Breaking news from Washington is shaking up the U.S. Navy leadership at a very sensitive moment.
The Pentagon has confirmed that Navy Secretary John Phelan, also mentioned in some internal references as John F. Sullivan, has been removed from his position with immediate effect. The decision reportedly follows growing tension between him and the Secretary of Defense after months of internal disagreements.
In a fast move to fill the gap, Under Secretary Hung Cao has been appointed as the acting head of the Navy. Cao is a U.S. Naval Academy graduate with around 25 years of military service. His background includes combat deployments in Iraq, Afghanistan, and Somalia, giving him deep operational experience at a critical time.
This leadership change is happening while the Navy is reportedly active in high-tension maritime operations in the region, including enforcement activity near Iranian waters and monitoring of shipping routes around the Strait of Hormuz. Reports suggest multiple vessels have been turned back and some inspections have taken place, adding to the already sensitive situation at sea.
The timing of the shake-up is raising eyebrows inside defense circles. A major leadership switch during ongoing naval operations is rare and often signals deeper disagreements within the chain of command. Phelan’s exit is also notable because of his close political connections and role as a prominent fundraiser before taking office.
Hung Cao now steps into a high-pressure role where stability and quick decision-making will be essential. With the fleet already in motion and global attention on the region, all eyes are on how the new acting secretary manages continuity and command during this unsettled moment.
For now, the Pentagon is staying quiet on further details, but this sudden change has already sparked questions about internal friction at the highest levels of U.S. military leadership.
