# Motor Torpedo Boat Squadrons

Motor Torpedo Boat Squadrons were United States Navy Patrol, Torpedo, (PT boat) squadrons commissioned for operation during World War II. During the war 44 Motor Torpedo Boat Squadrons were commissioned. At the end of the war all 44 Squadrons were decommissioned. In April 1940 the US Navy designed the idea of PT boat squadrons. PT boat squadrons would have 12 boats each with its own commanding officer. The PT boat captains, called officers-in-charge and the boat's crew in the squadron could move from boat to boat within their squadron, depending on availability of boats and crews. Boats could also be transferred from squadron to squadron on an as needed based or to replace losses. A total of 690 PT boats were built between 7 December 1941 and 1 October 1945.

## History

In 1938 the US Navy put out proposal requests for a boats that would be fast, strong and heavily armed, a PT Boat design competition was held. From the designs, different shipyards were give contracts for the construction of boats. The Prototype PT boats were evaluated and tested, one test was the Plywood Derby. From these test Elco Naval Division and Higgins Industries were picked. The Test were done by the first two Motor Torpedo Boat Squadrons one and two. With the new boats a new base was built, to train the new Squadrons at Melville, Rhode Island on Narragansett Bay, the Melville Motor Torpedo Boat Squadrons Training Center. Motor Torpedo Boat Squadron 4 was based at the Training Center to train the new Squadrons. The Squadron Training Center's nickname was Spect Tech, after its first commander, Lieutenant commander William C. Specht. Squadrons were send to the Pacific War, which saw the most action; the Pearl Harbor PT Boat Base, the Aleutian campaign; Panama Sea Frontier, based at the PT Boat Base Taboga Island; North African campaign, the Mediterranean Sea, English Channel; and the Mediterranean Sea, working with English troops. Of the many PT boats in Motor Torpedo Boat Squadrons few survived. At the end of the war PT boats were not needed and they used vast amount of high octane fuel in their large three Packard 4M-2500 engines, so almost all were scrapped at the end of the war. Only about 16 PT Boats have survived from being scrapped. The 16 PT boats vary from running restored boats to just hulls.
