/ Hansa-Brandenburg W.25
The Hansa-Brandenburg W.25 was a German floatplane fighter of the World War I era.
The W.25 was an improved version of the KDW with a modified biplane cellule with conventional inter-plane struts.
One prototype was built, and the aircraft competed with the Albatros W.4, the W.4 demonstrated a better flight performance.
Therefore, Hansa-Brandenburg returned the W.25 to its factory for modification with a second pair of ailerons on the lower wing.
The W.25 was not ordered into production as the Imperial German Navy lost interest in single-seat floatplane fighters.
