So, was there a JU-88 G-7??
 

I'm sorry if this comes under the heading of "dumb question", even sorrier if it comes under the heading of "very dumb question" :lol: But seriously guys, did the G-7 version of the JU-88 powered by the Jumo 213E with water/methanol injection exist??
If the version of the JU-88 powered by the Jumo 213E was not designated the "G-7", what was its proper designation?
How many of these aircraft were produced and when was their service introduction with the Nachtjagdgeschwader?

Thanks much!

Ju 88 G-7
 

Just happen to be looking through Brian Filley's "Junkers Ju 88 in Action pt 2", from Squadron. Accordingly the G-7 variant with Jumo 213E-1 engine was under development with 4 prototypes, but never entered production. The first 2 were destroyed by bombing in March 1945 and the latter 2 had not received their powerplants by war's end.

Thanks Don! So, what JU-88 was in operation with the methanol injected Jumo 213E engines? (I don't have that Squadron title.)

Ju 88 G-7
 

The Ju 88 G-7 was in production as the war ended, i.e., they were in the assembly process. There is no data I have seen that indicates that any were actually completed or flown, much less having made it to any operational unit. So the only Ju 88 G-series that appear to have actually made it to the end of the production line were the G-1 , G-6 and G-10. Forget the books, if there is no primary source material to support the claims, they fall in the category of unconfirmed rumors. There is a JFM organization with members from the WWII period, perhaps they have some more solid information supporting this subject.

Thank you Artie Bob!

I'm embarrassingly new to researching airplanes, my field has always been armor, but I have begun to absorb the realization that the books on certain subjects come up short. In the case of the JU-88, there aren't that many that I can find in English. So please be patient with me.

I must say that this Board is refreshingly informative and I am really enjoying reading some of the fantastic information posted here. My only regret is that I can't contribute in return as much as I ask.

So Guys, all of this still leaves the question of which model of the JU-88 flew with Jumo 213E engines?

Ju 88s with Jumo 213E
 

The answer to your question is fuzzy. The Ju 88 G-7 in various documents are shown to have been projected with either the Jumo 213E or DB 603E/F. Whether any production G-7s actually flew is questionable and if so, which engines were available at that time is also not clear. All data I have had access to indicates all G-6 production had Jumo 213A engines. There were prototype Ju 88s scheduled which had some G-7 features, V112 to V115. How many of these reached flight stage, I have not been able to confirm and if so, how many of the definitive G-7 changes had been incorporated. At least two apparently were completed, but damaged in a strafing attack at Brandenburg-Briest.
New information becomes available from time to time, just recently a photo came to the surface which shows a late war Ju 88 at Brandenburg, apparently with four bladed propellors, this would possibly be one of the G-7 prototypes.

Best regards,

Artie Bob

I think your answer is excellent Artie Bob! :D :D

But now I'm really puzzled. Us armor types are used to looking at a set of unquestioned stats: Panther Tank--maximum speed--55Kmph.
Now, I've seen statistics for the illusory JU-88 G-7 that quote its maximum speed at 389 mph. I don't know where these statistics came from. Could you perhaps point me to a webpage or reference book with good statistics on the JU-88 G-6 and G-10?

If you can, I promise to climb back in my turret, button down the hatch and not bother you good folks for a while! :lol: :lol:

Hello,

Interesting subject - but I'm somewhat confused about the Ju 88 G-7 now.

I thought I had read in my sources (secondary sources only for this version, though) that the G-7 main difference to the G-6 was the use of the Ju 188 wingtips. Am I wrong there?

I do not really have a firm grasp of the Jumo 213 series, either...
Could perhaps someone sum up the characteristics of the Ju 88 G-7 as known to date. Please name the source of your data - this makes it easier to trace.

Cheers, Azi.

Single recorded loss, but given WNr. this is....
 

more likely a G-1.

Hi,
according to the pros at LEMB,
of the Ju 88 G- series only G-1 and G-6 have been existent.
G-2 to G-5 might have been planned, but have never been built.
Also there are no G-6a to 6-6d or G-7, nore were there any G-10s (built)

So the starting question should be answered: No!

