gato class submarine blueprints

Twenty of the 52 U.S. submarines lost in World War II were of this class, plus Halibut, a damaged boat that returned to the U.S., but was considered a constructive total loss and not repaired. [42], The Regulus nuclear cruise missile program of the 1950s provided the U.S. Navy with its first strategic missile capability. This time, she experimented with refueling seaplanes at sea, which was potentially important, as refueling the nuclear-capable Martin P6M Seamaster at sea could improve the Navy's strategic strike capabilities. Their principal weapon was the steam powered Mark 14 torpedo in the early war years, with the electric Mark 18 torpedo supplementing the Mark 14 in late 1943. [4] Thus, in some references they are listed with that class. [10], By 1931, the experimental phase of fleet submarine development was over and the Navy began to make solid progress towards what would eventually be the Gato class. They were also armed with one 3 inch deck gun and a variety of smaller anti-aircraft weapons. [1] The class was very successful in sinking Japanese merchant ships and naval vessels: the top three US submarines in tonnage sunk were Gatos, along with three of the top seven in number of ships sunk. They could be added without impact to the boat's war fighting abilities due to the extra room of the big fleet boat. Silversides, Flasher, and Wahoo were 3rd, 4th, and 7th place on the list for the number of ships sunk. Answer (1 of 5): How to get in and out of a Gato Class submarine: Forward to aft: 1. Acknowledging this limitation, the Bureau designers incorporated a negative (sometimes called a "down express") tank into the design which provided a large amount of negative buoyancy at the start of the dive. [11], Timing, however, conspired against the actual use of these boats in their assigned role. Nov 18, 2006. Dark Roasted Blend: Cramped Efficiency: Inside a Submarine source. These were originally intended to be Balao-class subs and were assigned hull numbers that fall in the middle of the range of numbers for the Balao class (SS-285 to SS-416, SS-425, and S-426). In addition, the government purchased an old foundry downstream from the main yard, constructed ten slipways and turned the yard over to Electric Boat. Not only did the crew benefit from AC, but so did the equipment. Fighter; Bomber; Boat airliner An improvement on the earlier Gato-class, the boats had slight internal differences. Tullibee was an attempt to develop a slow but ultra-quiet nuclear-powered SSK equivalent; no others were built due to her unexpectedly high cost relative to the more capable Thresher, and the SSK mission was folded into the regular attack submarine role. (1,131) $129.95. Fortunately, the same capabilities that would have enabled these submarines to operate with the fleet made them superbly qualified for their new mission of commerce raiding against the Japanese Empire.[12][13]. [46], With the retirement of the Regulus missile system in 1965, Tunny was converted into a troop transport in 1966. The Balaos were virtually identical to the Gatos, but design changes to facilitate rapid building resulted in greater structural strength and an increase in diving depth from 300ft (91m) to 400ft (122m). They would be converted again in 1955 to a higher GUPPY level. Manitowoc had already completed their allotted production run of Gatos and could not switch over to the Balao design until Electric Boat supplied them with the plans. The large bulky original configuration proved to be too easy to spot when the boat was surfaced; it needed to be smaller. Frequent breakdowns and utter unreliability had destroyed these engines' reputation with the Navy and they were all removed at the first opportunity and replaced by GM-Winton 16-278A V-type diesels. A Gato Class had a length of 311 feet (95 meters), a draft of 16-17 feet (4.9-5.1 meters), and a beam of 27 feet ( 8.3 meters) in its design. Decorate your laptops, water bottles, notebooks and windows. They could be added without impact to the boat's war fighting abilities due to the extra room of the big fleet boat. They were lengthened by 24 feet (7.3m) to provide additional space for an air control center and had powerful air-search and height-finding radars installed, with the after torpedo room converted into an electronics space with torpedoes and tubes removed. The government-owned shipyards (Portsmouth Naval Shipyard and Mare Island Naval Shipyard) began to make the transition to the new Balao design in the summer of 1942. Began to appear in early 1944. dietzer, Aug 23, 2013 #5 Beaver 2020 Rookie of the Year Admiral (Supporter) Joined: Apr 12, 2013 Posts: 3,425 Location: Central PA I have plans for the USS South Dakota, Lexington, Essex and the USS Iowa. This is stated on the official [] At the start of the war, these boats could go from fully surfaced to periscope depth in about 4550 seconds. The USS Wahoo (SS-238) was a Gato class submarine. Although a point of concern, the