    It could have been destroyed by a Osa radar guided system or a tor or heavy machine gun.

    Who told you it was stinger.

    Ukrainian air defence is not huge but still powerful.

    Those little soviet system are nastier than S-300. Specially for choppers.

    Twin barrel 23mm cannon are vastly more capable than 50 cal HMGs and are small enough to mount on the backs of quite light mobile vehicles.

    OSA is a command to line of sight missile and could not be stopped with flares or chaff or DIRCMs.

    Even in its current state it is better armed for air defence than any HATO nation including the US.

    "Attack in front - Stinger!"

    Unique footage of the work of the on-board defense complex L-370 "Vitebsk" from the cockpit of the Russian attack helicopter Ka-52 "Alligator" during the cover of the landing of the Airborne Forces at the airfield near Gostomel, Kiev region, February 24.

    Saw on another forum discussion of "vibration issues" of the ka-52 but I dont want to even deal with the people on that forum as their objectivity went out thr window with this current war. They linked to another NI tier article discussing it but all i have seen are two videos of body vibration. Anybody know what is going on? Were these aircraft damaged? Anyone with actual nonbiased info would be much welcomed.

    Early models of Ka-52 had some issues with vibration of the goems imaging system. It was fixed later as I believe the final outcome was the Ka-52's ended up with same optical system used on the later models of Mi-28's which were much better. It was also part to streamline parts and reduce overall costs. It is possible that, as we seen, many older Ka-52s used in the conflict never got the replacement devices and just operate the same optics originally in.

    Would it be possible for you to please post the videos you are talking about? Thank you

    Here is a tweet with one of the videos. I checked the forum and I wasn't surprised at the bigotry but a few old timers there finally started talking sense. I finally am getting an idea of what is going on in the video. Sounds like battle damage. Potentially a mistake in maintenance but I'm going with the former from all I could gather. Btw I've only seen two videos like this before, this being one of the two.

    Where did you read "common sense" of the trolls of that worthless post? Idiots just show and manifest their idiotism to the world by constantly mentioning and believing in "washing machines".

    Vibration is an issue for all types of helicopter... one of the main reasons against having mast mounted optics is because vibration made the original optics pretty useless without some serious stabilisation equipment.

    These days gyro stabilisation equipment is widespread and also software based image stabilisers are getting very good too.

    The influx of more than 10 thousand Stingers should have led to the wiping out of the entire Russian helicopter fleet in fact proponents of Stinger and Starstreak etc suggested the era of the helicopter and CAS was over because it was just too dangerous.

    Similar comments about armoured vehicles when talking about Javelin et al... with all the stuff HATO has sent and all the stuff they already had which to be fair was probably rather more practical, I would say aircraft and armoured vehicles are doing pretty damn good really.

    Some problems with Ka-52 suppliers:
    https://t.me/Viktor_Murakhovskiy/271

    An independent hydraulic unit is installed on the front landing gear of the Ka-52 helicopter, designed to damp vibrations of the wheel pair "shimmy" type when the helicopter moves along the earth's surface. This unit is called a damper. It is a purchased product and is manufactured at Gidromash PJSC (Nizhny Novgorod) with a guaranteed resource of 750 helicopter landings.
    During the operation of Ka-52 helicopters from 2015 to 2020, there were 12 cases of destruction of these dampers within the warranty resource.
    Since the damaged damper is under warranty, the operating organization draws up a reclamation act. A service team arrives, dismantles the destroyed unit, and it is sent to the damper manufacturer. PJSC "Hydromash" is conducting a study of the damper, the results of which conclude that its destruction is due to improper operation. For this reason, the reclamation act is rejected, and a new damper is offered to the operator, of course, for a fee.
    As a result, everyone is happy: the operating organization restored the aircraft fleet to good working order, and the manufacturer made money on it.
    All this "idyll" continued until a pair of destroyed dampers was sent for research at the Research Center (Lyubertsy) of the Central Research Institute of the Air Force of the Ministry of Defense of Russia (the former GosNII ERAT - the Institute for the Maintenance and Repair of Aviation Equipment of the Air Force).
    As a result of the study, it was found:
    • First, the reason for the destruction of the dampers of the front landing gear legs of the Ka-52 helicopters was the presence of defects (contamination) of the material of the brackets in the form of segregations (accumulations) of oxides and oxide films in combination with an unfavorable orientation of the texture (fiber direction) of the material in the region of the lugs;
    • secondly, the presence of such contamination of the material, including lugs emerging on the surface, and the unfavorable direction of the material fiber are unacceptable violations of the requirements of OST 1 90073-85 “Stampings and forgings from aluminum alloys. Specifications";
    • the third is a manufacturing defect, due to the imperfection of the adopted technology for stamping damper brackets and threatens the flight safety of Ka-52 helicopters;
    • Fourth, it is very likely that similar material defects led to the destruction of the brackets on another 8 dampers sent in the period from 2015 to 2018 under reclamation acts to PJSC Hydromash.
    The results of the study were communicated to interested organizations a year ago. During this time, no objections from industrial enterprises were received either by the Institute or by the command of the Aerospace Forces. This circumstance suggests that the true cause of the destruction of the dampers was known to the manufacturer, but the current system allows them to earn money on defects in their products. And if the system allows, then why not take advantage of it? We have market relations.
    The industry should be left only with the overhaul of equipment with its modernization and the supply of spare parts. Calculations have shown that in this case, the costs are reduced by almost four times, and the terms for the restoration of equipment are reduced by about five times.
