On 12 January 2012, it was reported the submarine had successfully finished state trials and that "Yury Dolgorukiy" would be ready for commissioning within the next couple of months. It was later reported that both "Yuri Dolgorukiy" and "Alexander Nevsky" would enter service in the summer of 2012. Dmitry Rogozin later confirmed that the submarine will be transferred to the Russian navy on 29 July 2012. "Yury Dolgorukiy" was expected to join the Russian Navy by the end of the year, but tests carried out during the latest sea trials revealed a number of technical flaws. Software glitches in the automated launch control system prevented further tests of the Bulava missile, the submarine’s main weapon. “We are expecting the "Yury Dolgorukiy" submarine to enter service in 2013,” then Defense Minister Anatoliy Serdyukov told Russian lawmakers at a meeting on defense issues.
