Hansa-Brandenburg W.27
 The Hansa Brandenburg W.27 and W.32 were prototype fighter floatplanes developed in parallel in Germany during World War I. They were developments of and intended replacements for the W.12 then in service and differed from each other principally in the choice of powerplant the W.27 with a Benz Bz.IIIb and the W.32 with the same Mercedes D.III that the original W.12 used.
