Junkers Jumo
Junkers also ran an engine factory, and in 1923 they separated it from the parent to form its own company, Junkers Motoren, or Jumo. This company expanded greatly in the 1920s and 30s, with factories spread across Germany. Jumo was the first German company to offer a truly modern engine suitable for aviation in the form of the 650 hp Jumo 210. But with the rapid advances in airframes, after a few short years this engine was considered to be underpowered, causing Jumo to respond with the much larger Jumo 211. Perhaps unsurprisingly, the 211 saw widespread use in Junkers bombers but was little used otherwise, due largely to the better power output of the competing Daimler-Benz DB 601. Further development of the 211 led to the superb Jumo 213, which was in high demand for practically every late-war piston-engined aircraft. The Jumo 004 jet engine was the first to be considered production quality, and was used in the then revolutionary Messerschmitt Me 262 jet fighter.
