Development

The Voisin XII was a long-range night bomber with four Hispano-Suiza 8Bc engines mounted in pairs in tandem. The aircraft was built in response to the BN2 requirement for a long-range night bomber. One prototype was built and test flights were successful, but the war's end precluded the Voisin XII from being ordered into production.[1]

The Voison XIII night-bomber or Type E.87-2 was a proposed development of the Voisin XII, it was not built.[2]
