O.Thetford, P.Gray German Aircraft of the First World War (Putnam)
The two aircraft illustrated are the only known wartime products of the Schwade Flugzeug und Motorenbau of Erfurt. Unfortunately no data is available, although it is obvious they were extremely diminutive machines with a span roughly between 6 and 7 m. (19 ft. 8 1/4 in. to 22 ft. 11 5/8 in.). The earlier machine had tubular outriggers supporting the tail, and the second machine what appears to be ply-covered booms. A single-seat triplane was also built, but no photograph has been traced. Engine, 80 h.p. Oberursel (1914 machine), 110 h.p. Oberursel (1916 machine).

SCHWADE KAMPFEINSITZER Nr 1 Germany
In 1914, the Otto Schwade concern of Erfurt initiated the flight test of a small single-seater powered by an 80 hp Schwade Stahlherz seven-cylinder rotary engine installed as a pusher behind an abbreviated circular section nacelle. A single-bay biplane with tubular outriggers supporting the tail surfaces, the Schwade single-seater, known as the Nr 1, was fitted with a Bergmann LMG 15 7,9-mm machine gun on a flexible mounting during the course of flight trials, but no details of these are recorded and development is believed to have been abandoned at an early stage in favour of a more advanced design, the Nr 2.
SCHWADE KAMPFEINSITZER NR 2 Germany
Late in 1915, Otto Schwade produced a single-seat two-bay biplane twin-boom pusher fighter, the Nr 2, which appears to have been developed in the light of experience gained with the company's first Kampfeinsitzer. A somewhat ungainly aircraft with the pilot accommodated in a circular-section nacelle suspended between the wings by a profusion of struts, and twin vertical tail surfaces carried by ply-covered booms of narrow oval section, this aircraft was powered by a Schwade Stahlherz seven-cylinder rotary engine of 80 hp. No further details of this aircraft have been recorded.
