A Pacific war would advance by hubs

The proposed campaign is not a dash into Japanese waters. British forces would advance deliberately, seize usable harbours, and draw Japanese forces away from their own infrastructure. Slow Dale- and War-class tankers would move bulk fuel to forward hubs, while Leaf- or Wave-class ships carried it onward to the fighting fleet when necessary. That layered system sought to preserve mobility without making every support ship fast or exposing the entire fuel train to combat.
