The 5M-2500 introduced in late 1945 had a larger supercharger, aftercooler, and increased power output of 1,850hp (1,380kW). [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. Some PT boats served during the Battle of Normandy. The cockpits of PT boats were protected by armor plate against small arms fire and splinters. They were powered by aviation fuel and three powerful engines. PT-305 was cut down to 65 feet (20m) for use as an oyster seed boat in Crisfield, Maryland. One captured Japanese soldier's diary described their fear of PT boats by describing them as "the monster that roars, flaps its wings, and shoots torpedoes in all directions."[27]. 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). She is available for public viewing, and has portions of her hull cut away to display the cramped interior of the crew's quarters. In April 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. Model Dim. On 11 October 1940, an agreement between the Navy and Huckins was finalized. [48] The other six boats are in various states of disrepair, sunk or scrapped. The nucleus of this collection are PT Boats 617 and 796, the world's only restored pair of PTs on public exhibition. Space available for two 21" torpedo tubes and ten 300-pound (140kg) depth charges. Later that same year, Higgins was to build PT-70 (at their own expense) that incorporated slight improvements over PT-6 Prime. Boat Decor. 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. The M4/M9 37mm auto cannon had a relatively high rate of fire (125 rounds per minute) and large magazine (30 rounds). FineScale Modeler reviews the 1/72 scale plastic model PT boat kit. A model of PT Boat 109, presented to President John F. Kennedy by representatives from the Washington International Boat and Sport Show, sits on display in the Fish Room, White House, Washington, D.C. [See also MO 63.1212, u201cModel of PT 109.u201d] Elco boats were found to pound heavily and confirmed previous reports of crew discomfort. PTs would usually attack at night. The vessel was sold in 1952 to Otto Stocker who operated the "Sightseer" as an excursion vessel from Otten's Harbor in Wildwood, New Jersey. For the 1962 movie PT-109, several 82-foot (25m) USAF crash rescue boats were converted to resemble 80-foot Elcos when the few surviving boats were found to need too much work to make them seaworthy for use during the film. PT boat interior S Stephen Borona 642 followers More information PT boat interior Naval History Military History E Boat Plywood Boat Plans Radio Controlled Boats Boat Interior Military Weapons Military Memes Model Boats More information . Starting in mid-1943, the installation of this gun had an immediate positive effect on the firepower available from a PT boat. Higgins developed the small and fast 70-foot (21m) Higgins Hellcat, which was a slight variation on their original hull form, but the Navy rejected them for full production due to increased fuel consumption and other considerations. [5] Maneuverability satisfactory except for a large turning circle of 432 yards (395m). The hull shape of the Elco and Higgins PT boats were similar to the contoured "planing hull" found in pleasure boats of the time (and still in use today): a sharp V at the bow softening to a flat bottom at the stern. [16][17] Another automatic weapon commonly mounted on PT boats was the 20mm Oerlikon cannon. 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. was assigned during the war to MTBRON 22, and saw action against the Germans in the Mediterranean Sea. [9], Lastly, there was a demonstration of seakeeping qualities and hull strength by making a run at maximum sustained speed in the open ocean. Later in the war, several more of these 20mm cannons were added amidships and on the forward deck. [5], By September 1938 the U.S. Navy had received a total of 24 design proposals for the small boat and 13 design proposals for the larger 70-footer. Box Dim. PT-305 was looking good, with a lifeboat on her foredeck, jauntily tied fast over one-half of her charthouse. U.S. Navy PT boats were organized into motor torpedo boat squadrons (MTBRONs). They were assigned to specific outposts in the Panama Canal Zone, Miami, Florida, the Hawaiian Sea Frontier at Pearl Harbor and Midway, and a training center in Melville, Rhode Island. As a result, two types 45-foot (14m) and 55-foot (17m) of British Royal Navy Coastal Motor Boats were obtained for testing. The Higgins 76-footer (PT-70) completed the entire run but also suffered structural failures, attachments between planking and web frames pulling loose, and deck fastenings in the neighborhood of engine hatches showing extensive failures. 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. The PT boat design was also exported after the end of the Second World War as an unarmed air-sea rescue launch for use by the South African Navy. [23] Enemy forces would use searchlights or seaplane-dropped flares to illuminate fleeing PT boats. 