For both airline and military use, the DC-3/C-47/R4D proved to be tough, flexible, and easy to operate and maintain. Its exploits became legendary. Every branch of the U.S military and all major allied powers flew the C-47. The U.S. Navy version was the R4D. The British and the Australians designated it the Dakota (DACoTA for Douglas Aircraft Company Transport Aircraft). The aircraft operated from every continent in the world.
