Gothaer Waggonfabrik A.G. (Gotha) built both twin-engine bombers and a series of seaplanes.
Production aircraft from the Great War or shortly thereafter include:
- Reconnaissance Biplanes
- Seaplanes [note 2]
- The war ended while the G.VIII/GL.VIII was still undergoing prototype evaluation.
- W.D. likely stands for Wasser Doppeldecker, or 'Water Biplane'
- Only the prototype W.D.5 was built.. It was sent to Turkey on 13 July 1916.
- The W.D.6 was the company designation for thirty Brandenburg NW's built under license by Gotha, aka the "Brandenburg NW(Go)".
- Only a single WD.8 was built in late 1915. It was delivered in Feb 1916 to Zeebrügge, where it was found unsuitable, and it was shipped to Turkey on 21 Sep 1916.
- The WD.9 was derived from the WD.5. It served at Zeebrügge from May to June 1916 before being sent to Turkey in Sept. Nowarra hints that there may have been a small production order for use by Turkey.
- The WD.10 was a project only.. It was destroyed during testing in 1916.
- The WD.15 was a single-seat seaplane fighter that did not go into production.
- The WD.20 was a three-seat, twin engined long-range reconnaissance seaplane based on the WD.14. Only 1-3 were completed.
