The USS Dennis (DE-405) was a John C. Butler-class destroyer escort built for the United States Navy during World War II. Launched on December 4, 1943, by Brown Shipbuilding in Houston, Texas, and commissioned on March 20, 1944, she featured notable armament modifications, including a quadruple mount and twin mounts of Bofors 40 mm guns, providing a 50% increase in medium anti-aircraft firepower compared to most ships in her class. During her service, USS Dennis operated primarily in the Pacific Theater. She first arrived at Pearl Harbor on June 19, 1944, to escort convoys to Eniwetok and Kwajalein. She also screened the light carrier USS Belleau Wood and participated in exercises at Manus with Carrier Division 22. A significant engagement came during the Battle off Samar, part of the larger Battle of Leyte Gulf, where Dennis played a critical role. She was positioned as the last escort between the main force and the Japanese attack, and she was credited with torpedoing and sinking a Japanese heavy cruiser. During this battle, Dennis also rescued 434 survivors from the escort carrier USS St. Lo, which had been sunk by a kamikaze attack. Her actions contributed to her unit being awarded the Presidential Unit Citation. Following these operations, Dennis participated in the invasions of Iwo Jima and Okinawa, providing patrol, screening, and close air support duties. She rescued 88 crew members from the kamikaze-damaged escort carrier Sangamon and performed radar picket duty at Ulithi. After the war, she continued convoy escort duties before returning to the U.S. West Coast, arriving in San Diego in November 1945. She was decommissioned on May 31, 1946, and placed in reserve. USS Dennis earned four battle stars for her wartime service and was scrapped in 1973, leaving behind a distinguished record of her contributions during World War II.
