Douglas XB-22

Last revised August 1, 1999

It was readily apparent by the late 1930s that the performance of the B-18 bomber was rapidly rendering it obsolete. In an attempt to improve the performance of the B-18A, Douglas proposed that 1600 hp Wright R-2600-1 radials be fitted to a version of the B-18A to be designated XB-22. In spite of the substantial increase in power offered by the larger engines, the performance of the XB-22 still fell short of requirements and the project was abandoned before anything could be built.
