 hours. Automatic tracking allows stabilizing association of video channels’ field of view with a desired area and reporting mismatch of a target against the line of sight in the form of error codes sent to the tele-orientation system,” Nasenkov said.
KRET manufactures a number of systems for Ka-52K helicopter. In particular, it is fitted with highly efficient Vitebsk electronic warfare suite, GOES-451 gyro-stabilized electro-optical station, Arbalet radar station, laser guidance system, and SAU-800 automatic control system.
«The SAU-800 automatic control system allows piloting the helicopter in manual, automated and automatic modes. The SAU-800 is integrated with the SIVPV-52 aerometric data recording and processing system allowing a pilot to focus on usage of weapons,» Nasenkov said.
He noted that thanks to KRET Ka-52K is able to “carry out missions under any weather and lighting conditions. This vehicle is able to do much more than just provide support to assault forces”.
The Ka-52K may get anti-ship weapons in the future, but it will initially carry the same weapons as the baseline variant. The standard weapons set includes one 30-mm 2A42 integrated automatic cannon, S-8 unguided rockets, Vikhr (AT-12) laser-guided or Ataka-V radio-guided antitank missiles or underwing Strelets launchers with Igla surface-to-air missiles. The new radar would enable the Ka- 52K to use Kh-31 (AS-17 Krypton) and Kh-35 (AS-20 Kayak) anti-ship missiles. (ato.ru)
“For example, thanks to the radar developed by KRET, this helicopter is able to detect enemy ships at a distance of 200 km and destroy them using X-31 and X-35 anti-ship missiles. This fact makes the helicopter closer to Su-33 and MiG-29K carrier-based fighters in terms of combat capabilities,” the source noted.
Radioelectronic Technologies Concern (KRET) is the Russia’s largest holding company in the radio electronics industry; it was established in 2009 and it is a part of Rostec State Corporation. Its major areas of activities are: development and production of avionics suites for civil and military aircraft, radars, friend-or-foe identification systems, EW suites, measuring equipment, electric connectors, cable assemblies, etc. Source ruaviation.com
