Why Was the USS Michael Murphy's Commander Relieved?
The Navy has not said why. The only reason it gave was three words: "loss of confidence." Cmdr. Caitlin Cunningham was relieved as commanding officer of the destroyer USS Michael Murphy on September 27, 2026, less than a year after she took command on October 24, 2025. No more detail has been offered, and the Navy did not announce the removal when it happened.
The plain reality is this. A warship commander was taken off her ship in the middle of a war deployment, and the public only learned about it weeks later, when a Navy spokesperson confirmed it to USNI News on November 10. The ship was deployed to support operations against Iran. It stayed in the region after the aircraft carrier USS Abraham Lincoln left in August, and it came home to Pearl Harbor on November 12 after 346 days at sea, under a different commander. Nothing in that record shows a failed mission. The ship did the job it was sent to do. What is missing is the reason.
The Navy's claim is the standard one. "Loss of confidence" is the formula the service uses when it removes a commander, and it covers everything from a lost ship to a lost temper. The Hill reported that Rear Admiral Todd F. Cimicata, the commander of Carrier Strike Group 10, was the officer who relieved her. Cmdr. David Nicolas, who took command about a month before the ship came home, brought her back to Pearl Harbor. That is all the Navy has said.
"Loss of confidence" is the formula the service uses when it removes a commander — and it covers everything from a lost ship to a lost temper.
The principle is plain. A commander can be removed. That is the Navy's right, and it is part of how a military stays disciplined. But a removal carried out in silence is not the same as a removal carried out in the open. When the reason is kept back, no one outside the service can tell whether this was accountability for a real failure, or a failure covered up, or a commander removed for a reason that would not stand the light.
And the consequence follows from that silence. This was not the only one. The Navy also removed the entire command team of the nuclear submarine USS South Dakota — commanding officer, executive officer and chief of the boat — on October 14, after the submarine ran into something on the seabed, and it told Congress nothing about it. The Navy's attending physician for Congress and the Supreme Court, Rear Admiral Brian Monahan, also left his post during a Navy investigation, with no public announcement. Two senior House Democrats, Reps. Joe Courtney of Connecticut and Adam Smith of Washington, wrote to the Navy's leaders that the failure to inform Congress was unacceptable, and they demanded answers by November 20.
The details matter because they show a pattern, not a single case. The Michael Murphy deployed from Pearl Harbor on December 1, 2025, as part of the Abraham Lincoln Carrier Strike Group. The ship helped enforce the naval blockade in the Strait of Hormuz and operated in the north Arabian Sea and the Gulf of Oman. The carrier left the Middle East in August. The destroyer stayed behind. It left the region in mid-October, stopped in the Philippines in late October and Guam in early November, and came home after 346 days — about 24 days longer than the carrier's deployment. The Navy has warned families that deployments of 10 to 11 months will be the new standard for the next couple of years.
Normally, the firing of a ship's commanding officer is announced within days. Here there was no announcement at all, and no public comment even when the Navy was asked. That is what made the lawmakers angry. As Courtney and Smith put it in their letter, "what should have been a standard exercise in information sharing has instead raised questions about the Navy's commitment to transparency and its commitment to a productive working relationship with Congress."
If a removal is routine, why hide it? That is the question the Navy still has to answer.
