    ^^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?
