The Russian Defence Ministry has published a video of an RSM-56 Bulava missile being launched from the K-535 Yury Dolgoruky Borei-class submarine.
The test-launch, which took place in the Barents Sea, was described as successful after the missile destroyed its target.
The R-30 Bulava is a solid-fuel ballistic missile developed expressly for Project 955 submarines. It carries 10 warheads of 150 kilotons each and has a range of 8,000 kilometres (5,000 miles).
