Russian Ka-52K attack helicopter variant to receive AESA radar.

[Henry ME 95]

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.

180 km for a MMW radar is very impressive

So, the above radar is different from the one reported earlier?

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 Arbalet/Albalet is a millimetric-wave radar and also used on Mi-28A/N.

180-200km is usefull, given that the naval Ka-52K is capable of launching the 600+ kg, 100+km Kh-31 and 600+kg, 130km Kh-35 air-to-surface, anti-ship missiles (newest Kh-35V/UV/UVE is longer ranged and also for helicopter launch). As well as the 500+kg, 40km Kh-38/Kh-38M modular guided air-to-surface missile, which is meant to succeed the venerable Kh-25/AS-12 air-to-ground missile.

The Ka-52K itself carries the Arbalet-52 radar with parabolic antenna and mechanical scanning. But its developer KRET is now offering a more powerful AESA radar with detection ranges increased from 25 to 100 km to over 200 km (more than 100 nm), “so as to provide extended-range targeting capability for the air-launched missiles including the Kh-31 and Kh-35.”

While nice that the radar is also capable of detecting low-altitude aerial targets such as cruise missiles and unmanned aerial vehicles (UAVs) and of providing data to cue onboard electro-optical devices and corresponding weapons to these targets, the more important questions are whether the helicopter can relay any such radar data back to the LHD that serves as mother ship, and whether that ship can effectively handle such data and fuse it with other data into an integrated tactical picture. If so, the new radar could possibly provide the ship and its task force with a form of AEW/C.

It is suggested in past but not sure, esp. where interaction with mother ship is concerned.

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.

Great photo series here: http://bastion-karpenko.ru/ka-52k-mvms-2015/

The Ka-52K is a navalised version of the ground-based Ka-52 Alligator combat helicopter operated by the Russian Air Force.

The special "navalized" version of the helicotper will be specially equipped to conduct attack missions against targets at sea and on the ground which requires different sensors and armaments than those used on the basic Ka-52 helicopter.

The major difference will be the radar: A modified version of the Mig-35 fighter's Zhuk-A phased array radar is currently being developped to fit into the Ka-52K nose cone. This will be a major step forward compared to the base Ka-52 helicopter as the AESA radar Zhuk-A is among the most advanced radars to date in Russia. The radar is stated to provide a detection range of 130 km for a head on target with up to 30 targets tracked and 6 of those engaged at any one time.
