On May 20, 2014 the Strategic Rocket Forces carried out a successful launch of a Topol/SS-25 missile that was used to test "new combat payload for future ICBMs." The missile was launched at 21:08 MSK (17:08 UTC) from the Kapustin Yar test site toward the Sary Shagan test site in Kazakhstan.
The Kapustin Yar-Sary Shagan Topol launches has been conducted quite frequently recently. The most recent launch of this type took place in March 2014. Today's launch is most likely one of the two launches that, according to Kazakhstan, Russia was planning to conduct in March. Kazakhstan's ministry of defense identified the missiles used in these launches as Topol-E (Тополь-Э).
UPDATE: The missile left a nice trail in the sky. Also, the video of the launch shows the large warhead section characteristic for Topol-E launches from Kapustin Yar.
