“Secretary of the Navy John C. Phelan is departing the administration, effective immediately,” Pentagon spokesman Sean Parnell posted on X Wednesday, announcing a sudden leadership change as the Navy conducts an unprecedented blockade of Iranian ports.
Pentagon notice and succession: Parnell names Hung Cao acting secretary
The Pentagon’s abrupt announcement, delivered by Sean Parnell on X, said John Phelan was leaving “effective immediately.” Parnell added, “On behalf of the Secretary of War and Deputy Secretary of War, we are grateful to Secretary Phelan for his service to the Department and the United States Navy. We wish him well in his future endeavors.” The department named Undersecretary Hung Cao — identified in the release as a former Navy diver and a prior Republican congressional candidate — to serve as acting Navy Secretary.
Timing: Sea-Air-Space conference and a Navy budget reveal
Phelan, a businessman with no prior naval experience who had served in the job for just over a year, addressed reporters Tuesday at the Navy League’s Sea-Air-Space conference as the service unveiled a $378 billion budget request. In a Tuesday press release Phelan described the proposal as focused on long-term capability: “This is a strategy-driven budget,” he said. “It's not about business as usual—it's about making generational investments in real, usable capability for our warfighters.”
Budget specifics: the ‘Golden Fleet’ and ship buys
The plan Phelan touted centers on what the Navy is labeling the “Golden Fleet” initiative. The request seeks $378 billion overall and specifically calls for procurement of 18 battle force ships and 16 auxiliary ships as part of that effort. The budget presentation at Sea-Air-Space was the public setting for Phelan’s remarks the day before his departure was announced.
Controversies cited: foreign shipyards and a past flight manifest
Observers highlighted two contentious elements in the hours after the announcement. Hunter Stires, who served as maritime strategist to Phelan’s predecessor, criticized comments Phelan made at Sea-Air-Space suggesting foreign shipyards might build U.S. warships. “Secretary Phelan committed a grave strategic as well as political error yesterday in signaling his openness to outsourcing production of U.S. Navy warships abroad,” Stires said in a statement, arguing the remarks “directly undercut a bipartisan strategy … to incentivize world class allied shipbuilders to invest in modernizing and expanding shipyards here in the United States.” Stires added that Phelan’s removal within hours of that statement “should be read as a stark and welcome signal that outsourcing U.S. Naval construction abroad is and must remain a non-starter.”
Separately, the reporting notes earlier media coverage: in early February CNN first reported that Phelan had flown on a plane from London to New York with convicted sex offender Jeffery Epstein in 2006. Defense One reviewed a copy of the flight manifest that showed six redacted names of other passengers.
Internal reactions at the Pentagon and among retired leaders
One defense insider told Defense One that Phelan’s vision for the service and his personality “clashed with other Pentagon officials,” saying, “Long-rumored but still, wow,” and, “Insiders did not see him a minute past July 4 and even this late was borrowed time.” Retired Navy Rear Adm. Mark Montgomery, a senior fellow at the Foundation for Defense of Democracies, offered a sharp assessment: “Not knowing why he left, I’m careful to not be too critical. But I would just tell you he was not a successful service secretary,” Montgomery said, singling out Phelan’s battleship and frigate initiatives. “Way too many of his good ideas haven’t developed enough and his bad ideas are hurting the force.”
What this means for the Navy, Pentagon officials, and allied shipbuilders
- Navy: With Undersecretary Hung Cao stepping in as acting secretary, the service will move forward under interim civilian leadership while the department adjusts to an abrupt personnel change amid an active naval operation described in reporting as an unprecedented blockade of Iranian ports.
- Pentagon officials: The departure follows a period of reported personnel friction at senior levels, including recent pressure involving Defense Secretary Pete Hegseth and Army Chief of Staff Gen. Randy George, and may prompt renewed internal alignment around procurement and public messaging.
- Allied shipbuilders and domestic yards: Comments attributed to Phelan about potential foreign construction of U.S. warships drew immediate criticism; those debates are likely to influence procurement rhetoric, political pushback, and any plans tied to the “Golden Fleet” production strategy.
The Pentagon did not immediately provide further detail about the reasons for Phelan’s departure, and the White House and a Pentagon spokesman did not immediately return a request for comment. As the Navy rolls out a $378 billion proposal and participates in a reported blockade of Iranian ports, the rapid personnel turnover raises practical questions about who will steer these priorities in the near term and how quickly the department will move to stabilize civilian leadership for the service.
