UPDATE: A live artillery shell detonated over California’s Interstate 5 during a Marine Corps demonstration, striking a California Highway Patrol (CHP) vehicle with debris, authorities confirmed just moments ago. Fortunately, there were no injuries reported, but the patrol car sustained significant damage.
The incident occurred on October 20, 2025, near Camp Pendleton, where the U.S. Marine Corps was conducting a live-fire event as part of its 250th Amphibious Capabilities Demonstration. This demonstration aimed to showcase the Navy-Marine Corps’ ability to project combat power globally. The shell reportedly detonated prematurely in mid-air while CHP officers were managing traffic during the event.
CHP Border Division Chief Tony Coronado, an active Marine, called the situation “unusual and concerning,” emphasizing that it is “highly uncommon” for any live-fire training to occur over an active freeway. As a precaution, the Marine Corps has **canceled additional live-fire demonstrations** pending an investigation into the incident.
“We are aware of the report of a possible airborne detonation of a 155mm artillery round outside the designated impact area,” said CHP spokesperson Capt. Gregory Dreibelbis. He added that the demonstration had undergone a rigorous safety evaluation. “Following established safety protocols, firing was suspended,” he stated.
California Governor Gavin Newsom had previously closed a section of I-5 ahead of the event, citing safety concerns. In a statement, he criticized the decision to conduct live fire over a busy highway, arguing that it prioritizes “ego over responsibility.” Newsom stated, “This could have killed someone,” expressing relief that the freeway had been closed before the incident occurred.
This alarming event raises serious questions about safety protocols and coordination between federal, state, and local authorities. The CHP has initiated an internal review, recommending a thorough after-action review to enhance future planning and communication during such events.
The impact of this incident extends beyond the immediate damage to the CHP vehicle. It has sparked significant public outrage and raised concerns about military activities conducted in close proximity to civilian areas. As investigations unfold, the public is urged to stay informed about developments regarding the Marine Corps’ operational safety measures.
