While a feet of engineering, purists point out this was not fully submerged. The sub returned to the surface regularly for navigation, poking up its periscopes for star fixes and photographs. The ability to navigate the world ocean totally free of the surface, perhaps spending months under ice, had not yet happened.

How does a modern submarine navigates today?
Then also some other equipment like a magnetometer and magnetographic maps of the world to provide references to counteract the drift in any inertial navigation.

Very classified so we only know bits and pieces. "Inertial navigation" is part of it - basically very precise dead reckoning. Using specialist equipment like laser ring gyros to get precise measurements.

My dad was based on a submarine when he was in the navy. He didn't talk much about it but maybe because it was just kind of boring. They would go to the North Pole/icecap and just sit under it for three months.
One thing I do remember, everyone had to have working knowledge of all components on the sub, how they remembered that is beyond me :)
I am curious about his size, I never saw anyone who worked on subs. I felt they would be smaller on average in size due to cramped conditions. I wonder if that is true ?
Nuclear Submarines are an outstanding marvel of technology and the men serving on them are the most trained and psychologically conditioned of all people. From a philosophical/psychological/physiological pov i think of them as sharing a lot of the characteristics of hardcore monks/yogis. Both must have absolute self-control at all times and follow a strict unbending discipline. The following are some good resources;…
Philosophically and psychologically I don’t think any monk of any religion would approve working on a weapon capable of razing cities to the ground.

Thank you for the information - and what about communication? I don't think they have an antenna that reaches out to the surface?

A few years ago there was a short podcast on NPR about what it took for someone to be trained for submarine service. From what I remember, that training was far harder than any other navy training.

For training, what he said is that they all had three(?) areas/responsibilities that they were trained in so that if someone got sick or died someone was available to take their place.
One of his jobs was actually to maintain one of the first computers installed on a submarine. He told an admiral that it was a big piece of shit because he spent half of his time replacing burned out vacuum tubes. The computer analyzed ship sounds (screw, engine) and could tell them the ship that was passing overhead.

I play music with a guy who was a weapons officer on a nuclear sub. I’m 6’/1.8m, and he’s noticeably taller than I am.
