The Elco 80ft PT-565 was the lead boat of the 57 boats built for the namesake subclass of Elco PT boats. It was laid down at the Elco shipyard in Bayonne on 28 April 1944, launched on 20 September, and commissioned on 8 December that year. It was assigned to the 38th Motor Torpedo Boat Flotilla in the southern Pacific, but saw little service throughout the remainder of the Pacific war, with the only notable action being the bombardment around Borneo in August 1945. After just 10 months of service, the PT-565 was decommissioned on 24 October 1945 and disposed of.

The PT-565 was introduced in Update 1.77 "Advancing Storm". As a late member of the Elco 80ft PT boat family, it sports similar armament to the Higgins counterpart, the PT-200. Equipped with the 37 mm gun derived from the P-39 Airacobra at the bow and the powerful 40 mm Bofors autocannon at the stern, this arrangement encourages hit-and-run or ambush tactics, as the Bofors offers much more reliable firepower. It also has an option to equip rockets at the bow that can deal good damage against larger ships. However, much like any other PT boat, the PT-565 is still vulnerable from the sides and cannot afford taking hits.
