Overview

• An internal CHP report confirms a 155 mm round fired from near White's Beach detonated midair over the closed Interstate 5 at about 1:46 p.m., scattering shrapnel.
• One fragment struck a CHP patrol car’s hood, leaving a minor dent and scratch, and officers reported debris falling like pebbles, with no injuries reported.
• After CHP notified Marines on site, additional live firings were canceled and the freeway’s northbound and southbound lanes were swept without finding further hazards.
• Camp Pendleton opened an investigation into a possible airborne detonation outside the designated impact area.
• Gov. Gavin Newsom, who had ordered a temporary 17-mile I-5 closure, criticized the exercise, while CHP urged a formal after-action review to improve intergovernmental coordination for events near public infrastructure.
