Albatros W.4

 

1st Flight 1916

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, including prototypes 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 (160 hp) Mercedes D.III engine fitted to the D.I and based on the same fuselage.

The first production series W.4 was armed with one lMG08 7.92 mm (.312 in) machine gun.

Later aircraft carried two guns.
