Alstom Transport Deutschland, formerly Linke-Hofmann-Busch, is a German manufacturing company originally established in Breslau (now Wrocław, Poland) to produce locomotives and rolling stock. Its origins lay in the wheelwright business of Gottfried Linke, begun in 1834. After World War II, the company was reestablished in Salzgitter in West Germany. In 1994, GEC Alsthom acquired a 51% shareholding.^[1] It is now part of Alstom; the name Linke-Hofmann-Busch ceased to be used in 2009 when it became Alstom Transport Deutschland GmbH.

During World War I, it became one of many companies in Germany drawn into the aircraft industry even though they had no prior experience in aircraft design.

Linke-Hofmann-Busch first entered the aircraft industry by repairing and constructing aircraft designed by other established companies under licence, such as the Roland C.IIa, Albatros B.IIa, C.III and C.X. In 1916 Linke-Hofmann-Busch was awarded a contract to design and build a four-engined heavy bomber under the Riesenflugzeug ("giant aircraft") designation. Two designs were built in prototype form, the R.I and the R.II; both designs were unconventional. The R.I was unsuccessful, but the Linke-Hofmann R.II flew well. However, the war ended before it could go into production. Post-war attempts to build R.II's as passenger and transport aircraft were prevented by the Allied Control Commission which was concerned about bombers being built illicitly, under the guise of airliners, and the possible resumption of the war.
