Actually, IMO the stock SH3 convoys are smaller than would be historical; I actually think they're about the right size for historical Japanese convoys. Happy to be corrected on this, but if I'm remembering Blair correctly it seems like there were lots of six to ten-ship convoys.
And there were at least two enormous ones - the invasion force for Malaysia shipped in two groups of about (IIRC) 40 transports each. Historically, though, no allied sub came in contact with either of these main bodies. Again, willing to be corrected on that....
Animations would be really cool, but they might eat up too much processor. The game has to be marketed to the middle of the bell curve - most people don't have high-end machines. So.... I'm with Sailor Steve; I don't know either.
