Couple of notes:
 * 1) As 4-slotters tend to overcap ASW, Type 3 Active Sonars are preferred as they add more accuracy. And against Submarine Princess, this really matters.
 * 2) BBVs do ((1.5*36)+8)*1.3*(0.8 or 1.0 or 1.2) = 64, 80.6 or 96 damage for Head-on, Parallel and Green T respectively if 4 Autogyros are equipped, or 67, 84 or 101 damage for Head-on, Parallel and Green T respectively if 3 Autogyros and 1 Type 0 Passive Sonar (Ranking-exclusive equipment) is equipped. So don't think that the BBVs can't ASW-cap.
 * 3) It bears mentioning that the formation modifier for Combined Fleet ASW Formation I is also 1.3.
