US Navy Secretary John Phelan has left his position effective immediately, with Undersecretary Hung Cao stepping in as acting chief, marking the latest high-level departure amid a broader Pentagon leadership reshuffle during escalating global tensions.
John Phelan served as US Navy Secretary from 2025 until his sudden departure in 2026.
US Navy Secretary John Phelan has abruptly departed his role, the Pentagon confirmed, with the move taking immediate effect and no official reason provided. The sudden exit comes as part of a wider shakeup within the US Department of Defense, where several top military leaders have recently been removed or replaced.
The US Navy remains central to operations amid rising tensions in the Middle East.
Hung Cao, the Navy’s undersecretary and a veteran of more than two decades of military service, has assumed the position in an acting capacity. Officials offered limited details about the circumstances surrounding Phelan’s departure, though reports suggest internal tensions and leadership disagreements may have contributed to the decision.
The Pentagon has overseen multiple leadership changes in recent weeks.
The leadership change comes at a critical moment, with the US Navy playing a central role in ongoing operations linked to rising tensions with Iran, including enforcement of a naval blockade. Analysts say the sudden transition at the top of the Navy adds another layer of uncertainty to an already volatile geopolitical environment.
