TheVoisin III was a FrenchWorld War I two-seatpusherbiplane multi-purpose aircraft developed byVoisin in 1914 as a more powerful version of the 1912Voisin L. It is notable for being the aircraft used for the first successful shooting down of an enemy aircraft on October 5, 1914, and to have been used to equip the first dedicatedbomber units, in September 1914.

The first Voisin III was initially powered by a single 97 kW (130 hp)Salmson M9 engine water-cooled 9 cylinderradial engine, while later examples used the similar 110 kW (150 hp) Salmson P9 or R9. It had a range of 200 km (120 mi), a top speed of 105–113 km/h (65–70 mph) and a ceiling of 3,350–6,000 m (10,990–19,690 ft) depending on engine and manufacturer. The pilot was ahead of the passenger, who could fire weapons, release bombs or take photos, depending on the mission. It incorporated a light steel frame structure which made it more durable when operating out of makeshift wartimemilitary aviation airfields.
Many aircraft were armed with aHotchkiss M1914 machine gun mounted on the fuselage operated by a standing observer. Some variants could carry up to 150 kg (330 lb) of bombs.

As one of the main types that the FrenchAviation Militaire chose to standardize on in 1914, the Voisin III quickly became one of the most commonAllied bombers early in the war. Significant numbers were purchased by the French and theImperial Russian Air Force. Russia ordered more than 800 from France and built a further 400 under license atAnatra,Breshnev-Moller,Dux,Lebedev andSchetinin.[1] Over 100 were built in Italy bySociete Italiana Transaera (S.I.T.),[1] and 50 in the United Kingdom,[1] while small numbers were purchased by Belgium and Romania. One French aircraft was forced to land in Switzerland in 1915 after running low on fuel in combat with a German aircraft and was put into service with the SwissFliegerabteilung.[2]
Like many aircraft of its era, Voisin III was a multi-purpose aircraft. Its missions included day- andnight bombing,reconnaissance,artillery spotting andtraining.

While flying a Voisin III, Sergeant Joseph Frantz and Corporal Louis Quénault ofEscadrille V.24 shot down a GermanAviatik B.I flown by Oberleutnant Fritz von Zangen and Sergeant Wilhelm Schlichting ofFFA 18 overJonchery, nearReims on October 5, 1914.[3] This was the first time an aircraft had been brought down with small arms fire from another aircraft.[3]
Quénault fired two 48-round magazines from an 8 mm (0.31 in)Hotchkiss M1909 machine gun at the Germans who returned fire with rifles. When it jammed, he continued firing with a rifle until he succeeded in bringing them down.[4][5]
Previously,Pyotr Nesterov had successfully brought down an enemy aircraft, however that was by ramming.
The Voisin III is notable in being among the earliest dedicated bombers. The steel frame construction of the aircraft enabled a bomb load of approximately 150 kg (330 lb) to be carried.
France was the first country to organize dedicated bomber units, using the Voisin III. ThreeEscadrilles (squadrons) of the aircraft comprised the first bomber group, GB1 (groupe de bombardement 1), formed in September 1914 under the leadership of Commandant de Goÿs.[6] de Goys’ contribution both as a tactical leader and theoretician is significant in developing the theory and practice of long range bombing sorties. An almost unopposed bombing campaign was conducted by GB1 during the early months of 1915, culminating in a retaliatory attack against theBadische Anilin Gesellschaft atLudwigshafen, Germany, on 26 May 1915,[6] shortly after theGerman Army introducedpoison gas in battle. Of the 18 aircraft which took part, only Goÿs himself failed to return when his Voisin suffered a mechanical failure.[6]
Following the success of GB1, other bomber groups were formed and successful daytime attacks on targets within Germany ensued throughout the summer and autumn of 1915. As many as 62 aircraft were involved. By 1916 the Voisin III was clearly obsolete and had become dangerously vulnerable to Germanfighter aircraft. With mounting losses, the Voisin III was withdrawn from daylight operations and restricted to night bombing. Among other types, it was replaced by the similarVoisin V.

An original 1915 Voisin III B.2/LAS, number 955, is on display at theMusée de l’air et de l’espace[11][12] atLe Bourget nearParis.
A full-size Voisin replica is on display at thePearson Air Museum inVancouver, Washington however it only loosely represents the Voisin L/LA/LAS family and not a specific version.[13]
