Douglas R4D-5 Skytrian

First ordered for the Navy in 1941, the R4D-1 was a cargo transport and served as the basic equipment for the Naval Air Transport Service (NATS), which was created on 12 December, 1941. In 1942, the South Pacific Combat Air Transport Service was formed, and used R4Ds to carry supplies into combat zones and airlift casualties out. In one month, over 22,000 passengers, 3,300,000 pounds of freight and 941,000 pounds of mail were delivered by this unit.

In addition to normal transport duties, R4Ds were equipped for various specialized roles, indicated by a special letter suffix added to their basic designation. For example, an R4D-4Q was fitted for radar countermeasures; the R4D-5E carried special electronics equipment; the R4D-5T was a navigation trainer; the R4D-5Z an executive or VIP transport and the R4D-6S was equipped for air-sea warfare training.
