Why is visual out? Cameras are cheap
- bayindirh 5y agoBut water is not always transparent or clear enough. Also there's not enough light all the time. Also pressure proofing cameras are not cheap I presume.
- ethbr0 5y agoYup. There's not much light below 100m. Certainly not down to 500m+. Which would also be 50atm+ worth of pressure.

- paranoidrobot 5y agoThey have upward-looking cameras, at least on some of them. You can see it in the last Smarter Every Day video[1] where they're talking about surfacing a submarine in the arctic ocean. At several points you can see a video monitor showing an upward view of the ice.

If someone is about to cross that area you'd need some other way of detecting them.
- jedc 5y agoThere’s special equipment/procedures for surfacing in the Arctic. That’s another really dangerous place to operate. (Default action in a submarine emergency is to get to the surface. That’s… NOT easy when there’s ice above you that’s potentially too thick to punch through)
- runsonrum 5y agoIsn't everything expensive for the military?
- tshaddox 5y agoIsn't it dark?
