US Nuclear sub has hit an unknown object in the South China sea
Can any ex-submariners explain how, if the boat hit an uncharted seamount, the crew or Commander might be held responsible?
If I understand this correctly, if the boat isn't pinging with active sonar - it can't actually `see' any objects in front of it, and is entirely reliant on it's INS and the accuracy of existing charts to know where it is - right?

We had a similar incident with HMS Superb in 2008. I've seen the damage - not public domain - and it made a mess of the forward free-flood spaces. In that case the CO mis read the chart.
Suspicion breeds confidence
Correct - but with the proviso that course/speed/depth selection should be appropriate for the level of accuracy and age of the chart.

Better idea and cheaper than cutting a window. Two glass bow caps, a nob off powerful searchlight in one tube and a scuttle in the rear door of the other tube to squint through. I leave the details to the spanner jockeys, I am more of an ideas man.
If that is too dear, what about a long white stick bolted to the front end?
Hmm - a searchlight.
Noting that you're joking (?) as someone who knows very little about submarine warfare, I assume that any emitted radiation - even frequency hopping - of any strength and spectra is probably pretty good at broadcasting one's position, visible light, LIDAR, same issue, and infrared.
If `seeing' ahead underwater without giving away one's position was possible, shirley someone would have done so by now...?
Recc - the passive fathometer stuff is intriguing.
Knowing a little about passive radar in the aviation world, I presume at the depths most submarines are at, there is not enough biologic or ambient noise to provide any sort of passive `image' of what is ahead.
Advice from those who know more appreciated.
Interested to read too about how out of date some charts still are.
I had assumed that areas of interest such as the South China Sea were mapped and know to the millimetre - but clearly not so!
This whole business of underwater navigation is fascinating stuff.

Especially the flying subs!
The transparent-hull "window-section" bow of Seaview was not rounded like a traditional submarine but was faired into a pair of manta winglike, stationary bow planes (in addition to her more conventional sail planes). This was added after the original B-29-like front with twelve pairs of windows on two levels was modified for "Freudian anatomically analogous issues."

You cannot blame him, my bet would be the second officer had been reassigned prior to sailing and took the keys to the lookouts locker containing their binoculars.
Mount a PNG camera on the front and a screen inside or some of those car reversing aid jobbies that detect walls etc..

More on the incident, its arrived safely at port.

Officially, in which direction does this ‘loss of confidence’ flow? Downwards from Fleet Command, who could have lost a submarine, or upwards from the rest of the crew, who probably didn’t enjoy having their boat rammed into a mountain.
