Crescent City Class Attack Transport
The ''Crescent City''-class attack transport was a class of U.S. Navy attack transports that saw service in World War II and the Korean War. There were four ships in the class: ''USS Crescent City'', ''USS Charles Carroll'', ''USS Monrovia'', and ''USS Calvert''. Like all attack transports, the purpose of the ''Crescent City'' ships was to transport troops and their equipment to foreign shores in order to execute amphibious invasions using an array of smaller assault boats integral to the attack transport itself. Also like all the attack transports, the class was armed with antiaircraft weaponry to protect itself and its cargo of troops from air attack in the battle zone. Class history The ''Crescent City'' class began as a class of Navy transport ships (classification AP). Like many other transports, they were redesignated attack transports (APA) on 1 February 1943, the date on which the Navy formalized its separate classification of transport vessels into ordinary tr ...

Bethlehem Steel
The Bethlehem Steel Corporation was an American steelmaking company headquartered in Bethlehem, Pennsylvania. For most of the 20th century, it was one of the world's largest steel producing and shipbuilding companies. At the height of its success and productivity, the company was a symbol of American manufacturing leadership in the world, and its decline and ultimate liquidation in the late 20th century is similarly cited as an example of America's diminished manufacturing leadership. From its founding in 1857 through its 2003 dissolution, Bethlehem Steel's headquarters and primary steel mill manufacturing facilities were based in Bethlehem, Pennsylvania in the Lehigh Valley region of the United States. The company's steel was used in the construction of many of America's largest and most famed structures. Among major buildings, Bethlehem produced steel for 28 Liberty Street, the Chrysler Building, the Empire State Building, Madison Square Garden, Rockefeller Center, and the Wa ...

USS Crescent City (APA-21)
USS ''Crescent City'' (AP-40/APA-21) was the lead ship of the ''Crescent City''-class attack transports that served with the US Navy during World War II. The ship was built as the cargo and passenger liner ''Delorleans'' for the Mississippi Shipping Company's Delta Line. After brief commercial operation the ship was among 28 vessels requisitioned in June 1941 for the Navy and the Army. The Navy renamed the ship ''Crescent City'', a popular nickname for New Orleans, Louisiana, upon commissioning 10 October 1941. The ship was decommissioned and laid up in 1948 before being loaned to the California Maritime Academy to serve as a training ship 1971–1995 and then transferred to a foundation in a failed art colony project. The ship left California for Texas scrapping in 2012. Construction Originally named the SS ''Delorleans'', the ship was contracted on 16 December 1938 by Maritime Commission as a Type C3 ship hull No. 49. The keel was laid 8 May 1939, by the Bethlehem Stee ... [...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] |
Mediterranean, Middle East And African Theatres Of World War II
The Mediterranean and Middle East Theatre was a major theatre of operations during the Second World War. The vast size of the Mediterranean and Middle East theatre saw interconnected naval, land, and air campaigns fought for control of the Mediterranean, North Africa, the Horn of Africa, the Middle East and Southern Europe. The fighting in this theatre lasted from 10 June 1940, when Italy entered the war on the side of Germany, until 2 May 1945 when all Axis forces in Italy surrendered. However, fighting would continue in Greece – where British troops had been dispatched to aid the Greek government – during the early stages of the Greek Civil War. The British referred to this theatre as the Mediterranean and Middle East Theatre (so called due to the location of the fighting and the name of Middle East Command), the Americans called it the Mediterranean Theater of War and the German informal official history of the fighting is The Mediterranean, South-East Europe, and North A ...

3"/50 Caliber Gun
The 3"/50 caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through to 1994 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3"/50 caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Merchant Ships. Low-angle 3"/50 caliber guns (Marks 3, 5, 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Ship
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ship ...

Bethlehem Sparrows Point Shipyard
Maryland Steel, in Sparrows Point, Maryland, US, was founded in 1887. It was acquired by Bethlehem Shipbuilding Corporation in 1916 and renamed as the Bethlehem Sparrows Point Shipyard. The shipyard was sold in 1997 to Baltimore Marine Industries Inc.. In 2012, it was owned by Barletta Industries, which had converted it to the Sparrows Point Shipyard and Industrial Complex. As of 2021, it is owned by Sparrows Point Terminal, LLC and has been renamed Tradepoint Atlantic. History Maryland Steel built tugs, coastal passengers, dredges, cargo ships and a few destroyers. Following the purchase by Bethlehem, it serviced and repaired ships and manufactured industrial products. One famous vessel built in this early period was the , launched as ''Shawmut'', which, in 1914, was the first ship to transit the Panama Canal. Facilities at the yard included a graving dock, a floating drydock and two full-service outfitting piers which together provided nearly 3,000 feet of berthing space. Wor ...

Type C3 Ship
Type C3-class ships were the third type of cargo ship designed by the United States Maritime Commission (MARCOM) in the late 1930s. As it had done with the Type C1 ships and Type C2 ships, MARCOM circulated preliminary plans for comment. The design presented was not specific to any service or trade route, but was a general purpose ship that could be modified for specific uses. A total of 162 C3 ships were built from 1939 to 1946. The C3 was larger and faster than the C1 and C2 contemporaries, measuring from stem to stern (vs. for the C2), and designed to make (vs. for the C2). Like the C2, it had five cargo holds. A total of 465 of these ships were built between 1940 and 1947. A total of 75 ships were built with C3 hulls and engines, but not built as cargo ships. During World War II, many C3 ships were converted to naval uses, particularly as s, and as and s, ''Klondike''-class destroyer tenders, submarine tenders, and seaplane tenders. Ships in type *C3 DWT 12,595 as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antiaircraft
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraf ...

Landing Craft
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow. This made them difficult to control and very uncomfortable in rough seas. The control point (too rudimentary to call a bridge on LCA and similar craft) was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title. History In the days of sail, the ship's boats were us ...

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named ''Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, scale an ...
