Friedrichshafen G.IIIa

When the Friedrichshafen G.III lost an engine, it could be steered only with the greatest of effort. The Friedrichshafen G.IIIa sought to correct this with a box-tail double-rudder. Other improvements included the Gotha-style tunnel for firing to the downward rear quarter and Flettner tabs on the ailerons.

Austria-Hungary had tried to buy some G.IIIs in 1918, but a fire at the factory resulted in a cancellation of the orders. Oeffag was preparing to build G.IIIa's in autumn 1918 but none had been completed by the Armistice.
