The USS Hammann (DD-412) was a Sims-class destroyer built for the United States Navy and launched on February 4, 1939, by the Federal Shipbuilding and Drydock Company in Kearny, New Jersey. Commissioned on August 11, 1939, under Commander Arnold E. True, the vessel featured typical design elements of the Sims class, optimized for fleet screening, anti-aircraft, and anti-submarine duties. Early in her service, Hammann conducted shakedown training off the East Coast and participated in readiness operations along both U.S. coasts. The destroyer quickly became an active participant in World War II operations following the attack on Pearl Harbor. After arriving in Hawaii in January 1942, Hammann joined Vice Admiral Fletcher’s Task Force 17 and took part in key campaigns in the South Pacific, including the Coral Sea and Midway. During the Battle of the Coral Sea in May 1942, Hammann served as a screening ship for the aircraft carrier Lexington, engaging Japanese aircraft and rescuing downed pilots amidst intense combat. When Lexington was torpedoed and sank, Hammann recovered nearly 500 survivors before herself being involved in a critical engagement. During the Battle of Midway in June 1942, Hammann screened the carrier Yorktown, aiding in the defense against Japanese aircraft. After Yorktown was torpedoed and abandoned, Hammann attempted to aid her, but was tragically struck by a torpedo from the Japanese submarine I-168. The explosion broke the destroyer in half, causing her to sink bow first within four minutes. Chief Machinist Mate Daniel William Carlson heroically helped others to safety during the sinking, which resulted in 80 fatalities. Throughout her service, Hammann was notable for her resilience and bravery in pivotal naval battles, earning two battle stars. Her service underscored her maritime significance as a resilient and active participant in critical naval engagements during the early years of the Pacific War.
