US CIC reports of May/June 1945 Linz Austria Bergkristal and Kellerbau Underground instellations (U.S. Army Corps of Engineers)

To Whom It May Concern:

Pursuant to the Freedom of Information Act, I hereby request the following records:

In may 1945 the 3rd US ARMY took the Austrian City of Linz. In the outskirts of the city 2 large underground tunnel complexes were found. One labelled BERGKRISTAL and one KELLERBAU. both constructed and under command of SS General Dr. Ing. Hans Kammler (at times misspelled in the archive files) . Immediately upon liberation of these, all machinery, production and research in these were labelled, cataloged and photographed. And the tunnels were surveyed and photographed also. Reports were made containing all this information and photographs. I request these reports with all attachments. Some have been done my CIC and some by the Army Engineers possibly ALSOS team members. All reports were initially classified.

Machinery and technology were removed prior to the handover to the Russian Army, I also request a report of what was taken by the US ARMY.

Furthermore all interrogations and reports with respect to these two underground systems I request.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 20 business days, as the statute requires.

Sincerely,

Tino Von Struckmann

Good afternoon

I have to say it is absolutely inconceivable the corps or Engineers did not survey this facility. After the war ended they hired the construction engineer and he worked in the US based on his experiences of constructing this and other tunnel systems.
And here on the National Archives search a few photos does come up, however the ones I can find were listed under the Air-force (they made Jet fighters in these tunnels during the war, among other things)
This was a top secret and highly classified site by both the Germans and for the US, It is conceivable the reports and photos from there were classified for a long time, however these reports were made and everything was documented extremely well. From time to time a photo or a document come out.

So is it possibly to look using different searches, names or terms, it is a fact these reports and photos were taken - I however do not know where they are currently housed, or what agency took charge of them after the CIC is there a way we can dig a little deeper please? This is extremely important for modern history, and they be made available for release by now its been 76 years.

Sincerely

SSG Tino Struckmann
