A U.S. Marine aboard the USS Anchorage goes missing during a training exercise off the Southern California coast, Pentagon officials say. The incident occurs late last week while the ship is conducting training, and Navy personnel launch a search operation. According to reports, the Marine was aboard the USS Anchorage when he disappeared during the exercise. As efforts continue, officials indicate that the nature of the search changes, shifting from active search to recovery. The reporting describes the effort as a coordinated Navy-led response following the Marine’s disappearance, with updates provided through Pentagon statements. Both outlets state that the USS Anchorage is the vessel involved and that the location is off Southern California. The shift to recovery reflects the status of the effort at the time of the latest updates, though specific details about circumstances of the disappearance are limited in the available summaries.
