The AEG DJ.I was a highly streamlined biplane ground attack aircraft of late World War I that was undergoing evaluation at the time of the Armistice.
[1] The single seat attack biplane, which began evaluation in September 1918, carried a pair of 7.92 mm (.312 in) "Spandau"-type machine guns and a light bomb load.
The design featured aluminium fuselage coverings, I-type interplane struts with no flying or landing wires, and protective armour.
