The Martin 193 was a design for a giant cargo seaplane, conceived in 1942 as part of the Sky Freighter concept for colossal flying boats able to carry troops and freight across the Atlantic while U-boats were sinking Allied merchant ships. It was essentially a 40 percent enlargement of the Martin JRM Mars, with a longer hull and wingspan, six radial piston engines and a takeoff weight of about 250,000 pounds. The Hughes H-4 Hercules won the competition, the end of the Second World War removed the urgency, and Martin's idea of a civilian version found no interest among airlines, so the aircraft stayed a design.
