In Memoriam: Rear Admiral Danelle M. Barrett, USN (Ret.)

Aug. 28, 2024 | By Sam Cox (Rear Adm. USN, Ret.), Director, Naval History and Heritage Command
It is with deep regret I inform you of the passing of Rear Admiral (lower half) Danelle Marie Barrett on 26 August 2024 at age 57. Rear Admiral Barrett entered the Naval Reserve Officer Training Corps (NROTC) at Boston University and was commissioned an ensign in August 1989, serving as an information professional until her retirement in October 2019 as the director of the Navy Cyber Security Division in the Office of the Chief of Naval Operations (OPNAV).

After retiring from active duty she engaged in consulting, public speaking, and writing, and she was on the corporate boards of KVH Industries and the Protego Trust Company.

Whenever junior intelligence officers would complain about how hard things were, I would tell them to try living in the N6’s world for a new definition of pain. Well, Danelle lived in that world for her entire career and thrived in it, earning a stellar reputation for being able to make command and control, communications, combat systems, and cyber work whenever and wherever needed. She did it all: Navy C3 ashore, deployed afloat, and overseas; Joint C3; NATO C3; and multi-national C3 in a war zone (Iraq). Besides technical prowess, she displayed extraordinary leadership, starting as an ensign in charge of a telecommunications facility and continuing through command of the largest computer telecommunications master area station in the Navy. She was an innovator, implementing visionary digital transformation to modernize with unprecedented speed, significantly improving Navy information warfare capabilities. Somehow through it all she managed to earn four master’s degrees and numerous accolades. She finished as one of DoD’s leading cyber experts at Fleet Cyber and then at U.S. Cyber Command (in a position normally held by an information warfare officer—and formerly held by cryptologists), using some of the most sensitive intelligence in an extremely fast-paced warfare area. In the end, she lost a battle with a rare form of brain cancer, but she fought it with dignity, courage, and a fighting spirit that should inspire any warfighter and will no doubt help the medical profession devise better treatments. Several flag officers offered to write Danelle’s obituary if I didn’t have time—that is how much she was respected in the information warfare community, where she had earned near-legendary status. We, along with the rest of the Navy, mourn the passing of this officer taken from our wardroom far too early and express our gratitude and condolences to her family for the immense sacrifices they made that enabled Danelle to serve our country so well.

Rest in Peace, Admiral Barrett
