The fire sounds like it was forward as the sonar dome was destroyed in the blaze. The fire took place on Dec. 29 at a dry dock in the village of Roslyakovo. Reportedly, wooden scaffolding around the K-84 "Yekaterinburg" caught fire and spread to hull insulation. I imagine that much burning rubber had to release some nasty fumes. The vessel had to be submerged to put out the fire. Nine people were injured.
Repairs to the sub are expected to cost in excess of 30 million dollars (over a billion rubles) and take at least a year. That is one heck of an oops.
Doesn't sound like the missiles, even if they were aboard, were in much danger so long as the crew kept their heads.