turning radius was still acceptable. In this role, the boats were rendered incapable of diving and had their propellers removed. Unfortunately, the HOR company ran into severe design and manufacturing problems and these engines proved to be operational and maintenance nightmares. [40] Japan received one (Mingo), Brazil two (Muskallunge and Paddle), Greece two (Lapon and Jack), and Turkey two (Guitarro and Hammerhead). White or transparent. Her Regulus hangar became a lockout chamber for UDT, SEAL, and Marine Force Recon teams in the Vietnam War. The Gato-class submarines were a class of seventy-seven American submarines used during World War II. -class cruiser. Due to a stunted research and development phase in the Depression era 1930s, and in great part due to the arrogance and stubbornness of the Navy's Bureau of Ordnance, the "wonder weapon" Mark 14 proved to be full of bugs and very unreliable. These were originally intended to be Balao-class subs and were assigned numbers that fall in the middle of the range of numbers for the Balao-class (SS-285 to SS-416 & 425426). High humidity generated by tropical waters will quickly condense and begin dripping into equipment, eventually causing electrical shorts and fires. Two Gatos, Flying Fish and Grouper (previously the prototype hunter-killer boat) were assigned to these duties and proved to be key players in the development of new sonar capabilities. Additional antiaircraft guns included single 40mm Bofors and twin 20mm Oerlikon mounts, usually one of each. Although a point of concern, turning radius was still good enough to be acceptable. [42][46][47], Guavina was converted under SCB 39 to a SSO in 1950 to carry fuel oil, gasoline, and cargo to amphibious beachheads. The superstructure that sat atop the pressure hull provided the main walking deck when the boat was surfaced and was free-flooding and full of water when the boat was submerged. Scale. Without changing the construction or thickness of the pressure hull steel, they decided that the Gato-class boats would be fully capable of routinely operating at 300 feet, a 50-foot (15m) increase in test depth over the preceding classes. By the end of 1941, 33 Gato keels had been laid. The entry sheet said it was an out of the box build but in my opinion, it goes far beyond that. The box measures 36x11x6" and it weighs 6 lbs. FOUND A BOX so now . Many targets in the Pacific War were sampans or otherwise not worth a torpedo, so the deck gun was an important weapon. For the Mk 10 and Mk 12 type mines used in World War II, each torpedo could be replaced by as many as two mines, giving the submarine a true maximum capacity of 48 mines. At the end of World War II, the U.S. Navy found itself in an awkward position. USS Silversides SS-236, Gato Class Submarine, Revell 1:72 Scale, Built by Keith Scruton, Entered in the 2019 US IPMS Nationals - Keith Scruton entered his build of the Revell 1:72 scale Gato Class submarine, built as the USS Silversides SS-236. Secondly, the desire to incorporate new masts for surface and air search radars drove changes to the fairwater and periscope shears. Their most noteworthy characteristics included long range, habitability, good sea-keeping and powerful armament. The outer hull merged with the pressure hull at both ends in the area of the torpedo room bulkheads, hence the "partial" double hull. Gato Class Submarine: Laid down, 5 October 1940, at Electric Boat Co., Groton, CT.; Launched, 21 August 1941; Commissioned USS Gato (SS-212), 31 December 1941; Decommissioned, 16 March 1946, at New York Naval Shipyard; Placed in service as a Naval Reserve Training vessel at New York and later Baltimore. Do you want your video to appear on our website? This time she experimented with refueling seaplanes at sea, but this mission too was dropped after a few years and Guavina was decommissioned. Italy received two (Barb and Dace), which received the only GUPPY conversions given to Gato-class boats (Guppy IB). Two Gato-class boats (Grouper and Finback) received rudimentary conversions to radar pickets before the end of World War II, but were not used in this role. The bureau designers felt that if a crew of 6080 men were to be expected to conduct 75-day patrols in the warm waters of the Pacific, these types of features were vital to the health and efficiency of the crew. Acknowledging this limitation, the bureau designers incorporated a negative (sometimes called a "down express") tank into the design, which was flooded to provide a large amount of negative buoyancy at the start of the dive. Escape trunk located in the Forward Torpedo Room: Upper hatch to outside the ship, side door to outside companionway, lower hatch into the ship. Fortunately, the very same capabilities that would have enabled these submarines to operate with the fleet made them superbly qualified for their new mission of commerce raiding against the Japanese Empire[9], The Gato-class design was a near duplicate of the preceding Tambor- & Gar-class boats.

