USA

A type: Chetyrehdvigatelny long-range transport aircraft

Crew: 11 180 people and up passengers

The original Martian airplane Martin (Martin) was ordered by the US Navy on 23 August 1938 as a flying boat - a patrol bomber. Nevertheless, work on the prototype was slowed down by priority military tasks, and the first aircraft of the XRV2M-1 took off only in July of 1942. By this time, the task of distant patrolling was transferred to the finalized airliner Liberator (PB4Y) and the ubiquitous PBY Catalina aircraft, which forced Martin to convert a huge flying boat into an airplane to transport troops. In January 1945, the US Navy ordered 20 Mars, which received the new designation JRM-2, but only five were built before the day of victory over Japan.

They were followed by the sixth JRM-2 aircraft equipped with R4360 boosted "Wasp Major" engines, which allowed to operate the aircraft with increased take-off weight. Gradually, all previous instances also received new engines and all of them were given the designation JRM-3. The JRM series aircraft differed from the prototype KhRV2M with a mostly longer nose and one keel instead of the traditional two-kilo tail for the Martin company. All six aircraft were transferred to the NAS base in Alameda in the VR-2 unit of the Navy air transport service, and four surviving aircraft (one lost in an accident in 1945 and the second in five years in a fire) were declared obsolete in 1956.
