The Bv 155 was an experimental high-altitude fighter developed by the Messerschmitt and Blohm und Voss companies toward the end of WWII. It never left the prototype stage. Only three prototypes were built.
The design was sound and flew well according to reports. Lack of funding and the end of the war prevented further work. The project significantly pushed forward the development of the turbo-supercharger.
