The flight of the prototype took place in 1942, and a short series production was carried out in the years 1946-1947. In total, only seven machines of this type were built! The drive was provided by four Wright R-3350 engines with a power of 2500 HP each. The machine was 35.74 meters long with a wingspan of 61 meters.

The Martin JRM Mars plane was created for the needs of the US Navy as a long-range transport flying boat.

Initially, it was planned to acquire 20 machines of this type, but due to the imminent end of hostilities, the order was reduced. Stock Martin JRM were primarily used to transport soldiers over long distances and operated primarily in the Pacific. After the end of service, four of them were converted into fire planes
