Charging a DD on the surface is a good way to ingest a couple of 5" shells right in the conning tower. They're accurate to about 5000 yards. Subs have been known to have indigestion and be unable to swim afterwards. Down the throat is chancy enough without 50 knot closing speeds.
It's about a one in three proposition in the best of circumstances, where you wait at periscope depth running away from the DD at ahead emergency (reducing closing speed and encouraging him to increase speed) and wait until 500 yards to shoot. Immediately upon shooting you dive and turn left or right. You might lower the scope too.:rotfl:
Your way works in the movies, but SH4 it's too dangerous and not accurate enough.
Try it a few more times and see if I'm right!
