The Henry Farman HF.30 was a two-seat military biplane designed in France around 1915, which became a principal aircraft of the Imperial Russian Air Service during the First World War. Although it was widely used on the Eastern Front, and by the factions and governments that emerged in the subsequent Russian Civil War, it is not well known outside that context: the HF.30 was not adopted by other Allied air forces, and the manufacturers reused the "Farman F.30" designation for the Farman F.30 in 1917.
