I just loaded the beta update and played a first campaign mission. Subs were going into North Atlantic, via northern passage above Iceland, and my mission was to interdict.
Started combat at 5 knots, 150ft. Juliet and Alfa were bearing 120, heading 240. I went to silent running, and a slow decent. The Juliet, which was closest, maintained a depth of around 250 ft. The Alfa was at 300+ ft and descending. Both were below the layer. Neither was using sonar at the time.
After a few more minutes, I lunched a torpedo each, and continued at silent, with a slow decent. Both enemy subs started pinging. The Juliet maintained depth, while the Alfa continued decent and a turn. Torpedo hit Juliet and destroyed it. Juliet never fired back. The Alfa crashed into the bottom, and with its nose planted into the sea bed at a 20 degree angle(head down, a__ up), fired off two torpedoes which impacted the ground immediately in front of it. Eventually my torpedo impacted the Alfa and killed it.
My realism settings were the default.
