Is it just me or does this feel like another "we must stuff AI into everything, just because"? Inertial navigation has been around for most of a century, i.e. before GPS even existed, and is basically self-contained.
Not advocating one way or another, just that that's probably the thinking. Also, it's in vogue.
Every person in a submarine consumes valuable space/food/oxygen. Cooling and electricity on the other hand are easy to solve, when you have a nuclear reactor and a dead cold ocean right outside.
So if possible, AI will be used to perform these duties.
Using AI to predict where you might be based on crappy cheap sensor data and ocean simulations is never going to be precise enough. AI can't pull signal out of noise and uncertainty.
Yeah, but people with monies see this as "AI can help replace expensive milspec hardware with cheap COTS garbage plus some software magic pixie dust, for approximately the same effect [during peace time, in harbor]".
if it checks up with the map of how our brains learn to keep us upright, then we learn other side effects of how brains grow and learn
if it doesn't... then it's even more interesting because there's another confounding variable.
