What of the turbulence just from the sub passing through the water? Can we distinguish it from the background noise?

- smileysteve 9y agoWithout active sonar? Not at a reasonable distance. Active Sonar can detect the water void/material difference with reasonable accuracy. U.S. sub streamlining and cavitation avoidance makes them nearly undetectable under running, much less full stop, and that's with a large prop rotating.
- clouddrover 9y agoIt's doubtful our sonar would even pick it up. And if it did, it would sound like whales humping, or some kind of seismic anomaly. Anything but a submarine.

- Merad 9y agoI recall reading something (I honestly don't recall where, so it's possible it was fiction) that discussed how Ohio class SSBNs are so quiet that theoretically, at least, they can be tracked by following the void that they leave in the natural background noise. Of course, the problem is that even if you can track it, you have to find it first. It's a big ocean.

Just force them to not be submerged. https://qz.com/915110/china-wants-foreign-submarines-to-stop-traveling-below-the-surface-in-the-south-china-sea-and-other-waters-it-claims/ https://qz.com/915110/china-wants-foreign-submarines-to-stop...
