Petersburg, was only partly concerned with aircraft production.
It was responsible, however, for
of the ll'ya Muromets series of four-engined bombers,
designed by Igor Sikorsky, which equipped Russia's
Eskadra Vozdushnykh Korablei (Squadron of Flying Ships)
in First World War. Largest of the series was the Type IMYe2,
with a wingspan of 34.50m and a gross
weight of 7,000kg. The Sikorsky S-16 reconnaissance
biplane was also built.
