Navy Secretary John Phelan Departing Amid Iran Blockade Navy Secretary John Phelan is leaving the Trump administration effective immediately, the Pentagon announced on Wednesday, April 22, 2026. His departure comes as the U.S. Navy enforces a high-stakes blockade of Iranian ports near the Strait of Hormuz. Hung Cao, the Under Secretary of the Navy, will lead the military branch in an acting capacity, according to Pentagon spokesperson Sean Parnell. No immediate explanation was provided for Phelan’s sudden exit. The timing of Phelan’s departure coincides with ongoing military operations in the region. The U.S. Has seized two ships in the Strait of Hormuz, which Iran has characterized as a violation of a precarious ceasefire. The White House has maintained that the seizures involved international vessels and that the blockade remains effective. Phelan’s exit follows a series of recent leadership changes in the Defense Department, including the removal of Army Chief of Staff Randy George by Defense Secretary Pete Hegseth earlier in April 2026. Hegseth has cited concerns about officials associated with previous administrations as a factor in those decisions. As of this announcement, Phelan had served as Secretary of the Navy for approximately 13 months. His successor in an acting role, Hung Cao, previously held the position of Under Secretary of the Navy. The Pentagon statement expressed gratitude for Phelan’s service but did not elaborate on the reasons for his departure. Further details have not been made available through official channels.
