US Naval Technical Mission - Japan & Germany

US Naval Technical Mission to Japan documents. The photographs included in NDL online presentation of the documents are actually scanned pages from the "Summary Report" of the Naval Technical Mission.
You can order microfilm copies of this "Summary Report" (and other mission reports) at http://www.history.navy.mil/branches/dupform.htm.
However, the photos posted online will reproduce much better than the microfilm copies.

We believe the archival location for other photos included in the various reports of this mission is at the National Archives and Records Administration http://www.archives.gov/welcome/index.html in College Park, Maryland, USA http://www.archives.gov/facilities/md/archives_2.html. You should contact the National Archives http://www.archives.gov/global_pages/inquire_form.html about obtaining copies of such photos. The photos, if available, are most likely held in the Still Picture Branch of the National Archives:

Concerning a similar project which may have investigated the Germany naval forces, there is the Naval Technical Mission to Europe.
