CBU 418

**CBU 418**, or Construction Battalion Unit 418, is a unit within the United States Navy Seabees. Established during World War II, CBU 418 was primarily tasked with construction, repair, and maintenance of critical infrastructure in support of naval operations in the Pacific Theater. The unit played a vital role in building airfields, roads, and support facilities in forward areas, often working under hazardous combat conditions. After the war, CBU 418 continued to support U.S. military operations and humanitarian missions, contributing to the Navy’s global engineering capabilities.
