The Junkers Jumo 004 was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. Some 8,000 units were manufactured by Junkers in Germany late in World War II, powering the Messerschmitt Me 262 fighter and the Arado Ar 234 reconnaissance/bomber, along with prototypes, including the Horten Ho 229.
The HeS 30 (HeS - Heinkel Strahltriebwerke) was an early jet engine, originally designed by Adolf Müller at Junkers, but eventually built and tested at Heinkel.It was possibly the best of the "Class I" engines, a class that included the more famous BMW 003 and Junkers Jumo 004.

The Junkers Ju 287 was a multi-engine tactical jet bomber built in Nazi Germany in 1944. It featured a novel forward-swept wing, and the first two prototypes (which were aerodynamic testbeds for the production Ju 287) were among the very few jet propelled aircraft ever built with fixed landing gear.

While the Daimler-Benz engine was mostly used in single-engined and twin-engined fighters, the Jumo engine was primarily used in bombers such as Junkers' own Ju 87 and Ju 88, and Heinkel's H-series examples of the Heinkel He 111 medium bomber. It was the most-produced German aero engine of the war, with almost 70,000 examples completed.
Initially, Junkers proposed modifications of the Jumo 004, specifically the 109-004G and 109-004H. However, these variants were rejected as they were not powerful enough, and Junkers began to design the 109-012. [1] The engine was to feature an 11-stage axial compressor enclosed in a sheet-steel casing and a 2-stage, air-cooled turbine.
E.g., the similar Westinghouse J30 (same type of engine, same type of age) has a thrust specific fuel consumption of 38 g/(kN⋅s) - which would make the Jumo 004 ten times more efficient. If Thrust-specific_fuel_consumption#Typical_values_of_SFC_for_thrust_engines is any guide, there's no such thing as a modern gas turbine working at anything ...
