CBMU549

Construction Battalion Maintenance Unit 549 (CBMU-549) was a United States Navy Seabee unit activated during the Vietnam War. Established in 1966, its primary mission was to provide construction, repair, and maintenance support to U.S. Navy and Marine Corps operations throughout the Republic of Vietnam. CBMU-549 was instrumental in constructing and maintaining bases, airfields, and essential infrastructure, often working under hazardous conditions and enemy fire. The unit was decommissioned in 1971, having played a vital role in enabling sustained U.S. military operations in Southeast Asia.
