So is the argument that radial engines don't require weight for a cooling system.
The Fw-190A had the nose extended twice (once prior to mass production) in order to provide adequate cooling for the BMW801 engine. Each nose extension added weight to the aircraft and affected aircraft handling.
On a liquid cooled engine you also have serious amount of weight from coolant liquid and raditors, piping, and more drag from these installations.. on a radial like BMW 801, none... so dry weight alone is a bit misleading.
The cooling system for a Merlin or Allison started at 300lbs for the low powered ones and went up. Cooling system for a 222 could run 500-600 pounds. The entire fuselage of the Fw 190 might not have weighed 600pounds.
I don't have a problem with continuing development of the BMW801 radial engine. But if RLM must retool a factory for DB603 engine production it should be something other then the Ostmark Jumo 222 plant.

Retooling the Ostmark engine plant to produce DB603s destroyed several promising German aircraft programs.how many airframes actually made it into the air powered by Jumo 222s
As far as I am aware the Jumo 222 was a troublesome engine which needed a lot of work before it was ready for production.
Detuning early series to overcome reliability issues sounds a lot like what heppened to the Vulture.
The Daimler-Benz DB604 was cancelled in 1942 IIRC. Does anybody know the reason why?
Was it unreliable? Fell foul of production priorities?
The DB604 was only a little bigger in capacity than the DB603 (46.3l vs 44.5l) but was more powerful. It did weigh about 160kg more.

Bomber B program aircraft.
Do-317. The Do-317 design was never considered that promising, dropped down the priority lists and showed little improvement over the Do-217 when it did fly
Ju-288. Doomed by the combination of the unreliable Jumo 222 and the aircraft's own complexity
Fw-191. Flight testing of first four aircraft showed the Fw-191 was so poor that the project was abandoned before the flight test program was even finished
Do-435 night fighter. Spin off of the Do-335 with lower development priority. It never flew, so I'm not sure how the lack of Jumo 222s "destroyed" the project
He-219 night fighter. Flew fine with DB 610s, if a little underpowered. Follow on 219B was to have 222s, but only a handful of aircraft were made, and the unreliability of the 222 reared its head again
Dr. Tank was designing a Fw-190 variant powered by the Jumo-222.
Ju-488 heavy bomber. A 1944 last-ditch strategic bomber program? This was destroyed by the
One of the He-177B prototypes was supposedly fitted with Jumo 222 engines.
There are probably more if you want to spend time searching.
