“Secretary of the Navy John C. Phelan is departing the administration, effective immediately,” stated Pentagon spokesman Sean Parnell, confirming a significant shift in military leadership that has been characterized by ongoing changes during the Trump administration. Following this announcement, Hung Cao has been appointed as acting Secretary of the Navy, a role that marks a continuation of his service following his previous position as Under Secretary of the Navy.
Cao, who is a retired U.S. Navy captain with 25 years of service, brings a wealth of experience to this new role. He holds both a bachelor’s degree in ocean engineering from the U.S. Naval Academy and a master’s degree in applied physics from the Naval Postgraduate School. His extensive military background includes deployments to Iraq, Afghanistan, and Somalia, which have shaped his understanding of modern naval operations.
In recent years, Cao has also been involved in modernization efforts for the Navy’s IT systems—an area that he has emphasized as critical for maintaining operational effectiveness. He has articulated a vision where service members “deserve the best training and weapons available,” arguing that their intrinsic desire to solve problems using technology should not be stifled by red tape.
However, his appointment comes on the heels of John Phelan’s departure, which was not without controversy. Phelan was known for being a major donor to Trump’s campaign prior to his appointment and had faced scrutiny over various policies during his tenure. The leadership changes at the Pentagon reflect broader shifts within military governance under Trump’s administration and have raised questions about continuity and strategic direction.
Yet, Cao’s political aspirations have not gone unnoticed; he ran unsuccessful campaigns for both the U.S. Senate and House in Virginia during 2022 and 2024. This political involvement may provide him with insights into navigating complex bureaucratic landscapes as he steps into this pivotal role.
Cao has also expressed criticism regarding COVID-19 vaccine mandates for service members and has questioned military diversity initiatives—issues that resonate deeply within segments of military personnel and their families. His comments suggest a willingness to engage in contentious debates that could shape future policies.
As Cao takes on his new responsibilities, it remains to be seen how he will balance traditional naval priorities with modern technological demands. His experience at CACI International in electronic warfare and counter-drone technology adds another layer to his qualifications but also raises expectations regarding innovation within naval operations.
Details remain unconfirmed regarding any further developments or potential appointments within the Pentagon following these changes; however, all eyes will be on how Cao navigates this transition period and what strategic decisions will emerge from his leadership.
