Yes. It seems that PVO SV is getting the S-300V4, the first btln of which was delivered this year. Although it is possible that in the future a tracked S-400V will be developed, right now it's not even planned.@Feanor: with "older" I simply meant "older than the Tunguska" (I didn't konw yet that both systems entered service the same year).
Will all S-400 units be part of the Vozdushno-kosmicheskaya Oborona then?
The S-400 has been on combat duty since 2007 when the first unit was deployed near Moscow. A total of 6 btlns have been deployed so far, it seems. Allegedly another 3 btlns are to be deployed this year, though I think this is somewhat optimistic.Report: Russia deploys S-400 missiles in region bordering Poland, Lithuania - The Washington Post
Wasn't sure where to post this announcement of a S400 being deployed near Poland, I was under the impression that S400 wasn't yet operational.
