The USS Penobscot (ATA-188/ATR–115) was a Sotoyomo-class auxiliary fleet tug built for the United States Navy during World War II. Laid down by the Levingston Shipbuilding Company in Orange, Texas, on September 11, 1944, she was launched on October 12, 1944, and placed into service on December 12 of that year. Originally designated ATR–115, she was later renamed USS Penobscot (ATA–188) on July 16, 1948. Constructed as an auxiliary ocean tug, the vessel measured approximately 143 feet in length, with a beam of about 33 feet, and was powered by a diesel engine capable of providing a maximum speed of around 13 knots. Her design emphasized versatility and durability, allowing her to perform a wide range of tasks including towing, salvage, and recovery operations. During World War II, USS Penobscot served in the Pacific Theater, primarily based out of Pearl Harbor. She provided extensive advanced base towing services and visited numerous islands, supporting the Allied campaign as the victory in the Pacific approached. After the war ended, she briefly operated out of Chinese ports before returning to the U.S. in April 1946. She was then assigned to the 3rd Naval District, based in New York City, where she undertook towing operations along the East Coast, from Maine to the Caribbean, often spending half of each year away from her home port. In addition to towing, Penobscot participated in torpedo and naval mine recovery operations and supported fleet ships with various services. A notable example of her operational flexibility was her assistance in oceanographic research off Bermuda in May 1967, when she supported the USNS Mission Capistrano. In July 1967, she transferred to the Service Force, Atlantic Fleet, after undergoing overhaul at Staten Island. Decommissioned in 1971, USS Penobscot was placed in the Atlantic Reserve Fleet and was struck from the Navy List on February 28, 1975. She was later sold and, as of 2014, was in commercial service under the name American Lady, exemplifying her durable design and versatile service life.
