So here's a thing: The model with the containerised Calibr has the helipad forward of the stern where the containers are.
The model at the recent military show has the helipad right at the stern (is it shorter than the earlier model?)
Does possibly look like there are still covers there in the drawing & it does have a highlight with missiles (uran?), containers, mini-sub & towed sonar (?) there.
Where is the Igla launcher? Its supposed to have 1 of the Gibka launchers like on Buyan-M
but I haven't been able to identify it in any pics yet.
