Defense Secretary Pete Hegseth intensified his overhaul of the military leadership on Wednesday, forcing the immediate departure of Navy Secretary John Phelan. The move comes as the U.S. Navy maintains a high-stakes blockade of Iranian ports and navigates a fragile ceasefire in the Middle East.
Pentagon spokesman Sean Parnell confirmed Phelan’s exit in a brief statement, noting it was effective immediately. While the official statement offered no specific cause, internal reports suggest Phelan was given a “resign or be fired” ultimatum following months of friction with Hegseth and Deputy Defense Secretary Steve Feinberg.
Friction Over Shipbuilding and Command
Sources familiar with the matter indicate that Phelan, a wealthy financier and Republican donor with no prior military experience, clashed with senior leadership over the pace of naval modernization. Specifically, Pentagon officials viewed Phelan as “reluctant” to accelerate shipbuilding programs—a cornerstone of the administration’s maritime strategy.
Furthermore, officials accused Phelan of failing to adhere to the formal chain of command. These internal disputes culminated in a decision, approved by President Donald Trump, to replace the civilian head of the Navy at a critical operational juncture.
A Pattern of Leadership Upheaval
Phelan’s departure marks the latest in a series of aggressive leadership changes under Secretary Hegseth. Since taking office, Hegseth has removed several high-ranking officials, including the Army’s top officer, General Randy George. This rapid turnover signals a broader effort to install leaders more closely aligned with the administration’s aggressive reform agenda.
Acting Secretary Hung Cao Takes Helm
Undersecretary Hung Cao, a 25-year Navy veteran and former Republican congressional candidate, will serve as acting secretary. Unlike Phelan, Cao possesses extensive combat experience, though his transition into political life has been marked by controversy.
During his unsuccessful 2024 Senate bid in Virginia, Cao drew sharp criticism for:
- Claiming that a decline in Christianity was linked to the rise of “witchcraft.”
- Advocating for a military focused on “alpha males and alpha females” while criticizing inclusive recruiting efforts.
- Facing scrutiny over the accuracy of his claims regarding combat wounds and decorations, though he continues to dispute those reports.
Strategic Implications
The leadership vacuum at the top of the Navy occurs while the service is currently enforcing a worldwide blockade of vessels linked to Tehran. Phelan’s final public appearance, just one day prior at the Sea-Air-Space conference, gave no hint of his exit. During those remarks, he focused on the 2027 defense budget and vessel production—priorities that his successors will now be tasked with executing under Hegseth’s direct supervision.
