The Anatra DS was an improved version of the Anatra D and had a more powerful Salmson engine. The plane was called "Anasal," short for "Anatra Salmson." The Salmson engine was one of the few water cooled rotary engines used in the First World War.
The Anatra DS was a two seat reconnaissance aircraft with a ring mounted gun in the rear cockpit for the observer and a fixed synchronized machine gun for the pilot. Improvements were made after initial tests, making the Anasal a stable aircraft with good speed and responsive flying characteristics.
The Anatra DS was used throughout Russia's participation in World War I, and by both sides during the revolution.
