The Strategic Rocket Forces will receive a new rail-mobile ICBM after all. The new missile system, named Barguzin, is being developed by the Moscow Institute of Thermal Technology.
The institute began working on the missile in 2013 and so far the project seems to be moving forward without delay. It appears that the MITT is confident that it could complete the development quite quickly and prepare the missile for deployment as early as 2018.
The word is that the scale of deployment of the new missile will be quite limited - no more than one division, which means 9 or 12 missiles. I'm not sure that this would justify the development cost.
In case you are wondering, barguzin is a strong eastern wind on Lake Baykal. It's also a river there, but I guess it's the wind that the designers had in mind.
