The Steel-framed Voisin pusher biplane was in service with the French Army at the outbreak of war. A batch of the Voisin LA (Type 3) with 120hp Canton Unne (Salmson) engines was even waiting to be delivered to Russia. Escadrilles VB1, 2 and 3 with 18 Voisins formed the first French Groupe de Bombardment in November 1914 and carried out some very successful raids until September 1915 when day-bombing was stopped because of the superior German fighter aircraft, and Voisins changed to night-bombing. 37 Voisin LAs with 200hp Hispano-Suiza engines were obtained by the RNAS and used in the Aegean, Africa and Mesopotamia. British and French built Voisins were used on the Western front by Nos. 4, 5, 6, 7 and 16 Squadrons RFC and in Italy, this machine formed the operational establishment of five squadriglia.
The Nieuport 10 two-seater biplane was the earliest line of the famous French fighter aircraft which came to be used by France, Britain and Italy. It was operated by the RNAS in the Dardenelles where some of the Mk. 10s were converted to single seaters armed with a Lewis Gun. It was replaced by a larger and stronger Nieuport 12 which was used by Nos. 1, 4, 5, and 46 Squadrons RFC and by Nos. 1, 2, 3, 4, 7, and 10 Squadrons RNAS.
