The Katran differs from the standard Alligator by the folding mechanism of the blades and carrying consoles. This makes the helicopter more compact, not only for basing on the ship's deck or in the hold, but also for transporting cargo aircraft. In addition, the machine is equipped with reinforced landing gear, which is not easy to break, even when hitting the ground. This solution allows to increase the survival rate of the crew during an emergency landing or when approaching the deck in a storm.
Throughout the seas of the temperate zone: from the coast of California and Chile to Kamchatka and Australia, and from Argentina and Florida to South Africa and the White Sea, the spotted prickly shark, or quatran (scientific name: Squalus acanthias) is widespread. In many countries, the katran is also known as the sea dog. In the Russian North, this predator is called a buttress, or a marigold. The katran shark belongs to the family, which, by the name of its most famous representative, is called the katraan shark.
Akua katran does not attack people. However, if an annoying diver grabs the predator by the tail, then the shark will respond adequately and bite the offender. All prickly sharks (there are 26 species of them) have two dorsal fins, in front of which sharp spikes are located. The anal fin in the family members is absent.
Spikes of a katran represent quite serious danger to the careless fisherman or the diver. The spikes are covered with poisonous mucus and as a result of the injection the victim may develop a strong tumor. The katran received its Russian name just due to these thorns. If “prickly shark” is a translation of a scientific Latin term (although the sea dog is also called in many other countries), then katran is a word of Greek origin. In the Black Sea, from the ancient "Homeric" times, there existed colonies of the ancient Greeks, who were famous sailors and skilled fishermen. In Greek, one of the names of this shark is kedroni, from the word "kedron", which means "sharp cone" or "sting". By the way, the name of the tree cedar - from here. Sea dogs justify their nickname by nibbling tackles, eating fish caught on hooks of tiers or seines, sometimes breaking nets.
Holding "Russian Helicopters" developing naval version of the Ka-52 - Ka-52K, the Russian Defense Ministry is interested in the success of this development work. This was announced on 23 March 2015 by Deputy Defense Minister Yuri Borisov. "First, have built their amphibious ships and a helicopter, the Ka-52K will be claimed by the ships of our surface fleet. So to bind the development work on the helicopter with the delivery or non-delivery" Mistral "would be wrong" - said Borisov, answering the question, whether the ship will find Ka-52K application in the Russian Navy, if the French helicopter will not be delivered.
According to him, the Ka-52K is a much needed helicopter. "And we are going to look for deadlines development activities," - said the deputy minister. He noted that the operating conditions of the sea helicopters differ significantly from the ground, so it took further improvements in terms of materials and components.
The naval version of the famous Kamov "drummer" is much better suited for the harsh naval everyday life than its front-line "colleagues" from the Air and Space Forces. A whole set of original technical solutions, many of which have no analogues abroad and are revolutionary in some way, have been used for "retaining the helicopter". Nonetheless, Katran has a rather difficult fate - the fleet does not yet have specialized ships for it.
Russia's Kamov Ka-52K (Hokum B) helicopters developed for use on the French-made Mistral-class helicopter carriers will be put to work in the Russian Navy, despite a failure by Paris to honor the contract, the general designer of "Ka" helicopters said 25 May 2015. "This circumstance [contract on Mistral ships delivery] wittingly or unwittingly led to the fact that the Russian Navy obtained another special purpose helicopter, which will find its remarkable place," Sergei Mikheev told RIA Novosti. Mikheev added that the Navy did not mind re-purposing the helicopters, as they can be used on any Russian Navy vessel.
Russia struck a deal with Egypt to deliver 46 Kamov Ka-52K navalized attack helicopters, the director-general of the state-run Russian Helicopters aircraft maker said on 30 December 2015. Ka-52Ks were designed for French-made Mistral helicopter carriers that were to join the Russian Navy, before France cancelled the deal over Ukraine. The warships are now being bought by Cairo.
The Ka-52K multi-purpose shipborne helicopter, put into service by 2017, is already partially equipped with tomorrow’s electronic equipment. Tomorrow for the helicopter, and not for fighter aircraft. It is equipped with a radar with an active phased antenna array “Zhuk-AE”, which allows detecting airborne targets at a distance of up to 300 km, and ground targets up to 70 km. For other helicopters such ranges are inaccessible.