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. Fr. In the USN they were organized in Motor Torpedo Boat Squadrons (MTBRONs).[1]. It has been released as PT 207 and PT 212 and maybe others. The installation of larger-bore cannons culminated in the fitting of the 40mm Bofors gun[18] on the aft deck. PT 48 is the only remaining 77' Elco PT-Boat and a member of the heroic WWII "Mosquito Fleet". It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively . It covers PT boat hull design and construction, and provides hull test data as well as detailed analysis of the various PT boat designs.[13]. Technically the stem post ends at frame 9 and the keel begins. While serviceable naval vessels in their own right, the group lacked the performance and capabilities that the USN sought. Structural weaknesses caused failures in transverse bottom framing, separation of side planking from framing and extensive failures of deck fastenings. PT 109 boat model. In the interval between the first and second test periods the PT-70 was repaired and an effort made to eliminate the causes of the structural failures. Their role was replaced in the U.S. Navy by fast attack craft. Accelerometers were again installed in the pilot house of each boat, but the readings were incomplete because the violent motion of the boats made observations extremely difficult and in some cases necessitated abandonment of the observing stations. Crews varied from 12 to 17, depending upon the number and type of weapons installed. A PT boat carried 3,000 US gallons (11,400L) of 100 octane aviation fuel, enough for a 4M-2500 equipped boat to conduct a maximum 12-hour patrol. PT Boat Interior Layout. A 78-foot (24m) Higgins, PT-309 ("Oh Frankie!") Wood Boats. In John Ford's 1945 war film, They Were Expendable, two 80-foot (24m) Elcos were used during filming along with four former MTBRON 14 78-foot Huckins.[50]. The handcrafted Huckins PT was produced at their civilian facility at a speed of one per month. Direct hits from Japanese guns could and did result in catastrophic gasoline explosions with near-total crew loss. the plywood landing craft vehicle personnel (LCVP) used so successfully in the beach landings at Normandy in the Atlantic and the island-hopping campaign in the Pacific produced 199 78ft (24m) boats of the PT-71/PT-235, PT-265 and PT-625 classes. PT 617 was built too late to serve in WWII. Measure 31/5P - This scheme utilized Navy Green and Ocean Green. Since both the Japanese in the New Guinea area and the Germans in the Mediterranean had lost numerous resupply vessels to Allied air power during daylight hours, each attempted to resupply their troop concentrations by using shallow draft barges at night in very shallow waters. (photosinhouse16@gmail.com) The first class was for 54-foot (16m) boats, and the second class was for 70-foot (21m) boats. [citation needed] Crews feared attack by Japanese seaplanes, which were hard to detect even with radar, but which could easily spot the phosphorescent wake left by PT propellers. Space available for four 21" torpedo tubes. The brand new Trawler Forum Burgee is now available for order. Maneuverability satisfactory, turning circle not determined photographically, estimated 300 yards. PT-9 off Washington DC (1940) PT-1: This very first 58ft Experimental MTB, laid down 12 July 1939 by Fogal Boat Yard in Miami, Florida to answer the USN called. These were to be provided to the Dutch forces under Lend Lease but were re-requisitioned to the USN as PT 368371 after the fall of the Netherlands to German forces. A hangar-style indoor display houses the Elco PT boat (PT-617) and Higgins PT boat (PT-796). The boatyards were located in Annapolis, Bristol, City Island, Miami, and Los Angeles. Initially, only a few boats were issued primitive radar sets. Mark 8 torpedoes had a range of 16,000 yards (14,630m) at 36 knots (67km/h; 41mph). We promise fish will be wanting to jump aboard your boat! 2. This gun was served by a crew of 4 men, and was used against aircraft targets, as well as shore bombardment or enemy surface craft. 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. She was sold several times, and moved to Kingston, NY for possible restoration. The last of her type to be constructed, she was nicknamed Tail Ender. The primary anti-ship armament was two to four Mark 8 torpedoes, which weighed 2,600 pounds (1,179kg) and contained a 466-pound (211kg) TNT warhead. Of the nearly 400 small, fast, versatile wooden Patrol Torpedo boats which were built around WWII, only a handful survive to this day. Cost to the Government fully equipped $263,500. However, the USN held two major designs as their standard PT boat and this included the ELCO 80-footer and the Higgins 78-foot. Date October 1981 Finish adequate. Please help update this article to reflect recent events or newly available information. Remarkably, the PT486 was sold to the son of the original owner, Capt. After the initial competition, in late 1939, the Navy contracted Elco to build 11 copies of PT-9. [44] After the war ended PT-796 was used in the Key West/Miami area for experimental purposes. The winning design proposals would each receive a prize of $15,000 with $1500 for designs that reached the final part of the competition each to be given out on 30 March 1939. 