The USS Tamaroa (AT-62) was a United States Navy tugboat constructed for the Coast Guard in 1919 by the Bethlehem Shipbuilding Corporation in Elizabeth, New Jersey. She was transferred to the Navy on May 14, 1936, at San Francisco, California, and commissioned at Mare Island Navy Yard on November 6, 1936. As an ocean tug, she measured a length typical of the fleet and was designated as AT-62. Throughout her nearly decade-long service, Tamaroa operated primarily in the San Francisco area, serving the 12th Naval District under the command of the district's commandant. Initially classified as a fleet ocean tug, Tamaroa was reclassified as a harbor tug (YT-136) on January 1, 1938, reflecting her focus on harbor duties. She was later reclassified again on April 13, 1944, as a large harbor tug (YTB-136), indicating an upgrade in her capacity. Despite these reclassifications, her primary role remained in harbor and local operations within the San Francisco Bay area, supporting naval activities during a period that spanned pre-World War II and wartime service. Tamaroa’s service was marked by her consistent presence in the San Francisco harbor, contributing to fleet logistics and harbor operations. Her career was abruptly ended on January 27, 1946, when she was involved in a collision with the USS Jupiter (AVS-8). The collision resulted in Tamaroa sinking in 42 feet of water in San Francisco harbor. Her name was struck from the Navy list shortly thereafter, on February 25, 1946. The USS Tamaroa's service exemplifies the vital, though often behind-the-scenes, role played by auxiliary vessels such as tugs in maintaining fleet readiness and harbor operations during a significant period of naval history.
