In his traditional December interview to the press, commander of the Strategic Rocket Forces, Sergey Karakayev, said that by the end of the year his service will complete deployment of five new Yars regiments - in missile divisions in Kozelsk, Nizhniy Tagil, and Novosibirsk.
The plan for 2015 was to deploy about 20 new ICBMs. The Kozelsk regiment, which began combat duty in December, received six silo-based missiles. This seems to suggest that the other four regiments did not receive a full complement of missiles.
Karakayev said that in 2016 the Rocket Forces will continue to deploy RS-24 Yars in five regiments - in Kozelsk, Novosibirsk, Tagil - and will begin deployment in Irkutsk and Yoshkar-Ola. Which is interesting, since Irkutsk was expected to receive RS-26. The total number of new missiles, according to Karakayev, is about 20.
UPDATE: At this point I assume that the Novosibirsk division received 12 new missiles, bringing its total to 21, and Nizhniy Tagil received six, so the total there is now 24.
