The USS Choctaw (AT-70), later redesignated ATF-70, was a Navajo-class fleet tug built for the United States Navy during World War II. Constructed by Charleston Shipbuilding and Drydock Co. in Charleston, South Carolina, she was laid down on April 4, 1942, launched on October 18, 1942, and commissioned on April 21, 1943. The vessel was designed primarily for towing duties, assisting ships by towing on the high seas, especially in combat or post-combat zones, along with other auxiliary tasks. Her service during World War II was concentrated in the Atlantic theater, notably at Bermuda from June 17, 1943, to May 8, 1944. During her time there, she supported convoy assembly and training exercises, providing tug and target-towing services. On May 15, 1944, she was reclassified as ATF-70. After her reclassification, she continued her operations, including towing USS Holder (DE-401) from Oran to New York City in May-June 1944, and later towing two LSTs from Wales to New York in late September 1944. Following an overhaul at Norfolk, Virginia, Choctaw continued her duties along the Atlantic coast and in Newfoundland, providing salvage services and towing targets, notably assisting the collision-damaged USS Huron back to Bermuda and Charleston. Her operational scope extended into the Caribbean and east coast waters until October 1946. She was decommissioned at Orange, Texas, on March 11, 1947, and placed in reserve, remaining inactive for approximately three decades. In 1978, after being struck from the Naval Register, USS Choctaw was transferred to the Colombian Navy under the Security Assistance Program and was renamed ARC Pedro De Heredia (RM-72). Her service exemplifies the logistical and support roles crucial to naval operations during WWII, particularly in convoy assembly, salvage, and towing duties, contributing significantly to Allied maritime operations during the war.
