The USS Johnston (DD-557) was a Fletcher-class destroyer constructed for the United States Navy during World War II. Laid down in May 1942 at the Seattle-Tacoma Shipbuilding Corporation's yard and launched on 25 March 1943, she was commissioned on 27 October 1943 under Lieutenant Commander Ernest E. Evans. The Fletcher class was designed to address stability issues found in earlier classes, resulting in an increased size and displacement—about 2,100 long tons standard and 2,544 long tons at deep load. The ship measured approximately 376 feet 6 inches in length, with a beam of 39 feet 8 inches and a draft of 17 feet 9 inches. Powered by two General Electric geared steam turbines producing 60,000 shaft horsepower, Johnston could reach speeds up to 37.8 knots, with a range of 4,490 nautical miles at 15 knots. Her armament included five dual-purpose 5-inch/38 caliber guns, supplemented by ten 40mm Bofors guns, seven 20mm Oerlikon cannons, torpedo tubes for Mark 15 torpedoes, and depth charge racks and K-gun throwers for anti-submarine warfare. The ship's armor was minimal, designed mainly for protection against splinters and fragments, with some steel plating on vital compartments and reduced splinter protection on the bridge and fire-control director. Johnston's service history was marked by active participation in key Pacific campaigns, including the Gilbert and Marshall Islands, Mariana, Palau, and the Philippines. Her most notable action was during the Battle off Samar on 25 October 1944, where she fought valiantly against a superior Japanese fleet led by Vice Admiral Takeo Kurita, including the battleship Yamato. During the battle, Johnston engaged heavily armed Japanese ships, firing over 200 shells and torpedoes at cruisers like Kumano, and was ultimately hit by multiple shells from Yamato, which caused severe damage. Commander Evans and 186 crew members lost their lives, with Evans posthumously awarded the Medal of Honor. The wreck of USS Johnston was discovered in 2019 at a depth of over 21,000 feet, making it the deepest shipwreck ever surveyed until 2022. The ship's remains lie upright, with significant damage from enemy fire still visible, including holes from shells and the split hull caused by a direct hit from Yamato. Johnston's legacy is marked by heroic sacrifice, recognized through six battle stars and a Presidential Unit Citation.
