The Pacific War was fought across the largest battlefield in history, where tiny islands became stepping stones, aircraft carriers replaced battleships as the center of naval power, and logistics decided the fate of an empire. This episode explores how Japan’s early victories created a vast maritime empire that was difficult to defend, supply, and sustain. From Pearl Harbor and Midway to Guadalcanal, island hopping, submarines, and the slow collapse of Japan’s sea routes, we look at how geography, industry, fuel, carriers, and supply chains shaped the outcome of World War II in the Indo-Pacific.
