Just 24 hours after addressing a room full of sailors, defense executives, and reporters about the future of America’s fleet, Navy Secretary John C. Phelan was out of a job.
Secretary of the Navy John Phelan was ousted from his position Wednesday amid tension with Defense Secretary Pete Hegseth over his implementation of shipbuilding reform and his close relationship with President Donald Trump. Pentagon spokesman Sean Parnell said Phelan would be departing “effective immediately.”
What Triggered the Firing?
Multiple sources told CNN there was tension for months between Phelan and Hegseth, who believed Phelan was moving too slowly on implementing shipbuilding reforms and was also irked by Phelan’s direct communication with Trump, which Hegseth viewed as an attempt to bypass him.
Hegseth felt Phelan had bypassed the chain of command too much with a direct line to Trump, whose Mar-a-Lago Club in Palm Beach is near Phelan’s mansion. Trump, frustrated by slow shipbuilding progress himself, told Hegseth to “take care of it.”
Hegseth sent a message to Phelan informing him he needed to resign or be fired. Phelan, though, did not appear to believe Trump was aware of the message and began phoning White House officials to find out if the president knew.

The Dramatic Moment Phelan Walked Into the West Wing
Phelan came to the White House grounds and went to the West Wing lobby looking for officials. Trump met with him briefly, confirming that Phelan was out of a job. At least two White House staffers had already told Phelan the decision was Trump’s.
The timing could not have been more jarring. Just the day before, Phelan had spoken publicly about the Navy’s future — including plans for a next-generation battleship.
Who Is Hung Cao — The New Acting SECNAV?
Taking over as acting secretary is Hung Cao, who ran a failed US Senate bid in Virginia to try to unseat Democratic Sen. Tim Kaine in 2024. He had Trump’s endorsement in the Republican primary and gave a speech at the 2024 Republican National Convention. Cao’s biography includes fleeing Vietnam with his family as a child in the 1970s.
Cao is a US Naval Academy graduate and was commissioned as a special operations officer, serving as a diver and explosive ordnance technician. During his long career in uniform, he deployed to Iraq and Afghanistan during the post-9/11 wars.
Phelan was the Navy’s 79th service secretary. Cao, as the Navy’s No. 2 civilian, is stepping directly into the SECNAV chair during one of the most operationally intense periods in the Navy’s recent history.
Why the Timing Is Especially Alarming
Phelan is leaving during a busy time for the Navy. It has three aircraft carriers deployed in or heading to the Middle East, while the Trump administration says all the armed forces are poised to resume combat operations against Iran should the ceasefire expire.
Phelan’s abrupt dismissal comes as the sea service continues to grapple with the ongoing conflict with Iran and in the Strait of Hormuz. On Sunday, a US Navy destroyer enforced the naval blockade of Iranian ports when it fired its Mk-45 gun at a cargo vessel attempting to sail toward an Iranian port.
A Pattern of Pentagon Purges Under Hegseth
Phelan’s departure is the latest in a series of shakeups of top leadership at the Pentagon, coming just weeks after Defense Secretary Pete Hegseth fired the Army’s top uniformed officer, Gen. Randy George. The firings began in February 2025, when Hegseth removed Adm. Lisa Franchetti, the Navy’s top uniformed officer, and Gen. Jim Slife, the No. 2 leader at the Air Force. Trump also fired Gen. Charles “CQ” Brown Jr. as chairman of the Joint Chiefs of Staff.
Navy Secretary John Phelan Fired: Phelan’s firing is the first among the military service secretaries appointed under Trump — a line that has now been crossed, with the Navy at war footing and the world watching.
