YRBM 21

• YRBM 21 Designation: YRBM-21 stands for "Yard Repair Berthing and Messing Barge," a type of non-self-propelled barge used by the U.S. Navy during the Vietnam War. • Role in Vietnam: YRBM-21 served as a floating base, providing repair, berthing, and messing facilities to riverine forces engaged in the Mekong Delta, supporting patrol boats (PBRs), minesweepers, and other small craft. • Construction: YRBM-21 was originally built as a barracks ship and later converted for its specialized riverine support role, featuring workshops, living quarters, and supply storage. • Mobile Support Base: The barge was towed to various locations along the Mekong and its tributaries, allowing it to provide direct support to U.S. Navy and allied forces in contested areas. • Target for Enemy Action: YRBM-21 and similar barges were frequent targets for Viet Cong sappers and rocket attacks due to their vital role and relatively stationary presence in dangerous waters. • Crew Life: Life aboard YRBM-21 was challenging, with sailors facing constant threat of attack, high temperatures, and difficult living conditions, but also camaraderie and a sense of mission supporting frontline riverines. • Fire Support: The barge was typically equipped with defensive armament, such as .50-caliber machine guns and occasionally more substantial weapons, to fend off enemy boats and shore attacks. • Decorations and Commendations: Units operating on and from YRBM-21 earned numerous commendations, including the Navy Unit Commendation and awards for meritorious service under hazardous conditions. • Legacy: Veterans of YRBM-21 formed strong bonds, and some have maintained reunions and online communities documenting their experiences and preserving the vessel’s history. • Post-war Fate: After the Vietnam War, YRBM-21 and similar barges were decommissioned or transferred to other uses, with some scrapped, while others continued serving in support roles or were mothballed.
