The S.E.A.4 was ordered in large numbers, but the first production example was not completed until Armistice Day 1918.

The design of the Dr I was inspired by the Sopwith triplane that made its debut at the Front in the spring of 1917.

Of innovative configuration, the D VI carried auxiliary lifting surfaces on the parallel main wing bracing struts.

The D VII was still under flight test at the time of the Armistice in 1918, having first flown five months earlier.

One of the first German fighter biplanes, the Otto Schwade-designed aircraft (shown) was flown in 1914, being abandoned in favour of the somewhat more sophisticated second Schwade fighter design.
