In a stunning reorganization at the Pentagon, Defense Secretary Pete Hegseth abruptly removed Navy Chief of Staff Jon Harrison following the Senate’s confirmation of Hung Cao as Navy Under Secretary.

That decision, though controversial to some, underscores a larger mission of restoring accountability and alignment to our nation’s military leadership.

“He will no longer serve as the Chief of Staff of the Secretary of the Navy. We are grateful for his service to the Department,” a Pentagon spokesman said. Harrison has not spoken publicly about his removal.

Harrison was a political appointee tied to the prior administration. In his role, he joined Navy Secretary John Phelan to overhaul the Navy’s budget and policy offices—missions that had long languished under bureaucratic paralysis.

Yet insiders say Harrison attempted to rein in the power of the new undersecretary.

One official, speaking anonymously, alleged that Harrison “had attempted to limit the role of the undersecretary, Navy veteran Cao, and had reassigned aides meant to help Cao in his new role.”

That kind of internal power play simply cannot stand. Cao, a Navy veteran and steadfast Republican, ran for office in Virginia and has now been tapped to lead from within the halls of naval power.

For true reform, the undersecretary must carry autonomy and influence commensurate with the role.

This action is not an isolated instance. Hegseth has dismissed several top aides this year—including senior advisor Dan Caldwell, deputy chief of staff Darin Selnick, and Colin Carroll, the chief of staff to the deputy Secretary of War.

He has also relieved the Chairman of the Joint Chiefs of Staff, Gen. C.Q. Brown; Chief of Naval Operations Adm. Lisa Franchetti; Commandant of the Coast Guard Adm. Linda Fagan; and several other uniformed leaders.

Some critics see purge. But viewed through a sober lens, these moves reflect a bold effort to shake loose lethargic bureaucracies and install leaders who reflect a renewed national priority: strength, clarity, and loyalty to the mission.

After all, the nation is in a shipbuilding crisis. While rivals race ahead with next-generation naval platforms, U.S. shipyards struggle to meet timelines on even basic maintenance.

In his address to Congress this year, President Trump pledged to “revive America’s struggling shipbuilding industry,” promising a new White House shipbuilding office.

That office has since moved to OMB, following the ouster of Mike Waltz from the NSC in the wake of the Signalgate scandal.

Speaking of Signalgate: Waltz created a group chat on Signal in March to discuss a proposed U.S. strike against Houthi rebels in Yemen. The Atlantic’s editor-in-chief, Jeffrey Goldberg, was accidentally added.

Hegseth then shared sensitive details drawn from a classified email. The Pentagon Inspector General is still investigating the breach.

Yes, the Signal affair demands scrutiny. But that same scrutiny must apply to entrenched lines of authority that have allowed dysfunction to breed. The reform movement cannot succeed if loyalty is only demanded of some and abdicated by others.

At the same time, skeptics will argue that these frequent firings lead to instability. But strong institutions are designed for renewal, not reverence for those whose record includes stasis.

It’s nearly impossible to change a culture with the same people who helped create or benefit from that culture—even those appointed by earlier administrations.

Hegseth’s message is clear: the Pentagon must be remade. Leadership must mirror purpose. The undersecretary must not be handicapped by internal sabotage.

The Navy must finally be capable of catching up and surpassing adversaries. The chain of command must function without political obstruction.

As the smoke clears, what is undeniable is that we are witnessing a decisive reset. The Navy—and the broader defense establishment—needs unflinching direction for a more dangerous world. This is not chaos. This is corrective action.
