Marlin-Rockwell Corporation of Philadelphia, Pennsylvania was awarded a contract by the US Army Air Service, American Expeditionary Force (AEF) in June 1917 to produce 5,000 Barlow-type aerial bombs. The order was increased to 28,000 by April 1918 before being canceled in June 1918 after 9,000 were produced due to production delays because of modifications needed with the firing mechanism. The company was also awarded a contract to produce Mark II type demolition bombs in December 1917 and produced more than 36,000 by November 1918. The company also produced a large number of aircraft machine guns under various contracts for the US Army Air Service during World War I.
