The Nieuport IV was a French-built sporting, training and reconnaissance monoplane of the early 1910s.
Societe Anonyme des Etablissements Nieuport was formed in 1909 by Édouard Nieuport. The Nieuport IV was a development of the single-seat Nieuport II and two seat Nieuport III.A. It was initially designed as a two-seat sporting and racing monoplane, but was also bought by the air forces of several countries. It was initially powered by a 50 hp (37 kW) Gnome Omega rotary engine, which was later replaced by more powerful rotaries. [1]
The first Nieuport IVs were built in 1911 and production continued well into World War I in Russia. [2] The design was adopted in small numbers by most air arms of the period, although the Imperial Russian Air Service was the largest user.
The IV.G was one of the principal aircraft used by the Imperial Russian Air Service during its formative years, with roughly 300 being produced locally by the Russo-Baltic Wagon Works and Shchetinin in St. Petersburg, and the Dux Factory in Moscow. [3] Lt. Pyotr Nesterov performed the first ever loop, over Kiev in a model IV.G on 27 August 1913 for which he was placed under arrest for 10 days for "undue risk to government property" until the feat was repeated in France by Adolphe Pégoud; Nesterov was then awarded a medal and a promotion. [4]
The French government equipped a single squadron with Nieuport IV.Ms, Escadrille N12 initially based at Reims, having purchased at least 10. This unit continued to operate Nieuport monoplanes after the start of World War I, slowly replacing them with other types as attrition reduced their numbers. [5]
The Swedish Air Force was presented with a IV.G in 1912 by four individuals, becoming one of the first aircraft of that force, [1] which was later joined by a second IV.G in 1913, and a IV.H transferred from the Swedish Navy. [6]
The Japanese Army operated one IV.G and one IV.M, which were designated as Army Nieuport NG2 aeroplane and Army Nieuport NM aeroplane respectively, [7] with the NG being flown in the Tsingtao campaign in September and October 1914 alongside four Maurice Farman MF.11s. [8]
One of the first batch of aircraft purchased by the British Army's Air Battalion Royal Engineers (the precursor to the Royal Flying Corps) was a Nieuport IV.G and serialed B4. Additional IV.G monoplanes were purchased from private individuals including one from Claude Grahame-White and another from Charles Rumney Samson, plus three others. [9] [10] The Nieuport IVs were in service when the RFC carried out an investigation into monoplane crashes. While this report covered an accident involving a Nieuport IV, it determined the accident to be a result of improper maintenance which lead to engine failure, rather than a structural failure such as with the Bristol monoplane and Deperdussin monoplane whose structural deficiencies led to the Monoplane Ban. [11]
Argentina purchased a single IV.G named la Argentina which served with the Escuela de Aviation Militaire. [12]
In Greece, a IV.G was bought privately and named Alkyon. After being the first aircraft to fly in Greece, it was resold to the government which used it during the First Balkan War in 1912, flying from Larissa. [12]
Siam purchased 4 IV.Gs which were used as trainers at Don Muang airfield. [13]
Spain purchased one IV.G and 4 IV.Ms which were used by the Escuela Nieuport de Pau for training before 3 were transferred to an operational school (Escuela) at Tetuán, (Spanish Morocco) which then moved to Zeluán, remaining operational until 1917. [6]
Italy's 1st Flottiglia Aeroplani of Tripoli operated several Nieuport IV.Gs during the Italo-Turkish War, one of which became the first aeroplane to be used in combat when it flew a reconnaissance mission against Turkish forces on 23 October 1911. [14] It narrowly missed out to a Bleriot XI with the same unit for the honor of being the first aircraft to drop a bomb on enemy forces. The pilot who carried out this mission, Capt. Maizo, also became one of the first victims of anti-aircraft fire when he was shot down by an Austrian cannon weeks before the war ended in 1912. [14]
Two officers of the former Spanish Air Force, Emilio Herrera and José Ortiz Echagüe, Captains of the Corps of Engineers of the 1st Expeditionary Air Squadron, on February 14th, 1914, crossed the Strait of Gibraltar in a Nieuport IV.M, a flight between Tetouan (Morocco) and Seville (Spain), being the first intercontinental flight of the aviation history. [15]
That day, [16] Captains Herrera and Ortiz Echagüe took off from Tetouan, then the capital of the Spanish Protectorate in Morocco, at 1:30 p.m. and landed at Tablada Aerodrome (Seville) shortly after 6 p.m., thus taking almost 5 hours to cover the 208 kilometers in a straight line that separate the two cities. For the first time in history, an aeroplane crossed the Strait of Gibraltar, and for the first time an intercontinental flight was also made.