Bowing to pressure from the submariners in the Pacific, the Bureau eventually acknowledged the problems in the Mark 14 and largely corrected them by late 1943. Commissioned shortly after the U.S. entered World War II, the Wahoo, SS-238, was a Gato-class submarine and the "most storied boat in the fleet" at the time of its sinking, according to the Naval . [10], The Gatos were slow divers when compared to some German and British designs, but that was mostly because the Gatos were significantly larger boats. Surface ships refitted with powerful radar suites were put into service, but they proved vulnerable in this role, as they could be attacked as well, leaving the fleet blind. All in all, they conducted 27 war patrols, but could not claim any verified sinkings. These were in commission but classed as "in commission, in reserve", thus some were decommissioned and recommissioned on the same day to reflect the change in status, List of most successful American submarines in World War II, Fleet Submarine index page at Navsource.org, Dictionary of American Naval Fighting Ships, Buffalo and Erie County Naval & Military Park website, Description of GUPPY conversions at RNSubs.co.uk, GUPPY and other diesel boat conversions page (partial archive), Navsource.org fleet submarines photo index page, https://en.wikipedia.org/w/index.php?title=List_of_Gato-class_submarines&oldid=1078246209, PT 1952-1960; struck 1Mar 1960, sold for scrap, PT 1946-1960; struck 1Mar 1960, sold for scrap, SSK Jan 1951; AGSS 21 Jun 1958; struck 2Dec 1968, sold for scrap, Lost to Japanese surface attack, 8Nov 1944, Lost to unknown cause, possibly rammed by Japanese merchant ship, 30Jul 1942, PT 1948-1960; struck 1Jun 1960, sold for scrap, Lost, possibly to Japanese surface attack, 16Feb 1943, PT 1949-1954; struck 1Sep 1958, sold for scrap, Struck 1Sep 1958, sold for scrap 4 May 1959, Lost to Japanese surface attack, 18Jun 1945. Battle ship plans / small size boats. Unique Gato Class Submarine stickers featuring millions of original designs created and sold by independent artists. Alaska. The Gatoclass were a class of submarines built for the United States Navy and launched in 19411943 they were the first massproduction US submarine class of World War II. At the end of World War II, the USN found itself in an awkward position. They were used in a variety of missions, including attacking Japanese shipping lanes and providing support for Allied forces during the D-Day invasion of Normandy. The model is a 1/350 hobby Boss submarine of the gato class, the number 212 to be precise, I am assembling it and it looks really cute. This page was last edited on 26 October 2022, at 02:26. The Guppy modernization program of the late 1940s largely passed these boats by. Redesignated SSR and called the "Migraine III" conversion, these boats were only moderately successful in this role as the radars themselves proved troublesome and somewhat unreliable. Class overview; Name: Gato class: Builders: Electric Boat Company; Portsmouth Naval Shipyard I have formed a few discs from 3mm section which will form the bulkheads for want of a better name. The other boats in the program included Angler, Bashaw, Bluegill, Bream, Cavalla, and Croaker. The last two Gato-class boats active in the US Navy were the Rock and the Bashaw which were both decommissioned on 13 September 1969 and sold for scrap. Together with their near-sisters the Balao and Tench classes, their design formed the majority of the United States Navy's World War II submarine fleet. On Oct. 11, 1943, nearly a month into Wahoos seventh patrol, a multi-hour combined sea and air attack involving depth charges and aerial bombs sunk the submarine. Submarines then and now are never going to be very comfortable, but the Gato class featured: * air conditioning * refrigerated food storage * fresh water distillers * washing machines And last, but far from least: * individual . [17], The large size of these boats did negatively affect both surfaced and underwater maneuverability when compared to smaller submarines. [6][7], The Gato-class boats were considered to be 'fleet submarines', designed to operate as adjuncts to the main battle fleet, based on standard-type battleships since World War I. All of the Gatos (with one exception, Dorado) would eventually fight in the Pacific Theater of Operations. [2][25], Occasionally, some confusion arises as to the number of Gato-class submarines built, with some sources listing the total as 73, due to the transitional nature of the first four boats (SS-361 through SS-364) constructed under the second contract by the Manitowoc Shipbuilding Company of Manitowoc, Wisconsin. They were sent into drydock for the very first conversion, Pomodon from 25 October 1946 to 26 July 1947 and Odax September 1946-August 1947. Turrets: 12.8 in (330 mm) face, 5 in (130 mm) roof, 5.25-6 in (133-152 mm) side and 5.25 in (133 mm) rear. All in all they conducted 27 war patrols but could not claim any verified sinkings. This is due to the transitional nature of the first four boats (SS-361 to SS-364) constructed under the second contract by the Manitowoc Shipbuilding Company of Manitowoc, Wisconsin. I've begun work on my revell 1/72 scale Gato Class Submarine. High quality Gato Class Submarine inspired framed prints by independent artists and designers from around the world. While most of these boats were of the more capable Balao and Tench classes, some Gatos went overseas, as well. Gatos served in six different wars during the 1940s .

