The Sikorsky S-15 was a single engine light bomber floatplane built in 1913 at the Russian Baltic Railroad Car Works while Igor Sikorsky was the chief engineer of the aircraft manufacturing division. Similar in design to the Sikorsky S-10, only one example of this biplane was produced.^[1]^[2]

A floatplane is a type of seaplane, with one or more slender pontoons mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats.

Russo-Balt was one of the first Russian companies that produced vehicles and aircraft between 1909 and 1923.

Igor Ivanovich Sikorsky, was a Russian-American aviation pioneer in both helicopters and fixed-wing aircraft. His first success came with the S-2, the second aircraft of his design and construction. His fifth airplane, the S-5, won him national recognition as well as F.A.I. license number 64. His S-6-A received the highest award at the 1912 Moscow Aviation Exhibition, and in the fall of that year the aircraft won for its young designer, builder and pilot first prize in the military competition at Saint Petersburg.

The Sikorsky S-37 was an American twin-engine aircraft built by the Sikorsky Manufacturing Corporation. Both examples of the series were completed in 1927. The S-37 was specifically designed to compete for the Orteig Prize and would be the last land based fixed-wing aircraft Sikorsky would produce.

The Sikorsky S-19 was a Russian twin engine experimental prototype biplane aircraft built late in 1916 by the Russian Baltic Railroad Car Works while Igor Sikorsky was chief engineer of the aircraft manufacturing division.

The Sikorsky S-2 was the second fixed wing aircraft designed by Igor Sikorsky using the main wing section from the S-1 and a 25 hp (19 kW) Anzani 3 three-cylinder engine in a tractor configuration. During the first flight attempt on June 3, 1910 the biplane reached a height of two to four feet and traveled approximately 200 yards. After several successful flights the S-2 was completely destroyed on June 30 when Sikorsky inadvertently stalled the underpowered aircraft at an altitude of 70 feet.

The Sikorsky S-33 Messenger was an American two-seat sesqiuplane designed and built by the Sikorsky Manufacturing Corporation in 1925.

The Sikorsky S-1 was the first fixed wing aircraft design by Igor Sikorsky. In February 1910 work began on the pusher configured biplane powered by a 15 hp (11 kW) Anzani three-cylinder, air-cooled engine. The machine was completed in April and Sikorsky began his first attempts at flight. In early May during a take-off attempt on a windy day the machine briefly became airborne due mostly to the fact it had a favorable headwind. Further attempts were less successful and Sikorsky disassembled it, saving the main wing section to construct the S-2.

The Sikorsky S-4 was a Russian aircraft built by Igor Sikorsky using many components of the S-3 including the 40 hp (30 kW) Anzani three-cylinder engine. Construction of the biplane began in late December 1910 and was completed early in the spring of 1911. The machine was never flown but did appear in a static display at an aeronautical exhibition at Kharkov in the spring of 1911. Sometime afterward it was disassembled.

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 Sikorsky S-30 was a proposed aircraft design by Igor Sikorsky to be built by the Sikorsky Manufacturing Corporation at Roosevelt, New York in 1925. The twin engine biplane was to have been used on mail routes or configured as a commercial passenger airliner. No examples of the S-30 were ever manufactured.
