The 7.5 cm Feldkanone 16 neuer Art (7.5 cm FK 16 nA) was a field gun used by Germany in World War II. Originally built as the World War I-era 7.7 cm FK 16, surviving guns in German service were re-barrelled during the early 1930s in the new standard 7.5 cm calibre. It was not modernized for motor towing and retained its original wooden spoked wheels and two crew seats on the face of the gun shield.

History

Over 3,000 FK 16 guns were made in 1916-1918 and they remained in use in the Interwar period's Reichswehr. In the 1930s its 7.7cm barrel was redesigned to become the standardised calibre of 7.5cm and the modified guns were named the '7.5cm FK nA' with 'nA' standing for 'neuer Art' or 'new pattern'. It was originally meant to be a horse-drawn cavalry support gun but it was later used with any type of formation in need of a light gun. One of these guns where tested in the Hillersleben test range in 1941 where it managed to achieve a maximum range of over , 30% more than its designed maximum.
