The Goliath was initially designed in 1918 as a heavy bomber capable of carrying 1000 kg of bombs with a range of 1500 km. It was a conventional fixed-undercarriage biplane of wooden construction with canvas covering, powered by two Salmson Z.9 engines. It had a simple and robust, yet light structure. The wings were rectangular with a constant profile. Hollow wooden main wing spars were used for the first time.
