U.S. Marines with Marine Operational Test and Evaluation Squadron (VMX) 1 take part in Gray Flag at Naval Base Ventura County, from Sept. 3, 2025, through Sept 19, 2025. Gray Flag is an annual large force test event that brings the Joint force together to test and evaluate multi-domain systems in a maritime environment, ensuring our nation’s warfighters are equipped with effective, interoperable systems that will help them deter aggression, protect our nation’s prosperity and security, and return home safely to their families.
