Navy Secretary John Phelan resigns; Hung Cao to serve as acting head

Surprise Shakeup as Navy Secretary John Phelan Steps Down

In a sudden move that has stirred the Pentagon’s leadership ranks, Navy Secretary John Phelan has left his post. The announcement, made on Wednesday, marks the first departure of a military service head during President Trump’s second term. This exit adds to a pattern of changes among top defense officials.

The reasons for Phelan’s unexpected resignation remain unclear. His departure coincides with the Navy’s strategic operations, including a blockade of Iranian ports amid a fragile ceasefire. Stepping in as acting head is Hung Cao, a seasoned Navy combat veteran and former political candidate in Virginia.

Pentagon Leadership Changes Under Scrutiny

Phelan’s exit follows a series of high-profile dismissals by Defense Secretary Pete Hegseth, who recently removed the Army’s top officer, Gen. Randy George. These changes have been ongoing since February 2025, affecting various military branches and top leaders, including Adm. Lisa Franchetti and Gen. Jim Slife.

The abrupt nature of Phelan’s departure was underscored by his recent engagements, including a speech at the Navy’s annual conference and discussions on the Navy’s budget with House Armed Services Committee leaders.

Phelan: A Trump Ally with Business Background

Phelan, a significant donor to Trump’s campaign, was a newcomer to military leadership. His background includes founding the investment firm Rugger Management LLC and advising the Spirit of America nonprofit. Despite his civilian status, Phelan had been tasked with invigorating the Navy.

Efforts to reach Phelan for comment were unsuccessful, and the White House directed inquiries to a statement from Pentagon spokesman Sean Parnell. Parnell’s post on X confirmed Phelan’s immediate departure.

Strategic Navy Deployments During Leadership Transition

Phelan’s resignation comes amidst pivotal Navy operations. The service currently has three aircraft carriers in or en route to the Middle East, with U.S. forces on standby for potential combat operations against Iran. Concurrently, the Navy is actively involved in anti-drug operations in the Caribbean.

Cao’s Path to Acting Navy Secretary

Hung Cao, who assumes the role of acting Navy secretary, previously pursued political office with Trump’s backing. Despite unsuccessful bids for the U.S. Senate and House, Cao’s military career includes serving with SEAL teams and special forces in challenging environments like Iraq and Afghanistan.

In public forums, Cao has critiqued military policies, including COVID-19 vaccine mandates and diversity efforts. His stance reflects broader themes in Trump’s administration, which has taken a firm position against DEI initiatives.

Cao’s educational credentials are notable, with degrees from the U.S. Naval Academy and advanced studies at prestigious institutions like MIT and Harvard. As undersecretary, he has advocated for reinstating service members impacted by vaccine mandates.
