A collection of National Security Agency (NSA) field reports, finished reports, studies, summary reports, memoranda, watch officers' notes, and analyst communications related to Vietnam War and Southeast Asia POW/MIA cases. Some material remained secret until September 2014.
On July 13, 1992, the Senate Select Committee on POW/MIA Affairs requested that the NSA review its records for information and signal intelligence related unresolved POW/MIA cases.
The Senate Select Committee on POW/MIA Affairs was a special committee created by the United States Senate in 1989, to investigate Vietnam War era United States service personnel still listed as missing in action. The committee was in existence from August 2, 1991 to January 2, 1993.
Highlights from the collection include:
A 1996 NSA special study, SIGNIT Report "NSA SIGINT Correlation Study - POW/MIA." This signal intelligence (SIGINT) correlation study was the result of a five-year effort by the NSA staff to correlate all available Vietnam War-era SIGINT to specific Vietnam War Prisoner of War/Missing in Action (POW/MIA) cases.
A 1992 report, "B51 Technical SIGINT Report 002-92 NSA SIGINT Correlation Study - POW MIA." This SIGINT correlation study is an NSA analytical working aid attempting to correlate all available Vietnam War era SIGINT to specific POW/MIA cases. The correlations are based on NSA field site reporting, NSA end product and summary reporting, US forces summaries introduced into SIGINTJ reporting channels, and (SIGINT) reporting.
Below is an NSA signal intelligence intercept report on communications conducted by the North Vietnamese Army's 16th Anti-Aircraft Artillery (AAA) Battalion. The communications regard actions of the NVA in the crash site area of a plane flown by Lt Cmdr. Michael George Hoff, his status as of January 2015 is MIA. His bio can be found at P.O.W Network Website http://www.pownetwork.org/bios/h/h117.htm
