Hansa-Brandenburg W.34 was a prototype German two-seat, single-engined floatplane, which had been designed by Hansa und Brandenburgische Flugzeugwerke during World War I.

Development

The W.34 was similar in design to the W.33, but was powered by a Basse und Selve BuS.IVa six-cylinder water-cooled engine. The first prototype flew in 1918, shortly before the Armistice.^[1] The other two prototypes were operated by the Finnish Navy following the Versailles Treaty and used for coastal defence, being re-engined with Fiat A.12bis engines.
