[Andrey Kuznetsov]

Thanks to Leon, I finally managed to see this old article.

Out of curiosity, I checked the table 22: Verteilung der Verluste (Totalverluste und beschädigte Maschinen) der Luftwaffe an Frontflugzeugen (Juni bis Oktober 1944).
I chose this table because the document he refers to (RL2-III/946) has already been digitised by the BA MA. The document was compiled by Gen.Qu.6.Abt.(V) from Summarische Verlustmeldungen.

Olaf Groehler repeated the breakdown by theatres of war and aircraft types as is.
Since there are no necessary totals, the calculation is quite laborious, and I calculated as examples only fighters and ground attack planes.

The results are as follows (total lost + damaged):

Jagd:

Süd [Lfl.2 and Lfl Süd-Ost]
durch Feindeinwirkung: 90+44 = 134
ohne Feindeinwirkung: 45+96 = 141
sum: 275
Groehler: 275

West [Lfl.3 and Lfl.5 (West)]:
durch Feindeinwirkung: 1363+267 = 1630
ohne Feindeinwirkung: 258+677 = 935
sum: 2565
Groehler: 2662

Erweitertes Reichsgebiet [Lfl Reich]
durch Feindeinwirkung: 1044+273 = 1317
ohne Feindeinwirkung: 621+1234 = 1855
sum: 3172
Groehler: 3162

Ost [Lfl.1, 4, 5 (Ost), 6]
durch Feindeinwirkung: 425+169 = 594
ohne Feindeinwirkung: 167+297 = 464
sum: 1058
Groehler: 1058

Schlacht:

Süd [Lfl.2 and Lfl Süd-Ost]
durch Feindeinwirkung: 5+1 = 6
ohne Feindeinwirkung: 6+3 = 9
sum: 15
Groehler: 15

West [Lfl.3 and Lfl.5 (West)]:
durch Feindeinwirkung: 16+6 = 22
ohne Feindeinwirkung: 0+1 = 1
sum: 23
Groehler: 23

Erweitertes Reichsgebiet [Lfl Reich]
durch Feindeinwirkung: 31+10 = 41
ohne Feindeinwirkung: 53+90 = 143
sum: 184
Groehler: 186

Ost [Lfl.1, 4, 5 (Ost), 6]
durch Feindeinwirkung: 469+186 = 655
ohne Feindeinwirkung: 185+289 = 474
sum: 1129
Groehler: 1119

Thus, he was clearly honestly calculating what was in the document. But since the Excel was not yet available, he made several arithmetical errors. Curiously enough, they are almost all in favour of western allies. This is not what many people expected him to do. However, this is a random sample, perhaps other figures are wrong in the opposite direction.

It seems that in the document in Lfl. Reich also units on the rest, replenishment or training are counted. Otherwise it is not clear, for example, what are the 266 ground attack planes (average monthly strength) in the Lfl. Reich in June 1944, which suffered only non-operational losses (Betriebsverluste).

Best regards,
Andrey
