A.
Actions Taken by NSA to Locate Information Related
to the 
Assassination of President Kennedy
Over the past fourteen and one-half years, NSA has
performed 
a 
number of separate in-depth reviews of materials in
its files in an 
attempt to isolate data that might be relevant
to the assassination 
of President Kennedy. Nothing of significance
has been determined as a result 
of those reviews.
1. November-December 1963 Immediately after the
assassination
, 
NSAinitiated a large-scale manual and machine
review of 
available SIGINT, including all U.S./Cuba traffic (NSA
intercepted messages 
at an average of 1,000 per day at that time).
À computer search was 
initiated using Oswald's name as the minimum
for research criteria. 
Additionally, all traffic between Cuba/New
Orleans and Cuba/Dallas 
was manually reviewed (an analyst involved
recalled that 25 to 50 
analysts reviewed the traffic manually,
along with traffic 
from Cuba and some Soviet traffic).
during 
the search, items from the Oswald address book provided by

search criteria.

on the basis of 
other Warren Commission requests made informally
by Allen Dulles.

Governmental Operations with Respect to Intelligence Activities (SSC)
In response to an SSC request on the Assassination,
NSA reviewed its 
Soviet 
and Cuban files, including Cuban military.
