Junkers Giant Seaplane of 1917
In November 1917 the RMA asked Junkers for the developement of a Giant Seaplane. An order was placed for three prototype aircraft, which were named G-Eindecker (Giant Monoplane) according to Junkers design layout. The Junkers proposal was a combined seaplane on floats or landplane on wheels, as Junkers wanted to gather experience from this aircraft for his R-Planes as well. In Summer 1918 Junkers informed the RMA, that the developement of the G-Eindecker would be delayed, as he gave more priority to the J11 seaplanes, which were also ordered by RMA at that time. Junkers idea was to gather experience from this much smaller seaplane and put this experience into the G-Eindecker developement. However, when the J11 was ready to fly, the end of World War I came up. Finally the military role of the G-Eindecker came to an end before further design work had started.
The prinicple layout, dimensions and performance data of the G-Eindecker were very similar to the G23/G24, which was developed during 1924/25. Therefore it seems, as if Junkers had taken principle ideas of the G-Eindecker for these later aircraft, especially for the military G24 variants as the K42 or the Fili built Ju-G1.
