use your helos for spotting and ASW operations, always leave a few helos ready to sortie with torps and keep your ships as far away from the suspected subs as possible. This aint ww2, no need for depth charges or torpedo attacks we have helos as long beat sticks.
Try setting up 3 lines of buoys along your task force path or a spread around the suspected sub area, alternate between passive and active buoys. When you get a contact fly the nearest helo towards it and set it up as a spotter/listener with the dipping sonnar and a few active buoys. Then redirect the other helicpoters that are on stand by and armed with torps towards the target and let loose, try attacking from different angles too.
Remember, this is an ASW platform, nothing less nothing more.
