Boeing YB-9 Bomber

Boeing YB-9 airplane model. The YB-9 was originally owned, developed and tested by Boeing as the XB-901 (NX10633). The plane was based on the Model 200 commercial transport but was enlarged and adapted to the bomber role. The YB-9 was powered by two Pratt & Whitney R-1860 radial engines which gave it a top speed of 163 mph. Later in its service life, the YB-9 was fitted with the same engines powering the Y1B-9A service test aircraft bringing its top speed to 188 mph; as fast as the U.S. Army pursuit planes of the time.

A total of seven aircraft were built: the prototype YB-9, a liquid-cooled engine Y1B-9, and five service test Y1B-9As. The aircraft never entered production mainly because there were even better aircraft being designed which would change the course of U.S. bomber development.
