That's true, but my understanding is that subs don't run active sonar when on patrol, since the sonar pings would give away their location. With the advent of nuclear subs that can stay underwater for months at a time, the location of "the other guy's" subs has been a priority for all superpowers. Not only our subs try to listen for the "other guys" but we have a whole range of surface ships and anti-sub patrol aircraft playing this cat-and-mouse game. NATO has even deployed a highly classified strip of listening stations on the seabed at "choke points" where "the other guy's" subs enter and exit their territorial waters.

It's not classified that subs have side scanning sonar, just like the survey ships.I just wish some of that data would trickle to NOAA et al so that we "skimmers" can get some of it, at least near the coast or near shoals to avoid running aground.Jeremy
