    ^^That looks more like a transport helicopter rather than an anti-submarine one.

    Just like ka-27, it will be a family of helicopters rather than just an ASW helicopter.

    That's not Minoga, that's old concept for high-speed helicopter

    Minoga is grey one on the right:

    Why don't they just take advantage of the Mi-38, which is already available, to develop an naval version of it?

    Because it is overly large for the naval shipborne role for many vessels.
    Its fuselage without rotors turning is 20 meters long, and has a rotor diameter of over 21 meters.

    Also coaxial helicopters are much more stable than standard ones

    And safer to be around

    The size of the helicopter will be tied to the ship's standards, and the machine itself will receive modules for installing weapons.

    That makes it sound like it will be the same size as the Helix helicopters, while the modules make it sound like an enlarged Ka-226 type design with modules that can be replaced to change role.

    In contrast the image above appears to be more like a naval Mi-38 with coaxial rotors and a pusher prop...one of the land based high speed helicopter competitors...

    The Mi-54 springs to mind for some reason...

    Why don't they just take advantage of the Mi-38, which is already available, to develop an naval version of it?

    Because it is much bigger than any model Helix and would not fit.

    The added problem is that the Mi-38 has a tail rotor which is rather dangerous on a ship.

    As PD mentions the coaxial rotor design handles cross winds better... a helicopter with a tail rotor generally has to turn its nose into the wind and then nod or raise its nose in the oncoming wind to maintain station... close your eyes and imagine what happens to a helicopters tail rotor when the pilot swings his nose into the prevailing wind and nods his nose up and down... who likes Sushi?

    According to Flateric, this is a generic model that does not correspond to the latest layout. Whatever that may mean Smile

    It means it just a toy for decorating the model of ship they presented. It is there to show that you can carry different classes of helicopters.

    If you want to see the real model of Minoga then you go where choppers are exposed, not where ships are exposed.

    Shipbuilders have nothing to do with helicopters.

    The different developers do communicate because the new Minoga, which we really don't know a lot about, but we do know it will have to operate from ships that currently operate Helix helicopters, so its dimensions need to be similar to the current Helix... and on that model we can see the Mi-38 is similar but longer body fuselage and with a tail rotor sticking out.

    It is safe to assume Minoga will likely have the cross section shape of the Helix so it can continue to use lifts and hangars designed for that aircraft, but that it will likely have a longer fuselage for more internal space... coaxial rotors because the hangars are tall and the lower decks are tall to accomodate the Helix and Hokum types already.

    I suspect the fundamental change will be a rear ramp door which might make a pusher propeller a non starter, but then a high speed transport helicopter that goes 500km/h supported by Hokum helicopters able to go 300km/h does not make much sense anyway.

    The Minoga is likely to be a cross between a Helix and a Mi-38 with the latters increased cabin length and rear ramp door, while the rotors will be from the Helix and likely with more powerful engines.

    The main difference between the Ka-25 and Ka-27 range was more cabin volume and much more powerful engines too...

    There is not a lot wrong with the Helix, but a rear ramp door and more internal space would be obvious and easy improvements that would allow them to continue using the same ships with the same facilities and using the helicopters together.

    Personally I would love to see a navalised Mi-38 take over the role of the Mi-14 which was a very capable anti sub and maritime patrol platform.

    A ship shaped lower fuselage optimised for landing on the water would be useful but would require helicopter roof mounted electro-optics... and perhaps a mast mounted radar array based on experience with Mi-28NMs.

    It definitely corresponds to the chopper in the right of post 53 picture.

    Obviously there is nothing categorical about a model.

    Models of new potential Soviet aircraft carriers in the 1970s had MiG-23 model fighters on them just as an example.

    Turned out that with more thrust and wing area that MiG-29s and Su-27s could be modified for the job more easily and so there were no carrier based MiG-23s.

    I am just relieved there are no VSTOL fighters... that would be terrible.
