"The submarine-based Bulava (Mace) missile has been billed as Russia's newest technological breakthrough to support its nuclear deterrent, but the repeated test failures are an embarrassment for the Kremlin. The missile failed in its 13th test on Wednesday morning, Russia's leading economic dailies Vedomosti and Kommersant reported on Thursday, quoting sources in the military-industrial complex. Hours later, the Defense Ministry admitted the failure, saying the launch had been made by the Dmitry Donskoi nuclear submarine from a submerged position in the White Sea. "It has been established ... that the missile's first two stages worked as normal, but there was a technical malfunction at the next, third, stage of the trajectory," a Defense Ministry spokesman said." - bob
