The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames . All the early boats were built with this mod and it lasted until about mid-1942. Torpedo Loading Hatch located in Forward Torpedo Room; opens to. Like most other U.S. Navy submarines of the period, the Gato-class were given the names of marine creatures. 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. Floating Drydock has the best Gato plans. Enlisted men repair and check instruments aboard a submarine just returned to Pearl Harbor. Enough of the Balao and Tench boats, with their greater diving depth, remained that the Gatos were superfluous for front-line missions. 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. While most of these boats were of the more capable Balao- and Tench-classes, some Gatos went overseas as well. The lowering of the bridge exposed three I-beams on either side of the periscope shears. 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. At the end of World War II, the USN found itself in an awkward position. 16-278A V-type diesels. The outer hull merged with the pressure hull at both ends in the area of the torpedo room bulkheads, hence the "partial" double hull. The Gatos, and their successors, the Balao and Tench class subs, formed the vast majority of the U. S. Submarines in the second world war. [19] Manitowoc was a designated follow-on yard to Electric Boat; they used construction blueprints and plans supplied by Electric Boat and used many of the same suppliers. Although a point of concern, the turning radius was still acceptable. She was commissioned on 1 November 1941 and was the only Gato-class boat in commission when the war started. Grouper was the test boat for the concept, having her sonar array at the forward end of the sail instead of the better position at the bow. [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. They were to scout out ahead of the fleet and report on the enemy fleet's composition, speed, and course, then they were to attack and whittle down the enemy in preparation for the main fleet action, a titanic gun battle between battleships and cruisers. They have copies of the actual builders prints, including hull stations. Do you want your video to appear on our website? 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. [46], With the retirement of the Regulus missile system in 1965, Tunny was converted into a troop transport in 1966. All in all they conducted 27 war patrols but could not claim any verified sinkings. The 56 remaining Gato-class submarines, designed to fight an enemy that no longer existed, were largely obsolete despite the fact they were only two to four years old. She received additional "saddle" tanks wrapped around her outer hull to carry these fuels and a streamlined sail. 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. Box has lots of shelf rash but the kit is pristine. This is a kit by Revel in 1/72 scale. This page was last edited on 26 October 2022, at 02:26. [24] 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). They were used strictly as pierside trainers. She could carry two of the missiles in a cylindrical hangar on the aft deck. The advent of the Kamikaze demonstrated the need for a long range radar umbrella around the fleet. [17] Due to their large construction capacity, more than half (41) of the class was built at Electric Boat facilities; three new slipways were added to the north yard and four slipways were added to the south yard to accommodate their production. USS Gato off Mare Island Navy Yard, on 29 November 1944. However, in the summer of 1942, six brand 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. Grouper was converted under project SCB 58 as the test boat for the concept, having her sonar array at the forward end of the sail instead of the better position at the bow. Mod 3 Same as mod 2, but with the covered navigation bridge on the forward part of the fairwater cut away and the plating around the periscope shears removed. submit wallpaper HD wallpaper: class, gato, submarines, uss . [31] A total of 77 Gatos were built at four different locations (Electric Boat, Manitowoc, Portsmouth, and Mare Island). She received additional "saddle" tanks wrapped around her outer hull to carry these fuels and a streamlined sail. 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. [29], The large numbers of relatively modern, but surplus U.S. fleet submarines proved to be popular in sales, loans, or leases to allied foreign navies. They met the U.S. Navy's requirements for long offensive cruises in the . In this configuration the. 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. Mod 3 Same as Mod 2 but with the covered navigation bridge on the forward part of the fairwater cut away and the plating around the periscope shears removed. Uss Growler Submariner Nautilus Us Navy Seas World War Ii Naval Ww2 Imperial More information . In 1957 she converted back to the oiler/tanker role and carried the designation AOSS. The Gato-class boats were considered to be "Fleet Submarines". 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. The Balao-class was a successful design of United States Navy submarine used during World War II, and with 122 units built, the largest class of submarines in the United States Navy. 5,400shp (4,000kW) surfaced[1]. Although a point of concern, turning radius was still good enough to be acceptable. The Gato class were a class of submarines 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. High humidity generated by tropical waters will quickly condense and begin dripping into equipment, eventually causing electrical shorts and fires. The other Gato-class boats received either the Fairbanks-Morse 38D8 1/8 nine cylinder opposed piston engine or the GM-Winton 16-248 V-type as original installations. Whitman, Edward C.

