Aviatik 30.30

  The drawings for the Aviatik 30.30 high-altitude fighter, the most powerful fighter built by Aviatik, were completed in May 1918. It was powered by a 230 hp Hiero engine. The design provided for an "open" center-section, giving good visibility, and accessible machine guns - features pilots had found lacking on the Aviatik D.I. Although good performance was recorded at the July 1918 Fighter Evaluation, the 30.30 apparently did not find favor with the pilots. In Cavigioli's book the 30.30 is incorrectly designated as the prototype for the Aviatik D.III when, in fact, Flars had not included any Aviatik fighter for production through March 1919. In September 1918, the 30.30 prototype was undergoing reconstruction at the Aviatik factory, but details are lacking.

Aviatik 30.39

  The Aviatik 30.39 fighter, similar to the 30.30 but powered by a 225 hp Daimler engine, competed in the July 1918 Fighter Evaluation at Aspern. Weighing slightly less than the 30.30, its rate of climb was about equal, but it was slower than the production Aviatik D.I series 338. In September 1918, the 30.39 was at Aviatik-Esslingen awaiting modification. Further information is lacking.
