USS West Virginia (BB-48)
USS ''West Virginia'' (BB-48) was the fourth dreadnought battleship of the , though because was cancelled, she was the third and final member of the class to be completed. The ''Colorado'' class proved to be the culmination of the standard-type battleship series built for the United States Navy in the 1910s and 1920s; the ships were essentially repeats of the earlier design, but with a significantly more powerful main battery of eight guns in twin-gun turrets. ''West Virginia'' was built between her keel laying in 1920 and her commissioning into the Navy in 1923. The ship spent the 1920s and 1930s conducting routine training exercises, including the typically-annual Fleet Problems, which provided invaluable experience for the coming war in the Pacific. ''West Virginia'' was moored on Battleship Row on the morning of 7 December 1941 when Japan attacked Pearl Harbor, bringing the United States into World War II. Badly damaged by torpedoes, the ship sank in the shallow wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

CXAM Radar
The CXAM radar system was the first production radar system deployed on United States Navy ships, operating in the mid-high VHF frequency band of 200 MHz. It followed several earlier prototype systems, such as the NRL radar installed in April 1937 on the destroyer ; its successor, the XAF, installed in December 1938 on the battleship ; and the first RCA-designed system, the CXZ, installed in December 1938 or January 1939 on the battleship . Based on testing in January 1939, where the XAF was more reliable, the US Navy ordered RCA to build six XAF-based units for deployment and then shortly thereafter ordered 14 more. The first six units RCA produced (delivered in 1940) were denoted "CXAM" and were a fusion of XAF and CXZ technologies. These were installed on the battleship , the aircraft carrier (in September 1940), and the heavy cruisers , , , and . The next 14 units RCA produced (also delivered in 1940) were denoted "CXAM-1" and were slight improvements over the CXAM desi ...

Battleship Row
Battleship Row was the grouping of eight U.S. battleships in port at Pearl Harbor, Hawaii, when the Japanese attacked on 7 December 1941. These ships bore the brunt of the Japanese assault. They were moored next to Ford Island when the attack commenced. The ships were , , , , , , , and . A repair ship (former coal ship), , was also present, moored next to ''Arizona''. Creation When the United States Navy decided in 1919 to establish a major naval base in Pearl Harbor, the southeastern side of Ford Island was ceded from control of the Army Air Service at the behest of Secretary of War Newton D. Baker. Due to its location in the center of the harbor, where the water was deepest and the potential for maneuvering greater than along the shores, this coast of Ford Island became the de facto mooring location for the Pacific Fleet's battleships and took on the nickname "Battleship Row". Attack and aftermath ''Arizona'', ''California'', ''Oklahoma'', and ''West Virginia'' were sunk d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleet Problem
The Fleet Problems are a series of naval exercises of the United States Navy conducted in the interwar period, and later resurrected by Pacific Fleet around 2014. The first twenty-one Fleet Problems — labeled with roman numerals as Fleet Problem I through Fleet Problem XXI — were conducted between 1923 and 1940. They were usually once-a-year exercises in which U.S. naval forces would engage in mock battles. One or more of the forces would play the part of a European or Asian navy. They were the culmination of the Navy's annual training maneuvers. Fleet Problem XXII, scheduled for 1941, was canceled because of the rising tensions with Japan that led to the US' entry into World War II. Following the outbreak of war, Fleet Problems underwent a prolonged hiatus, with other names being used to describe large American naval exercises. However, the term was revived in the 21st century under Admiral Scott H. Swift, with Fleet Problem XXIII through XXVIII taking place in the Pacific ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a gun or group of guns, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles as a vessel's principal offensive weapon, deployed both on surface ships and submarines. A main battery features common parts, ammunition, and fire control across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and below the water their principal group became a ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the United States Navy is the third largest of the United States military service branches in terms of personnel. It has 290 deployable combat vessels and more than 2,623 operational aircraft . The United States Navy traces its origins to the Continental Navy, which was established during the American Revo ...

Standard-type Battleship
The Standard-type battleship was a series of twelve battleships across five classes ordered for the United States Navy between 1911 and 1916 and commissioned between 1916 and 1923. These were considered super-dreadnoughts, with the ships of the final two classes incorporating many lessons from the Battle of Jutland. Each vessel was produced with a series of progressive innovations, which contributed to the pre–World War I arms race. The twelve vessels constituted the US Navy's main battle line in the interwar period, while many of the ten earlier dreadnoughts were scrapped or relegated to secondary duties. Restrictions under the 1922 Washington Naval Treaty limited total numbers and size of battleships and had required some under construction to be cancelled, so it was not until the onset of World War II that new battleships were constructed. On December 7, 1941, eight were at Pearl Harbor, one at Bremerton, Washington, and three were assigned to the Atlantic Fleet. Doctri ...

Dreadnought Battleship
The dreadnought (alternatively spelled dreadnaught) was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's , had such an impact when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the Causes of World War I#Arms race, naval arms race between the Anglo–German naval arms race, United Kingdom and Germany. Dreadnought races sprang up around the world, including South American dreadnought race, in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour and propulsion throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
