Schutte-Lanz D I
This type appeared in 1915, and apart from the absence of vertical fin and modified undercarriage chassis - note the unusual forward rake - the type appears to have been copied from the Sopwith Tabloid. Engine, 100 h.p. Gnome. Span, 7.5 m. (24 ft. 7 3/8 in.). Length, 5.4 m. (18 ft. 8 5/8 in.).

SCHUTTE-LANZ D I Germany
The Luftfahrzeugbau Schutte-Lanz produced, in 1915, what was subsequently claimed to be the first German single-seat biplane fighter. Designed by Dipl-Ing W Hillmann and Walter Stein, this, the D I, was a lightweight single-bay staggered biplane which had apparently found its inspiration in the Sopwith Tabloid. Of wooden construction throughout with fabric skinning, it was powered by an 80 hp Oberursel (Gnome) seven-cylinder rotary engine, but was rejected by the Idflieg on the grounds that the biplane afforded inferior pilot vision to the monoplane and was therefore unsuited for the single-seat fighter role. Hillmann and Stein introduced some redesign and installed a 100 hp Mercedes six-cylinder water-cooled engine to result in the D II, which, in the event, was never flown.

Schutte-Lanz D.I & D.II
In the summer of 1915 Schutte-Lanz produced a single prototype of a single-seat scout, the D.I. Designed by Dip. Ing. Wilhelm Hillmann and Walter Stein, the biplane that emerged was obviously influenced by the British Sopwith Tabloid. Powered by a seven-cylinder 80-hp Oberursel rotary engine, the machine was of conventional wooden construction with fabric covering and ply cockpit panels, and aluminium engine cowling. Wing warping was adopted for lateral control. It was unarmed. The aircraft underwent proof testing in February 1916. The pilot's field of vision was poor and Idflieg considered it unsuitable as a fighter compared with contemporary Eindeckers. A revised version with a 100-hp Mercedes six-cylinder in-line engine was proposed as the D.II, but never flew.
