Flight test of a Project 4202 vehicle
Russia appears to have conducted a flight test of the Project 4202 vehicle on February 26, 2015 from one of the silos in Dombarovskiy. Project 4202 is believed to be some kind of a hypersonic vehicle that will be delivered by the UR-100NUTTH/SS-19 missile. (See also the earlier post.)
Project 4202 launches have never been officially acknowledged, but bits of information appear here and there and there are enough dots to connect, so there is a fairly high degree of certainty that the launch indeed took place. (I must say that I can claim no credit for finding the dots - most of them have been discovered by others.)
First, TsENKI (Center for Operation of Space Ground-Based Infrastructure) in its 2014 acquisition plan listed two Project 4202-related contracts. In the document, the launch is scheduled to take place in January 2015, but it was later postponed. Industry sources were said to confirm that the test was moved to February.
And indeed, on February 26, 2015 a note on a Russian site, which is known to be well connected and generally reliable, said something to the effect that a test is upcoming. The post has been removed since, but only after it was updated to say that the test was unsuccessful.
Finally, a number of people have found a message posted by someone from Yasnyy (which is the name of the city at the Dombarovskiy missile base) later on February 26. The author said that in Yasnyy people felt a missile launch that took place around 13:00 local time (that would be 8:00 UTC).
The February 26, 2015 launch is not the first flight test of the Project 4202 system - at least one took place around September 26, 2013. It appears that another test took place some time in 2014, maybe in September. All we know about the 2014 test is that there is an unaccounted event in the official record of launches conduced that year (the 2013 4202 launch also was not included in the official account). None of the test appear to have been successful.
I guess we'll have to wait for a successful flight test to see an official report on Project 4202 and learn more about the system.
