The USS Miami was my first boat, 1998-2003.
Yes, there is a possibility this was bedding. Usually though, when you go into an overhaul like this, all the bedding is removed. The mattresses may or may not have been removed.
There is a lot of wiring that is bundled together around ships. There is also quite a bit of temporary equipment that is brought on the ships during overhauls like they were doing that could have been the source as well.
There is no "fire suppression system" as you might imagine. Normally all firefighting would have been taken care of by the 130 man crew. Portable extinguishers only go so far, and it seems that this was far beyond a few extinguishers.
I stood my fair share of watches in the engine room. I knew this day would come sooner or later. I'm sure that the nuclear operators stayed at their watch stations during all this. This is a hell of a way for the Miami to go out.
Can do, will do, glad to.
First to fire, twice to fire.
