Who is Vice Admiral Heidi Berg? She commands U.S. Fleet Cyber Command, U.S. Navy Space Command, Joint Force Headquarters-Cyber (Navy), and U.S. 10th Fleet. In September 2026 she warned that America’s “cyber magazine” of offensive tools is running dry — a striking admission.
Who is Vice Admiral Heidi Berg?
Berg is a U.S. Navy vice admiral with 35 years in the cyber, cryptologic, and space warfighting domains, per her official Navy biography. She graduated from the U.S. Naval Academy in 1991, studied Russian at the Defense Language Institute, and earned a master’s in Middle Eastern Studies from Oxford.
She flew over 1,000 hours in EP-3E aircraft, directed the ISAF Red Team in Kabul (2012), and commanded Navy Information Operations Command Bahrain. As a flag officer she led intelligence (J-2) at U.S. Africa Command and strategy, plans and policy (J-5) at U.S. Cyber Command; in 2021 the President of France made her a Chevalier of the Legion of Honour. Nominated in September 2025, she assumed command — and a third star — in October 2025.
Why she matters
Berg sits at the center of a defining debate: how fast America’s stockpile of “exquisite” cyber capabilities is being consumed by sustained combat — and she owns the force burning through it.
Key positions
Cyber workforce. To DefenseScoop (March 2026): the military would “never be able to truly effectively compete against some of the higher paid cyber workforce that is out in industry” — but the mission itself, under authorities civilians legally cannot, is the military’s value proposition for cyber talent.
The threat picture. At the Naval War College’s Future Warfighting Symposium (August 6, 2026): “We face adversaries who seek to change the global world order… and that is what is at stake. I truly think this is existential.” And: “In cyberspace, and in space, in electronic warfare… we are at war every single day.”
Recent statements: the “cyber magazine” warning
Berg’s most reported remarks came September 24, 2026, at HammerCon 5.0 — the Military Cyber Professionals Association’s conference at Johns Hopkins University’s Applied Physics Laboratory — alongside Army Cyber Command chief Lt. Gen. Christopher Eubank. Per Breaking Defense:
“Your cyber magazine of these exquisite fires is empty pretty damn quick.”
She meant the finite stockpile of pre-built network accesses and exploits — “the abilities to hack and frustrate or turn off key systems in an opposing nation,” as Reuters explained. Her follow-up framed the regeneration problem: how to keep developing “accesses and effects” for a longer sustained conflict against a peer competitor.
The context: cyber operators supported Operation Epic Fury — the U.S.-led operation against Iran begun February 28, 2026 — at a sustained pace, “constant,” in Eubank’s words, “probably for the first time for the cyber force at large.” Berg also called the operation that captured Venezuelan President Nicolas Maduro earlier in 2026, reported as “Absolute Resolve,” “the largest and most complex cyber operation that had ever been executed.”
What to watch next
Can Cyber Command rebuild burned accesses faster than adversaries harden their networks, will funding follow the rhetoric, and can the military keep its operators? See our intel hub and our 2026 maritime extortion explainer.
