"The Heinkel He 277 was a four-engine, long-range heavy bomber design, originating as a derivative of the He 177, intended for production and use by the German Luftwaffe during World War II. The main difference was in its engines. While the He 177 used four engines in two coupled pairs which proved troublesome, the He 277 was intended to use four unitized BMW 801E 14-cylinder radial engines, in single nacelle installations. The design was never produced and no prototype airframe was completed.[1] The deteriorating condition of the German aviation industry late in the war and the competition from other long-range bomber designs from other firms, led to the design being cancelled." - Wikipedia; Heinkel He 277
