Here I found my:
First time when I was searching it I patroled few days, found some taskforces, alone merchants and one unenscorted convoy, spent all torpedoes and returned to base. Second time I just entered designated patrol area, few ingame hours and "Smoke on the horizont!". First I thought it was another DD-only Taskforce, but decided to wait to let them come closer and I saw huge carrier. They was going right on me, so i dived on 150 meters letting escort to pass above, floated to periscope depth right inside convoy, salvo shooted torpedoes, only one hit, but i think it was critical (thx to critical hits mod
) - carrier blew like a keg of gunpowder!
Oh, and here is big topic about this mission:
