I haven't beaten it yet, but I've done pretty well loading each Heron with 2x Khopesh Rocket Bombers and 1x Spark Interceptor, 3 Tactical Lasers forward + 1 HVD + PD Lasers in the remaining slots and loading the Conquest with 2x Gauss Cannons + 2x Heavy Maulers on one side and 2x Devastators on the other side, with the energy slots filled with Burst/Heavy Burst PD and the missiles filled with Pilums. I put an ITU on the Conquest and filled the rest of the space with vents and capacitors, but I'm thinking about maybe spending some of the leftover OP on a Converted Hanger + Talon instead. I haven't touched the loadouts of any of the other ships yet. I deployed the two Herons, the Conquest, and a Vigilance for the starting fleet.
