Sea-based SAM 9K96 "Redoubt" in the amount of 30 blocks of 8 launchers and SAM 42S6 "Morpheus" short-range.
Well 30 times 8 tubes is 240, but we know that those tubes will likely have a mix of 9M96 missiles (better known as S-350), but also short range 9M100 missiles... but the 9M100 missiles are smaller than the 9M96 and you can fit 4 9M100 missiles in the tube one 9M96 goes, so with 240 launch tubes that means between 240 S-350s of up to 150km range, or 960 short range 9M100 missiles.... but obviously they would likely used a mixed load of both types.
Among other things, the Admiral Nakhimov tark will receive unified UKSK 3s14 (30x8) launchers capable of launching various types of missiles, such as Kalibr, Onyx and Zircon.
The original plan was for 10 UKSK 8 tube launchers... they would have to remove the Rif-M and the SS-N-14 launchers in the front of the ship to fit 30 UKSK launchers...
They would carry anti sub ballistic rockets in those UKSK tubes.
Will be interesting to see the complete details of the upgrade... because the Redut probably replaces the S-300F Rif system, but it should also have up to 8 Pantsir systems which is 16 30mm gatling guns and another 256 anti aircraft missiles, plus I would suspect a few Duet turrets around the place too.
It is a very big ship that had a old of old generation electronics that were bulky and huge... we are talking about room and building sized computers that could be replaced with a modern cell phone or tablet computer, so there should be a lot of space that could be made available for a range of different weapon types.
Also important to remember there are other systems and weapons that can go in these multipurpose launch tubes... for the UKSK-M that included jammer rockets and all sorts of other potential things like PAKET anti torpedo weapons etc etc.
