US Navy Secretary John Phelan has resigned from his position in the Trump administration, with his departure taking effect immediately, as announced by the Pentagon. Navy Undersecretary Hung Cao will temporarily assume the role. Phelan’s exit is the latest in a series of high-ranking military departures, occurring amidst tensions related to the US-Israel conflict with Iran and the ongoing blockade of the Strait of Hormuz. Although the Navy has not disclosed a specific reason for Phelan’s resignation, reports suggest it may be linked to disagreements over shipbuilding policies. Phelan, a civilian and major donor to Trump’s campaign, was appointed in March 2025 and had supported Trump’s initiative to commission a new series of Navy battleships. His departure follows a pattern of dismissals by US Defense Secretary Pete Hegseth, who has removed several senior military officers since taking office. The role of Navy Secretary involves administrative duties such as policy formulation, recruitment, and overseeing naval logistics. Phelan’s replacement, Cao, is expected to continue these responsibilities on an interim basis.
