The ministry of defense is planning to buy insurance for ballistic missile and space launches in 2019-2021. According to an RBC.ru report, the tender documents (h/t DS) show that the plan includes two Sarmat launches, three launches of Yars, and four - of Topol.

The actual plan may be a bit different since other launches can be included in a different tender. But the last time the insurance information was found, in 2016, the number of actual launches more or less corresponded to the tender.

Judging by the number of planned Sarmat flight tests, the program is pretty far from reaching some kind of operational capability. We can be certain it will not be deployed in 2021.
