My biggest question after playing is about the sonar. It appears I am able to lock on a ship before firing the torpedo. If locked on before firing will the torpedos acquire the target? Do I need to re-acquire the target AFTER firing the torpedos? Do I need to lock on to BOTH the bow and the aft for the torpedos to acquire the target? It would be great for a submarine tutorial so we could actually test the developers ideas and design. THANK YOU FOR FINALLY ADDING SUBMARINES. Can't have WWI-WWII naval battles without aircraft carriers AND submarines.