Gato-class submarine model.jpg. ARTIST: James Griffiths (Illinois, born 1947) NAME: Sail Ship - Port Jackson (titled on verso) YEAR: 1977 MEDIUM: watercolor on paper CONDITION: Very good. two propellors[1] Molded in gray with retro box art. [7], 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. The Gato class of submarines was built for the United States Navy and launched in 19411943; they were the first mass-production U.S. submarine class of World War II. The only significant difference was five feet in length added to the engine room section to allow the addition of a watertight bulkhead, dividing the one large engine room in two, with two diesel generator sets in each room. 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). Hawaii - NARA - 520836.tif. 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]. 17 gun (although some boats received older Mk. Tunny was converted in 1953 to house and fire this large surface-launched missile and was designated SSG. Finally, the USN had hit the right combination of factors and now had the long-desired fleet submarine. List of Gato -class submarines List of Gato -class submarines and their dispositions. The electronics and the engine functioned better in the dry, cool air. 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.. Named after the lead ship of the class, USS Gato, the Gatos and . 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. Below are typical booklet of general plans (ship drawings). The Gatos were subjected to numerous exterior configuration changes during their careers, with most of these changes centered on the conning tower fairwater. An improvement on the earlier Gato-class, the boats had slight internal differences. In addition, the government purchased an old foundry downstream from the main yard, constructed 10 slipways, and turned the yard over to Electric Boat. Scale. Gato's name comes from a species of small catshark. By midwar, these measures combined with improved crew training got dive times down to 3035 seconds, very fast for such a large boat and acceptable to the boat's crew. The Gatos were subjected to numerous exterior configuration changes during their careers, with most of these changes centered on the conning tower fairwater. Gato -class boats sank three Japanese submarines: I-29, I-168 and I-351; while only losing one in exchange, USS Corvina to I-176. Unfortunately, the HOR company ran into severe design and manufacturing problems and these engines proved to be operational and maintenance nightmares. The Gato class submarine served the United States Navy well during World War II. Mod 4 Same as the Mod 3 but with the height of the bridge itself lowered in a last attempt to lessen the silhouette. Secondly, the desire to incorporate new masts for surface- and air-search radars drove changes to the fairwater and periscope shears. [42], Eventually more advanced sonars were installed on the new nuclear boats: Tullibee, commissioned in 1960, introduced the bow-mounted sonar sphere. After a few tests the concept was dropped in 1951 as impractical and Guavina served in the test role for a few years. They were to scout out ahead of the fleet and report on the enemy fleet's composition, speed, and course, then they were to attack and whittle down the enemy in preparation for the main fleet action, a titanic gun battle between cruisers and battleships. To operate effectively in this role, a submarine had to have high surface speed, long range and endurance, and heavy armament. 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. Class overview; Name: Gato class: Builders: Electric Boat Company; Portsmouth Naval Shipyard [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. 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. A new submarine class was proposed and approved by the government in 1939. Escape trunk located in the Forward Torpedo Room: Upper hatch to outside the ship, side door to outside companionway, lower hatch into the ship. [8] Limitations in submarine design and construction in the 1920s and 1930s made this combination of qualities very difficult to achieve. The outer hull merged with the pressure hull at both ends in the area of the torpedo room bulkheads, thus the "partial" double hull. The inner pressure-resisting hull was wrapped by an outer hydrodynamic hull. 1/240 Scale. Spread the love Photo: Depositphotos The US Navy announced the interception in the Gulf of Oman of a fishing vessel that was transporting more than 2,000 Kalashnikov assault rifles from Iran to Yemen. This model is designed and tested at 1/1800th scale, but up-scaling and down-scaling are possible. 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. Mod 1 This is the original configuration with the covered navigation bridge, the high bulwark around the aft "cigarette" deck, and with the periscope shears plated over. Deck guns varied during the war. FOUND A BOX so now . Have you a channel youtube and want to bring your Video to quality visitors? [2] But success had a price: 20 of the 52 US submarines lost in that war were of this class, plus Halibut, a damaged boat that returned to the US but was considered a constructive total loss and not repaired. They were also armed with one 3 inch deck gun and a variety of smaller anti-aircraft weapons. 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. [9] The U.S. Navy experimented constantly with this concept in the post-World War I years, producing a series of submarines with less than stellar qualities and reliability, the AA-1 class (also known as the T class) and the V-boats, of which V-1 through V-3 were an unsuccessful attempt to produce a fleet submarine. 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 including the removal of the two forward diesel engines, and they received a snorkel. The Navy had been tinkering with this engine off and on since 1937 because its unique design promised nearly twice the horsepower in a package the same size as other diesel engine types. Revell Gato Class Submarine Conversion. 77 total submarines were built between 1940 and 1944. Plan of Gato class submarine. By the end of 1941, 33 Gato keels had been laid. The US Gato-class submarines were the first US mass-produced submarines. Manitowoc's first Balao-class boat was Hardhead.[27][28].

The Navy had been tinkering with this engine off and on since 1937 because its unique design promised nearly twice the horsepower in a package the same size as other diesel engine types. Sufficient fuel bunkerage to provide the range necessary for 75-day patrols from Hawaii to Japan and back could only be obtained with a large boat, which will take longer to submerge than a smaller one. Unfortunately, it also was full of faults, the most dangerous being a tendency to run in a circular pattern and come back at the sub that fired it.
