The Voisin VIII is a French two-seat biplane pusher which was built in two versions, one fitted with a 37mm Hotchkiss cannon (the LBP or Ca.2), and the other as a conventional bomber (the LAP or Bn.2).

Two versions were to be built, a conventional bomber, and an aircraft armed with a large single shot 37mm Hotchkiss cannon as was used on the Voisin IV.

On some aircraft, the observer's gun was mounted on a ring that was tilted to make movement forward easier against the wind.

Unlike with the Voisin IV, installation of the cannon did not require that the top wing be staggered forward to maintain fore-aft balance.

Like the Voisin VII, the VIII was fitted with two large strut mounted teardrop fuel tanks that could be jettisoned in the event of a fire.
