The Dolphin was introduced in 1930 by the Douglas company, and examples were eventually ordered by all the U.S. armed forces, with the first aircraft going to the U.S. Coast Guard. The Dolphins were used for transport and rescue duties, as well as security patrols along the U.S. coastline. Dolphins were recognizable by a aerofoil structure above the engines that was used to provide bracing for the two engines.
