In brief
US Navy Secretary John Phelan's resignation has been announced by the Pentagon, effective immediately. Undersecretary Hung Cao will serve as acting secretary in the interim. Phelan's departure adds to a series of high-ranking military resignations amidst ongoing conflicts involving Iran and the Strait of Hormuz. The Pentagon expressed gratitude for Phelan's service, although no reason has been provided for his exit.
US Navy Secretary John Phelan is leaving the Trump administration, as confirmed by the Pentagon. His departure is effective immediately, according to Pentagon spokesman Sean Parnell.
Navy Undersecretary Hung Cao will serve as the acting secretary following Phelan's exit, which comes amidst rising tensions over the ongoing US-Israel conflict with Iran and the blockade of the Strait of Hormuz.
Parnell acknowledged Phelan's contributions, stating, On behalf of the Secretary of War and Deputy Secretary of War, we are grateful to Secretary Phelan for his service to the Department and the United States Navy. We wish him well in his future endeavors. However, the Navy did not provide a rationale for his sudden resignation.
Phelan's exit is part of a trend of high-profile departures within the military, following Defense Secretary Pete Hegseth's recent request for Army Chief of Staff Randy George to step down, as well as the removal of other senior army officials.
Since assuming office, Hegseth has made significant changes to military leadership, dismissing over a dozen senior officials including the chief of naval operations and the Air Force's vice chief of staff.
The Secretary of the Navy role, primarily administrative, involves policy formulation, recruitment, training, and logistics related to the Navy's operations. Phelan, a civilian with a background in business rather than military service, was appointed by Trump and sworn in as Secretary of the Navy in March 2025.
He notably supported Trump's announcement of the US Navy's new \u201cGolden Fleet\u201d, which includes battleships named after the former president, reflecting his close ties within the administration.
As tensions in the Strait of Hormuz escalate, the White House maintains that the US will continue its blockade on Iranian ports, with recent clashes reported in the region. The Iranian government, meanwhile, claims that negotiations for reopening the Strait have been compromised due to violations of a ceasefire.
