The S-12 was a single seat mid-wing monoplane with wire-braced wings and powered by a Gnome Lambda air-cooled rotary engine rated at 80 hp (60 kW). It was smaller and lighter than the S-11 on which it was based, and was specifically designed to be highly maneuverable.[1][2]
The S-12 was the most successful monoplane Sikorsky designed during his time in Russia and twelve examples were produced. In September 1913 an S-12 became the first Russian aircraft to perform an inside loop at the Kolomyazhskiy hippodrome north of St. Petersburg. Later an S-12 set an altitude record of 3,680 metres (12,070 ft). During World War I and the Russian Revolution S-12s served with the Russian Air Force and some were still in service until 1922.
