Ju 87R-2 question

[Hoggardhigh]

Hi all,

Wikipedia's article about the Junkers Ju 87 has the following text about the Ju 87R-2 long range variant: "The Ju 87 R-2 had the same airframe as the B-2, and strengthened to ensure it could withstand dives of 600 km/h (370 mph)." My question is this: were the Ju 87B-2 and R-2 identical to each other apart from the latter's additional internal fuel tankage and drop tanks, as many sources seem to suggest?

Thanks

Basically, yes.

Basically, yes.

What do you mean, "basically, yes"?

 

[Airframes]

Yes, as opposed to no. It was the same airframe as, and derivative of, the B-2, with the addition of the internal tanks, and the provision for underwing tanks.
Haven't seen any details about strengthening, other than what would possibly be required for the internal wing tanks.

What do you mean by, "what would possibly be required for the internal wing tanks"?

No additional fuel tanks in The R-series, just drop tank ability and provision for additional internal oil tank

 

[Airframes]

Dennis has pointed out that there were no internal fuel tanks. However, two of the references I checked mention these. Therefore IF there were internal fuel tanks, then it's possible / probable that the structure in the area of the tanks might have been strengthened to cope with the extra weight.

If you are really in need of an answer, get this book:

Somewhat funny to read through diverse Ju 87 publications. Some stat all Ju 87R had additional 300l of internal fuel, one even claims the R-1 had it but from the R-2 onwards it was dropped again.
The R-1 manual from 3/42 does not mention additional internal fuel tanks at all.

No wonder the manual doesn't mention it because neither R-1 nor R-2 kites had the additional internal fuel tank installed. Both of them based on the B-1 and B-2 variants and had the internal fuel tanks of the standard capacity of 480l. There were added two additional jettisoned fuel tanks, each of 300l, on underwings. And this made the range increased.

Fuel system for R-1 below. The wing tanks are 240l each as Wojtek says:
