About this Unit
YRBM 21, or "Yard Repair, Berthing, and Messing Barge 21," served as a vital support vessel for the U.S. Navy during the Vietnam War. Commissioned in the late 1960s, YRBM 21 operated primarily in the Mekong Delta, providing essential repair facilities, berthing, and mess services to riverine and patrol craft engaged in Operation Game Warden and other brown-water naval operations. The barge was frequently stationed at forward operating bases along key waterways, enabling rapid maintenance and logistical support close to combat zones. YRBM 21's contributions were crucial to maintaining the operational readiness and effectiveness of the riverine forces throughout its deployment in Southeast Asia.
