President Donald Trump’s administration has removed its first service secretary, with Defense Secretary Pete Hegseth confirming the dismissal of Navy Secretary John Phelan over disagreements regarding the pace of naval shipbuilding reforms. The Pentagon announced Phelan’s departure on Wednesday, April 23, 2026, marking the first removal of a service secretary in the Trump administration. According to multiple reports, the decision stemmed from a deteriorating relationship between Phelan and senior defense officials, including Hegseth and Deputy Secretary of Defense Steve Feinberg, as well as concerns about the administration’s shipbuilding priorities.
Phelan, a wealthy Florida resident and former private investment fund manager, had no prior military experience before his appointment. He became a significant donor to Trump’s political campaigns and was appointed Navy Secretary despite lacking a background in defense or naval affairs. His removal follows increasing tensions within the Pentagon over defense strategy, particularly concerning the modernization of the U.S. Navy’s fleet. Officials familiar with the matter told The Guardian that Phelan was seen as moving too slowly on shipbuilding initiatives that Trump and Hegseth had prioritized, contributing to a breakdown in confidence in his leadership.
The timing of Phelan’s ousting coincided with heightened regional tensions, as Iran’s Islamic Revolutionary Guard Corps seized two container ships in the Strait of Hormuz the same week, citing maritime violations. However, defense officials emphasized that the firing was unrelated to the ongoing naval situation in the Gulf and was instead rooted in internal Pentagon dynamics. Reports indicate that Feinberg had sought to centralize authority over Navy shipbuilding and acquisitions, a move that reportedly gained traction amid the leadership change.
Before joining the administration, Phelan co-founded MSD Capital and served as its chief investment officer before departing in 2022 to establish Rugger Management LLC in Palm Beach, Florida. His financial background and political donations were frequently cited during his confirmation process, with critics questioning his qualifications to lead the Navy. Despite his lack of military service, Phelan had defended his ability to bring private-sector efficiency to defense procurement, though internal assessments reportedly concluded his approach did not align with the administration’s urgent timelines for fleet expansion.
Following Phelan’s removal, Deputy Navy Secretary Hung Cao, a former refugee and Navy officer, was named acting secretary of the Navy. Cao’s appointment represents a shift toward leadership with direct military experience, contrasting with Phelan’s corporate background. The change has been interpreted by some analysts as a signal that the administration intends to accelerate defense reforms with officials who have operational familiarity with the armed forces.
The dismissal adds to a pattern of high-level departures and reassignments within the Trump administration’s national security team, including the recent removal of Army Chief of Staff General Randy George. These developments have raised questions about the stability of military leadership amid ongoing global challenges, including maritime security in key chokepoints like the Strait of Hormuz and strategic competition with China.
As of now, no formal timeline has been announced for the nomination and confirmation of a permanent Navy Secretary. The administration is expected to submit a successor for Senate consideration in the coming weeks, though the process may be influenced by the ongoing focus on defense readiness and industrial base revitalization. Observers will monitor whether the next nominee brings either military service or deep expertise in naval acquisition to address the priorities that contributed to Phelan’s departure.
