摘要

A submarine at the centre of a near-catastrophe when it caught fire during maintenance at Murmansk in December 2011 is back at sea. The Northern Fleet strategic missile submarine K-84 Yekaterinburg made world headlines after hot work set fire to wooden scaffolding and ignited insulation material in the submarine's bow. It later emerged that the boat's arsenal of nuclear warheads was on board at the time.
