Martin 167 Maryland/187 Baltimore

Aircraft Lists

In the late 1930s the Glenn L. MArtin Company created the Maryland for the US Army (later selling it to France) and the Baltimore for Britain's RAF. Both were twin-engined light bombers with a modest bombload, defensive armament and performance that compared poorly with modern fighters like the Supermarine Spitfire and the Messerschmitt Bf 109. Although they were solidly designed aircraft, they were not advanced enough for World War II.

The Maryland was designed by Martin engineer James S.McDonnell, who later gave his name to the McDonnell Douglas Corporation. It was tested by the US Army as the XA-22 and performed better than attack bombers put forward by other manufacturers. The Army withheld a production contract, however, and the Maryland was exported instead to France. The first Marylands left the factory on 2 September 1939, the day before France and Britain declared war on Germany. They had little impact on the conflict, however.

The Maryland led to the Baltimore, which was known by the US Army as the A-30. Built to satisfy British requirments, the Baltimore was a somewhat more formidable attack bomber that was used extensively in North African fighting at El Alamein in June 1942. The Baltimore also achieved moderate success in Italy later in the war.

The last Baltimores served with the RAF in Kenya, performing aerial mapping and locust control duties until 1948.
