A U.S. Navy Martin XBM-1 (BuNo 9212) at the Langley Aeronautical Laboratory at Hampton, Virginia (USA). This aircraft, the Martin XBM-1, was built for the NACA and delivered through the Naval procurement system. This is an example of how well the NACA and the Navy worked together. The XBM-1 was used for various tests, including that of airfoil designs. This latter test used the airfoil section mounted between the wings on the right side of the aircraft.
