Somewhat off topic.
What do big military submarines use these days to navigate?
Do they have nav systems based on topographic data of the sea floor?
(I dont know if it is mapped to the degree its possible).
Could that be read accurately with only passiv sensors?
I think you could read it perfectly with sonar whatever that may have
evolved into these days.
I guess they could reach depth where they can poke an extraordinarily
long antenna to the surface and talk to GPS systems?
(I dont know if such an antenna exists but it would make sense)

- ses1984 2y agoI guess they don't need to map the whole sea floor, just enough landmarks.
- ThinkBeat 2y agoThe more the better I would assume. I would guess some areas are boringly flat and easy, while other regions are full of obstacles and problems. I have read, but I cannot verify that the South China Sea is filled with obstacles and trouble, some they alleged China has created by sinking ships / crates / Supposedly to make it more difficult to navigate by submarine.
- ses1984 2y agoBig military subs are platforms for icbms. They don’t need to be in the South China Sea. They don’t need to be anywhere. They just need to be hidden.
