President Donald Trump has nominated Hung Cao, a retired Navy captain and vocal supporter, to serve as the permanent Secretary of the Navy. The announcement, made on Tuesday, ends weeks of speculation about who would fill the role on a permanent basis after John Phelan departed the position unexpectedly in late April. Cao has been serving as acting Navy secretary since Phelan's exit, and his elevation signals a preference for political loyalty and military experience in one of the Pentagon's most significant civilian posts.
The nomination arrives at a moment of intense scrutiny over civilian leadership in the armed forces. The Navy faces a host of challenges, from shipbuilding delays and recruitment shortfalls to strategic competition in the Indo-Pacific. Cao's supporters argue that his 25-year naval career, which included combat tours in Iraq and Afghanistan, gives him a unique understanding of the fleet's needs. Critics, however, point to his relatively thin management background and his history of partisan commentary as potential liabilities for a role that traditionally demands nonpartisan stewardship.
Who Is Hung Cao?
Hung Cao immigrated to the United States from Vietnam as a child, fleeing the aftermath of the Vietnam War. His family's journey from refugee to American military service is a central part of his personal narrative, one he has frequently invoked in public appearances and political campaigns. Cao graduated from the United States Naval Academy and served as a surface warfare officer, eventually commanding a guided-missile destroyer. He deployed multiple times to the Middle East and later worked in the Pentagon and at the National Reconnaissance Office.
After retiring from active duty in 2021, Cao entered politics. He ran for Congress in Virginia's 10th District in 2022, losing to incumbent Democrat Jennifer Wexton. He mounted a U.S. Senate campaign in 2024, challenging incumbent Tim Kaine. Cao lost that race by a significant margin, but his campaign attracted national attention for its combative style and his unwavering support for Trump's agenda. His political profile, combined with his military credentials, made him an attractive candidate for a defense post in the new administration.
From Acting to Permanent: The Path to Nomination
Cao took over as acting Navy secretary in early May, filling a vacancy created by John Phelan's abrupt resignation. Phelan, a businessman with no prior military experience, had served only a few months before stepping down without a formal explanation. The sudden departure left the Navy's top civilian office in flux and fueled concerns about instability in defense leadership. Cao's appointment as acting secretary was seen as a stopgap measure, but his performance during the interim period appears to have satisfied the White House.
According to two senior administration officials who spoke on condition of anonymity to discuss personnel matters, Trump was impressed by Cao's handling of several high-profile issues, including the Navy's response to a collision involving a destroyer in the South China Sea and his public defense of the administration's shipbuilding budget. The officials said Trump viewed Cao as a loyalist who could be trusted to advance the president's defense priorities without bureaucratic resistance.
The nomination now moves to the Senate Armed Services Committee, where Cao is expected to face questions about his qualifications and his political activities. Democratic senators have already signaled they will press him on his past statements criticizing diversity initiatives in the military and his support for reducing the Navy's focus on climate change adaptation. Republican senators, however, have largely rallied behind the pick, praising his service record and his commitment to rebuilding the fleet.
Political Loyalty vs. Institutional Expertise
The choice of Cao underscores a broader pattern in Trump's defense appointments: a preference for individuals who have demonstrated personal loyalty to the president over those with deep experience in Pentagon bureaucracy. This approach has its defenders, who argue that the military needs civilian leaders willing to challenge entrenched interests and push for reform. But it also raises concerns about the erosion of norms that have historically kept the military insulated from partisan politics.
Retired Admiral James Stavridis, a former NATO supreme allied commander, offered a measured assessment. "Captain Cao brings real operational experience to the table, which is valuable," Stavridis said in an interview. "But the Secretary of the Navy must also be a skilled manager of a massive enterprise, a deft navigator of interagency politics, and a credible voice on Capitol Hill. Those are different skill sets."
Cao's supporters counter that his combat experience and his time as a Navy captain give him an intuitive understanding of what sailors and their families need. They point to his advocacy for improved housing, better mental health services, and faster maintenance cycles as evidence of his commitment to the force. His critics, however, note that he has never managed an organization of the Navy's size or complexity, and that his political rhetoric could undermine morale among a diverse force.
Key Challenges Facing the Navy
Whoever leads the Navy on a permanent basis will confront a daunting list of problems. The fleet has shrunk to fewer than 300 ships, far below the 355-ship goal set by Congress. Shipbuilding programs are years behind schedule and billions over budget. The Columbia-class submarine program, essential to the nuclear deterrent, is facing cost overruns that threaten to consume the Navy's entire shipbuilding budget. Cao has acknowledged these challenges and has promised to prioritize accelerating shipbuilding and improving fleet readiness.
Recruitment is another persistent headache. The Navy missed its enlistment goals in 2023 and 2024, and while recent figures show modest improvement, the service continues to struggle to attract young Americans. Cao has advocated for expanding recruiting incentives, reducing administrative burdens on recruiters, and reviving programs that allow high school graduates to enlist without a GED. Whether these measures will be sufficient remains to be seen.
Strategic competition with China looms over all of these issues. The Navy's presence in the Indo-Pacific is strained by high operational tempo and aging infrastructure. Cao has been a vocal proponent of increasing naval presence in the region and has called for more aggressive freedom-of-navigation operations. His hawkish stance aligns with the administration's broader posture but could escalate tensions with Beijing.
Reactions on Capitol Hill
The nomination has drawn sharply partisan reactions. Senator Roger Wicker, the Republican chairman of the Armed Services Committee, praised Cao as "a proven leader who understands the demands of modern naval warfare." Wicker said he expects a swift confirmation process. Senator Jack Reed, the committee's ranking Democrat, was more cautious. "We need a Secretary of the Navy who can manage budgets, inspire the force, and maintain the trust of our allies," Reed said. "I look forward to examining Captain Cao's record in detail."
House Democrats, meanwhile, have seized on Cao's past political statements. Representative Adam Smith, the ranking member of the House Armed Services Committee, released a statement calling Cao "a partisan activist who has shown contempt for the very diversity that makes our military strong." Smith was referring to comments Cao made during his Senate campaign, in which he criticized what he called "woke ideology" in the armed forces.
Veterans' groups have offered mixed reactions. The Veterans of Foreign Wars issued a neutral statement welcoming "a fellow veteran to this important role" and urging the Senate to conduct a thorough review. The Iraq and Afghanistan Veterans of America declined to comment, citing its policy of not weighing in on nominations.
What Comes Next
Cao's nomination will likely be scheduled for a confirmation hearing in the coming weeks. He can expect tough questioning from Democrats on his political activities, his management experience, and his views on military diversity and climate change. Republicans will likely focus on his service record and his plans for the fleet. The outcome is not in serious doubt, given the Republican majority in the Senate, but the hearing could provide a platform for broader debates about civilian control of the military and the role of politics in defense appointments.
In the meantime, Cao will continue to serve as acting secretary, overseeing day-to-day operations and preparing the Navy's budget request for the next fiscal year. His performance in that interim role may influence the confirmation process, as senators weigh his handling of ongoing crises against his political background. For now, the Navy faces a period of uncertainty at the top, even as the strategic environment demands steady leadership.
