PT 109 was one of the hundreds of motor torpedo Boat and Ship Models/Boats-Sail (PT) of the PT 103 class completed between 1942 and 1945 by Elco Naval Division of Electric Boat Company at Bayonne, New Jersey. The Elco Boat and Ship Models/Boats-Sail were the largest in size of the three types of PT Boat and Ship Models/Boats-Sail built for U.S. use during World War II. Wooden-hulled, 80 feet long with a 20-foot, 8-inch beam, the Elco PT Boat and Ship Models/Boats-Sail had three 12-cylinder Packard gasoline engines generating a total of 4,500 horsepower for a designed speed of 41 knots. With accommodations for 3 officers and 14 men, the crew varied from 12 to 14. Its full-load displacement was 56 tons. Early Elco Boat and Ship Models/Boats-Sail had two 20mm guns, four .50-caliber machine guns, and two or four 21-inch torpedo tubes. Some of them carried depth charges or mine racks. Later Boat and Ship Models/Boats-Sail mounted one 40mm gun and four torpedo launching racks. Many Boat and Ship Models/Boats-Sail received ad-hoc refits at advanced bases, mounting such light guns as Army Air Forces 37mm aircraft guns and even Japanese 23mm guns. Some PTs later received rocket launchers.
