Andromeda-class Attack Cargo Ship
The ''Andromeda''-class attack cargo ships were a class of amphibious cargo ship built by Federal Shipbuilding & Drydock Co. in Kearny, New Jersey and Moore Dry Dock Co., in Oakland, California during World War II. Like all attack cargo ships, they were designed to carry combat loaded military cargo and landing craft, and to use the latter to land weapons, supplies, and troops on enemy shores during amphibious operations. All these ships were built on the same standard hull design, but there were some differences from ship to ship. The armament varied, as did that of the other ships of the day. During 1944–1945, the 5"/38 was recognized as the best gun for the dual role of antiaircraft and naval gunfire support, and the 40 mm was seen as the best antiaircraft gun. The older 20 mm and .50 caliber guns had been recognized to be of limited value, and were being phased out, though they appeared on some of these ships. The 20 mm's were later removed from all ...

Federal Shipbuilding And Drydock Company
The Federal Shipbuilding and Drydock Company was a United States shipyard, active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board. During World War II, it built ships as part of the U.S. Government's Emergency Shipbuilding program. Operated by a subsidiary of the U.S. Steel, United States Steel Corporation, the shipyard was located at Kearny Point where the mouth of the Hackensack River meets Newark Bay in the Port of New York and New Jersey. The shipyard site is now part of River Terminal, a massive distribution facility that is partially a Foreign trade zones of the United States, foreign trade zone. Federal built numerous destroyers, destroyer escorts and a handful of light cruisers as well as merchant ships during and between the wars. Around 570 vessels were contracted for construction by Federal SB&DD Company with about 100 not delivered fully completed due to the end of the World War II. Federal also had a yard at Port ...

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 ...

List Of Ship Classes Of World War II
The List of ship classes of World War II is an alphabetical list of all ship classes that served in World War II. Only actual classes are included as opposed to unique ships (which are still included if they were the only one of a class to be built, for example, was the first of the four planned Admiral-class battlecruisers, but the other three were cancelled.) The list of ships of World War II contains major military vessels of the war, arranged alphabetically and by type. The list includes armed vessels that served during the war and in the immediate aftermath, inclusive of localized ongoing combat operations, garrison surrenders, post-surrender occupation, colony re-occupation, troop and prisoner repatriation, to the end of 1945. For smaller vessels, see also List of World War II ships of less than 1000 tons. Some uncompleted Axis ships are included, out of historic interest. Ships are designated to the country under which they operated for the longest period of the World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of United States Navy Amphibious Warfare Ships
This is a list of United States Navy amphibious warfare ships. This type of ship has been in use with the US Navy since World War I. Ship status is indicated as either currently active (including ready reserve), inactive or precommissioning Ships in the inactive category include only ships in the inactive reserve, ships which have been disposed from US service have no listed status. Ships in the precommissioning category include ships under construction or on order. Capabilities overview There have been four generations of amphibious warfare ships, with each generation having more capability than the previous: * The first generation simply landed troops and equipment ashore with standard (i.e., non-specialized) boats and barges. These ships are not listed in this article since they were indistinguishable from the troopships and other surface combatants of their day. * The second generation was designed during World War II to land personnel and vehicles ashore, either dire ...

Maritime Commission
The United States Maritime Commission (MARCOM) was an independent executive agency of the U.S. federal government that was created by the Merchant Marine Act of 1936, which was passed by Congress on June 29, 1936, and was abolished on May 24, 1950. The commission replaced the United States Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet. As a symbol of the rebirth of the U.S. Merchant Marine and Merchant Shipbuilding under the Merchant Marine Act, the first vessel contracted for ...

Dictionary Of American Naval Fighting Ships
The ''Dictionary of American Naval Fighting Ships'' (''DANFS'') is the official reference work for the basic facts about ships used by the United States Navy. When the writing project was developed the parameters for this series were designed to cover only commissioned US Navy ships with assigned names. If the ship was not assigned a name it was not included in the histories written for the series. In addition to the ship entries, ''DANFS'' and the online links have been expanded to include appendices on small craft, histories of Confederate Navy ships, and various essays related to naval ships. Forewords and introductions Foreword and introduction passages for many editions were written by big names from naval command history from Arleigh Albert Burke to Elmo Russell Zumwalt, Jr. and others. Authors Publication data ''DANFS'' was published in print by the Naval Historical Center (NHC) as bound hardcover volumes, ordered by ship name, from Volume I (A–B) in 1959 ...

Naval Gunfire Support
Naval gunfire support (NGFS) (also known as shore bombardment) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term ''naval fires''. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare. Tactics NGFS is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire. When on the gun line, ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submarines due to a predictable and steady (non-evasive) cou ...

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 ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

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 ...

Combat Loading
Combat loading is a special type of unit loading of ships so that embarked forces will have immediately needed weapons, ammunition and supplies stowed in such a way that unloading of equipment will be concurrent with the force personnel and available for immediate combat during an amphibious landing. It gives primary consideration to the ease and sequence with which troops, equipment, and supplies can be unloaded ready for combat, rather than to the efficient use of cargo space as in convoy loading where forces and equipment would be joined in rear or secure areas. The art and science of combat loading were developed in World War II, and contributed greatly to the success of Allied amphibious campaigns. While combat loading usually took place in forward bases, the Western Task Force for the landings in North Africa was combat loaded at the Army's Hampton Roads Port of Embarkation which was called on again for the Sicily force. Joint exercises in 1941 resulted in a decision that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
