Recently opened 5-3 and manage to finish it using 5 subs (3 SSV, remodelled I-168 and Maruyu, still don't have I-401 since passed lot" 1 day after Arpeggio event ended), 2 subs knocked out to heavily damaged every time by Ha-class DD depth charges when RNG-sama gives D-F-I loop route.

Which formation should be use to increase survivability of subs when encountering those DDs, or maybe bringing fast ships are more preferable than them?
