Heinkel He177 Eger-Cheb Production

[schwarze-man]

Interestingly, my data shows over 7,300 DB610 engines built. That was quite an expensive project, with limited success.

Schwarze-man: do you happen to know the annual split of DB610's produced by DB Genschagen? The other producer was Bussing, and I have the Bussing figures, but have never seen the DB production split.

Thanks and best regards,
Juha

Is this book useful and accurate?

Hi Juha,
The figures I have, from the DB records copied by BIOS after the war:
Genshagen DB610 production: 1942-1,088. 1943-1,734. 1944-2,188.

Hi Schwarze,

And thanks a lot!

So, the total DB610 output would be as follows:

Year-DBGen-Bussing-Total
1942-1088-241-1329
1943-1734-425-2159
1944-2188-445-2633
Total-5010-1111-6121

This would be good for ~3000 He177's (without reservation for any spares), and for over 2000 a/c with 1/3rd reservation for spares. At least for me, this seems to be somewhat too much.

As for the Bussing numbers, they come from one of the USSBS -reports and are for the amount of coupled DB605-units (that is DB610-units). I wonder if the BIOS-report counts are for the DB605's allocated for the DB610 -units, and thus should be actually divided by two?
That would give roughly 3000 engines, which would be good for roughly 1000 a/c (which was the amount of DB610-engined A-3's and A-5's) with 1/3rd reservation for spares. Any thoughts on this?

Cheers,
Juha

A bit less than 400 pcs He177 hv been delivered by end of 1943, nd planned till 06-46 are 2500 more pcs
By june 44, a bit more than 1000 hv been delivered nd only 137 pcs are still to be del. f. the year end.

Hi Juha!

The BIOS report was compiled from DB records at Unterturkheim. They refer to the DB610 specifically as "610=2x605 coupled". I would expect that the figures quoted are exactly as recorded by DB. The other figures for the 610 production are Niedersachsische Motorenwerke: 1942-482, 1943-850, 1944-970.
That gives totals:
1942-1570, 1943-2584, 1944-3158. Grand total, 7,312.

I guess a review of the actual DB archiv would be one way to try and confirm the record.
Best wishes,
SM

Hi Schwarze,

Thanks for the additional data.

But, here I noticed something odd...

The Bussing (NAG) factory is actually the very same as Niedersächsische Motorenwerke GmbH:
https://www.deutsche-digitale-biblio...VSVRT766GXMIHH

Here it also says Bussing (or Niedersächsische MW) produced a total of 15.872 aero-engines between 1939 and 1944:
https://de.wikipedia.org/wiki/Nieder...e_Motorenwerke

This total is also verified by the USSBS -report, that I have. And there the DB610 -numbers are "halved" from the DB605 -numbers, see:

Your data shows for the Nied.MW:
1942-482
1943-850
1944-970

These are exactly "doubles" to my data on Bussing (from the ultra-detailed USSBS), except for the last year. But you see the pattern:
1942-241
1943-425
1944-445

Best Regards,
Juha
