Chourre-class Aircraft Repair Ship
The ''Chourre''-class aircraft repair ship was a class of repair ships that were operated by the United States Navy during World War II. Design ''Chourre''-class was the first ship class to be designated as aircraft repair ships in the Navy. The class consists of two ships converted from the EC2-S-C1, also known as Liberty ships. The ships were long overall ( Length between perpendiculars, between perpendiculars, with a beam of . She had a depth of and a draft of . She was assessed at , , . She was powered by a triple expansion steam engine, which had cylinders of , and diameter by stroke. The engine was built by the Babcock & Wilcox. It drove a single screw propeller, which could propel the ship at . They served well throughout the war without a ship being lost to enemy action. After the war, they were decommissioned but only ''Chourre'' was reactive to take part in the Korean War. Ships in the class References {{DEFAULTSORT:Chourre World War II auxiliary ...

Bethlehem Fairfield Shipyard
The Bethlehem-Fairfield Shipyard of Baltimore, Maryland, was a shipyard in the United States from 1941 until 1945. Located on the south shore of the Middle Branch of the Patapsco River which serves as the Helen Delich Bentley Port of Baltimore, Baltimore Harbor, it was owned by the Bethlehem Shipbuilding Company, created by the Bethlehem Steel Corporation of Bethlehem, Pennsylvania, which had operated a major waterfront steel mill outside Baltimore to the southeast at Sparrows Point, Maryland in rural Baltimore County since the 1880s. The yard is now the location to the west of several heavy industrial firms with a focus on petro-chemicals, a later Maryland Shipbuilding and Drydock Company, which endured into the 1990s, and the underground south entrance of the Baltimore Harbor Tunnel, built in 1956–1957, carrying Interstate 895 (Maryland), Interstate 895 and the Baltimore Harbor Tunnel Thruway through and under the city in the major East Coast of the United States, East Coast th ...

Aircraft Repair Ship
Aircraft repair ship is a naval auxiliary ship designed to provide maintenance support to aircraft. Aircraft repair ships provide similar services to seaplane tenders, that also cared for the crew. Aircraft repair ships had their own stores of spare parts, like a depot ship. Aircraft repair ships had repair personnel and equipment to repair failures or battle damage on aircraft. Aircraft repair ship also did regular aircraft maintenance.Lenton & Colledge, p.333 United States Navy During World War II there was a great demand for aircraft repair ships. The United States Navy aircraft repair ship were manned by repair units, called Carrier Aircraft Service Units. If needed a Carrier Aircraft Service Unit could be redesignated into a Combat Aircraft Service Unit, Scout Observation Service unit or Patrol Service units. These units could also be land-based or on an aircraft repair ship. Some cargo ships were converted into aircraft repair ships to aid in the repair needs of the Worl ...

World War II Auxiliary Ships Of The United States
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Reef
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing. Many reefs are built using objects that were built for other purposes, such as by sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Other artificial reefs are purpose-built (e.g. the reef balls) from PVC or concrete. Shipwrecks may become artificial reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach; the accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. History The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Webster (ARV-2)
USS ''Webster'' (ARV-2) was a Chourre class aircraft repair ship that saw service in the United States Navy during World War II. On 30 March 1944, prior to the beginning of work on her construction, ''Masbate'' (ARG-1) was renamed ''Webster'' and reclassified ARV-2. The ship's keel was laid down under a Maritime Commission contract (MCE hull 2666) on 1 July 1944 at Baltimore, MD, by the Bethlehem Fairfield Shipyard, Inc. Sponsored by Mrs. Walter W. Webster, the widow of the ship's namesake, the ship was launched on 5 August 1944 and commissioned at Baltimore on 17 March 1945. After fitting out, ''Webster'' departed Baltimore on 22 March 1945 and arrived at Norfolk Naval Base later that day. There, the aircraft repair ship loaded supplies and provisions into the second week of April, when she got underway for shakedown and training in Chesapeake Bay. After subsequent minor repairs and alterations at the Norfolk Navy Yard from 21 April to 8 May, ''Webster'' joined Convoy No. 50 ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple Expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them th ...
