Jane's All The World Aircraft 1919

This machine was also designed as a ship single-seater fighter, and was of very much the same overall dimensions as the W.B.IV.
  Instead of placing the engine over the C.G. and driving the propeller by a shaft passing between the pilot's legs, and designing the fuselage to provide the necessary buoyancy for flotation after alighting on the sea, the. conventional engine in front arrangement was adopted, and the necessary buoyancy bad to be provided by external air bags.

H.King Armament of British Aircraft (Putnam)

W.B. V. This contemporary of the W.B. IV had an armament of even greater - indeed exceptional interest, though the airframe engine layout was conventional. It was specifically designed for the French Hispano-Suiza canon Puteaux installation, of the type that became generically known as moteur canon. Although a 37-mm gun was actually installed in the first W.B. V, it found no acceptance among pilots, who were as cramped by its presence in the cockpit as they were disconcerted by the possibility of malfunctioning. French pilots using a similar installation in SPADs were said to become bemused by the explosive fumes. A fixed Vickers gun was therefore substituted, this being mounted on top of the fuselage with the breech casing faired. As secondary armament there was a free Lewis gun on a pylon mounting ahead of the cockpit and firing through an aperture in the centre-section.

  Developed in parallel with the W.B.IV, but of more conventional design, the W.B.V single-seat shipboard fighter was intended to carry a 37-mm Puteaux cannon between the cylinder blocks of its 200 hp Hispano-Suiza eight-cylinder water-cooled engine. It featured folding wings, a jettisonable undercarriage and inflatable flotation bags beneath the underside of the leading edge of the lower wing. Three prototypes of the W.B.V were ordered, the first of these flying on 3 December 1917, but the engine-mounted cannon was quickly removed and a more conventional armament mounted, this comprising a synchronised 0.303-in (7,7- mm) Vickers gun and a 0.303-in (7,7-mm) Lewis gun on a tripod ahead of the cockpit. The second prototype W.B.V was completed and flown in 1918, but further development was abandoned before the end of World War I.
