This resulted in the November 1943 Miami test trial between two Higgins and two Elco boats, but no major additional modifications were made before the end of the war. This was done in thin material, easy to cut. The course started from the mouth of New London Harbor, to Sarah Ledge, then led around the eastern end of Block Island, then around Fire Island Lightship, finishing at Montauk Point Whistling Buoy. PT-728, a surviving Vosper boat built under license at the Annapolis Boat Yard in Maryland, was restored in Key West, Florida. PT-191 was one of the last boats in the first series (PTs 103-196)of the PT-103 Class. [40] It was used in the training squadron MTBRON4 in Melville, Rhode Island, during World War II until it was placed out of service 16 January 1946. Details on the boat's construction are given on page 357, MTB Manual, 1943. These features made it highly desirable due to the PT boat's ever-increasing requirement for increased firepower to deal effectively with the Japanese Daihatsu-class barges, which were largely immune to torpedoes due to their shallow draft. Later, rigorous testing performed on each design as well as changes in armament revealed limitations or problems that had to be fixed before they could meet required performance specifications. The race was a PT boat scramble in the South Pacific during World War II. While favorably received, Secretary of the Navy Josephus Daniels rejected the proposal since the US was not at war, but Hickman was advised to submit his plans and proposal to the British Admiralty, which was done the following month. Five 78-foot (24m) boats were assigned to Squadron 14 (PT-98 through PT-102) which was commissioned in early 1943; and ten boats assigned to Squadron 26 (PT-255 thru PT-264) which was commissioned in mid 1943. With the exception of the experimental PT boats, all U.S. PT boats were powered by three marine modified derivations of the Packard 3A-2500 V-12 liquid-cooled, gasoline-fueled aircraft engine. Listed in order from bow to stern, they are: Forepeak (Chainlocker), Forward Crew's Quarters/Galley, Officers Wardroom, Forward Tank Room/Head, Engine Room, Aft Tank Room/Head, Aft Crews Quarters and Lazarette . This Squadron saw action in the Solomon Islands, Guadalcanal, and Funafuti. PT boats also commonly carried between two and eight U.S. Navy Mark 6 depth charges in roll-off racks. As home to the National PT Boat Museum, Battleship Cove displays the world's largest collection of PT boat artifacts and memorabilia. by Thomas Fleming 2/22/2011. PT-105, an 80' Elco boat, under way. In June 1945 the squadron was shipped to the U.S. for refitting and transfer to the Pacific, but the war ended while still in New York. PT Boat Model Builder's PT Boat PT Boat Plan 10812 Type Model RC Scale Military. The performance specification was to achieve 40 knots with an operating radius of 275 miles at top speed (550 miles at cruising speed). Volume builders such as Beneteau and Sea Ray have now commissioned French and Italian design companies. The boat is owned by PT Boats, Inc., a World War II PT veterans organization headquartered in Germantown, Tennessee. When these weapons were found to be successful, they were incorporated onto the PT boats as original armament. Of the Elco boats, only three hulls (one restored) were known to exist as of 2016. PT boats were a variety of torpedo-armed fast attack craft used by the United States Navy in World War II to attack larger surface ships. Most probably due to the lateness in joining the PT boat program and unlike Elco and Higgins, the Huckins yard was never provided any government support to construct a larger facility prior to the war. In 1922, the US Navy reconsidered using small internal combustion engine powered torpedo boats. [9], The Elco 77-Footer Design Demonstrates:[9], The Huckins 72-Foot Design Demonstrates:[9], The Navy Yard Philadelphia 81-Foot Design Demonstrates:[9], The Higgins 81-Foot Design Demonstrates:[9], The Higgins 76-Foot Design Demonstrates:[9], The Board arrived at the following recommendations:[9], The Board also had the following opinion on structural sufficiency: "During the first series of tests (2124 July) the Huckins design (PT-69), the