I'm gonna check with Cookie on this and if any other submariner has any information on how a submarine is run, please drop a line. I would think that submarine duty is particularly hazardous and that strict discipline is maintained for the safety of the crew.
The crew aboard a U.S. submarine made dozens of errors before the vessel collided with an American warship in the Persian Gulf, an accident that exposed lax leaders who tolerated sleeping, slouching and a radio room rigged with music speakers, a Navy review found.
Hopefully, and I trust it is true, this example is the exception rather than the rule. From the Navy Times:
Navy investigators placed blame for the March collision on the submarine's ineffective and negligent command leadership," including what they called a lack of standards and failure to adequately plan for crossing the busy Strait of Hormuz.
I am wondering if the Navy is going to conduct a review of operational readiness and competency throughout the various commands. In any event, the investigation is still continuing.
Damage to a submarine involved in a grounding accident off the coast of Italy is worse than officials initially expected, sources told The Day of New London.
Most of the bottom half of the rudder is torn off, and gouges in the hull are deep enough to raise concerns about the structural integrity of the USS Hartford, the newspaper reported.
The damage occurred in October when the Hartford was conducting training drills in the channel as it departed La Maddalena and wandered outside the channel when the navigation team went too long without updating the ship's chart position, sources told the newspaper.
[...] The commodore of Submarine Squadron 22 in La Maddalena, Capt. Greg Parker, and the ship's captain, Cmdr. Christopher R. Van Metre, were both relieved of command Nov. 9. Six crewmen who were part of the navigation party received punishments for dereliction of duty.
