On December 26, 2014, the Strategic Forces conducted a successful launch of a RS-24 Yars missile. The missile was launched from a mobile launcher deployed at the Plesetsk test site. Missile warheads were reported to have successfully reached their targets at the Kura test site in Kamchatka. The launch, which was performed with support of the Air and Space Defense Forces, took place at 11:02 MSK (08:02 UTC).
This is one of the two missile launches that the Rocket Forces planned to conduct at the end of December. The other one is either the Strela space launch or a rumored RS-26 test launch. However, it appears that the RS-26 tests appear to be postponed, so it's possible that today's launch is the last in 2014.
