Playing 1.5 with no mods. I was tracking a TF west of Luzon on Christmas eve '41 and managed to put 2 fish in a Kongo BB. After some evading of the screening destroyers I popped up at least twice and observed the Kongo smoking and listing to port but still making about 10 kts. In looking over the other ships I did not see any others that had been hit.
Fast forward about two hours, I'm speeding at full and getting ahead of them again on my port side. I started to notice that the lead destroyer was getting well ahead of the main column, and as I looked back the smoking ship suddenly exploded. Multiple secondary explosions and she went down within a minute. But as she was sinking I noticed a second smoking ship in line and making the same course. There were two smoke plumes until the one sank. I'm almost positive I didn't hit two ships. Little confused. This was night conditions so I don't think an allied plane could have been out. Are there other allied subs out?
