That's more than we can mod I imagine. Early war, though, they would have to team up to drop a lot. The 36 DCs carried by many IJN DDs was the count AFTER they had 4 throwers added. Apparently early in the war they carried far fewer than 36 DCs. The early war Kaibokans carried only 12 DCs. The minesweeper in game? On non-escort duty it carried TWO DCs. Not 2 racks, 2 depth charges. I think from a gameplay standpoint I'd not have any ship carry fewer than maybe 6 DCs.
OTOH, it might be interesting to see the effect of a really crappy crew on a really capable ship.
Perhaps I should try Bungo Pete with his skill set to AI=0. I'd be looking for lots of attacks, but no where near me
If it worked, we could make some ersatz escorts, give them GREAT hydrophones, but awful crews. They might detect you and drop a mile away...
