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 and participated in every major battle. For all of its official and unofficial names, the C-47 came to be known universally as the "Gooney Bird." C-47s remained in active military service long after the end of World War II. They played a critical role in the 1948 Berlin Airlift and saw action in the Korean and Vietnam wars.
