Marine Barracks NWS Seal Beach

Marine Barracks Naval Weapons Station (NWS) Seal Beach was established in 1944 to provide security for the vital ammunition depot supporting the Pacific Fleet during World War II. The Marine unit’s primary mission has been to safeguard ordnance operations, facilities, and personnel, ensuring secure handling and storage of munitions through subsequent conflicts including the Korean War, Vietnam War, and the Global War on Terrorism. Over the decades, Marines stationed at NWS Seal Beach have also participated in ceremonial functions and community engagement, reinforcing military-civilian relations. Today, the Marine Barracks continues its tradition of vigilance, adapting to evolving security challenges in support of national defense objectives.
