Subject: 80th Anniversary of Navy Cryptology
As many of you know, March 11, 1935 is observed as the birth of Navy cryptology/IW with the standup of the Communications Security Group, which was later renamed the Naval Security Group (NSG). Navy’s cryptologic roots of course go back to the On the Roof Gang in 1928 and earlier, but it is this day that directly links to NSG and that we have marked over the years.
Fleet Cyber Command is built on a rich heritage of those who came before us, including the Naval Security Group, Naval Network Warfare Command, Naval Computer and Telecommunications Command and Navy Space Command. I believe the heritage and commitment to excellence born in these original organizations continues to shape who we are today. You make me proud to serve at the helm, and I believe we will continue to make our predecessors proud moving forward.
With respect to Navy cryptology/IW specifically, our Navy and our country have a storied history of code breaking in defense of the nation and today’s team of professionals proudly and skillfully carries on that legacy. Thank you for all you do as you continue to conduct tailored Signals Intelligence and deliver excellence across all of our strategic goals.
