Not sure about that setup but I've had some luck with 1x BB, 2x CV, 2x DD, 1x CAV, reached boss on my third try but forgot to swap DD equipment=A rank only...

Standard fast BB equipment, 3 Reppus, 1 Reppu Kai, the two squadron planes, Saiun and Type 2 on the CVs, double attack setup, Radar and a Seiran for the heck of it on CAV, Depth Charge+Sonar for the DDs, they have a Turbine too but that doesn't really matter.

Even with Line Ahead, one hit from either of your DDs should be able to sink the sub at the boss node, unless they're really low-leveled.
