With the S-5, Igor Sikorsky's fortunes began to change. Completed in late April 1911, with a 50hp Argus water-cooled engine, it was tested in a series of 20 to 30-second straight-line flights over a period of three weeks before the young designer was able to make what he called his first real flight of four minutes, in a circuit of the field, on 17 May.

The Sikorsky S-10 was a Russian military twin-float seaplane built by the RBVZ that served with the Baltic Fleet from the summer of 1913 to 1915. After Igor

Sikorsky built the successful Sikorsky S-6 for the Russian military, he tried to build another successful aircraft for them. The S-10 was a modified S-6B built by the Russo-Baltic Carriage Factory. Approximately sixteen production versions of the S-10 were built. It had a less powerful engine and generally weaker structure than the S-6. They had either a 80 HP Gnome Monosoupape or a 100 HP Argus Motoren engine. Some were deployed on the world's first operational seaplane carriers.

Sikorsky's Ilya Mourometz was the world's first four-engine bomber. Construction started in August, 1913 and first flight was in January, 1914. The cockpit had space for several persons. Openings on both sides of the fuselage permitted mechanics to climb out on the wings to service the engines during flight. A hatch on the left side provided an exit to the front bridge. Behind the cockpit was a large passenger cabin. In the rear was a stairway to the upper bridge and a washroom. Further back was a private cabin including a berth, small table and cabinet. During World War I over 75 ILia Mourometz were deployed in a special squadron at the front for bombing and reconnaissance missions.

The Ilya Muromets (Sikorsky S-22) was designed and constructed by Igor Sikorsky at the Russo-Baltic Carriage Factory (RBVZ) in Riga in 1913. It was based on his earlier S-21 Russky Vityaz or Le Grand which had played an important role in the development of Russian aviation and the multi-engine aircraft industries of the world.

Russia had a chance to become the birthplace of the first multi-passenger and multi-engine airliner. The Ilya Muromets was first conceived and built as a luxurious aircraft. For the first time in aviation history, it had an insulated passenger saloon, comfortable wicker chairs, a bedroom, a lounge and even the first airborne toilet. The aircraft also had heating and electrical lighting.

On 10 December 1913, the Ilya Muromets was tested in the air for the first time, and on 25 February 1914, took off for its first demonstration flight with 16 passengers aboard. From 21 to 23 June (one source gives 30 June - 12 July interval), it set a world record by making a trip from St Petersburg to Kiev, a distance of some 1200 km, and back. The first leg took 14 hours and 38 minutes with one landing for fuel - at Orsha, and the return one, with a fuel stop at Novosokolniki, took even less time, some 13 hours. If it had not been for World War I, the Ilya Muromets would probably have started passenger flights that same year.

Sikorsky S-16

The Sikorsky S-16 (named after its designer) or RBVZ S-XVI (named after its manufacturer) was a Russian equi-span single-bay two-seat biplane designed by Igor Sikorsky in 1914-15. Conceived in response to demand for an escort fighter for the Ilya Muromets bombers. The prototype S-16 made its first flight on February 6, 1915. This prototype was fitted with an 80 hp air-cooled 7 cylinder, Gnome rotary engine instead of the intended 100hp because of supply problems. The S-16 was the first Sikorsky fighter to be equipped with a synchronized machine gun firing through the propeller. However, the synchronization left much to be desired. The S-16, with slight modifications from batch to batch survived the Revolution and were operational with the Red Air Force through the Civil War.

The Sikorsky S-20 (named after its designer) or RBVZ S-XX (named after its manufacturer) was a Russian single-bay un-equal span two-seat biplane designed by Igor Sikorsky in 1916. Displaying some Nieuport influence, it saw very little service during World War I. Five S-XX aircraft were built in September 1916, with the first two powered by the 100 hp Gnome rotary engine which had powered its predecessor, the RBVZ S-XVI. However, the other three were powered with the 120 hp Le Rhðne engine, with which they were allegedly faster than the French Nieuport 17.

The S-XX saw little service due to it being viewed as inferior to newer enemy aircraft and no series production was undertaken. As such only 5 aircraft were ever produced.
