"12"^^ . . "The Gotha WD.11 (for Wasser Doppeldecker - \"Water Biplane\") was a torpedo bomber seaplane developed in Germany during World War I. When the general configuration of the Gotha WD.7 proved promising, Gotha set to work designing a much larger and more powerful aircraft along the same general lines. Like its predecessor, it was a conventional biplane with twin engines mounted tractor-fashion on the lower wing."@en . .
