Surface ships are very noisy so submarines listen for other ships in the area before surfacing. They have dead zones in their sonar coverage, but can usually deal with that by turning to listen in those dead zones before surfacing. Nevertheless, there are occasional accidents.
- mpyne 5y agoSurface ships are not always noisy. This is especially a problem with supertankers if you they are head-on to you, they can be hard to hear from underwater, especially with the high level of noise from the surface around the supertanker. This was a contributing factor to a collision in the Mediterranean about a decade or so ago.
