This was to be the Martin Mars, a 140,000-pound behemoth that was the largest plane in the U.S. military inventory until the arrival of the B-36 intercontinental bomber in 1947.
The Mars was originally conceived as a "sky battleship" or "flying Dreadnought," armed with multiple gun turrets, capable of flying long distances with huge bombloads (and Marine paratroopers as well).
Martin recognized this and began work on a 145,000-pound landplane using the same engines and wings as the JRM-1; the Model 199 was to have a floor level no higher than that of a truck.

In 1959 the largest flying boats to have ever served with the U.S. Navy were all sold to Canada for use as fire-fighting water bombers, where some still remain in use some forty years later.
