Sikorsky S-3 Sikorsky S-3 The Sikorsky S-3 was an early Russian single seat biplane design by Igor Sikorsky. Work on the machine started in July 1910 and was completed in late November. The S-3 was a larger improved version of the S-2 with a more powerful Anzani three-cylinder engine. The main wings were manufactured in a more uniform manner with the ribs held to a closer tolerance and the fabric covering was of better quality.
