Russia has successfully test fired its Bulava inter-continental ballistic missile to its maximum range of 8,000 kms. The Defence Ministry said, the missile was fired successfully by the White sea-based Russian nuclear submarine Yuri Dolgoruky. The successful launch of the Bulava came after a string of setbacks suffered by this programme. Only eight of its previous 15 launches were officially declared successful. The Bulava, expected to become Russia's main naval strategic missile, is capable of carrying 10 warheads with a range of 8,000 kms.
