Just posting this because I thought it was an interesting (terrifying) story, and I only saw it in the office copy of Janes Defence Weekly. Back in December the Russian Navy had a dockyard fire on the Delta-IV class misile submarine Ekaterinburg - apparently wooden scaffolding caught light and set fire to the rubber accoustic tiles which clad her hull.
The exciting part is the Russian Navy (in the shape of Vice Admiral Vitko, commander of the Northern Fleet) just admitted that the boat had nuclear weapons on board at the time; they are "not always removed from a submarine before docking due to the complications of handling nuclear weapons." Glad I don't live anywhere near Murmansk.
(Link to original BBC news story with the denial that the boat was armed.)http://www.bbc.co.uk/news/world-16357000
