History
Igor Sikorsky designed a series of progressively refined biplanes in Russia from 1910 onwards, and the S-11 of 1913 was part of this sequence. Built at the Russo-Baltic Wagon Factory's aviation department, it provided Sikorsky with valuable experience that fed into his later large multi-engine designs. The S-11 was used for training and sport flying.
