USCGC Greenbrier (WLR-75501)

The USCGC Greenbrier (WLR-75501) is a United States Coast Guard inland construction tender. Greenbrier and her sister ships, the Pamlico and Salm (WLR-75402 & 75502 respectively), are specifically designed to construct, repair, and maintain floating aids to navigation (ATON) throughout the United States inland waterway system. These aids include buoys and dayboards, essential for safe navigation on rivers, canals, and other navigable inland waters.

Unlike larger seagoing buoy tenders, the Greenbrier class is characterized by its shallow draft and maneuverability, allowing it to operate effectively in constricted waterways. The ship's primary function is to deploy and recover buoys, repair damaged aids, and replace those that are missing or malfunctioning. To perform these tasks, the Greenbrier is equipped with a crane, deck space for buoy storage, and a crew trained in buoy maintenance and navigation. The WLR designation signifies "Western Rivers Buoy Tender," further highlighting the ship's intended operational environment. The homeport of the Greenbrier is Leavenworth, Kansas.
