Junkers Jumo 222
The Jumo 222 was a high-power aircraft engine design from Junkers, designed under the management of Ferdinand Brandner of the Junkers Motorenwerke. Such was the performance of the engine compared to contemporary designs that many developments of wartime Luftwaffe piston-engined aircraft designs were based around it, at least as an option. The design failed to mature even after years of intensive development, dooming the entire Bomber B program along with it. Only a small number were built, never leaving the prototype phase, but the design nevertheless continued appearing, endlessly, on proposals for new Luftwaffe multi-engined designs long after most had given up hope it would ever work.
