The XA-1 was designed as an ambulance aircraft to replace modified de Havilland DH.4 aircraft with the United States Army Air Service. The XA-1 was a biplane powered by a 420 hp (313 kW) Liberty 12A engine with a fixed conventional landing gear, it had a crew of two and room for two stretchers. Two prototype aircraft designated XA-1 (A-1 was the first allocation in the army air services ambulance designation system) were flown but no further aircraft were built.
In April 1927 after a tornado struck the town of Rocksprings Texas, the Army sent eighteen DH-4 observation planes, two Douglas transports, and a Cox Klemin, who flew in supplies and physicians, to treat 200 injured citizens.
Some of the more seriously injured being flown out by the XA-1 to San Antonio.
