The following is an excerpt from a previously classified letter written by Admiral Robert Dennison (CINCLANTFLT, 1960-1963) to Lieutenant General Gordon A. Blake (DIRNSA, 1962-1965) on 17 November 1962 regarding the contribution of SIGINT during the Cuban Missile Crisis.

“I should like to take this opportunity to mention the very significant contribution which SIGINT in general – and the National Security Agency in particular – have made toward support of Atlantic Command.  The unique and vital intelligence made available as a result of the national SIGINT effort frequently finds its end use and final justification at the level of the Unified Commander.  In the present situation SIGINT has been one of the most important single factors in supporting our operations and improving our readiness.  Your fine support is much appreciated.”

DIRNSA responded:  “While you mentioned NSA in particular…the Naval Security Group…deserve[s] a lion’s share of the credit for their work in the fields of collection and direct processing to our customers.  I have taken the liberty of passing on your kind remarks to both NSA personnel and the Service Cryptologic Agencies as kindred elements of our SIGINT team.”
