New Releases from the National Declassification Center

The National Declassification Center at the National Archives yesterday announced the availability of 240 sets of records that have recently undergone declassification processing.

Many of the record collections are listed in such banal or generic terms that it is hard to imagine they would attract any interest at all. (“Bureau of Naval Personnel Activity File, Personnel Accounting Ledger Records, 1952-1967”?)

But there are also a few items that will make at least some researchers’ hearts beat a little faster, such as three boxes of declassified “Cloud Gap Field Test Reports, 1962-69.”

Cloud Gap was an ambitious government project in the 1960s to establish the technical basis for new arms control measures. Previously disclosed Cloud Gap Field Test Reports on the verifiable dismantlement of nuclear weapons are posted here.
