{| |} The Gotha WD.27 (for Wasser Doppeldecker - "Water Biplane") was a patrol seaplanes developed in Germany during World War I. It was a huge, four-engine aircraft with the same general layout as the WD.22; a conventional seaplane with engines grouped in tractor-pusher pairs on the lower wings. Contemporary records show three German Navy serial numbers allocated to the type, but firm evidence of only one of these being built.
