1 - OASW setup (DEs with 60+ ASW, Isuzu, DD/CL with 100+ ASW stat) to kill or damage the subs first

2 - Line Abreast Formation (reduces accuracy/damage of attacks from subs)

3 - Vanguard Formation (new formation; boosts evasion of all ships in fleet at the cost of damage for the first 3 ships, the last 3/4 ships keep damage output however)

It's suggested that on all pre-boss nodes one should be using Vanguard formation in the first place.

Also, equipping the Strike Fleet Command Center (you should have gotten the basic gear necessary to do the quest(s) and get it) on your flagship will allow you to retreat a single Taiha'd ship...which is what those subs would do in most cases.

As far as mitigating the night-battle cut-ins;

Spotlight (on the Flagship ONLY) and Star Shells are said to reduce the Cut-In rate of enemy attackers.
