Russian Submarine Modernization Plans

The Russian CNO said today that they planned on eventually having a submarine fleet with four basic types of subs: an SSBN (the Borey class, already under construction), an SSGN (apparently a follow-on to the Oscar class), an SS (the Lada class), and, although the article doesn't mention it, probably a new class of SSN (maybe they'll start work on Project 885 again?). Expect a lot of talk from the Russians about their plans to modernize their subs during this 100th anniversary year of the Russian sub force, then expect not much to happen in actual nuclear submarine construction -- other that the Boreys. And if they stop working on those as well, no one will be sorry.
