In the span of one dramatic day, the U.S. Navy’s top civilian leadership changed hands. Yesterday, Secretary John C. Phelan departed the Trump administration effective immediately. Stepping into the role as Acting Secretary of the Navy is Hung Cao, a retired Navy captain, combat veteran, and former Vietnamese refugee whose life story reads like a quintessential American comeback.
At 54, Cao now oversees the Department of the Navy: nearly one million sailors, Marines, and civilians, plus a budget topping $250 billion. As the chief operating and management officer since his confirmation as Under Secretary in October 2025, he already knew the inner workings of the massive enterprise. Now he leads it during a period of heightened global tensions, including naval operations tied to the Strait of Hormuz and broader Middle East challenges.
A Journey Born in Turmoil
Hung Cao was born on August 3, 1971, in Saigon, South Vietnam. Just four years later, as communist forces overran the city in 1975, his family joined the frantic exodus of refugees. They were processed through Guam before reaching American shores, arriving with almost nothing.
His father, Quan Cao, had served in South Vietnam’s Ministry of Agriculture and later worked as a USAID agricultural specialist in Niger, West Africa. The family spent several years there before returning to the United States when Hung was about 12. They settled in Northern Virginia, where young Hung learned English, embraced his new home, and excelled academically. He graduated with the very first class of the elite Thomas Jefferson High School for Science and Technology in Fairfax County, a launchpad that helped shape his disciplined, high-achieving path.
Cao has often shared the raw reality of that beginning: “We came to this country with NOTHING. We asked nothing from this country.” His message to fellow immigrants is direct and unapologetic, drawn from personal experience:
“Don’t come to this country and ask for the American DREAM if you’re not willing to obey the American LAWS and embrace the American CULTURE!”
It’s a philosophy rooted in gratitude, self-reliance, and full assimilation — themes that have defined his public voice.