Hi Christian, well, okay, if only the G-1 and G-6 existed, what are the preformance statistics for the G-6 and where did the performance statistics for the other versions come from?

Ju88G-7 with four blade props.
 

Hi!
I'd like this could be an anser for the subject, but I have a question:
Were the Ju88G-7 the only ones with four blades propelles?
Because I've picked-up a photo in the internet of a belly landed Ju88 with those kind of props and I'd like to know if could be the V112, V115 or even a G-7, since it has a badge in the nose.
prototypes.
TIA
All the best

G-7 rambling
 

For Jim P.-IMHO you are correct that W.Nr. 710438 is a G-1. I have other primary source data that indicates that specific a/c was a G-1. Probably a typo.
Ju 88 G-7 sources : 1) No title, no date- Table comparing design and performance parameters of Ju 88 G-6, G-7, Ju 388 & He 219 . 2) Datenblatt 8-88 G-7 (N) mit Fla V, 28.11.44. 3) Strungsmeldung, 31.3.45. There are other sources, but these were pertinent to this discussion. As I indicated in an earlier post, there may be additional information available from a JFM “nostalgia” group in Germany. IIRC , a very nice summary of late Mistel production came from that source (Apparently was not used in the “Mistel” book by Classic).
One of the problems in locating late war production data for JFM Bernberg (the only Ju 88 neubau production center in 1945) is that it was visited by at least three Allied intelligence exploitation groups: USSBS, CIOS and USAAF intelligence. I don’t know who got there first and carried off the data on late production details. The USAAF group was apparently interested in the G-10 Mistels and most of that report deals with them (all the decent drawings and photos of the G-10s come from that visit). The USSBS was interested in bombing effects on production, interviewed the staff, and collected general data on facilities, production and bomb damage. They apparently had no team photographer and there are no photos in their site files (no USSBS report was made on that facility). The third group was the CIOS and they did publish a report with photographs of the factory final assembly and quite a bit of good information. Thus far I have not located the CIOS site files which might have some of the detail information we might be interested in (a CIOS field report of another a/c production site gave RLM W.Nr., SKZ, etc,) or not!

Finally to the G-7 itself. Different documents not only indicate different engine possibilities, but also, different spans. The main difference between the G-6 and G-7 probably would have been the engines. Both the Jumo 213E and DB603 E/F were uprated, high altitude engines. Another feature of the G-7 was to be the Morgensternantenne with Holzkanzel (wooden nose) plus possibly 4 bladed propellors (I can’t seem to find the reference for that item right now), MW 50 and drop tanks for greater endurance. Service ceiling increase over the G-6 was calculated to be 1800 m for the Jumo, not so much for the DB. Vmax (Notleistung+MW 50) at 9.1m altitude was stated to be 627 kph (almost certainly, also a calculated value) with the Jumo 213 E. So, if you find a photo of a Ju 88 with pointy nose, 4 bladed props, drop tanks and long span wings, it just might be a G-7.

I have spent way too much time on this, back to book writing.

Best regards,

Artie Bob

Thank you Artie Bob--Best of Luck on your book!!! I'll be one of the first to pick it up! :D

Glimspur

Of course, at the risk of being a total pain in the a**, I have to point out that we are pretty close to being back to square one. It seems that the G-7 didn't exist. So, the question for me becomes, what were the performance characteristics of the G-6?

Aders on Ju 88G-7
 

Although this information isn’t new, here’s what I found on the Ju 88G-7 in the English edition of “History of the German Night Fighter Force 1917-1945”, page 186. Summarizing:

“…fitted with more powerful Jumo 213 engine, it also had the pointed wingtips of the Ju 188/388 series, as specifically stated in an RLM aircraft type manual. Only about 10-12 Ju 88G-7s were completed in November 1944 and none were ever delivered to an operational unit…Plans for large scale series production were shelved because the performance of this version did not show any notable improvement over that of the current Ju 88G-6 series”

In an appendix, Aders gives performance as:
Max Speed: 584 km/h @ 9,000 m
Range: 2,220 km
Ceiling: 9,800 m.
