A RSM-54 Sineva/SS-N-23 Sineva missile was successfully launched from the Yekaterinburg, a Project 667BDRM/Dela IV class strategic submarine, of the Russian Northern Fleet. The missile was launched from beneath arctic ice towards a target site on the Kanin Peninsula on the 27th April, 2011.
Russia has test-fired another three intercontinental ballistic missiles, a day after claiming a distance record for a missile fired from a submarine. President Dmitri Medvedev, who watched two of the launches, said they proved Russia's missile defences were strong.