Concluding that this role did not require a fast or deep-diving submarine (this line of thought would quickly change with the advent of nuclear power), seven Gatos were converted to SSKs (hunter-killer submarines) between 1951 and 1953, joining three purpose-built K-1-class SSKs entering service at that time. Tunny was subsequently converted into a troop transport, her Regulus hangar becoming a lockout chamber for UDT and SEAL teams. The large, bulky original configuration proved to be too easy to spot when the boat was surfaced; it needed to be smaller. Only Barb and Dace received GUPPY conversions; these were austere GUPPY IB modernizations under project SCB 47A prior to their transfer to the Italian Navy. These exposed beams gave rise to the nickname "covered wagon boats". The army was heavily armed and led by the most heavily armed subs of the war. All the early boats were built with this mod and it lasted until about mid-1942. She could carry two of the missiles in a cylindrical hangar on the aft deck. The original rationale behind their design was that they were intended to operate as adjuncts to the main battle fleet. [42], The advent of the kamikaze demonstrated the need for a long-range radar umbrella around the fleet. USS Corvina SS-226.jpg 750 938; 86 KB. Enlisted men repair and check instruments aboard a submarine just returned to Pearl Harbor. Unfortunately, the HOR company ran into severe design and manufacturing problems, and these engines proved to be operational and maintenance nightmares. She could carry two of the missiles in a cylindrical hangar on the aft deck. Naval Mines, Fleet Submarine index page at Navsource.org, "GUPPY and other diesel boat conversions page", "Cold War Curiosities: U.S. Radar Picket Submarines", "Reserve Training Boats of the U.S. Flying Fish was decommissioned in 1954, but Grouper continued in the test role until 1968. Do you want to become partner with us? The only significant differences were an increase in diving depth from 250 feet (76m) to 300 feet (91m), and an extra five feet in length to allow the addition of a watertight bulkhead dividing the one large engine room in two, with two diesel generators in each room. However, in the summer of 1942, six new Gatos were assigned to Submarine Squadron 50 and sent to Rosneath, Scotland, to patrol the Bay of Biscay and to assist in the Operation Torch landings in North Africa. Surface ships refitted with powerful radar suites were put into service, but they proved vulnerable in this role as they could be attacked as well, leaving the fleet blind. http://www.navsource.org/archives/08/04idx.htm, United States Submarine Operations in World War II, Gato (SS-212) Construction Service Photos, http://www.history.ca/ontv/titledetails.aspx?titleid=152495, List of submarines of the United States Navy, List of submarine classes of the United States Navy, Articles incorporating text from Wikipedia, World War II submarines of the United States, Vietnam War submarines of the United States, 311ft 8in (95.00m) 311ft 10in (95.05m), 11,000 nautical miles (20,000km) surfaced at 10 knots (19km/h). [42], Eventually more advanced sonars were installed on the new nuclear boats: Tullibee, commissioned in 1960, introduced the bow-mounted sonar sphere. You also get the crests for many of the subs as they appeared post-war. This Unique Submarine Was Actually Built For German Navy In 1903. The Gato-class design, with a top range of 11,000 nautical miles (20,000 km), was a near-duplicate of the preceding Tambor- and Gar-class boats. The Mark 18 electric torpedo was a hastily copied version of captured German G7e weapons and was rushed into service in the fall of 1943. Grouper had all her forward torpedo tubes removed and the space was used as berthing for technicians and as a sonar lab. List of Gato-class submarines and their dispositions. However, they were completed by Manitowoc as Gatos, due to an unavoidable delay in Electric Boat's development of Balao-class drawings. I made the decision some time ago to fabricate all of the mounting plates from Aluminium. After looking at the 4 choices they say can be build from this kit, I have decided to go another route and using my book from the Oxford Press on the USS Cod. 6 officers, 54 enlisted men[3] Armament: 10 21-inch (533 mm) torpedotubes 6 forward, 4 aft 24 torpedoes[4] 1 3-inch (76 mm) / 50 caliberdeck gun[4] Bofors 40 mmand Oerlikon 20 mmcannon The United States Navy Gato-class submarineswere launched 1941-43 and were the first mass-production US submarineclass of World War II. [35] The conning