Martin XB-14

Last revised July 17, 1999

The Martin XB-14 (33-162) was a version of the YB-10 powered by a pair of 950hp Pratt & Whitney YR-1830-9 Twin Wasps. It was common in those days to assign a separate model number to aircraft which differed from each other only in the type of engine which powered them. Only one example of this version was built.