Philadelphia design (PT-8) and the Higgins design (PT-6) completed the open sea endurance run without structural damage. This article is about US Navy patrol torpedo boats in World War II. ELCO 80' PT - 596 TORPEDO BOAT. [9], Lastly, there was a demonstration of seakeeping qualities and hull strength by making a run at maximum sustained speed in the open ocean. Hampden. The 85-foot-long Mk VIs, which displace around 72 tons, have a main armament of two M242 Bushmaster cannons, the same gun found on the U.S. Army's Bradley Fighting Vehicles, in a pair of. Later in the war, several more of these 20mm cannons were added amidships and on the forward deck. U.S. Navy PTs were eventually fitted with Raytheon SO radar, which had about a 17nmi (20mi; 31km) range. This conference, including representatives from BuShips, BuOrd, MTBRONs, Interior Control Board, and CNO, recommended a series of comparative tests to evaluate what turned out to be five new designs of motor torpedo boats. Direct hits from Japanese guns could and did result in catastrophic gasoline explosions with near-total crew loss. (Here are selected photos on this topic, but full relevance is not guaranteed.) Towards the end of the war, beginning in 1945, PTs received two eight-cell Mark 50 rocket launchers,[20] launching 5in (130mm) spin-stabilized flat trajectory Mark 7 and/or Mark 10 rockets[21] with a range of 11,000 yards (10,000m). This is the PT Boat listing page, here you can download the plan, article and see the main thumbnail and extra images. Some PT boats served during the Battle of Normandy. The tour starts from Bow and works back to see entire boat with detail views of each weapon and piece of equipment. Ability to make a maximum sustained speed of 30.7 knots; maximum speed 33.9 knots with light ordnance load. Originally conceived as anti-ship weapons, PT boats were publicly credited with sinking several Japanese warships during the period between December 1941 and the fall of the Philippines in May 1942[23] even though the Navy knew the claims were all false. A common characteristic of this type of contoured hull is the "rooster tail" in the wake. [note 1] Six boats completed the trial, while three withdrew: PT-33 suffered structural damage off Block Island; PT-70 was damaged by loose copper ingots; and MRB developed engine trouble at the start of the run.[9]. The 1938 United States Navy PT, which has been restored and adapted to Coast Guard Standards, is a durable boat that was originally used in the US fleet for a period of time. General visitors are not allowed inside the boat in order to help preserve her historic integrity. Beginning in mid-1943, some boats were fitted with one or two .30 cal Browning machine guns on the forward torpedo racks on pedestal mounts. [23] The Mark 3 and Mark 4 exploders were not subject to the same problems as the Mark 6 exploders on U.S. submarines' Mark 14 torpedoes. Bass Boats. Finish adequate. . She was transferred back to the United States in April 1945. The American side of the PT boat ("Patrol Torpedo") wars of World War 2 are primarily remembered through the exploits of the men governing their ELCO PT systems against the vessels of the mighty Japanese Navy. Hundreds of boats were deliberately stripped of all useful equipment and then dragged up on the beach and burned. [36] It was relaunched in March 2017,[37] and the museum is booking rides on Lake Pontchartrain on Saturdays, or static tours other days of the week.[38]. PT-766 is an 80-foot (24m) Elco boat that is a private yacht ("Finished Business") located in Washington D.C. She represents the final class of Elco's with significant updates to the superstructure and radar and was intended for MTBRON 44, but was cancelled due to the end of the war. This is because the 1st and only training facility for PT Boat skippers and crews was in Melville, RI part of the town Portsmouth, RI. In spring of 2012, PT-728 was acquired by the Liberty Aircraft Museum of Port Clinton, OH for further restoration. .. K. sdaf . PT-9 was to serve as the prototype for all the early Elco PT boats. The last of her type to be constructed, she was nicknamed Tail Ender. He also granted permission for Elco, Higgins, and