A true rival over the Belgian shores to the Spad XIV
The Albatros W.4 was a German floatplane derivative of the D.I fighter with new wing and tail surfaces of greater span. 118 examples (including three prototypes) were built between June 1916 and December 1917,[1] operating in the North Sea and Baltic theatres and later as trainers.
Powered by the same 120 kW (160 hp) Mercedes D.III engine fitted to the D.II and based around the same fuselage, the W.IV was armed with either one (first series) or two 7.92 mm (.312 in) machine guns lMG08.
