USS Rock (SS-274)
USS ''Rock'' (SS/SSR/AGSS-274), a Gato class submarine, ''Gato''-class submarine, was a ship of the United States Navy named for the rockfish, a striped bass found in the Chesapeake Bay region and elsewhere along the United States East Coast. Construction and commissioning ''Rock'' was Keel-laying, laid down by the Manitowoc Shipbuilding Company at Manitowoc, Wisconsin, Manitowoc, Wisconsin, on 23 December 1942; Ceremonial ship launching, launched on 20 June 1943, sponsored by Mrs. B. O. Wells, and Ship commissioning, commissioned on 26 October 1943. Service history World War II After a month of intensive training in Lake Michigan, ''Rock'' passed through the Chicago Sanitary and Ship Canal (at the time known as the Chicago Drainage Canal) to Lockport, Illinois, Lockport, Ill. There she entered a floating drydock for her voyage down the Mississippi River. She arrived in New Orleans, Louisiana, New Orleans on 29 November 1943, and got underway 6 days later for Panama, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manitowoc Shipbuilding Company
Manitowoc Shipbuilding Company, located in Manitowoc, Wisconsin, was a major shipbuilder for the Great Lakes. It was founded in 1902, with the purchase of the "Burger & Burger Shipyard," a predecessor to The Burger Boat Company, and made mainly steel ferry, ferries and ore haulers. During World War II, it built submarines, Landing Craft Tank, tank landing craft (LCTs), and self-propelled fuel barges called "YOs". Employment peaked during the military years at 7000. The shipyard closed in 1968, when The Manitowoc Company, Manitowoc Company bought Bay Shipbuilding Company and moved their shipbuilding operation to Sturgeon Bay, Wisconsin, Sturgeon Bay. Submarine building program Shipyard President Charles C. West contacted the Bureau of Construction and Repair in 1939 to propose building destroyers at Manitowoc and transporting them through the Chicago River, Chicago Sanitary and Ship Canal, Illinois River, and Mississippi River in a floating drydock towed by the tugboat ''Minnesot ...

Lake Michigan
Lake Michigan ( ) is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume () and depth () after Lake Superior and the third-largest by surface area (), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the wide and deep Straits of Mackinac, giving it the same surface elevation as its eastern counterpart; hydrologically, the two bodies are Lake Michigan–Huron, a single lake that is, by area, the largest freshwater lake in the world. Lake Michigan is the only Great Lake located fully in the United States; the other four are shared between the U.S. and Canada. It is the world's List of lakes by area, largest lake, by area, located fully in one country, and is shared, from west to east, by the U.S. states of Wisconsin, Illinois, Indiana, and Michigan. Ports along its shores include Chicago, Illinois, Gary, Indiana, Gary, Indiana, Milwaukee and Green Bay, Wisconsin, Green Bay, Wis ...

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in Armored car (military), armoured vehicles. More complex periscopes using Prism (optics), prisms or advanced Optical fiber, fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unatte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...

Japanese Destroyer Asashimo
was a of the Imperial Japanese Navy. ''Asashimo'' sank the submarine USS ''Trout'' on 29 February 1944, survived the battles of Leyte Gulf and Ormoc Bay, and was finally was among the several ships sunk during Operation Ten-Go by attacking US aircraft on 7 April 1945. Service career and fate On 29 February 1944, while escorting a large convoy en route to Truk, ''Asashimo'' detected the submarine making a night surface approach on the convoy. ''Rock'' fired a spread of four torpedoes from her stern tubes at the closing ''Asashimo'' without scoring a hit. Illuminated by the destroyer's searchlight, and under fire from the ship's 5-inch (130 mm) guns, ''Rock'' dived. For four hours ''Asashimo'' continued depth charge attacks, without success. That night ''Rock'' surfaced and found that her periscopes were excessively damaged and that her bridge had been riddled with shrapnel. The damage necessitated a return to Pearl Harbor for repairs. Later that night, the busy ''Asashim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887.
