Patrol Torpedo Boats (PT Boats) were used in all theaters of war in World War II, normally armed with a least four torpedoes and a number of machine guns and cannons.
In Call of Duty: World at War, in the campaign mission "Black Cats", several Allied ships are sunk by Japanese Zeros as the player needs to protect the PBY Catalina from being destroyed by PT Boats in the area. 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. During World War II, American PT boats engaged enemy destroyers and numerous other surface craft, ranging from small boats to large supply ships. Other entries in the competition were three boats built by Andrew Jackson Higgins of Higgins Industries in New Orleans.
The results of the competition found that none of the boats, as built, was up to the necessary performance specifications identified by the Navy. PT-26, -30, -31, -33: Same as PT-20, except with standard propellers and without special strengthening. The Elco Naval Division boats were the largest in size of the three types of PT boats built for the Navy used during World War II.
Even though only half as many Higgins boats were produced, far more survive (seven hulls, three of which have been restored to their World War II configuration), than the more numerous Elco boats, thus seemingly demonstrating their superior construction. Frank Pembroke Huckins and his innovative Quadraconic hull helped convince the Navy Board of Inspection and Survey to accept the PT designs. During World War II, the Vosper Boat Company of Great Britain arranged for several boatyards in the U.S. With accommodation for three officers and 14 enlisted men, the crew varied from 12 to 17, depending upon the number and type of weapons installed. The hull shape of a PT boat was similar to the "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. As a testament to the strength of this type of construction, several PT boats withstood catastrophic battle damage and still remained afloat. In 1943, an inquiry was held by the Navy to discuss planing, hull design, and fuel consumption issues, but no major modifications were made before the end of the war. Occasionally, some front line PT boats received ad hoc up-fits at forward bases, where they mounted such weapons as 37mm aircraft cannons, rocket launchers, or mortars.
The culmination of larger-bore cannons resulted in the installation of the 40mm Bofors gun[9] on the aft deck. Sometimes PT boats used depth charges as a last-ditch confusion weapon to scare off pursuing destroyers. The effectiveness of PT boats in the Solomon Islands campaign, where there were numerous engagements between PTs and capital ships as well as against Japanese shipborne resupply efforts dubbed "The Tokyo Express" in "the Slot", was substantially undermined by defective Mark 8 torpedoes. Throughout World War II, PTs operated in the southern, western, and northern Pacific, as well as in the Mediterranean Sea and the English Channel. The efficiency of the PT boats at sinking the Japanese supply barges was considered a key reason why the Japanese had severe food, ammunition, and replacement problems during the New Guinea and Solomon Island Campaigns, and made the PT boats prime targets for enemy aircraft. To accomplish the task, PTs in the Mediterranean and the Pacific (and RN and RCN MTBs in the Mediterranean) installed more and heavier guns which were able to sink the barges. Though their primary mission continued to be attack on surface ships and craft, PT boats were also used effectively to lay mines and smoke screens, coordinate in air-sea rescue operations, rescue shipwreck survivors, destroy Japanese suicide boats, destroy floating mines, and to carry out intelligence or raider operations. Although they did have a small refrigerator on board, PT boats lacked the larger capacity refrigerators of larger ships to store meat, milk, butter, and eggs, so crews depended on the ingenuity of their cook, who might also be quartermaster and signalman, and what he could do with sandwiches, Spam, Vienna sausage, beans, and orange marmalade. In 1944, several Higgins 78-foot (24 m) boats (PT222, PT-283, PT-284, PT-285, and PT-282) were converted, releasing PT-59, PT-60, and PT-61 for transfer back home to the Motor Torpedo Boat Squadron Training Command (MTBSTC) school in Melville, Rhode Island for use in training in hull repair techniques.
Life magazine published an article about the PT boat captains in the battles off Guadalcanal, featuring the exploits of Lieutenants "Stilly" Taylor, Leonard A. Other PT boats gaining fame during the war were PT-363 and PT-489, the boats used by Lieutenant Commander Murray Preston to rescue a downed aviator in Wasile Bay,[16] off Halmahera Island, for which Preston was awarded the Medal of Honor.
He has a number of interesting period photos both in the Mediterranean and Pacific Theaters. This was mainly due to the diverse combat and tactical roles these boats were called upon to perform. Doyle, in level Sicily 2, use a PT Boat armed with automatic cannon to escape from an Axis bunker in Capo Murro di Porco, destroying several German PT Boats along the way. PT boats also operated as gunboats against enemy small craft, such as armored barges used by the Japanese forces for inter-island transport.
At the same time the Philadelphia Navy Yard began construction of two other designs (PT-7 and PT-8), created by designers at the Navy Yard and the Navy Bureau of Ships. Sutphen of Electric Launch Company (Elco) and his designers (Irwin Chase, Bill Fleming, and Glenville Tremaine) visited the United Kingdom to see British motor torpedo boat designs.
