History

USS Allen M. Sumner (DD-692) was an American destroyer and the lead ship of her class, laid down for the US Navy in 1943. A direct improvement over the preceding Fletcher class destroyers, the Sumner were more heavily armed with six 5 inches/127mm dual purpose main guns in three twin turrets, more manoeuvrable thanks to two rudders instead of one and had more light anti-air guns, all of this on a hull of the same length as the Fletcher but just slightly wider and heavier, about 750 tons more. The torpedoes armament remained the same with two quintuple 21 inches/533mm torpedoes launchers. The ASW capability of the Sumner was an improvement over the Fletcher’s one, since the double rudder allowed the ships to be more manoeuvrable to perform ASW works. 70 Sumner were planned, but only 58 were completed, the 12 others being converted in Robert H. Smith class minelayer during their construction. Only USS Laffey (DD-724) survived as a museum ship, under her FRAM II configuration.

She received 2 battle stars during world war two for her service in the Pacific.

Commissioned in early 1944, Sumner did her shakedown trial in Bermudas before being assigned to Norfolk as a training platform until august, when she was sent to the Pacific. Arriving at Pearl Harbor in September, she conducted anti-air and anti-submarine training during her journey and resumed training once at Pearl. She stayed in Hawaii until October when she joined, with USS North Carolina (BB-55), the Fast Carrier Task Force in the western Pacific. In the Task Force, she conducted multiple escorts and patrol duties as well as AA cover for the carrier group. In early December, she was deployed at Ormoc Bay, alongside her sisterships USS Moale (DD-693) and USS Cooper (DD-695) to intercept a Japanese convoy. There, Sumner suffered from a near miss bomb dropped from a reconnaissance plane which started a fire on board, and later the three destroyers made contact with two Japanese escort destroyers, Kuma and Take. Sumner and Cooper sank Kuwa ten minutes only after the start of the engagement, and joined Moale against Take. Witnessing Cooper’s sinking after taking a torpedo from the Japanese destroyer, the Sumner crew wasn’t able to rescue the lost destroyer because of the constant air attacks and shore bombardments. The two destroyers retreated laters, and joined San Pedro Bay for repair. Immobilised during nine days, she returned to the Fast Carrier Task Force once the repairs were completed and contributed to multiple AA cover and shore bombardment during the landing on Mindoro Island. After the invasion, Sumner returned to Leyte where she stayed until the end of the year, conducting escort on resupply echelon to Mindoro.

In January of 1945, Sumner joined Task Group 77.2 to provide fire support to the invasion of Luzon. She also took part in a minesweeping operation, where her unit was attacked by kamikaze planes. A plane crashed in the middle of Sumner’s hull port side, behind the aft torpedo mount, killing 14 men in the attack. The damages caused by the kamikazes led the ship to retire from the minesweeping operations, but she remained in action alongside the Task Group until mid-January, when she started a journey back to the USA. After multiple stopovers on the way, most notably at Pearl Harbor, she finally joined Hunters Point in California in early February for repairs. The work was finished in April, and Sumner was assigned as a training platform, much like after her commission a year earlier. Three months later, she was relieved of training duties and joined Pearl Harbor for three weeks of training operations. In August, Sumner again joined the war zone, but Japan surrendered only two days after she left Hawaii. She continued her voyage and joined Task Group 38 in the Japanese waters, where she fulfilled post-war patrols. Remaining among the fleet to conduct patrols until September, she returned to the US in October and resumed once again the role of a training platform. She was briefly reassigned to the Operation Crossroad at Bikini Atoll, in the Marshall Islands, before returning to training duties.

After the war, she was assigned to the Atlantic Fleet, conducting peace time operations near Norfolk and a tour of duty in the Mediterranean in 1950. During the Korean War, Sumner conducted AW screening for the fast carrier group until the armistice. In the following eight years, she conducted multiple deployments in European waters, as well as taking part in NATO exercises. During the Suez crisis, Sumner supported the evacuation of American citizens. In 1961, she was modernised to improve her ASW capabilities, and in 1962, she took part in the Cuba blockade. In 1967, she was deployed to Vietnam, screening the nuclear guided missile cruiser USS Long Beach (CGN-9) before being assigned to Operation Seadragon to stop communists waterborne operations, as well as operation Bear Charger, an amphibious assault. Later in the year, she returned to the United States. In 1969, she took part in the NATO review to celebrate the 20th anniversary of the alliance, and in 1971, she was assigned to the Naval Reserve as a training ship. She was decommissioned in 1973 and sold for scrap in 1974.

In World of Warships Legends, USS Allen M. Sumner is represented in her as-built configuration. However, she lacks one 20mm Oerlikon gun compared to the class designed AA suit : the Sumner class DD had 11 20mm Oerlikon (11x1) and 12 40mm Bofor (2x4 and 2x2), and Sumner in-game only have 10 of the 20mm Oerlikon.
