About: Siemens-Schuckert R.IV

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). The Maybach HS engines specified by the Idflieg proved unreliable, but with these engines were replaced by Benz Bz.IV engines, the R.IV saw service on the Eastern Front before being relegated to training duties.
