The Nielsen & Winther Type AA, also known as the Type Aa, was a Danish fighter aircraft of the 1910s.

Development

The first Danish fighter aircraft to be conceived and built, the Type AA was of wooden construction, and with a single seat. Armed with two guns and a 90 hp Thulin engine (thanks to a sizeable amount of design help from AB Thulinverken).

Operational history

The first flight took place on 21 January 1917, and 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, however these saw little service and were retired in 1919 due to engine unreliability.
