Martin 146

The Martin Model 146 was an American bomber that the Glenn L. Martin Company built to compete in the Army Air Corps design competition of 1934 and 1935, against the Boeing Model 299 that became the B-17 and the Douglas DB-1 that became the B-18. It closely resembled the earlier Martin B-10 and used two Wright R-1820 Cyclone engines, but it had a wider fuselage that let pilot and co-pilot sit side by side and it was the first large aircraft fitted with Fowler flaps. The Douglas design won, the aircraft was returned to the factory and scrapped, and the work fed later Martin studies including the Model 179 that became the B-26.
