 | | The aircraft was still plagued by reliability problems of its powerplants; however, while the Junkers Jumo 004 engines were of the advanced axial-flow design, they suffered from a lack of high-quality strategic materials required during the manufacturing process, a result of the Allied bombing offensive and the turn of war fortunes for Germany. |
 | | The Me 262 was soon joined by other highly advanced aircraft designs, such as the Arado Ar 234 twin- and four-engine jet bomber/reconnaissance aircraft, the Heinkel He 162 single-engine jet fighter (powered by a BMW jet engine), the Messerschmitt Me 163 rocket fighter and others. |
