The S-15 was a seaplane of the S-10 family.

The S-12 was built at the suggestion of George Yankovsky as a lighter, single-seat version of the S-11 with an 80hp Gnome. He looped it in September 1913, the first time a Russian aircraft had performed this manoeuvre, and set a Russian height record of 3680m shortly afterwards. Most of the dozen or so S-11s that were built survived the war, and served in the earliest Soviet Air Force units during the Revolution. Several were still operational in 1922, mostly with an 80hp Le Rhone engine.
Russo-Baltic Waggon Works Sikorsky S-11 Pulukrugliy
Developed from the larger and heavier S-9, the 1913 S-11 Polukroogly (half-round) had a conventional wooden fuselage and 100hp Gnome Monosoupape engine. It was initially equipped with ailerons that were operated by steel tubes inside the wing. Trials revealed that they were not efficient, so they were replaced by wing warping. The pilot and observer sat side-by-side, with controls only for the left seat. A top speed of 100km/h, stalling speed of 70km/h and take-off run of 75m were good enough to gain the S-11 second place in the 1913 military competition for a reconnaissance aircraft; but it was not ordered into production.

Russo-Baltic Waggon Works Sikorsky S-6 / S-10
Constructed in Kiev, this 100 hp Argus-powered biplane was used by Igor Sikorsky to set new Russian flight records in November 1911, even setting a world-record with his design – a distance record with two passengers.
Under the designation S-10, about sixteen production versions of the S-6B were built by the RBVZ. The majority were delivered as twin-float seaplanes for service with the Baltic Fleet, from the summer of 1913 to 1915, with 100hp Argus or Gnome Monosoupape engines. Some were deployed on the world’s first operational seaplane carriers.
A special Competition S-10 landplane, with 80hp Gnome engine, was built for the 1913 military aircraft competition. The wing span was increased to 16.75m, with outer panels that could be folded for storage. The two seats were placed side-by-side, and the control wheel could be swung from pilot to co-pilot during flight. Production test pilot Alechnovich set a Russian record by flying it 500km in 4 hours 56 minutes, and it took first prize in the 1913 competition although it lacked the speed and manoeuvrability of the S-6B. After its span had been reduced to 13.70m and a 100hp Monosoupape installed, it served as a trainer with the Baltic Fleet.
The S-10A’s span of 13.7m and two seats in tandem set the standard for all S-10 seaplanes, and its 125hp (de-rated to l00hp) Anzani engine gave it better speed and rate of climb than the Competition S-10. Its flying characteristics were less good, preventing it from gaining first prize, but it set a new Russian height record of 3420m, piloted by Gleb Alechnovich. Modified to have a 100hp Monosoupape and floats, it was assigned to the Baltic Fleet.

Russian Empire airship B-2 USSR Smolny
By May 1932, the Russian Empire had built three airship — the USSR B-1, B-2 USSR “Smolny” and the Soviet B-3 “Red Star”, which in the main have been set up to implement educational and propaganda operations. The B-1 envelope was 2200 cubic meters and B-2 5000 cubic meters. The airships had different engines. The V-2 had two 230 hp engines and could carry 8 passengers. The envelope of all 3 airships was made of three-layer rubberized material and had an inner wall that divided the volume of the two equal parts. This partition to reduced transfusion of gas along the envelope for trim of the craft.
These three airships performed a series of successful flights on the routes of Leningrad — Moscow — Leningrad, Moscow — Kharkov, etc. The three airship were joined by USSR-4.
On September 6, 1935 USSR-2 Smolny was at the Stalino (Donbass) airport, when wind pulled out of the ground all 60 anchors that held it. Have seized on one of the cables commander of dirigible NS Gudovantsev managed at an altitude of 120 meters to get to the gondola, in which at that time were 4 crew members and 11 tourists. At an altitude of 800 meters the engines were running. After that, having waited for the adverse weather conditions to decrease, the airship landed safely after 5 hours and 45 minutes. For this heroic act Gudovantsev was awarded the Order of the Red Star.
The airship crashed in the Novgorod Region in 1933 when its engines failed.
The airship was disassembled in 1939.
Russian Empire airship USSR B-1
By May 1932, the Russian Empire had built three airship — the USSR B-1, B-2 USSR “Smolny” and the Soviet B-3 “Red Star”, which in the main have been set up to implement educational and propaganda operations. The B-1 envelope was 2200 cubic meters / 78,000 cu ft and B-2 5000 cubic meters. The V-1 was designed to pick up passengers without landing. The airships had different engines. The envelope of all 3 airships was made of three-layer rubberized material and had an inner wall that divided the volume of the two equal parts. This partition to reduced transfusion of gas along the envelope for trim of the craft.
These three airships performed a series of successful flights on the routes of Leningrad — Moscow — Leningrad, Moscow — Kharkov, etc. The three airship were joined by USSR-4.
During The Second World war SSSR-V1 was used for carrying supplies for captive balloon units of Red Army, making more than 900 flights.
