Below, ironclad battleships exchange fire on a churning sea while squadrons of dart-shaped aerial fighters swarm through billowing smoke. Tricolor flags snap from the gondola of the great dirigible as it fights for dominance of both sky and sea in this breathtaking vision of future mechanized warfare.
