Jane's All The World Aircraft 1919

The Beardmore single seater torpedo-carrying, folding ship-aeroplane, type W.B. VI., was the result of one of the many efforts to produce a satisfactory, fast torpedo-carrier. The general arrangement is on conventional lines, with the pilot well hack in the fuselage.
   The under-carriage is arranged to permit the stowage and dropping of a torpedo under the centre of gravity.

The W.B.VI

  The W.B.VI was a proposed torpedo carrying biplane. It followed conventional thinking in being a single-engine single-seat biplane. The pilot sat well back in the fuselage. The undercarriage was arranged so that the torpedo was suspended under the centre of gravity. A 350-hp Rolls-Royce engine was the nominated power plant.


The W.B.VIa to W.B.VId series

  Although they bore the W.B.VI designation, these three civil aeroplanes with folding wings were all different. The W.B.VIa was a six passenger machine that was started but construction was never completed. The proposed engine was a 500-hp Galloway Atlantic. The W.B. VIb was a projected two seat civil aeroplane. The W.B.VIc was a small, single seat biplane. The W.B.VId was a project only. Six passengers were carried in two fuselages with two 230-hp B.H.R engines driving the airscrews through shafts.
