Britain's most senior sailor, First Sea Lord, Adm. Jonathon Band, said the underwater crash posed no risk to the safety of the submarines' nuclear reactors and nuclear missiles. But he offered no explanation of how the rare incident might have occurred.
The guy's title is "First Sea Lord." Holy crap, that is cool. I wish I were a Sea Lord.
Edit: I'm giving all Sea Lords a +1 for being BA.
