I Marine Expeditionary Force will host a live-fire Amphibious Capabilities Demonstration at Red Beach, Camp Pendleton, followed by a community Beach Bash at Del Mar Beach on Saturday, Oct. 18, 2025, to mark the Marine Corps’ 250th birthday and America’s Semiquincentennial.

The force training activities planned ensure our readiness to defend the Homeland and protect our Nation's interests abroad against emergent and unprecedented challenges today and in the years ahead.  The capabilities demonstration will feature integrated Navy and Marine Corps operations across air, land, and sea.

All training events will occur on approved training ranges and comport with established safety protocols.  No public highways or transportation routes will be closed.

In advance of the training event and demonstration, we conducted a detailed risk assessment. All participants will be briefed, medical, fire, and emergency assets will be on site, and multiple rehearsals will be conducted. All air, surface, and ground movements are scripted and rehearsed in accordance with standard operating procedures and established safety checklists.

Following the demonstration, Marines, Sailors and families will gather at Del Mar Beach for the Beach Bash, a celebration that recognizes the people who form the foundation of the Marine Corps’ strength - our families and the community – as we share in the celebration of 250 years of service. The event will include food vendors, music, static displays and family activities.

The White House Production Office will capture the Amphibious Capabilities Demonstration for inclusion in a national primetime broadcast on Nov. 9, ensuring Marine Corps contributions to America’s 250th birthday are highlighted for audiences across the nation.
