in Stock... No
with GWX... well ... kind of
GWX offers something that vanilla wont, convoys that will spawn with a few U-boats around them closing in... if your close enough you can join them in the attack. sadly though they cannot submerge, or fire torpedoes i think they can only use deck guns and flak guns against the enemy ships.... and since these convoys are escorted the action does not last longer than a couple of minutes and ends quite unfavorably for the U-boats.
so far in SH3 the only way to operate in wolf packs is to do so on multiplayer.
