March 21, 1919 Alexander Maksymovych Dyachenko (Alex Dyachenko) – a sailor who perished as a hero during the Second World War – was born in the family of Ukrainian emigres in the city of Hartworth, Connecticut, USA, in honor of his name, the US Navy landing force ‘Diachenko’.
September 24, 1940 Alex volunteered to join the US Navy. After training he was appointed as a bilge driver for the destroyer ‘Eberli’ (‘Eberle’ DD-430). Even before the US-US war with Germany, the US Navy helped to protect the British convoy. In September 1941, Eberli, within the operational group, guarded the convoy of the NH-150 from the shores of Canada to the middle of the Atlantic Ocean, where the convoy was transferred under the protection of the Royal Navy of Great Britain. Captivated by an interesting service, Diachenko planned to enter the Naval Academy in Annapolis. 11/08/1942 The American fleet strike group, which included Eberli, provided fire to the artillery fire within the Operation Smoloskyp with the landing of a Western group of troops in the area of the Mehdi port in French Morocco. After a short rest and repair in Norfolk, December 26, 1942, Erbeli went out to patrol the southern Atlantic for the purpose of intercepting enemy ships that traveled between German and Japanese ports. March 10, 1943 the US Navy Task Force discovered a German ship ‘Karin’. The crew was given a command to capture ‘Karin’, on board which could have a valuable cargo. After the first warning shots, Karin stopped, and his crew set fire to his ship and landed on a boat. 14 volunteers – 2 officers and 12 sailors, and among them Dyachenko, formed a survey group and immediately went on a boat to a burning ship. American sailors were supposed to extinguish the fire, to find and dispose of explosive charges, and most importantly – to find secret documents and equipment. Alex fought for survivability in the engine room, but there was not enough time to extinguish the fire and several powerful explosions took away the lives of seven heroes. Other members of the observation team were forced to leave the Karin, which was already impossible to escape from flooding. All seven heroes were posthumously awarded the Silver Star. In their honor, they received the names of the new ships of the US Navy.
High-speed military transport APD-123 was launched on July 18, 1944 as ‘Alexander Diachenko’, launched into water on 15.08.1944 as ‘Alex Diachenko’, became part of the US Navy on 08/12/1944 as ‘Diachenko’. During the Second World War, Diachenko provided landings to the Philippines, Borneo, Korea, and Taiwan. During the war, China carried traffic between the ports of this country. On it were evacuated to Taiwan military and civilians who left China. During the Korean War, ‘Diachenko’ is used in combat with a team of combat swimmers. In May 1955 APD-123 evacuated peaceful refugees from Haitian-reached war (Indochina). Subsequently, until 1974, the APD-123 provided training for combat swimmers.
