[Quillan]

I have recently seen a convoy with 4 escorts leave one behind at the site of the attack for over half an hour, lying at dead stop just waiting. This is without Trigger Maru, just the 1.4 patch and a couple of visual mods installed.

In SH3, tankers would be my top priority, however in this one they are near the bottom because they are so damned hard to sink! If there are any large passenger ships or troop transports they're first, followed by cargo ships in descending order of size. Every time I shoot at a tanker in SH4, they absorb the hit and keep right on going. I suppose it's understandable; a tanker is designed to sail with just as much liquid inside as outside the hull, so exchanging its cargo for water doesn't really make a lot of difference in the ship's floatation status. Occasionally I've found one that must have been carrying something volatile like gasoline that goes up from a single hit, but in SH4 it typically takes me between 4-10 detonating torpedoes to sink one large tanker.

If you're shooting from long distance (5-8 thousand yards), there's enough time to fire your forward torpedoes at the leading ships, turn 180°, and fire the rear torpedoes at the trailing ships before the first impact. It's unlikely that the convoy is wide enough that you can fire the forward torps at low speed, rotate, fire the rear torps at high speed, and have them all impact within a 15-20 second period though. This means some of the rear torpedoes will likely miss due to evasive action on the part of the ships.
