Voisin XII

The Voisin XII was a prototype French two-seat, four-engine biplane night bomber built near the end of the First World War that never entered service. It was built in response to the BN2 requirement for a long-range night bomber and carried four Hispano-Suiza 8Bc V-8 water-cooled engines of 160 kW (220 hp) each, mounted in pairs in tandem tractor and pusher nacelles. Spanning 30 metres and weighing 3,500 kg empty, it was one of the largest aircraft Voisin built, with a specified maximum speed of 145 km/h, a range of 700 km and a bomb load of 800 kg. One prototype flew and its test flights were successful, but the end of the war meant it was never ordered into production. The Voisin XIII night bomber, the Type E.87-2, was a proposed development that was not built.
