ww2dbaseUSS Hammann was commissioned into service in Aug 1939 under the command of Lieutenant Commander Arnold E. True. She conducted her shakedown cruise off the east coast of the United States, served in training roles in US waters, and then patrolled the North Atlantic between the US coast and Iceland. When the Pacific War brought the United States into WW2, she was at Iceland. She returned to Norfolk, Virginia, United States in Dec 1941, took on supplies, and set sail for the Pacific Ocean in early 1942. After training maneuvers in the New Caledonia area in the South Pacific, she participated in the Battle of the Coral Sea, during which she fired on incoming Japanese aircraft and then rescued 500 survivors of the disabled carrier USS Lexington. After light repairs at Pearl Harbor in the US Territory of Hawaii after the Battle of the Coral Sea, she participated in the Battle of Midway in the following month. She shot down several attacking aircraft attempting to approach USS Yorktown, but the carrier was nevertheless hit by two torpedoes. Hammann picked up Yorktown survivors, including Captain Elliott Buckmaster. In the morning of 6 Jun 1942, Hammann returned to the disabled Yorktown and transported a damage control party aboard, meanwhile providing water and power for firefighting efforts. In the afternoon, Japanese submarine I-168 fired a spread of four torpedoes at the pair of American ships. A 20-millimeter gun crew attempted to explode the torpedoes in the water, but to no success. Two of the torpedoes hit Yorktown, and one hit Hammann amidships. Hammann broke in half and sank very quickly; shortly after the sinking, there was an underwater explosion, possibly caused by detonated depth charges, which killed many survivors in the water and further damaged Yorktown. 80 men survived the sinking, including True, whose effective leadership during Coral Sea and Midway would later earn him the Navy Cross and the Navy Distinguished Service Medal awards.
