The Redut launchers are compatible with the S-400/Vityaz for the same reason that the S-400 launchers will be able to carry S-400 and Vityaz.
Note the land based Vityaz launchers likely wont be compatible with the bigger S-400 missiles because it is designed specifically to carry the 9M96 missiles.
The Land based system therefore has S-400 and Vityaz launchers... presumably the latter with 9M96 and 9M100 missile compatibility, while the former has 9M96 and compatibility with all the larger S-400 missiles including the 250km and 400km range weapons.
The thing is that the Vityaz is to replace the older shorter range S-300 batteries and has little need for the longer range missiles, while the S-400 can have the shorter range Vityaz missiles or the much longer range missiles.
The Vityaz on its own will be sufficient for protecting many targets but for major strategic targets the S-400 will be used.
Targeting will be in conjunction with the IADS including VKO data from satellites, ground radar and AWACS and aircraft like the PAK FA etc.
At sea there will be an IADS except it will include not just air defence data but data about space based objects and those on the sea surface and underwater and on land targets.
There is only one standard launcher for the S-300/S-400 SAMs (there is also the Shtil-1 vertical launch system for Shtil missiles of course) and it is standard from Corvette to Carrier.
The fact that it will likely never use a 400km range S-400 missile is beside the point... it will have the UKSK launcher bins too and may never carry a 2,500km range land attack Kalibr missile either... that is not to say it can't... it just probably wont.
They wont make a special UKSK launcher for Corvettes and a different one for carriers... both will be the same... that is the whole point behind standardisation.
Yes no doubt, but what I am looking for is specific mention of naval 48N6 use with Poliment-Redut.
The radar, network, everything is vastly different from land based system. Hell its different from 20380 (where it barely works!) to the 22350 (where the sensor suit is comparatively magic) .
I've always kind of assumed 48N6 was part of Poliment-Redut, but I am not sure now, especially with the VLS setup on the corvettes and frigates. It sure hasn't been tested, navally 9M96 has a long way to go alone.
The point behind a standard weapon system is that it is the same in every instance. On the Kirovs upgrade for example the main radars will be larger than the installation on a Corvette and there will be more than one 32 tube launcher on a Kirov, but otherwise they will be the same, which saves in manufacturing, maintainence, training, logistics, even ship design.
Saying a small ship like a Corvette doesn't ever need a 400km range SAM is like saying a small Corvette doesn't need a long range anti ship missile.
Never say never.
The 400km range S-400 does not need continuous tracking of the target for an intercept... in fact guidance can be handed off to another platform like AWACS or PAK FA.
