Linke-Hofmann of Breslau was a railroad firm, but starting in 1916 they built licensed-copies of L.F.G. Roland and Albatros designs. They experimented with a couple of giant bombers in 1917-1919, but neither came to fruition.
Prototype aircraft from the Great War or shortly thereafter include:
- The R.I (R.8/15) four-engine tall-fuselage design that was tested from Jan 1917 until it crashed on 10 May 1917. Three more were planned, with R.40/16 reaching testing and R.41 and R.42 partial completion.
- The R.II was a four-engine bomber that looked like an enormously-upscaled two-seater, with all four engines driving a single forward propeller. It is thought to have been the largest single-propeller plane ever built. R.55 flew in January 1919 but was soon abandoned. R.56 was almost completed but never flew.
