On October 25 2016 the Strategic Rocket Forces carried out a successful test launch of an UR-100NUTTH/SS-19 missile from the Dombarovskiy basing area. The missile was launched at 11:58 MSK (08:58 UTC). According to a ministry of defense representative, the payload was "successfully delivered" to the Kura test site in Kamchatka.
This is probably another test of the Project 4202 hypersonic vehicle, similar to that conducted in April 2016.
The April launch helped finally identify the silo that is used for Project 4202 launches. It is the one at
50.972741, 59.550726 51.030808, 59.690054. UPDATE: I got the wrong silo. I also should note that the credit for finding the silo goes to anik, who also pointed out my mistake. (As you understand, there is no mystery in the method - I do try to follow all kinds of discussions and I do appreciate it when people tell me that I'm wrong.)
UPDATE: Or maybe it wasn't a Project 4202 test after all. The official ministry of defense statement says that "the goal of the launch was the confirmation of stability of key technical characteristics of missiles of this class during the period of extended service life." It well may be, but the "service life" could also be a cover story. It's hard to tell at this point. The last time UR-100NUTTH was launched in a dedicated service life extension test was in December 2011. That launch, however, was also part of the Project 4202 program. It is likely that later Project 4202 tests were used to extend service life of the missile (which was set to 36 years in 2014).