Despite not being a very long flight, they had to face numerous difficulties. The worst thing was the strong winds blowing in the Strait of Gibraltar, considering the limitations of their Nieuport IV-M (80-horsepower Gnome engine). The opposition of the Riffian tribesmen to the Protectorate in the form of continuous attacks to the spaniards (wich will end in the Rif War) was another element of danger. Also British government, prohibited the two pilots flying over Gibraltar.
The aviators, on leaving Tetouan, had to fly along the Martín River to its mouth, flying at a height of only 200 metres. Then they skirted the African coast until they reached Ceuta, where they raised the aircraft to almost 2,000 metres. At this height they crossed the strait whipped by a strong easterly wind. After entering the peninsula and rising a little higher to clear the mountains, they sighted Jerez, and from there headed for Seville, where they entered following the line of the Guadalquivir.
At the Tablada Aerodrome His Majesty King Alfonso XIII was waiting for them, to whom they delivered a message from the High Commissioner of Spain in Morocco. It was one of the first milestones of Spanish aviation, which in the following decade would experience its golden age with the great air raids.
The Swedish Air Force maintained their first model IV in airworthy condition until 1965. [17] This aircraft is now preserved in the Flygvapenmuseum at Malmen near Linköping. [18] The Museo del Aire at Cuatro Vientos near Madrid has a full-scale replica of one of their model IVs. [19]

The Air Battalion Royal Engineers (ABRE) was the first flying unit of the British Armed Forces to make use of heavier-than-air craft. Founded in 1911, the battalion in 1912 became part of the Royal Flying Corps, which in turn evolved into the Royal Air Force.
Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars.
The Nieuport 17 C.1 is a French sesquiplane fighter designed and manufactured by the Nieuport company during World War I. An improvement over the Nieuport 11, it was a little larger than earlier Nieuports and better adapted to the more powerful engine than the interim Nieuport 16. Aside from early examples, it had the new Alkan-Hamy synchronization gear, permitting the use of a fuselage-mounted synchronised Vickers gun firing through the propeller disc.
The Nieuport 28 C.1, a French biplane fighter aircraft flown during World War I, was built by Nieuport and designed by Gustave Delage. Owing its lineage to the successful line of sesquiplane fighters that included the Nieuport 17, the Nieuport 28 continued a similar design philosophy of a lightweight and highly maneuverable aircraft.
The Blériot XI is a French aircraft from the pioneer era of aviation. The first example was used by Louis Blériot to make the first flight across the English Channel in a heavier-than-air aircraft, on 25 July 1909. This is one of the most famous accomplishments of the pioneer era of aviation, and not only won Blériot a lasting place in history but also assured the future of his aircraft manufacturing business. The event caused a major reappraisal of the importance of aviation; the English newspaper The Daily Express led its story of the flight with the headline "Britain is no longer an Island."
The Antoinette military monoplane, also known as the Antoinette Monobloc or the Antoinette-Latham was an early 3-seat monoplane built in France in 1911 by the Antoinette company in the hope of attracting orders from the French military. It featured a futuristic and aerodynamic design with innovative elements that were ahead of its time, including unbraced cantilever wings, an enclosed fuselage and wheel fairings, and an engine with steam cooling and direct fuel injection. However, due to an under-powered engine, it was barely able to fly and failed to attract orders.
The Nieuport VI was a sport monoplane produced in France in the 1910s, a further development by Nieuport along the same general lines as the Nieuport II and Nieuport IV, differing mainly from the Nieuport IV in being slightly larger. Like the Nieuport IV, it was used by various military air arms as a reconnaissance aircraft and trainer.
The Nieuport 12 was a French sesquiplane reconnaissance, fighter aircraft and trainer used by France, Russia, Great Britain and the United States during World War I. Later production examples were built as trainers and served widely until the late 1920s.

It was used by the French Army and the British Royal Flying Corps. It is notable for the extensive use of metal in its construction, unusual in an aircraft of its time.
The Gnome 7 Omega is a French seven-cylinder, air-cooled aero engine produced by Gnome et Rhône. It was shown at the Paris Aero Salon held in December 1908 and was first flown in 1909. It was the world's first aviation rotary engine produced in quantity. Its introduction revolutionized the aviation industry and it was used by many early aircraft. It produced 37 kW (50 hp) from its 8 L (490 cu in) engine capacity. A Gnome Omega engine powers the 1912 Blackburn Monoplane, owned and operated by the Shuttleworth Collection, the oldest known airworthy British-designed aeroplane worldwide. A two-row version of the same engine was also produced, known as the Gnome 14 Omega-Omega or Gnome 100 hp. The prototype Omega engine still exists, and is on display at the United States' National Air and Space Museum.
