Military bases in San Diego County, Twentynine Palms, and across the country have increased security measures in response to last weekend's U.S.-Israeli attacks on Iran. This has led to traffic delays at base entrances, enhanced ID checks, and access restrictions for visitors.

Why it matters

The attacks on Iran were part of a larger military operation, and the increased security at these bases is a precautionary measure to protect personnel and assets in the aftermath. The situation highlights the ongoing tensions between the U.S., its allies, and Iran, and the potential for further escalation.

The details

The Naval Air Station North Island on Coronado, which ports three aircraft carriers including the USS Abraham Lincoln that led some of the initial attacks, has warned of possible delays at all base entry points. The Marine base in Twentynine Palms has also increased security, suspending its Trusted Traveler Program until further notice. The heightened security posture is expected to cause delays at the gates and visitors' center.

  • The U.S. and Israeli operations began striking targets at 1:15 a.m. Eastern Time on Saturday, March 2, 2026.
  • As of Tuesday, March 4, 2026, at least six U.S. service members had been killed in action.
