The Voisin 10 (or X) was a French two-seat pusher biplane built in two versions, either fitted with a 37 mm cannon (the LBR or Ca.2) or as a conventional bomber (the LAR or Bn.2). It first entered service in late 1917 but had poor performance relative to contemporary fighters so was often relegated to night operations. Despite its obsolescence, it would make up the bulk of front line night bomber escadrilles until the end of the war. This example is the 4th plane produced (not 4 as a serial) and flew with Escadrille V110. This fuselage is the only survivor of all the 900 Voisin 10's built.
