Periscopes haven't been combat critical on submarines since slightly after WW2. They rely mostly on sonar to detect enemies, not vision - and of course they would. Periscopes are useless against submarines, and if an anti-submarine ship is nearby, you wouldn't go to periscope depth putting the submarine in a perilous position, and showing it off at that. |
