context_page_description: The Albatros W.4 was a German floatplane derivative of the Albatros D.I fighter with new wing and tail surfaces of greater span than the D.I. One hundred eighteen examples were built between June 1916 and December 1917. The aircraft operated in the North Sea and Baltic theatres and later served as training aircraft.
  The W.4 was powered by the same 120 kW Mercedes D.III engine fitted to the D.I and based on the same fuselage. The first production series W.4s were armed with one lMG08 7.92 mm machine gun. Later aircraft carried two guns.
