What size were PT boats?
80-foot long
In the later years of the war the U.S. Navy standardized the design and construction of the PT boat. Two basic and distinctly different types of PT Boats were built for combat with the predominant PT, the 80-foot long “Elco” boat, and the slightly smaller 78-foot long “Higgins” boat.
What engine did the PT boats use in WW2?
The U.S. Navy used the Packard V-12 Marine Engine (4M-2500) in all U.S. Navy World War II PT boats. The design was based on the 1925 Liberty Aircraft Engine, which had been converted for use in racing. Throughout the war the Packard engine underwent a number of key updates and modifications.
How many PT squadrons were there in WW2?
Forty-three PT squadrons, each with 12 boats were formed during World War II by the U.S. Navy. PT boat duty was very dangerous and the squadrons suffered an extremely high loss rate in the war. In 1938 the US Navy sponsored a design competition to small boat builders with a challenge to create a highly mobile attack boat.
Why was the pt8 not used in WW2?
PT-8 (built at Philadelphia Naval Shipyard) in Louisiana was built entirely from aluminum but did not pass the speed acceptance criteria for use as a PT boat for the U.S. Navy due to its weight. She was reclassified as a harbor patrol boat (YP 110) for the duration of the war.
How much horsepower does a PT boat engine have?
The first engines developed 1,200hp, but improved versions with higher boost levels nominally made 1,500hp. Packard built 14,000 marine engines during the war, three of which went into each of the Navy’s 768 PT boats, two astern and one amidships for better service access.
