NSA Acronyms

The second document in this file is the recently unclassified "Guide to Historical Cryptologic Acronyms and Abbreviations, 1940-1980," from the NSA

Note that there are still some redactions.

MUSIC Multi-user Special Intelligence Center

So MTV is a tv program for people of special intelligence?

Puzzled as to the point of declassifying a document but then redacting a bunch of stuff. Seems simpler to just leave it classified, or at most downgrade it?

Isn't the situation as follows: Ddeclassification after X years required by law - however redacting is still possible (in sensible amounts)

I'm not from the US, but I guess that's a likely explanation...?

I'm puzzled as to why a bunch of acronyms needed to be classified in the first place.

BFO - Beat Frequency Oscillator, any ham or SW listener knows what that is.

STANCICC State-Army-Navy Communications Intelligence Coordinating Committee (huh?)

Re: "Puzzled as to the point of declassifying a document but then redacting a bunch of stuff."

It was redacted first, then the redacted version was declassified.

The most boring 73-pages I've read in quite a while. It would actually have made sense for them to differentiate between meaningful acronyms and n-letter abbreviations of agencies, organisations, departments, divisions, groups and so on and so forth. With so many of them, one cannot help but wonder how these guys in the military-intelligence industry ever manage to get anything done. Hey, wait a minute ...

Most silly: KORCOM - Korean communist
Most prominently missing: AA - Acronym addiction

GOT Gulf of Tonkin - that's mildly unsettling.

TRRS Two Rock Ranch Station, Petaluma, CA. NSA was in Marin County? No wonder they cost so much.
It's a Coast Guard training center now.

There's lots of talk in private sector about creating "culture of security" in addition to technologies. Guess it starts with lots of acronyms and denoting their specialness.

@Dan, thanks, the timeline was kinda interesting.

One thing that caught my eye in the timeline was that the US was intercepting Japanese PURPLE codes 1-2 years before Pearl Harbor. Not news, but I hadn't ran across that little factoid before.

And there was me expecting a light-hearted piece on humourous translations of "NSA", to which I might have commented "Needless Spending in Abundance".

Never mind...

@GregW: David Kahn, in 'The Code Breakers', describes how the 13-part ultimatum to be delivered to the US State Dept by the Japanese Embassy in Washington, on the morning of December 7, 1941, was decoded from Purple, translated and delivered to State by the US Navy cryptanalytic service hours before the Japanese version was received. This was a result of years of work attacking Purple.
