Desperate times call for desperate measures, and no time in history was as desperate as the time when the world’s most powerful nations were determined in destroying each other. It was time of the Second World War, and the allies were running out of essential resources needed to construct military and naval equipment. One of them was steel.
In the North Atlantic, the British fleets were taking a pounding against the German U-boats. Allied supply ships on their way across the ocean were being intercepted and sunk by German U-boats at an alarming rate. Planes could protect the ships, but they cannot be deployed in the middle of the ocean without aircraft carriers, and those things are massive and required enormous quantities of steel to manufacture, which was in short supply. What was needed was a way for aircraft to land and refuel without overtaxing already strained resources.
