The Russian media quotes a source in the military as saying that the flight of the first of the two Bulava missiles launched from Vladimir Monomakh submarine on November 14, 2015 did not hit its targets at the Kura test site. The source said that the warheads did reach "the Kamchatka region", but not the designated targets. This suggests that the miss was fairly large.

UPDATE: Reports say that the missile was not properly prepared for the flight and as a result was damaged as it was leaving the silo. This, in turn, placed the missile on a wrong trajectory. It's not quite clear what it means. It appears that there was some physical damage to the missile that the guidance system was not able to compensate, but that was still not significant enough to abort the flight.
