The USS McCulloch was a significant vessel in United States maritime history, serving in multiple capacities from its launch in 1896 until its sinking in 1917. Built by William Cramp & Sons in Philadelphia at a cost of $196,500, she was the largest cutter ever constructed for the Revenue Cutter Service, featuring a composite hull of wood planks mounted on a steel frame. She measured approximately 258 feet in length and was equipped with a single triple-expansion steam engine, complemented by a barkentine rig that allowed extended range under sail power. Her armament included four 3-inch (76 mm) guns mounted in sponsons on her forward and aft quarters, and a 15-inch (381 mm) torpedo tube integrated into her bow stem. The ship's construction combined traditional sailing rigging with steam propulsion, making her versatile for various missions. She was commissioned into the Revenue Cutter Service on December 12, 1897, and was named after Hugh McCulloch, a notable American statesman and Treasury Secretary. McCulloch's early service was marked by notable combat during the Spanish–American War. She was part of Commodore Dewey’s Asiatic Squadron and participated in the Battle of Manila Bay in 1898. During this engagement, she played a vital role in guarding the store ships, engaging Spanish batteries, and maintaining line integrity under fire. She also transported Emilio Aguinaldo from Hong Kong to Manila after the battle. Her performance was highly praised, and she was awarded several Hotchkiss guns taken from the Spanish flagship. Post-war, McCulloch operated along the U.S. West Coast from San Francisco, conducting law enforcement, lifesaving, and patrol duties, including rescue operations off Alaska and enforcement of fur seal regulations in the Pribilof Islands. In 1914, she underwent significant overhaul at Mare Island Navy Yard, removing her barkentine rig and upgrading her boiler systems. In 1915, following the merger that created the U.S. Coast Guard, she became USCGC McCulloch, continuing her patrols. She was transferred to the U.S. Navy in 1917 for World War I service as USS McCulloch. Her career ended on June 13, 1917, when she was struck and sunk after a collision with the passenger steamer Governor off Point Conception, California. The wreck was discovered in 2016, and her remains were formally recognized and listed on the National Register of Historic Places in 2021, cementing her legacy as a vessel of remarkable service and maritime significance.
