A modern nuclear submarine’s hull radius is about 20 feet.

Large blobs of fat (that would be humans) incinerate and are turned to ash and dust quicker than you can blink your eye. > Sounds gruesome but as a submariner I always wished for a quick hull-collapse death over a lengthy one like some of the crew on Kursk endured. --- While specifics differ, it would be over very fast.
