yrbm 20

**YRBM-20** (Yard Repair, Berthing, and Messing 20) was a non-self-propelled barracks and repair ship operated by the United States Navy during the Vietnam War. Designed to provide maintenance, berthing, and messing facilities, YRBM-20 served as a floating base for riverine and coastal operations, supporting patrol boats and their crews in the challenging environments of the Mekong Delta. During its deployment, YRBM-20 was instrumental in repairing vessels, supplying logistics, and offering rest and recreation for sailors engaged in combat and patrol duties. The unit contributed significantly to the operational effectiveness of the U.S. Navy’s "Brown Water Navy," enabling sustained river operations throughout the conflict.
