The USS Marcus (DD-321) was a Clemson-class destroyer constructed for the United States Navy in the post-World War I era. Laid down on May 20, 1919, by the Bethlehem Shipbuilding Corporation in San Francisco, she was launched on August 22, 1919, and commissioned on February 23, 1921. The Clemson class was a near-replica of the Wickes class, with added fuel capacity, displacing approximately 1,290 long tons at standard load and extending over 314 feet in length with a beam of nearly 31 feet and a draft of just over 10 feet. The ship's crew comprised six officers and 108 enlisted men. Powered by two steam turbines driving twin propellers, the USS Marcus's machinery was designed to generate 27,000 shaft horsepower, enabling her to reach speeds of up to 35 knots. She carried a maximum of 371 long tons of fuel oil, giving her an operational range of approximately 2,500 nautical miles at 20 knots. Her armament included four single-mounted 4-inch guns, supplemented by anti-aircraft weapons which varied over time due to shortages, and a formidable torpedo battery of twelve 21-inch tubes arranged in four triple mounts. The ship also featured depth charge rails and, in many cases, a Y-gun depth charge thrower for anti-submarine warfare. After her commissioning, USS Marcus served with the Pacific Fleet, operating off the West Coast, from Seattle to Panama. Her activities included fleet maneuvers, tactical exercises in Hawaiian waters, Caribbean fleet operations, and naval reserve training cruises. Notably, she participated in simulated attacks on the Panama Canal and fleet maneuvers in the Caribbean and Hawaiian regions during the 1920s. Decommissioned on May 31, 1930, in San Diego, Marcus was disposed of following the London Naval Treaty, being struck from the Navy list in 1935 and subsequently sunk by gunfire on June 25, 1935. Her service exemplifies the interwar naval strategy and the technological characteristics of early 20th-century destroyers, contributing to the US Navy’s fleet readiness during that period.
