I've sunk liberty size (7k tons) sips with one or two torpedoes. I have seen some ships sink slowly after one hit without any encouragement from me. I've also seen some ships stabilise their damage after two hits and not get any worse and sail on regardless. I think the flames are disconnected, like they were in SH4, from the actual progressive damage, so even though a ship is on fire, the fire only indicates the amount of damage done so far, not damage being done progressively, which you could easily imagine.
