Its not the pressure, but the fact water blocks radio waves. Submarines can’t get GPS signals or transmit their location. Submarines have to rely on other means

- yayitswei 3y agoWhat about a signal flare that floats to the surface?
- Mandatum 3y agoI believe at a certain depth some things compress, density increases, buoyancy becomes negative - and they sink.
- Allph0r 3y agoThey have locator beacons size of a thermos (that ping powerfully using particular frequencies) which they fit on flights etc... i believe some can be received a couple miles+ down in good conditions like are seeing now.
- eternityforest 3y agoBut clearly not everything sinks, or the sub would never be able to surface. If it's just a matter of engineering work, that's kind of literally their job.
