Linke-Hofmann-Busch (LHB)

Linke-Hofmann was a German manufacturing company originally established in Breslau to produce locomotives and . Its origins lay in the wheelwright business of Gottfried Linke, begun in 1834. It is now part of Alstom, the name Linke-Hofmann-Busch became defunct in 2009 when it became ALSTOM Transport Germany 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 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 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.
