USS O'Bannon (DD-177)
USS ''O'Bannon'' (DD-177) was a built for the United States Navy during World War I. Description The ''Wickes'' class was an improved and faster version of the preceding . Two different designs were prepared to the same specification that mainly differed in the turbines and boilers used. The ships built to the Bethlehem Steel design, built in the Fore River and Union Iron Works shipyards, mostly used Yarrow boilers that deteriorated badly during service and were mostly scrapped during the 1930s.Gardiner & Gray, p. 124 The ships displaced at standard load and at deep load. They had an overall length of , a beam of and a draught of . They had a crew of 6 officers and 108 enlisted men. Performance differed radically between the ships of the class, often due to poor workmanship. The ''Wickes'' class was powered by two steam turbines, each driving one propeller shaft, using steam provided by four water-tube boilers. The turbines were designed to produce a total of intended t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS O'Bannon (DD-177) Underway, Circa In 1920
Three ships of the United States Navy have been named USS ''O’Bannon'', after the early Marine Corps hero Presley O'Bannon Presley O'Bannon (1776 – September 12, 1850) was a first lieutenant in the United States Marine Corps, famous for his exploits in the First Barbary War (1801-1805).

Yarrow Boiler
Yarrow boilers are an important class of high-pressure water-tube boilers. They were developed by Yarrow & Co. (London), Shipbuilders and Engineers and were widely used on ships, particularly warships. The Yarrow boiler design is characteristic of the three-drum boiler: two banks of straight water-tubes are arranged in a triangular row with a single furnace between them. A single steam drum is mounted at the top between them, with smaller water drums at the base of each bank. Circulation, both upwards and downwards, occurs within this same tube bank. The Yarrow's distinctive features were the use of straight tubes and also circulation in both directions taking place within the tube bank, rather than using external downcomers. Early watertube boilers Early use of the water-tube boiler within the Royal Navy was controversial at times, giving rise to the '' 'Battle of the Boilers' '' around 1900. These first boilers, such as the Belleville and Niclausse, were large-tube desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Vessel Register
The ''Naval Vessel Register'' (NVR) is the official inventory of ships and service craft in custody of or titled by the United States Navy. It contains information on ships and service craft that make up the official inventory of the Navy from the time a vessel is authorized through its life cycle and disposal. It also includes ships that have been removed from the register (often termed ''stricken'' or ''struck''), but not disposed of by sale, transfer to another government, or other means. Ships and service craft disposed of prior to 1987 are currently not included, but are gradually being added along with other updates. History The NVR traces its origin back to the 1880s, having evolved from several previous publications. In 1911, the Bureau of Construction and Repair published ''Ships Data US Naval Vessels'', which subsequently became the ''Ships Data Book'' in 1952 under the Bureau of Ships. The Bureau of Ordnance's ''Vessel Register'', first published in 1942 and retitl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest prot ...

Anti-aircraft Gun
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 airc ...

Artillery Battery
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. Land usage Historically the term "battery" referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannon in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used as ...

Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil, marine fuel oil (MFO), bunker fuel, furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat (heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecules, such as ...

Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull ( keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
