The Breda Ba.100 project was rejected by the DGCA management. The reason for this was that, despite the use of a very powerful Alfa-Romeo 135 RC.32 engine (along with the Avis CO.2) and the highest calculated performance, the flight characteristics of the project did not guarantee it a great qualitative advantage over the fighters of the previous generation. In addition, the contra-rotating propellers with which the engine was to be equipped were still in the development stage.
In conclusion, the Alfa-Romeo 135 RC.32 aircraft engine, for which the Ba.100 was developed, had serious reliability problems. Although many mechanical defects were eliminated during testing, the engine continued to suffer from overheating and vibrations, which were so severe that it was rejected. Approximately 150 engines were manufactured by 1944, none of which were installed in operational combat aircraft.
