Navy Secretary Transition at the Pentagon

The Pentagon recently announced a significant change in its civilian leadership, with Navy Secretary John Phelan stepping down immediately. Chief Pentagon Spokesman Sean Parnell confirmed that Under Secretary of the Navy Hung Cao will take over as acting secretary.

This decision comes just a day after Phelan delivered a keynote address at the Sea-Air-Space symposium, where he was advocating for the Trump administration’s vision for a new generation of battleships.

Although the Pentagon’s official statement expressed gratitude for Phelan’s service, it did not provide reasons for his sudden departure. However, reports suggest that this shift follows a wave of notable leadership changes in the Department of War, overseen by Secretary of War Pete Hegseth, who apparently played a role in Phelan’s dismissal.

Sources indicate that Phelan may have been asked to resign due to internal disputes over the speed of naval modernization and the administration’s maritime blockade efforts.

His exit also highlights a second major leadership change in the services within the same month, coming shortly after Army Chief of Staff Gen. Randy George was ousted.

Hung Cao, who now assumes the role of acting secretary, offers a contrasting background compared to Phelan. Unlike Phelan, who had a successful career as a businessman and major political donor with no military experience, Cao is a veteran and retired Navy Captain with over 30 years of active duty.

A Naval Academy graduate and a refugee from South Vietnam, Cao’s military career includes roles as a deep-sea diver and an explosive ordnance disposal (EOD) officer. He notably led the recovery effort for John F. Kennedy Jr.’s remains after his 1999 plane crash and has completed several combat tours in Iraq, Afghanistan, and Somalia.

As he steps into this acting role, Cao faces a Navy amid significant geopolitical challenges and internal changes. Before this appointment, he served as the Navy’s chief management officer, focusing on modernizing the aging IT systems and business operations.

His immediate tasks will likely involve stabilizing leadership within the department and overseeing the development of the “Golden Fleet” initiative, which includes modernizing the fleet with nuclear-armed ships, railguns, and hypersonic missiles. Officials from the Pentagon have indicated that Cao is expected to remain in the acting position until a permanent successor is nominated and confirmed by the Senate.
