The first Danish fighter aircraft to be conceived and built, the singe seat Type AA was of wooden construction and powered by a 90 hp Thulin rotary engine. It was armed with two guns.

The first flight took place on 21 January 1917. The plane was tested again in 1918, this time with synchronising gear for its single Madsen machine gun. During 1917 six Type AA aircraft were delivered to the Danish Army, though they saw little service and were retired in 1919 owing to engine unreliability.