the Philadelphia Navy Yard to use his patented laminated keel, which increased hull strength, although neither Elco nor Higgins ever chose to use it on their boats. length would be sufficiently seaworthy", so Hickman built and launched his own privately financed 41-foot (12m) Sea Sled capable of carrying a single 18-inch Whitehead Mark 5 torpedo. Motor Torpedo Boat Squadron 22, or RON22, was transported to the combat theater aboard the USS Merrimack. PT-728 was acquired by Fleet Obsolete and moved to Kingston. All except the Huckins (PT-69) completed the run. Growing up in Rhode Island at a young age I knew what a PT Boat was; especially famous one's like Kennedy's PT 109. It's the only place you can see both PT boats at once. After the war, the ex-PT459 was cut down to 65ft (20m) and highly modified into a sightseeing boat and fishing trawler. Robert McFarlane. Primary anti-ship armament on the standard PT boat was four 21-inch Mark 8 torpedoes, each had a 466-pound (211kg) TNT warhead and had a range of 16,000 yards (15,000m) at 36 knots (67km/h). Wood Boats. [5], The final PT boat design competitor was Huckins Yacht Corporation of Jacksonville, Florida. This contract for C-250 ended up going to Greenport Basin and Construction Company, of Greenport, NY. Unlike the actual "planing hull" Huckins, which planed at 10-11 knots, the Elco and Higgins PT boats were intended to plane at higher speeds (PT 71 and PT-103 classes at around 27 knots, and the PT-265 and 625 classes at around 23 knots). Structural weaknesses resulting in fracture of bilge stringers. Some boats carried a 20mm (0.79in) Oerlikon cannon. [23] They also performed lifesaving and anti-shipping mine destruction missions during the invasion. PT 48 is the only remaining 77' Elco PT-Boat and a member of the heroic WWII "Mosquito Fleet". Vincent, before he became a priest, was the quartermaster on the much more seaworthy PT 60. The handcrafted Huckins PT was produced at their civilian facility at a speed of one per month. The larger punch of the 37mm round was desirable, but the crews looked for something that could fire faster than the single-shot army anti-tank weapon. [9], Due to the problem with ingot loading, a 185nmi (343km; 213mi) trial with the PTs fully fitted out was conducted on 12 August 1941. As more PTs were fitted with dependable radar, they developed superior night-fighting tactics and used them to locate and destroy many enemy targets. The other competitors had copper ingots added topside (mostly in the turrets) to make up the difference. SKILL 5. The 5M-2500 introduced in late 1945 had a larger supercharger, aftercooler, and increased power output of 1,850hp (1,380kW). Mark 8 torpedoes had a range of 16,000 yards (14,630m) at 36 knots (67km/h; 41mph). 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. The key to making LED boat lights look great, is placement. Of those proposals submitted, Three 54-ft designs and five 70-ft designs were of interest and the designers were asked to submit more detailed plans for both the 54 and 70 foot boats by no later than the 7th of November 1938. In the USN they were organized in Motor Torpedo Boat Squadrons (MTBRONs).[1]. Following the competition, contracts were placed for construction of boats: May 25, 1939, to Higgins Industries for two boats (PT5 and PT6) of the Sparkman and Stephens design, scaled up to an overall length of 81 feet; June 8, 1939, to Fogal Boat Yard (PT-1 and PT-2) and Fisher Boat Works (PT-3 and PT-4) for the Crouch design; to the Philadelphia Navy Yard (PT-7, PT-8) for 81-foot boats designed by the Bureau of Ships. "[9], The Board results provided very important benchmarks in the infancy of PT boat development. In 1938, the U.S. Navy renewed their investigation into the concept by requesting competitive bids for several different types of motor torpedo boats, but excluded Hickman's Sea Sled. [31], At the end of the war, almost all surviving U.S. PT boats were disposed of shortly after V-J Day. On 11 July 1938 the Navy issued multiple 'notice of competitions' for proposals of design of four separate types of boat: a 165-foot subchaser, a 110-foot subchaser, a 70-foot motor torpedo boat, and a 54-foot motor torpedo boat.
