U.S. Secretary of Defense Pete Hegseth Fires Navy Chief of Staff

• Defense Secretary Pete Hegseth removes Navy Chief of Staff Adm. Jon Harrison from his position.
• The decision follows the Senate confirmation of retired Navy officer Hung Cao as the new Under Secretary of the Navy.
• The move signals a broader shake-up in Pentagon leadership amid growing internal divisions.

U.S. Defense Secretary Pete Hegseth has dismissed Admiral Jon Harrison, the Chief of Staff of the U.S. Navy, just hours after the Senate confirmed Hung Cao as the new Under Secretary of the Navy. The decision marks the most significant leadership change in the Navy since the Trump administration’s return to office.

Sudden Dismissal and Transition Of Power

According to Pentagon officials, Hegseth informed Admiral Harrison of his removal late Friday evening, citing a need for “new direction and accountability” within the service. The announcement came shortly after Hung Cao, a retired Navy captain and former special operations officer, was officially confirmed by the Senate.

“The Navy requires bold leadership and a return to readiness,” Hegseth said in a statement. “We appreciate Admiral Harrison’s years of service, but it is time to move forward under new leadership.”

Sources close to the matter described the move as abrupt but anticipated, noting recent tensions between Harrison’s office and civilian leadership over fleet readiness priorities and shipbuilding delays.

Cao’s Confirmation and Priorities

Hung Cao, a former congressional candidate and naval officer with combat experience in Iraq and Afghanistan, is expected to emphasize fleet modernization, personnel reform, and expanding shipyard capacity as immediate goals. His appointment has been welcomed by several lawmakers aligned with President Trump’s defense policy agenda, which calls for aggressive naval expansion to counter China and renewed investment in domestic shipbuilding.

Cao has publicly argued that the U.S. Navy must “regain maritime dominance” through a combination of larger fleet size, improved training, and tighter budget discipline.

Internal Rifts Within The Navy

Admiral Harrison’s departure underscores growing rifts within the Navy’s upper ranks. In recent months, internal reports pointed to disputes over funding allocations between the surface warfare and submarine communities, as well as the service’s handling of recruitment and retention shortfalls.

Under Harrison, the Navy had pushed for a more cautious procurement strategy, prioritizing long-term shipbuilding stability over rapid expansion. The approach clashed with Hegseth’s and Trump’s insistence on accelerating production of new submarines and destroyers, especially under the AUKUS and Pacific deterrence initiatives.

The removal of Admiral Harrison is part of a broader reorganization effort by Defense Secretary Hegseth, who has reportedly sought to replace several senior officers viewed as resistant to the administration’s directives. Similar leadership changes are being considered across other branches, particularly in the Air Force and Space Command.

“The President expects alignment with his vision for a stronger, more assertive military,” one senior defense official said. “Those unwilling to execute that vision will be replaced.”
