To get B+ rank, you need either sink the boss or deal 2.5 time more damage than the enemy.

The later option is pretty much impossble with those 2 elite destroyer. Even with line ahead they can still hit if the sub evasion isn't high enough or if RNG say so.

Sub without remodel aka only 1 slot have little chance to sink a BB.

That just my opinion, since i dont have "a lot of luck".
