I too have difficulty with this statement............. can you point us to the interview? does it specify circumstances of the claim?

[Crumpp]

Yeah, OK Batz,


I guess Squadron Signal, Osprey, and Schiffer Military History's are wrong and you are right.  You, Isegrim, and a few others need to get on the ball and write some editors, authors, and historians to correct them.

[GScholz]

*lol* Crumpp, are you saying the 190A's did have MW50?

[Batz]

And you along with your sources would be wrong about mw50 and the 190 A series just like you are with 90% of everything else you post on this forum.

Butch or Hohun can answer you more in depth if they so choose.

"Squadron Signal, Osprey, and Schiffer Military History's are wrong and you are right."

Yup, they have errors.

Sure, send off some letters for a book that will only have one edition published.

[Crumpp]

Yes 190A5's did have MW50.  They were 190A4's produced with it also,  Offhand I want to say it was the Umrustsatz 4.    The 190A5 was the first to have a boost system on the standard production model.

Maybe I should change first question....

How much preG14 109 had MW50 ?

If you would be so kind to translate it from Russian into English Ill post it here. But its big even in current unfinished state .

Wrong..... :rolleyes

Vodooo,

There is no pre G-14 with out mw50, the g14 is a g6 + mw50.

[butch2k]

There was no serialized installation of MW-50 system on the 190A, but tests were made on some prototype though.

As for the pre-G14 with MW-50, a lot of the G6/U2 and G5/U2 were reconverted to MW-50 use through kit issued in April 1944 (IIRC), at least 250 such kits were issued if i remember the figures in the report correctly.

[VO101_Isegrim]

G-14 was the first series to receive MW systems as standard on the factory, but there were retrofitting of older airframes like G-5 and G-6 before, the earliest date I found was April 1944, but they could have appeared a few months before than that already. These were usually the /U2 variants that had GM-1 and could be converted to MW 50 with ease.

Speed w. MW 50 was 569 km/h at 0m for the G-14 (or G-5/G-6 retrotfitted w. MW50), and 560 km/h for the G-14/AS (or G-5/AS or G-6/AS if equipped w. MW 50). This is quite similiar to La-5FN low altitude speeds...

/AS types were a bit slower at low altitudes because of their high-alt wide propellors, but a lot faster at altitude, ie. G-14 was 665 km/h at 5000m, G-14/AS 680 km/h at 7500m.

According to :
GL/C E5 Nr 26858/44 dated 25/May/1944

"Auf der musterbesichtigung in Staaken an 13.5.44 wurde festgelegt, dass der DLH Mustereinbau für die Erstellung der serienunterlagen massgebend ist. Ohne Einschaltung des CE2 oder CE5 änderte Messerschmitt an der in Staaken festgelegten anlage
1) die Rohrleitungs Nennweiten
2) den Einbauort des Niederdruckmanometers
3) zusätzlicher einbau eines rückschlagventile"
(...)
"für die 200 rüstsätze für die truppenmässige umrüstung auf MW50 anlage ist des in Staaken erstellte mustereinbau massgebend, NW8 für MW50 förderleitung. Die zellengebundenen einbauteile werden nach auskunft von CB2 im reparaturwerk Erfurt und bei DLH Staaken erstellt. Der einbau des anlagen bei der truppe erfolgt nach unterlagen Staaken."

As you can see my memory failed me a bit

Thx for info, Butch.

I think that fights were at 3-4 km.

[butch2k]

In fact it was just 200 kits and in May as proved in my post above, and note that existing /U2 on the production lines were also modified to use MW50 rather than GM-1 but kept their designation (even when fitted with the light alloy tank rather than the heavy insulated GM-1 one).
Consider that beginning in June/July 44 the G-6/U2 and G-6/U2/AS going out of the production lines were modified for MW-50 use.

[VooDoo]

My conclusion - that was 109 wo MW50. 200-250 is just too small number of planes to notice it.
