Note: This ship is a meticulously fictionalized vessel, derived from PT-810, PT-812, and the Higgins 78ft models, calculated through multiple sets of data.

Following the Pearl Harbor incident, the United States dispatched a large number of PT boats to the South Pacific and sent the 15th and 16th Motor Torpedo Boat Squadrons to the Mediterranean. Almost all boats of the 15th Squadron were annihilated in one battle. According to reports from the surviving PT-216 and PT-218, the Higgins 78ft model was utterly incapable of combating the German E-boats and several AFPs deployed in the Mediterranean. Consequently, the Naval Operations Command ordered the development of a new type of PT boat, requiring sufficient firepower to counter the Kriegsmarine's coastal forces.
In September 1943, four boat models entered the competition: the Elco 100ft, Higgins 96ft, Higgins 91ft, and Elco 98ft. The Higgins 96ft was eliminated due to its main gun becoming inoperable under certain sea conditions, and the Elco 100ft was excluded for its large size and high cost. Ultimately, the Higgins 91ft and Elco 98ft were chosen as the new generation of PT boats. The Elco 98ft had 121 units built, from PT-692 to PT-813, while the Higgins 91ft models started from PT-814.
The Higgins 91ft was designed with a 4mm STS hull to address the structural weakness of older PT boats, instead of the previous 40mm plywood, making it a steel torpedo boat rather than a plywood one. However, to save weight, the superstructure still used 15mm plywood.
PT-814, as the first vessel of the Higgins 91ft model, was commissioned in January 1945 and joined the 49th Squadron, heading to the Mediterranean for combat. To counter the German AFPs deployed in the Mediterranean, it was additionally equipped with two 18-tube MK50 rocket launchers.
