{| |} The Gotha WD.14, WD.20, and WD.22 (for Wasser Doppeldecker - "Water Biplane") were a family of torpedo bomber seaplanes developed in Germany during World War I. They were conventional biplanes, essentially enlarged versions of the WD.11 and like it, having twin engines mounted tractor-fashion on the lower wing. The wider fuselage of these aircraft allowed the pilot and observer to sit side-by-side in the open cockpit, and a second 7.92 mm (.312 in) machine gun was added in an open dorsal position. Hinges were added to the wings, allowing them to be folded for storage.
