USS Hunley (AS-31)
USS ''Hunley'' (AS-31) was a submarine tender of the United States Navy launched on 28 September 1961 and commissioned 16 June 1962. The ''Hunley'' was designed to tend most of the long-term requirements of the Polaris Class of submarines. The ship achieved several records and milestones in its service. The ''Hunley'' was decommissioned from the regular navy, in 1995 transferred to the US Maritime Commission, and in 2007 sold as scrap to a metal recycling company in Louisiana. In September 2008, during Hurricane Gustav, the decommissioned ship broke free of its moorings in the New Orleans Inner Harbor, but caused little or no damage while adrift. Design and construction ''Hunley'' had the distinction of being the first ship designed and built from the keel up to service and maintain the U.S. Navy's nuclear-powered Ballistic Missile Submarine Fleet. She had complete facilities for servicing the complex Polaris Weapons Systems and for accomplishing any submarine repair other t ...

Horace Lawson Hunley
Horace Lawson Hunley (December 29, 1823 – October 15, 1863) was a Confederate States of America, Confederate Marine engineering, marine engineer during the American Civil War. He developed early hand-powered submarines, the most famous of which was posthumously named for him, H. L. Hunley (submarine), CSS ''H. L. Hunley''. Biography Horace Lawson Hunley was born in Sumner County, Tennessee to Louisa Harden Lawson and John Hunley. After relocating to New Orleans, Hunley studied law at the Tulane University, University of Louisiana and was admitted to the bar in 1849. He served in the Louisiana State Legislature and practiced law in New Orleans. In response to the Union blockade of southern ports the Confederate government offered bounties of up to $50,000 to anyone who sank a Union warship. In the summer of 1861, the Reverend Franklin Smith advocated southern businessmen pursue submarine warfare, in writings to Southern newspapers. At this time Hunley joined engineer James R. ...

Missile Crane
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still r ...

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The surprise attack by the Imperial Japanese Navy on December 7, 1941, led the United States to declare war on the Empire of Japan, making the attack on Pearl Harbor the immediate cause of the United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning, “Waters of Pearl”) or ''Puuloa'' (meaning, “long hill”) by the Hawaiians. Puuloa was r ...

Induction Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel ...

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] |

Submarine Hull
A submarine hull has two major components, the ''light hull'' and the ''pressure hull''. The light hull (''casing'' in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that maintains structural integrity with the difference between outside and inside pressure at depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced. History The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Spanish inventor Narcís Monturiol in 1859. However, whe ... [...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] |
