Use the best ASW gear you have on 2 ship girls, and go with double line on the boss node. Then you'll just have to pray the ASW ship girls don't get heavily damaged before they get to KO the sub.

In the Souryuu Kai Ni quest I equipped my other DD with ASW gear and the other one with main guns + turbine. As a result, I failed a few times as the ASW DD always got damaged before she got a shot in, and only when I equipped the other DD with ASW gear too, I managed to get S-Rank.
