The USCGC Spencer (WPG-36) was a prominent Treasury-class cutter serving the United States Coast Guard from 1937 to 1974. Constructed as part of the Treasury-class, she was a robust and versatile vessel designed for a variety of missions, including search and rescue, maritime patrol, and wartime operations. Commissioned in 1937, the Spencer initially operated off Alaska’s fishing grounds, providing vital search and rescue services in the challenging Arctic environment. Measuring approximately 327 feet in length, the Spencer was equipped with a steam propulsion plant, reflecting her classification’s emphasis on durability and endurance. During World War II, when the Coast Guard temporarily joined the U.S. Navy, the Spencer saw extensive combat service. In the Atlantic, she served as a convoy escort and was credited with sinking German U-boats U-633 and U-175 in 1943, demonstrating her effectiveness in anti-submarine warfare. Later, in late 1944, she was assigned to the Pacific as a Communications Command Ship with the Seventh Fleet, participating in major amphibious assaults such as Luzon and Palawan during the Philippines Campaign. After the war, Spencer resumed her peacetime Coast Guard duties, primarily in the Atlantic, where she supported the burgeoning trans-Atlantic air industry by providing navigational assistance and search and rescue services for ships and aircraft. Her service extended into the Vietnam War, beginning in February 1969, where she conducted surveillance operations along the Vietnamese coast. Over ten months, she detected over 4,200 suspicious vessels, boarded 27 for cargo and crew inspections, detained 52 suspects, and supported land operations with 13 naval gunfire missions, targeting enemy bunkers and structures. Spencer’s distinguished 37-year career made her the most decorated cutter in Coast Guard history. Her final voyage occurred in January 1974 from New York City to the Coast Guard Yard, where she was decommissioned on January 23, 1974. Subsequently, she served as an engineering training ship until 1980 before being sold for scrap. Her long and varied service exemplifies her significant maritime and wartime contributions.