These boats were PT-5 and PT-6 (built using government-required Sparkman and Stephens design, scaled to an overall length of 81 feet (25 m)) and then PT-6 "Prime" which was redesigned by Higgins personally using his own methods. 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. When these weapons were found to be successful, they were incorporated onto the PT boats as original armament.


Starting in mid-1943, the installation of this gun had an immediate positive effect on the firepower available from a PT boat. These 16 rockets plus 16 reloads gave them as much firepower as a destroyer's 5-inch (130 mm) guns. The cockpits of PT boats were protected against small arms fire and splinters by armor plate. They could adjust the depth charge setting to go off at 100 feet (30 m), and by the time it exploded the pursuing destroyer would be right above the explosion. The Japanese were initially cautious when operating their capital ships in areas known to have PT boats, since they knew how dangerous their own Type 93s were, and assumed the Americans had equally lethal weapons. 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. PT boat squadrons were supported by either PT boat tenders or PT boat bases which supplied the boat crews with hot meals cooked aboard the larger command's facilities. Bulkeley, carried General Douglas MacArthur in his escape from Corregidor Island, Philippines. Nikoloric, Lester Gamble, and Robert and John Searles; the article mentioned many boats in MTB Squadrons Two and Five (in particular, PT-36, PT-37, PT-39, PT-44, PT-46, PT-48, PT-59, PT-109, PT-115, and PT-123).
The accounts of night actions against German surface craft off the coast of Italy are really quite exciting. In the early days with the Elco 77' boats, armament compliment was minimal compared to the late war configuration. 251 · Opel Blitz · Model 94 Isuzu truck · Katyusha Rocket Launcher · ZIS-6 ·Jeep · Horch 1a · GMC CCKW · Schwimmwagen (cut) · M8 Greyhound (cut) · Wasp (cut) · Type 1 Ho-Ki (cut) · Sd. The PT boats used in World War II were built using the planing-type hull form developed for racing boats. The final competitor for the contract was Huckins Yacht Corporation, which came up with competing 70-foot (21 m) boat class designs.
This success in small-boat building was followed in the 1930s with 30-ft to 57-ft "Veedettes" and "Flattops", which were gasoline-powered boats that set the highest standard in a golden era of boating. Many Higgins boats were sent to the Soviet Union and Great Britain at the beginning of the war, so many of the lower-numbered squadrons in the U.S. The Elco and Higgins companies both used lightweight techniques of hull construction which included two layers of double diagonal mahogany planking utilizing a glue-impregnated cloth layer between inner and outer planks.
Kennedy's PT-109 (Elco) stayed afloat for 12 hours after she was cut in half by the Japanese destroyer Amagiri. Early PT boats (Elco PT20 through PT44) mounted Dewandre plexiglas-enclosed hydraulically operated rotating turrets.[5] Almost immediately after the attack on Pearl Harbor, the Dewandre turrets were replaced on the entire PT boat fleet with open ring twin mounts. One such field modification was made to Kennedy's PT-109, which was equipped with a single-shot Army M3 37mm anti-tank gun that her crew had commandeered; they removed the wheels and lashed it to 2x8 timbers placed on the bow only one night before she was lost.
Additionally, a few PT boats were equipped to carry naval mines launched from mine racks, but these were not in common usage. These engines were built by the Packard Motor Car Company, and were a modified design of the 3A-2500 V-12 liquid-cooled aircraft engine.
The final engine version, the Packard 5M-2500, (late 1945) had a larger supercharger, aftercooler, and power output of 1850 hp. In order to avoid return fire by the enemy ships, the PT boat could deploy a smoke screen using stern-mounted generators as they escaped and evaded the enemy ships.
The PT boats at Guadalcanal were given credit for several sinkings and successes against the vaunted Tokyo Express.
During the D-Day invasion, PTs patrolled the "Mason Line", forming a barrier against the German S-boats attacking the Allied landing forces.[12] They also performed lifesaving and anti-shipping mine destruction missions during the invasion.
The shallow depth meant Allied destroyers were unable to follow them due to the risk of running aground and the barges could be protected by an umbrella of shore batteries. The PT boat crews were usually located at the end of the supply chain, and as a result, they became proficient at finding "alternative means" of meeting their needs. Bulkeley was awarded the Medal of Honor for his operations in the Philippines before rescuing MacArthur.
Copp was the first boat, of a two boat squadron, to enter Manila Harbor in order to "test defenses" since the U.S. Hundreds of boats were deliberately stripped of all useful equipment and then dragged up on the beach and burned. I always enjoyed talking with him about his time serving in WWII in the Pacific, more of which I've written below. If you go to the After PT Boats page and scroll to the bottom there is a photo of my other PT Boat friend, Jack Madden, who served on Higgins boats in the Mediterranean off the coast of Italy in WWII.
