I cant understant how the differences between the Dainler Benz 605 and 603 fit in to german plans for aircraft production. The 605 was the most produced german engine, with production in full swing for late bf109s. But the 603 was never really produced in high numbers. Only fitted the me-410, which we are still dicussig its usefulness, and was the planned engine for the Ta-152C and DO-335, both of which never saw combat. My question is why the germans never went seriously about creating a single engine fighter with the 603? As far as I know this engine was to big to fit the airframe of a 109, right?
