In the late 1930s Douglas developed the B-18 to replace the Martin B-10 as the US Army Air Corps' standard bomber, but by 1942 superior designs such as Boeing's B-17 had supplanted it, many being relegated to transport or anti-submarine work. This example was redesignated as an RB-18A in 1942 and after being used for utility duties, was operated post-war as a crop duster registered N56847. It was ferried to the USAFM in 1971
