Sikorsky S.16

We continue with the very first operational Russian fighter in history.

Initially conceived as an escort fighter for the Sikorsky Ilya Muromets (just like the Olchovskij Torpedo ) it was designed by the person, Igor Sikorsky,  and was manufactured by RBVZ (which stands for Russko-Baltiiskii Vagonnyi Zavod - Russo-Baltic Wagon Works) .
Some early variants were two-seaters as they were intended for observation-scout duties. 

It was made out of wood and the fighter versions were equipped with a synchronising gear designed by the Russian engineer Lavrov, for the single 7,7mm forward-firing machine-gun. It was powered by a 100hp LeRhone engine and the first prototype was completed on 6th February 1915. On December of the same year the first production contract was placed on RBVZ. Although it was highly maneouvrable, it's performance was poor compared with another fighters of the same year, specially considering that it was seriously underpowered. 
The last production batch was completed in 1917, just before the revolution, and many S.16 fought through the Russian Civil war and at least one of them saw service under the Ukranian People's Republic. Some of them remained active until 1923. 
Another floatplane sub-variant was made, intended to serve with the navy, but it wasn't successful.

SPAD S.VII - Fourth entry, foreign users vol. 4 *UPDATED*

We keep going with our SPAD S.VII compilation, this time a little bit shorter than usual:

• Red Army/USSR: The Russian Red Army, employed them widely during the Russian civil war and Polish Soviet war and was among the very first fighters used by the Workers' and Peasants' Air Fleet (the precursor of the Soviet Air Force). They were ex-Imperial units or captured ones. 
• Siam/Thailand: The Thai king Rama VI, ordered the creation of an aviation division for the Siamese army, and the very first fighter squadrons were equipped with French built SPAD and Nieuport fighters. Please note that those two profiles are somewhat 'semi-speculative' as we only could find black & white references that were often unreadable.
• Ukraine: The Ukrainian People's Republic got two ex-Russian SPADs and used them in the Polish Soviet war. They were integral part of the Ukrainian first air regiment.
• Uruguay: The Uruguayan military school of aeronautics bought some S.VII together with some S.XIII and used them as trainers but they were also part of their first fighter squadron. However we couldn't find graphical evidence on this, so the colours must be considered as speculative.
• USA: Previously used by American pilots in the famous 124th squadron (Lafayette Squadron), the S.VII was among the very first airplanes used by the USAAS (United States Army Air Service), the precursor of the USAF.
• Yugoslavia: Ex-Serbian airplanes were used as trainers in the first flying schools of the Kingdom of Yugoslavia.

*UPDATE: We felt that the American users were... incomplete, that's why we decided to expand the USAS users and, in order to be consequent with our own criterions, we decided to treat the Lafayette Squadron as part of the French Aéronautique Militaire (as it was in reality) and therefore take them out of this drawing, only to replace them with more USAS airplanes, but don't worry because you can find the Lafayette squadron one's here..

**UPDATE: About the Spanish Pujol Comabella: In 1917 SPAD society granted to Pujol Comabella Society of Barcelona (which was shortly after absorved by the Hereter society) some blueprints and incomplete specifications of their best product, the S.VII fighter. The Pujol Comabella society started to make a replica of it as best as they could, getting a nice replica of the original and named as 'España'. However, given the quality of the employed materials or because the blueprints and specifications were incomplete, the performance was inferior to the original. 
That factor and the lack of need of a fighter, because up to that date the only role the Spanish Military had performed was to bomb and strafe Rifean positions in the Spanish protectorate in Morocco, made the project to fail given the lack of interest. 

Neither political scenario was favourable, it was in the middle of a great political crisis and at the edge of a revolution which was easily put-down by the army without any help from the aviation, which was highly concentrated in the protectorate of Morocco. 

It is interesting to point out how, the differences. It lacks windshield, the upper nose panel is lifted and the tail has two supporting wooden bars instead of just one, probably changes suggested by the engineer Eduardo Barron who was supervising the construction of the replica. Also it's interesting to see how on the presentation model, the characteristic bird of Georges Guynemer was copied. 

Only 12 of them were built and were declared obsolete and scrapped in 1922.
