The RBVZ S-XX was a Russian single-bay un-equal span two-seat biplane designed by Igor Sikorsky in 1916. Displaying some Nieuport influence, it saw very little service during World War I. Five S-XX aircraft were built in September 1916, with the first two powered by the 100 hp Gnome rotary engine which had powered its predecessor, the RBVZ S-XVI. However, the other three were powered with the 120 hp Le Rhone engine, with which they were allegedly faster than the French Nieuport 17.

Operational History

The S-XX saw little service due to it being viewed as inferior to newer enemy aircraft and no series production was undertaken. As such only 5 aircraft were ever produced.