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. A PT boat (short for patrol torpedo boat) was a motor torpedo boat used by the United States Navy in World War II. Acid-resisting black Copperoyd bottom paint Canvas preservative dyes (blue, gray or green) Deck Blue (20-B) Deck Green (20-G) [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. During World War I Italy, the US, and UK developed the first high-performance gasoline-powered motor torpedo boats (often with top speeds over 40kn (74km/h)) and corresponding torpedo tactics, but these projects were all quickly disbanded after the Armistice. Ability to make a maximum sustained speed of 31.4 knots; maximum speed 34.3 knots with heavy ordnance load. She was preparing to leave her cozy berth inside the corrugated steel boathouse. [26] [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-658 is floating on the north bank of the Willamette River, housed in a custom-built boathouse in Portland, Oregon at the P T-658 Heritage Museum located at the Swan Island Industrial Park. 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 first three of the new design (PT-95 through PT-97) were initially kept in the Jacksonville area for testing, resulting in several important modifications to the overall design (these boats were later assigned to Squadron 4 in 1942). She was attached to Squadron 40 in the Philippines but arrived too late to see action. The other two Elco boats, PT-30 and PT 23 (standby boat), followed PT-31, placing before PT-69. Now located in a New Jersey boatyard in awaiting restoration.[46]. That the ordnance installation of future motor torpedo boats consist of two torpedo tubes, machine guns and depth charges. Focus and explanation of E PT Boat. The 80' Elco Patrol Torpedo boat was the last of the wartime PT boat development. The quality of the restoration was extremely high, and the boat is on display inside a weatherproof building, on blocks out of the water. Many PT boats became famous during and after World War II: According to the book "At Close Quarters: PT Boats in the United States Navy"[30] 99 of the 531 PT boats that served during World War II were lost to various causes. Maneuverability satisfactory with a turning circle of 368 yards. Some 200 US gallons (760L) an hour were consumed at a cruising speed of 23 knots (43km/h), increasing to 500 US gallons (1,900L) per hour at top speed. Yacht Interior. PT boats operated in the southern, western, and northern Pacific, as well as in the Mediterranean Sea and the English Channel. The newly designed 80ft (24m) Elco Naval Division boats were the longest of the three types of PT boats built for the Navy used during World War II. Carrollton: Squadron Signal, 1994. Boat Stuff. These first generation torpedo boats rode low in the water, displaced up to 300 tons, and had a top speed of 25 to 27kn (46 to 50km/h). [22] Only the British built PT-9 prototype boat brought from England for Elco to examine and copy featured a Merlin. This is the definitive source on US PT Boats and impact they had on history. The first Higgins boats for the U.S. Navy were used in the battle for the Aleutian Islands (Attu and Kiska) as part of Squadrons 13 and 16, and others (MTBRON15 and MTBRON22) in the Mediterranean against the Germans.

United States PT Boats of . The Wild Places. In the August 1943 engagement in which PT-109 was lost, fifteen boats shipping 60 torpedoes fired over half without a single one hitting an enemy vessel. 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). Hundreds were built by Elco and other companies from 1942-'45, with most of them sent to the Pacific theater. The larger boat proposal was not to exceed 80 feet and was to carry at least two 21-inch torpedoes, four depth charges, and two .50-cal machine-guns. Placed in service too late to take part in World War II, PT-796 saw temporary . [4] The larger boat was used for experiments until 1930. PT-796 ("Tail Ender") is a 78-foot (24m) Higgins. The accelerometers ranked the boats as follows: first was the Philadelphia Navy Yard PT-8 with the least pounding, second was the Huckins PT-69, third was the Higgins PT-6, and last were the Elco 77-footers. Of the more than 500 small, fast, versatile wooden Patrol Torpedo boats which were built during WWII, only a handful survive today. The Admiralty representative for this sea sled demonstration was Lieutenant G.C.E. [citation needed].
