The Villiers V made its first public appearance at the 1926 Paris Aero show, possibly before its first flight.
Its engine was a 340 kW (450 hp) water cooled W-12 Lorraine-Dietrich 12Eb in a cowling which followed the outline of the three separate cylinder blocks.
The pilot's open cockpit was ahead of the trailing edge, under the upper wing cut-out, with the gunner close behind.
[1] The tail unit was conventional, with a broad chord, clipped triangular tailplane mounted on top of the fuselage and fitted with separate, round edged, balanced elevators.
[1] The night fighter was tested by the military under the designation Vil 5CN2 but was found not to provide enough improvement over existing equipment to justify production.
