High Quality Content by WIKIPEDIA articles! The Jumo 004 was the world`s first turbojet engine in production and operational use, and the first successful axial compressor jet engine ever built. Some 8,000 units were manufactured by Junkers in Germany during late World War II and powered the operational Messerschmitt Me 262 jet fighter, Arado Ar 234 jet reconnaissance / bomber, and prototypes of the Horten Ho 229 aircraft. Variants of the engine were produced in Eastern Europe in the years following the war.
