To get a B-rank, you need to:
 * Survive 2 waves of bombers.
 * Equip a Zuiun in 2 slot sizes, which gives you a crap damage output and also has the high risk of being obliterated.
 * Land a hit while taking no damage at all. I don't believe for a second that a 2 plane slot sized Zuiun can sink the flagship or somehow do 250% more damage than the airstrike from the enemy.

If anything, that's quite a lot of hassle that doesn't improve your survival chances in practice, but only grants you a chance to get a B-rank. =w=
