Minor thread drift, but if you're interested in WWII sub warfare, Richard O'Kane wrote two excellent books recounting his experiences - "Clear the Bridge" and "Wahoo" (O'Kane was second in command to Mush Morton on the Wahoo - transferred off just prior to the Wahoo's last, fatal patrol).
Circular torpedo runs were a constant threat during WWII - sinking other subs in addition to the Tang and the Trinidad. Not quite the same as firing a missile at your sister ship...
