On 17 January 1918 Glenn L Martin received a US Army contract to design and produce ten examples of a twin-engined, four seat reconnaissance bomber. In the absence of any military lead, the aircraft was called the GMB, short for Glenn Martin Bomber and came together fairly quickly under the supervision of Martin's Young Chief Engineer, Donald W Douglas. First flown on 15 August 1918, the GMB was powered by two 400hp Liberty 12As that gave the biplane atop level speed of 101.5mph at sea level, dropping to 100mph at 6,500 feet. Armed with five .30-inch Marlin machine guns, the GMB could lift a 1.040lb bomb load over a range of 390 miles at a cruising speed of 92mph. With the first aircraft delivered to the US Army in October 1918, the company had delivered all but one by the time of the Armistice, the tenth machine being completed in 1919 as a passenger transport.
