Karel Doorman on De Zeven Provinciën
Airstrike specialistDoorman extends airstrike range, cruise speed, and plane HP via Bird's Eye View / Sea Wings / Iron Feathers so your bombers reach the target and survive AA. Cornelis van der Windt's Flame Storm trait adds bomb burning chance for more fire starts; Worf's Sky Attack trait raises damage on every projectile your aircraft drop. Treat the airstrike like a long-range torpedo: drop bombs across the path of a target rotating to cap or hiding behind an island, then use your main battery to punish whoever you've forced into the open.