The early boats carried 4 Mk-XIV torpedoes, and dual mounted 50cal machine guns in each of it's two turrets, with an occasional 30cal Lewis machine mount forward. Elco received the largest share of the contract with contracts for 350 boats, Higgins was awarded contracts for 199 boats, and Huckins was awarded a contract for 18 boats. This small-boat experience helped Elco obtain a contract for 10 boats based on the 70-foot (21 m) Scott-Paine Model PT boat. PT-323 (Elco) was cut in half by a kamikaze aircraft on 10 December 1944 off Leyte, yet remained floating for several hours.
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 3A-2500 was an improved version of the 2A engine used on the Huff-Daland XB-1 Liberty bomber of World War I vintage.


They 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.
PT boat crews would often beg, borrow, or barter with nearby ships or military units for supplies. This was done to minimize the amount of upkeep the Navy would have to do, since wooden boats require much continuous maintenance, and they were not considered worth the effort.
After the war Milt worked for many years in a machine shop in Teterboro, NJ and worked his way up to foreman.
Compare this with a typical late war configured boat with two to four Mk-VIII torpedoes, two dual 50cal machine guns in the turrets, a 40mm Bofors cannon mounted aft, a 37mm cannon far forward, flanked by two 20mm cannons and an assortment of other weapons such as deck mounted mortars, additional 30 and 50 caliber machine guns including two multiple 5" rocket launchers. Both types were designed to strike at larger warships with torpedoes, using relatively high speed to get close, and small size to avoid being spotted and hit by gunfire. The resulting PT boat designs were the product of a small cadre of respected naval architects and the Navy. Navy, and only about 50 were used by the Royal Navy, and most were passed to other countries. The overall result was an extremely light and strong hull, yet it could be easily repaired from battle damage at the front lines. PT-308 (Higgins) had her stern sheared off by a collision with PT-304 during a night mission in the Mediterranean on 9 March 1945 and yet returned to base for repairs. However, using the older 4M-2500 engines, increases in the weight of the boats due to more weaponry offset the potential increase in top speed.
At the front lines, it was not uncommon to see crewmen fish by aiming rifles or tossing grenades into the water near the boat.
PT-41 was the flagship of Motor Torpedo Boat Squadron Three (MTBRON 3), based in the Philippine Islands 1941–1942 (PT-41, ?31, ?32, ?33, ?34, ?35).
The boats also used a lot of high octane gasoline for their size, making them too expensive to operate for a peacetime navy.
He tried to retire early, but his employer valued him so much Milt was made an offer he couldn't refuse and he stayed on longer. Navy were used in the Battle for the Aleutian Islands (Attu and Kiska) as part of Squadron 13 and 16, and others (RON15 and RON22) in the Mediterranean against the Germans.
PT-167 (Elco) was holed through the bow off Bougainville on 5 November 1943, by a torpedo which failed to detonate; the boat remained in action and was repaired the next day. Later in the war, several more of these 20 mm cannons were added amidships and on the forward deck.
Having radar gave Navy PTs a distinct advantage in intercepting enemy supply barges and ships at night. Fuel consumption of these engines was phenomenal; a PT boat carried 3,000 gallons (11,360 liters) of 100 octane avgas. Eventually he did retire, but Milt missed having all the machine tools handy that would have helped him make home improvement and maintenance projects easier.
PT boats were much faster, smaller, and cheaper than conventional (displacement hull) vessels. This type of construction made it possible for damage to the wooden hulls of these boats to be easily repaired at the front lines by base force personnel.
He helped me a number of times drilling and removing broken bolts and studs from various automotive parts over the years. Five Elco Boats were manufactured in knock-down kit form and sent to Long Beach Boatworks for assembly on the West Coast as part of an experiment and as a proof of concept. Their aircraft roots gave them many features of aircraft engines, such as superchargers, intercoolers, dual magnetos, two spark plugs per cylinder, and so on.
The consumption rate for each engine at a cruising speed of 23 knots was about 66 gallons (250 l) per hour (200 gallons [760 l] per hour for all 3 engines). Milt also gave a lot to our lake community, teaching the kids how to sail, maintaining and repairing the sailboats at the end of the season, pitching in to help at barbecues and pancake breakfasts, and a variety of other projects over the years. Packard built the Rolls-Royce Merlin aero engine under license alongside the 4M-2500, but with the exception of the PT-9 prototype boat brought from England for Elco to examine and copy, the Merlin was never used in PTs.
However, at top speed, consumption increased to 166 gallons (628 l) per hour per engine (or 500 gallons [1,890 l] per hour for all 3 engines). We've missed him coming down to the docks to watch the sunsets in the evening, and sailing races during the Sundays in the summer after he gave up racing himself. Navy acceptance trials for every boat required it be able to demonstrate ability to achieve design speed of 41+ knots. He also was very active in his local bowling league, and continued bowling into his 90th year. Wartime conditions such as hull fouling and engine wear could sometimes cause the boats' top speed to be degraded until maintenance could be performed. He never complained, unless he was in extreme pain which he was in the last few months due to his hip. He had an easy smile and a very positive attitude and was well liked and respected in the neighborhood.
