The Siemens-Schuckert Werke S.S.W. E II was a variant on the earlier S.S.W. E I monoplane scout, but using an Argus inline engine in place of the Siemens rotary engine of the E I. The E I was a shoulder-winged monoplane, with wing warping controls and a rather high undercarriage. It was powered by an unusual Siemens rotary engine, and one batch of twenty aircraft was produced.
The E II was a very similar shoulder winged monoplane, although pictures do suggest that the undercarriage was lower. The Siemens rotary engine was replaced with a 120hp Argus As II inline engine, but the two aircraft were otherwise very similar.
A single prototype E II was completed early in 1916. The aircraft crashed during a demonstration at Döberitz in June 1916. At the time it was being flown by its designer, Franz Steffen, and he was killed in the crash.
Engine: Argus As II
Armament: One Spandau machine gun
