The July 2008 START MOU data released recently indicate that there have been no major changes in the number of strategic launchers and nuclear warheads in the first half of 2008. The number of weapons carried by strategic submarines and bombers hadn't changed since January 2008 - 611 nuclear warheads are associated with strategic submarines and 884 with strategic bombers.
The number of ICBMs changed, but not dramatically. As of July 1, 2008 Russia had 415 missiles (15 fewer than in January), which could carry 1575 nuclear warheads. The change was due to continuing withdrawal from service of Topol/SS-25 and UR-100NUTTH/SS-19 missiles.
My estimate is that as a result of these changes the Russian strategic forces currently include 667 strategic delivery vehicles that can carry 3070 nuclear warheads.
As always, there is an issue of what is included into this count and what is not. The START treaty has very detailed and fairly complicated counting rules, which if applied strictly would give a different set of numbers. My approach is to give an upper bound estimate that would include systems that may not be operational at the moment but that could plausibly return into the active force (e.g. submarines in overhaul). At the same time, systems that are not yet ready for deployment (e.g. Bulava missile) are not included.