The fuselage of the helicopter is treated with a special anti-corrosion agent, which in the conditions of sea humidity and salt saves the car from rust and prolongs its service life. The Ka-52K combat field made its own adjustments and in its “stuffing” - an upgraded air conditioning system was installed on the “Katrans”, to which you can connect the crew’s dense sea rescue suits. Without additional ventilation in such clothes it is too hot.
At the same time, the Qatran outperforms the Alligator in combat capabilities. The Ka-52K is equipped with a radio navigation system of near navigation, which was not used on the base model. Above the ocean, it is far from always possible to find a landmark, and building a route by the stars will only happen on a cloudless night. With the new system "Katranu" is much more difficult to "get lost". To detect targets, the Ka-52K is equipped with a powerful radar with an active phased array "Zhuk-A" - exactly the same that is put on the latest modifications of the Su-27 fighters and on the promising MiG-35. He is able to detect a tank, a plane or an enemy ship at ranges of up to 200 kilometers, and also accompany up to 30 targets and simultaneously fire up to eight.
The main armament of the Katran is expected to be the latest Hermes-A anti-tank guided missiles. In terms of their range (20 kilometers), they significantly exceed the Whirlwind (10 kilometers) and Ataku (six kilometers), which are armed with Ka-52 and Mi-28N, respectively. Thus, the helicopter does not need to enter the near-and short-range air defenses to destroy the enemy’s target. Ka-52 of the "flying tank" turns into an effective "sniper".
Mass production of "Katranov" should begin in 2020. As expected, the first cars will be designed for the Russian Navy, as well as for the Egyptian "Mistral". In addition, China showed interest in the Ka-52K in September, which has made a major breakthrough in the construction of modern landing craft over the past decade. In the Russian fleet, however, there are no fully-fledged, highly specialized helicopter carriers.
One of the options for the location of the Ka-52K is considered a heavy aircraft-carrying cruiser (TAVKR) "Admiral Kuznetsov". During 2016-2017, the helicopter “flashed” several times in news footage as part of the TAVKR wing, including during the cruise of the ship to the Syrian shores. It was reported that the naval "Katran" took part in battles with the terrorists of Daesh on a par with the VKS machines.
The Ka-52K helicopters completed the first stage of testing in marine conditions, the results of which suggest that the vehicles can be placed onboard the aircraft-carrying cruiser and successfully carry out the assigned tasks," Vladislav, Deputy General Director of Russian Helicopters for Sales, told reporters after the tests. Saveliev. - The helicopter has unique characteristics, but one trip to the sea is not enough to understand how its engines, units, avionics, control systems and weapons behave. maritime environment.
In the summer of 2017 the Katran was tested on the frigate Admiral Gorshkov, which means that this machine, in theory, has a chance to become a universal attack helicopter for all ships of the Russian Navy equipped with an appropriate landing platform. In perspective, the Ka-52K will form the basis of the aviation wing of the new helicopter carriers, which so far exist in the form of mockups.
This is a project of a universal landing ship (UDC) of the type "Surf" developed by the Nevsky Design Bureau. His layout was first presented at the forum "Army 2015". This ship with a displacement of 24 thousand tons will be able to take on board up to 500 paratroopers, up to 50 units of military equipment, as well as up to 15 landing helicopters Ka-29, anti-submarine Ka-27 or shock Ka-52K. The construction of the head UDC is expected to be funded under the next state armaments program. So, he can be a part of the Russian Navy until 2025 - just when enough “Katrans” are “gathered”.
The contract for the purchase of the marine version of the Ka-52K "Katran" is planned to be concluded in 2019 - the helicopters will be based on the landing ships of the "Ivan Gren" project. The Katrans continue the line of Kamov naval helicopters (Ka-25, Ka-27, Ka-29, Ka-31), which are in service with the Russian Navy. They are intended for patrolling, assault fire support during landing, anti-amphibious defense at the leading edge and tactical depth. From the Alligator, the Katran is distinguished by the presence of a shortened folding wing, which was modified to accommodate heavy weapons, and a blade folding mechanism, which allows the helicopter to be placed compactly in the hold.
