UPDATE: I got this one wrong. The reports of the R-29R launch clearly refer to the October 19, 2012 test launch of the missile.
On November 2, 2012 the K-433 Sv. Georgiy Pobedonosets submarine of the Project 667BDR/Delta III class carried out a successful launch of its R-29R missile from the Sea of Okhotsk to the Chiza test site on the Kanin Peninsula. The launch was part of an exercise that also included a launch of a cruise missile from the K-456 Tver submarine of the Project 949A/Oscar II class and launches of missiles from two surface ships.
Previous launch of a R-29R missile took place on October 19, 2012, also from the K-433 Sv. Georgiy Pobedonosets submarine. It appears to be the only one Project 667BDR submarine that could still launch its missiles - the last time a submarine other than K-433 participated in a test launch was in October 2009 - an exercise involved a launch from K-44 Ryazan submarine. The other Project 667BDR submarine based in the Pacific - K-223 Podolsk - has not participated in test launches since at least the early 2000s.