tower fairwater of Flasher is preserved in Groton, Connecticut, in the mod 4A configuration, with two single 40mm Bofors mounts. [22] Frequent breakdowns and utter unreliability had destroyed these engines' reputation with the Navy and they were all removed at the first opportunity and replaced by General Motors Cleveland ; Operational experience with earlier boats led the naval architects and engineers at the Navy's Bureau of Construction and Repair to believe that they had been unduly conservative in their estimates of hull strength. The electronics and the engine functioned better in the dry, cool air. The Gato class of submarines was built for the United States Navy and launched in 1941-1943; they were the first mass-production U.S. submarine class of World War II. Japan received one (Mingo), Brazil two (Muskallunge & Paddle), Greece two (Lapon & Jack), and Turkey two (Guitarro & Hammerhead). [19][20], Like the previous Tambor/Gar classes, the Gato class could substitute mines in place of torpedoes. A streamlined Guppy style sail was installed, a large sonar array was wrapped around the bow (losing two torpedo tubes in the process), the boats were extensively silenced, and they received a snorkel. "Snorkel added" was similar to fleet snorkel, but only the after part of the sail was streamlined. Mod 4 Same as the Mod 3 but with the height of the bridge itself lowered in a last attempt to lessen the silhouette. Without changing the construction or thickness of the pressure hull steel, they decided that the Gato-class boats would be fully capable of routinely operating at 300 feet, a 50-foot increase in test depth over the preceding classes. Manitowoc's first Balao-class boat was USS Hardhead. Measuring 307 feet by 27 feet by 14 feet, Gato-class submarines had a typical displacement . Gato-class submarine model.jpg. The government-owned shipyards (Portsmouth Naval Shipyard and Mare Island Naval Shipyard) began to make the transition to the new Balao design in the summer of 1942. [45] The slow and less capable diesel SSKs were decommissioned or reassigned to other roles in 1959, and all except Croaker and Cavalla (eventually preserved as memorials) were scrapped in 1968 and 1969. 4 high-speed electric motors with reduction gears (Elliott Company, General Electric, or Allis-Chalmers)[1] Plan of Gato class submarine. Part of this is due to the American submarine being double the displacement of most Type IXs and nearly three times the displacement of the Type VIIs. Torpedo Loading Hatch located in Forward Torpedo Room; opens to. Features 1)Near 1:1 Scale Military Wiki is a FANDOM Lifestyle Community. but Engel plans to sell a new Gato kit which will be closer to the original very soon. Cars; Truck; Buses; Military; Motorcycle; Trains; AirCraft. Hawaii - NARA - 520836.tif. This model is designed and tested at 1/1800th scale, but up-scaling and down-scaling are possible. Named after the first vessel of this design, USS Gato, the Gato-class and its successors, the Balao and Tench classes, formed the core of the submarine service that was largely responsible for the destruction of the Japanese merchant marine and a large portion of the . Gato Class Cutaway $260.00 Finish: Deck Guns: Hull Number: Vessel Name: Challenge Coins: Availability: Usually ships in 1-2 weeks Product Description The fleet submarine of the United States Navy during World War 2. Electric Boat, due to the huge backlog of Gato-class construction, was not ready to make the transition to the new design until January 1943. The superstructure that sat atop the pressure hull provided the main walking deck when the boat was surfaced and was free flooding and full of water when the boat was submerged. Post-war, the Mk 49 mine replaced the Mk 12, while the larger Mk 27 mine was also carried which only allowed one mine replacing one torpedo. PT 1960-1971, AGSS 1Dec 1962, IXSS 30Jun 1971, struck 15Dec 1971. too many The modifications (or Mods) to the Gato-class conning tower fairwaters were fairly uniform in nature and they can be grouped together based on what was done when: Variations on the above mods included the 1A (shortened navigation bridge), 2A (plating removed from periscope shears), and the 3A and 4A (which moved the SJ radar mast aft of the periscopes).[24]. More like this Us Navy Submarines Us Navy Ships Battle Star United States Navy Power Boats Aircraft Carrier Battleship Us Army Infantry By 1940, a much better developed industrial base and experience gained from the Porpoise-, Salmon-, & Sargo-class boats resulted in the Tambor- & Gar-classes.
