New BB fighting technique with an S boat deck gun

[Snarf]

First off, I'm using a new super sugar boat mod I'm working on, I went to work on a BB/CV group. I sunk a Shokaku, Hiryu, Ise, 5 Shiratsuyuu/Mutsuki DD's, and 3 cruisers. I damaged a second Ise, and completely crippled a 4th cruiser, the tanker and last DD went off on their way, and I hung around with no more torpedoes trying to figure out how to finish off this Ise without getting obliterated. My technique: staying outside 3000 yards (to keep away from machine gun fire) I ranged from periscope depth, blew ballast, dialed in range as fast as possible on deck gun, fired two, and crash dive. Then I interrupted the crash dive at periscope depth, ranged in, adjusted speed, blew ballast, fired two and repeated. Every shot was a hit, and every time the Ise would fire, he would have to readjust, but I was already back under as he fired his first miss. I repeated this until I was at about 10% remaining compressed air and the batteries were almost completely flat, but finally I hit a magazine and the Ise light up like the 4th of July, started capsizing and went under. I was running low on fuel so I left the last cruiser to fend for itself.
