Lack of good mid-war alternatives forced French authorities to try to extend the lifetime of the Voisin 3 and 5 two-seat pushers. The 300hp Hispano-Suiza engine was desired, but shortages forced the Voisin 8 to use the 220hp Peugeot 8Aa instead. This larger and heavier engine necessitated a larger airframe. The Type 8's served from November 1916 through late 1917, when they were phased out in favor of Voisin 10's. The factory designated the Type 8 as the BN2 or the LAP, and a cannon-armed variant was also produced (and is separately available).
