DB 605 X DB 603

[RATHED]

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?

There were other serial produced a/c with DB 603:
Do 217 N&M
Do 335 (preproduction series)
He 219
Me 410

Prototypes:
Fw 190C (only research stage with DB 603S/G)
BV 155 (very promising a/c with DB 603U)
Ta 152C (planned production version with DB 603LA/L)
Fw 190D-14/15 (planned production version with DB 603EM)

The fighter Fiat G.56 was successfully tested with a DB 603, proably a DB 603A or 603AA. Pilots were delighted with this aircraft, fast and very maneuverable.

AFAIK the Me 209 and Me 309 were also tested with a DB 603 but they proved to be more cost intensive than the Bf 109 while being slower (Me 209) or only slightly faster (Me 309).
