Martin XA-15

Last revised July 1, 2000

In May of 1934, an attack version of the Martin YB-10 twin-engined bomber was proposed under the designation XA-15. It was to have had two 750 hp Wright R-1820-25 engines. Wingspan was to have been 70 feet 6 inches, and length was to have been 44 feet 8 inches. Gross weight was to have been 12,356 pounds, and maximum speed was estimated to be 214 mph at 4500 feet.

The design was dropped in favor of the faster Curtiss XA-14 before anything could be built.
