In 1938, the Glenn L. Martin Company developed the Model 167 as a response to the requirement of the United States Army Air Corps for a light bomber. It was designated as XA-22, however, it was not approved for operational use in the United States. Subsequently, the aircraft acquired foreign orders and after some time, led to the designation Maryland MK I.

The Maryland MK I had three crew members: a pilot, a navigator/ bomb aimer/ gunner, and a radio operator/ gunner. The aircraft has an exterior length of 14. meters, an exterior height of 3.1 meters, a tail height of 5 meters, and a fuselage diameter of 1.2 meters. The wings have a wingspan of 18.7 meters and a wing area of 49.9 square meters. The wheelbase is 9.3 meters.

The MK I was fitted with two Pratt and Whitney R-1830-S1C3-G Twin Wasp radial engines. It was a fourteen-cylinder two-row supercharged radial with two overhead valves per cylinder, a single-speed General Electric centrifugal-type supercharger, two-barrel Stromberg carburetor fuel system, air-cooling system, and an epicycling reduction gear. The engine produces a maximum power of 1,050 hp each and drives three-bladed Hamilton Standard 3T50 constant-speed metal propellers. The aircraft has an empty weight of 4,802 kg and a gross weight of 6,939 kg. The maximum takeoff weight is 7,624 kg, the maximum payload is 1100 kg, and the fuel tank capacity is 617 US gallons.

The American-designed light bomber has a maximum speed of 264 knots at 13,000 feet and a cruise speed of 216 knots. It has a travel range of 1,100 nautical miles and could fly up to 29,500 feet. The rate of climb is 2,400 feet per minute. The Maryland MK I could be loaded with four 7.7 mm Browning MK II medium machine guns attached in outer wings with 750 rpg, a single 7.7 mm Vickers K rapid-firing machine gun in dorsal and in ventral. The dorsal gun was attached in an entirely-retractable turret. It could also be loaded with 907 kg of internal bombs.
