The Rocket Forces announced the plan to add two regiments to the Topol-M force in 2010 - a regiment of silo-based missiles in Tatishchevo and a regiment of mobile missiles in Teykovo.
A regiment of silo-based missiles includes ten missiles and a mobile regiment includes nine, but it is not clear if complete regiments will be deployed. The Rocket Forces earlier said that the sixth regiment in Tatishchevo will be completed in 2010, so we may see the number of silo-based Topol-M missile reaching 60 by the end of 2010.
With mobile missiles, there is a bit of confusion about Topol-M proper and its MIRVed version, RS-24. The number of mobile (single-warhead) Topol-Ms was supposed to reach 18 by the end of 2009. In addition, three RS-24 missiles were supposed to be deployed in Teykovo as well. However, we haven't heard about any deployments in Teykovo in 2009.
The bottom line is that unless we get a clearer picture of what happened in Teykovo in 2009, it is quite difficult to make a good estimate of the numbers.
