Germans were involved already in the summer of 1943 in the testing of new Italian aircraft. They liked G.55s and were interested to have deliveries of them by Fiat. They tested other Italian aircraft, even Z.1018. Sadly for CRDA they did not have a good opinion of the "Leone", claiming that it was not better than the already obsolete Ju 88A-4 and even inferior to the Z.1007ter. The Italian plans to produce bombers were severely weakened by this decision. Germans offered their Me 410 or Ju 188 in exchange for Italian G.55s, in the process giving Italy worthless aircraft in exchange for airplanes which would be valuable in defense of Germany. The removal of Benito Mussolini on 25 July and the Armistice stopped these plans. The Germans took control of all Italian industries in central and north Italy.
