According to the ministry of defense, "the first regiment of Yars missiles in Kozelsk began combat duty." Which is interesting, since the military reported that the regiment was on combat duty in December 2015 (here is a link to the Interfax story).

What probably happened was that in 2015 the regiment began combat duty with six missiles and is brought to full ten only now. I was too optimistic in suggesting that the 2015 missile delivery plan meant that six silo-based Yars will be deployed in Kozelsk that year. Rather, it was the "normal" rate - two missiles a year. Still, if that was the case, the deployment should have been completed in 2017 - apparently there was another delay, besides production of missiles.

Now that the fist regiment is fully ready, one would expect to see more activity at silos of the second regiment.
