The USS Chehalis (AOG-48) was a Patapsco-class gasoline tanker constructed for the United States Navy during World War II. Laid down on November 6, 1943, in Savage, Minnesota, by Cargill, Inc., she was launched on April 15, 1944, and officially commissioned on December 5, 1944. Designed to transport gasoline to warships and remote Navy stations, the Chehalis was a vital logistical asset during her service. Following her shakedown, the Chehalis departed Galveston, Texas, on January 5, 1945, heading to San Diego and then onward to Pearl Harbor, arriving on February 6, 1945. She conducted fueling operations across the Hawaiian Islands and in Canton in the Phoenix group, supporting training activities. In May, she traveled to the Philippines, arriving at San Pedro Bay with aviation gasoline and lubricants, and subsequently provided fueling support to motor torpedo boats and U.S. Army crash boats along the Leyte coast and at Okinawa. During her time at Okinawa, she endured multiple typhoons, which temporarily halted operations but demonstrated her crew’s resilience and familiarity with battle stations. After completing her duties in the western Pacific, Chehalis returned to Olympia, Washington, in December 1945, where she received a warm welcome from the city of Chehalis, whose residents had helped fund her through war bonds. Following an overhaul at Puget Sound, she resumed service in the Pacific, supplying fuel across various islands including Johnston, Palmyra, Samoa, Kwajalein, and Iwo Jima through mid-1946. Tragically, on October 7, 1949, while docked at Tutuila in American Samoa, an explosion in one of her gasoline tanks resulted in the deaths of six crew members. The ship caught fire, capsized, and sank in 45 feet of water. She later slid into deeper waters, and her wreck was later salvaged and sold to the government of American Samoa in 1955. The vessel’s cargo included ammunition and petroleum, and environmental measures led to the removal of remaining fuel by 2010, although the ammunition was not removed. The USS Chehalis played a significant role in post-war Pacific logistics, exemplifying the dangerous but crucial support operations conducted by auxiliary ships during and after World War II.
