In a sudden shift at the Pentagon, Secretary of War Pete Hegseth has dismissed Navy Chief of Staff Jon Harrison, marking another round of high-level personnel changes. Details surrounding Harrison’s dismissal remain sparse, though sources indicate tensions over power dynamics within the Department of the Navy.
Harrison’s removal follows the Senate confirmation of Navy Undersecretary Hung Cao, with reports suggesting he sought to curtail the authority of the undersecretary role. A Pentagon statement acknowledged Harrison’s departure, stating, “He will no longer serve as Chief of Staff to the Secretary of the Navy,” while expressing gratitude for his service.
Harrison, a Trump-era appointee who joined in January, held an unusually prominent role, shaping significant reforms to the Navy’s policy and budgeting structures. He and Navy Secretary John Phelan reportedly restructured support for Cao, including reassessing aides and limiting direct access to military assistants.
This firing is part of a broader purge under Hegseth, who has targeted multiple senior Navy officials, including Admiral Lisa Franchetti, Vice Admiral Nancy Lacore, and Rear Admiral Milton Sands. The most notable departure was General Charles Q. Brown Jr., the first Black chairman of the Joint Chiefs of Staff, whose tenure ended in February 2025.
