The Rolls-Royce/MAN Turbo RB.153 was a high-performance 6,850 pounds-force (3,110 kgf) dry thrust turbofan engine developed jointly by Rolls-Royce Limited and MAN Turbo. Developed for the German EWR VJ 101D interceptor with a German-developed thrust-deflector system and first run in January 1963. The engine was also proposed for a number of other military VTOL projects including the Hawker P.1157. A commercial-version of the engine was also considered for the Messerschmitt Me P.160 airliner. The VJ101D project was cancelled and the engine never flew, being retained as a test bed.
