John Lewis
John Robert Lewis (February 21, 1940 – July 17, 2020) was an American politician and civil rights activist who served in the United States House of Representatives for from 1987 until his death in 2020. He participated in the 1960 Nashville sit-ins, the Freedom Rides, was the chairman of the Student Nonviolent Coordinating Committee (SNCC) from 1963 to 1966, and was one of the " Big Six" leaders of groups who organized the 1963 March on Washington. Fulfilling many key roles in the civil rights movement and its actions to end legalized racial segregation in the United States, in 1965 Lewis led the first of three Selma to Montgomery marches across the Edmund Pettus Bridge where, in an incident which became known as Bloody Sunday, state troopers and police attacked Lewis and the other marchers. A member of the Democratic Party, Lewis was first elected to the U.S. House of Representatives in 1986 and served 17 terms. The district he represented included most of Atlanta. Due to hi ...

Civil Rights Movement
The civil rights movement was a nonviolent social and political movement and campaign from 1954 to 1968 in the United States to abolish legalized institutional Racial segregation in the United States, racial segregation, Racial discrimination in the United States, discrimination, and disenfranchisement in the United States, disenfranchisement throughout the United States. The movement had its origins in the Reconstruction era during the late 19th century, although it made its largest legislative gains in the 1960s after years of direct actions and grassroots protests. The social movement's major nonviolent resistance and civil disobedience campaigns eventually secured new protections in federal law for the civil rights of all Americans. After the American Civil War and the subsequent Abolitionism in the United States, abolition of slavery in the 1860s, the Reconstruction Amendments to the United States Constitution granted emancipation and constitutional rights of citizenship ...

Board Of Inspection And Survey
The Board of Inspection and Survey (INSURV) is a United States Navy organization whose purpose is to inspect and assess the material condition of U.S. Navy vessels. The Board is currently headquartered at Naval Amphibious Base Little Creek, Virginia. INSURV teams The Board performs its tasks by sending out teams at intervals not to exceed 60 months per Naval Ship. These teams evaluate a ship's readiness to conduct combat operations at sea, through an extensive system of checks on installed equipment. New construction When a ship has been constructed by a shipyard and turned over to the U.S. Navy, an INSURV team must certify the vessel prior to declaring it operational. History The ''Board of Inspection and Survey'' was established by Congress to ensure that the ships of the United States Navy are properly equipped for prompt, reliable, sustained mission readiness at sea. Originally established in 1868 under Admiral David Farragut, the board was reconstituted in 1877 with Admi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Christening
Baptism (from grc-x-koine, βάπτισμα, váptisma) is a form of ritual purification—a characteristic of many religions throughout time and geography. In Christianity, it is a Christian sacrament of initiation and adoption, almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or by immersing in water either partially or completely, traditionally three times, once for each person of the Trinity. The synoptic gospels recount that John the Baptist baptised Jesus. Baptism is considered a sacrament in most churches, and as an ordinance in others. Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. Baptism is also called christening, although some reserve the word "christening" for the baptism of infants. In certain Christian denominations, such as the Lutheran Churches, baptism ...

USNS John Lewis On The Day It Was Christened At General Dynamics NASSCO San Diego
United States Naval Ship (USNS) is the prefix designation given to non- commissioned ships that are property of the United States Navy (USN). Definition United States Naval Ships are unarmed auxiliary support vessels owned by the U.S. Navy and operated in non-commissioned service by Military Sealift Command with a civilian crew. Some ships include a small military complement to carry out communication and special mission functions, or for force protection. In comparison, U.S. Navy ships commissioned into service have the designation " USS" and are armed, crewed by U.S. Navy personnel, and held in property by the United States Government. Additionally, the United States Naval Ships hull classification symbol begins with "T-" to denote its civilian crew. The USNS prefix can be assigned only while the ship is owned by the U.S. Navy. If, after being taken out of service, the ship is transferred to the Maritime Administration the prefix reverts to a civilian ship prefix such ...

SeaRAM
The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican, UAE, and U.S. Navies. It was originally intended and used primarily as a point-defense weapon against anti-ship missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. The rolling interferometer permits the antennas to look at all planes of incoming energy. In addition, because the missile rolls, only one pair of steering canards is required. , it is the only U.S. Navy missile to operate in this manner. The Rolling Airframe Missiles, together with the Mk 49 Guided Missile Launching System (GMLS) and support equipment, make up the RAM Mk 31 Guided Missile Weapon System (GMWS). The Mk-144 Guided Miss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close-in Weapon System
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Example ...

AN/SLQ-25 Nixie
The AN/SLQ-25 Nixie and its variants are towed torpedo decoys used on US and allied warships. It consists of a towed decoy device (TB-14A) and a shipboard signal generator. The decoy emits signals to draw a torpedo away from its intended target. The Nixie attempts to defeat a torpedo's passive sonar by emitting simulated ship noise, such as propeller and engine noise, which is more attractive than the ship to the torpedo's sensors. The AN/SLQ-25A Nixie is a clean-sheet design when compared to the AN/SLQ-25 Nixie. Apart from a few minor mechanical components, they share no common parts. The AN/SLQ-25A utilises a fiber optic tow cable (FOTC) and a 10-horsepower RL-272C double drum winch. Several engineering changes resulted in COTS equipment being utilised extensively in the system. A diagnostic program can be initiated locally or from the remote control station, and tests all electronic functions. The AN/SLQ-25B includes equipment of the AN/SLQ-25A and incorporates a towed ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Degaussing
Degaussing is the process of decreasing or eliminating a remnant magnetic field. It is named after the gauss, a unit of magnetism, which in turn was named after Carl Friedrich Gauss. Due to magnetic hysteresis, it is generally not possible to reduce a magnetic field completely to zero, so degaussing typically induces a very small "known" field referred to as bias. Degaussing was originally applied to reduce ships' magnetic signatures during World War II. Degaussing is also used to reduce magnetic fields in cathode ray tube monitors and to destroy data held on magnetic storage. Ships' hulls The term was first used by then-Commander Charles F. Goodeve, Royal Canadian Naval Volunteer Reserve, during World War II while trying to counter the German magnetic naval mines that were wreaking havoc on the British fleet. The mines detected the increase in the magnetic field when the steel in a ship concentrated the Earth's magnetic field over it. Admiralty scientists, including Goodeve, ...

Crew-served Weapon
A crew-served weapon is any weapon system that is issued to a crew of two or more individuals performing the same or separate tasks to run at maximum operational efficiency, as opposed to an individual-service weapon, which only requires one person to run at maximum operational efficiency. The weight and bulk of the system often also necessitates multiple personnel for transportation. Crew-served weapons operated by infantry include sniper rifles, anti-materiel rifles, machine guns, automatic grenade launchers, mortars, anti-tank guns, anti-aircraft guns, recoilless rifles, shoulder-launched missile weapons, and static anti-tank and anti-aircraft missiles. See also * Heavy weapons platoon * Personal weapon and Small arms for weapons used by individuals * List of crew-served weapons of the U.S. Armed Forces This list contains weapons that are classified as crew-served, as the term is used in the United States military.
