The Phönix 20.24 was a prototype German fighter plane built in the last months of World War I.

Development

The Phönix 20.24 was similar to the D.III but differed in having a semi-monocoque fuselage and an Austro-Daimler engine. Two prototypes were built with the serials 20.24 and 20.25, entered in the July 1918 fighter competition but remained at the prototype stage only.[1][2]

Production aircraft would very likely have been allocated the LFT designation Phönix D.IV, according to Phönix company records.[1]
