Nieuport 11 & 16, part four. The 'Bébé' in service with Russia and the USSR.

 

During World War I, the Imperial Russian Air Service (IRAS) found that the Nieuport 10 (a versatile sesquiplane, forerunner of the Nieuport 11 which could fill a wide variety of roles, among them, the fighter one) was barely effective as a fighter and saw the Nieuport 11 as an important improvement. Initially, some few French machines were imported but a license production contract was granted soon to Dux factory, in Moscow. 
An early order of 200 Nieuport 11s was soon placed with Dux in 1916. Dux-built machines differed from the original French machines. For instance, Russian-built machines were made out of pine, instead of spruce and flax was employed for covering in lieu of silk, due to the scarcity of materials in Tsarist Russia. Those changes in construction materials made the Dux-Nieuport 11s to be 30 kg heavier than its French counterparts and their quality overall was very poor. Quoting a commander of the 8th Fighter Unit, the Dux Nieuports "... could not be assembled because the parts did not fit and... the bolts fixing the struts with the spars broke into pieces." The 'Bébé' was later built under license by Mosca-Bystritsky (Moscow), Anatra (Odessa) and Shchetinin (St. Petersburg), making a total of just seventy machines being manufactured in 1916.
The initial imported Nieuport 11s were unarmed, so many pilots of the front-line squadrons had to supply their own weapons, like pistols and rifles. Luckily for them, V.V. Jordan designed a machine gun mount that allowed a weapon to be carried, although it had to be angled in order to fire over the propeller, the mount enable it rotate vertically. 
The Nieuport 16, on the other hand, was mainly imported to Russia with some few examples being built by Dux. The purchased Nieuport 16s were powered by the 110 hp. Le Rhône 9J engine with one Nieuport 16 being powered by a de-rated 80 hp Le Rhône, which was employed as a trainer.

Anyway, both Nieuport 11 and Nieuport 16s were supplied to frontline squadrons and by 1st March 1917 there were ten serving in the northern front, five serving in the western front, sixteen in the south-western front, five in the Romanian front and one in the Caucasus front, making a total of 37 machines.
One month later, there were a total of 70 Nieuport 11s in active service and by June 1917 there were twelve at the northern front, four at the western front, twenty-five at the southwestern/Romanian fronts and seven at the Caucasus front.
The Nieuport 11 proved to be a huge improvement, specially when compared to the Nieuport 10, however, it was soon replaced by the Nieuport 17, when it became available. 
The Nieuport 11 was employed also during the subsequent Russian Civil War, by both Bolsheviks and Whites, mainly as trainers. In fact, when the Civil War was almost over, in December 1921, there were a total of 18 Nieuport 11 in service as trainers serving with the 2nd Military School of Pilots and the 1st Higher School of Military Pilots in June 1923, with the last one being written off charge in 1924.

Avro 504K European Users, part two

Now's the time for the second part of the European users of the Avro 504K.

• Ireland: The Irish Air Corps had six of them from 1922 until 1932. Further details are unknown.
• Latvia: The Latvian air force adquired two Avro 504K in 1924 and 1925 which were active until 1930 when they were replaced by the German Udet U.12 Flamingo.
• Norway: The Norwegian Army Air Service used some 504K apparently during the 1920 with a modified engine. Further details are, unknown.
• Poland: The Polish Air Force had one in inventory during the 1920s. 
• Russian Republic (Whites): Apparently one was used by the Slavonic-British Air Corps during the Northern Campaign of the Russian Civil War. Interestingly enough, it was used in the recon role, hence the observer machine-gun, instead in the training role.

Mosca Bystritskii

Today we bring you another not very known Russian world war I fighter.

The Mosca Bystritskii was a Russian fighter/recon airplane designed and developed during 1916 by the Muscovite company Mosca-Bystristkii.

Inspired by some contemporary airplanes like the Nieuport IV or the Morane-Saulnier G, the prototype and earliest versions, were unarmed and were two-seaters intended to perform recon duties and the fighter versions (the bis ones) were faster due to the fact that they weren't two-seaters. It was powered by an 80hp LeRhone engine or Clerget Rotary engine. The bis version was armed with either a 7,7mm unsynchronised forward-firing machine-gun with a bullet defector mounted in the propeller or, alternatively, with the machine-gun mounted above the cockpit and firing clear from the propeller. In total, 50 exemplars of it were manufactured and it's known that some of them were built after the Russian revolution.

A very interesting feature of this airplane were the backwards folding wings to make the airplane easier to transport by road or by train.

As we said previously, only two versions were made:

• Bystritskii: Two-seater unarmed recon version.
• Bystritskii bis: Single-seater fighter version.

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 - Third entry, foreign users vol. 3

We continue with our SPAD S.VII saga, this time with even more foreign users of the SPAD S.VII, this entry is a continuation of this other one:

• Poland: One of the main post-war users of the SPAD S.VII and one of the very first airplanes that constituted the Wojska Lotnicze (Polish Air Force) back in 1918. It saw action during the Polish Soviet war.
• Portugal: It made famous in this country because the Portuguese ace Oscar Monteir Torres, the only Portuguese pilot who died in aerial-combat during the great war, flew one of these. When the Portuguese Aviation Corps was founded back in February 1919, the fighter squadron was equipped with S.VIIs. This same squadron was renamed in December 1921 as 'Captain Monteiro Torres Squadron'.
• Romania: Apparently some S.VII were employed during the great war by the Romanian Royal Aeronautics. As we couldn't find graphic evidence, the colours are speculative.
• Imperial Russia: The Imperial Russian Air Service employed them widely in the eastern front of the great war and it was also used by the Whites during the Russian Civil War. It's also worth mentioning that the three versions of this airplane were employed: The ones made by SPAD themselves, the ones made by Blériot and the ones made locally by DUX in Moscow.
• Serbia: Some Serbian pilots, integrated in the French SPA.523  squadron, flew S.VII airplanes which later, after the war would form the very first fighter units of the kingdom of Croats Slovenes and Serbs, or, as was commonly known, Kingdom of Yugoslavia (those will be covered in the next entry). During the great war they were used in the Macedonian (Thessaloniki) Front
• 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.

Note: We know that theorically those SPAD used by the United Kingdom should be in this entry (as we are following an alphabetical order for the foreign users), but considering that they used it very widely we decided to make a dedicated entry just for them.
