The group first looked at the existing pool of military planes, none proved satisfactory, so they began looking outside of the Air Service for a plane that could be fitted with interchangeable landing gear, wheeled and pontoons for water landings.

Since the plane was an existing model, Douglas stated that a new fleet of planes, which he named the Douglas World Cruiser, could be delivered within 45 days after a contract was awarded.

All the internal bomb carrying structures were removed and additional fuel tanks were added to various parts of the plane.
