The Siemens-Schuckert R.IV was a bomber aircraft built in Germany during World War I. It was one of six aircraft based on the Siemens-Schuckert R.I that were originally intended to be identical but which each developed in a different direction and were designated as different aircraft types by the German Inspectorate of Flying Troops (the Idflieg).
