Voisin III

The Voisin III was a French two-seat bomber and ground attack aircraft of World War I, one of the first of its kind. It is also notable for being the first aircraft in the war to win an aerial fight and shoot down an enemy aircraft.

It was a pusher biplane, developed by Voisin in 1914 as a more powerful version of the 1912 Voisin I design. It also incorporated a light steel frame which made it more durable when operating out of the temporary wartime military aviation airfields.

The first Voisin III was powered by a single 120-horsepower Salmson M9 engine, later the 150 hp P9 and R9. It had a range of 200 km, top speed of 105–113 km/h and ceiling of 3,350 m–6,000 m (sources vary).

Earlier aircraft were armed with a Hotchkiss M1914 machine gun on the fuselage operated by a standing observer, later models had 37 mm or 47 mm guns for ground attack. It could carry up to 55 kg, 60 kg or 150 kg of bombs (sources vary).

Early in the war, the Voisin III became the most common Allied bomber. Significant numbers were purchased by the French Air Force and the Imperial Russian Air Force. Russia ordered over 800 from France and built a further 400 under license at DUX in Moscow. Around 100 were built in Italy, and 50 in the United Kingdom, while smaller numbers were purchased by Belgium and Romania.

Like many other aircraft of its era, Voisin III was a multi-purpose aircraft. Its missions included reconnaissance, artillery spotting, training, day and night bombing as well as ground attack.
