USS John F. Kennedy (CV-67)
USS ''John F. Kennedy'' (CV-67) (formerly CVA-67), the only ship of her class, is an aircraft carrier, formerly of the United States Navy. Considered a supercarrier, she is a variant of the , and the last conventionally powered carrier built for the Navy, as all carriers since have nuclear propulsion. The ship was named after John F. Kennedy, the 35th President of the United States. ''John F. Kennedy'' was originally designated a CVA, for fixed wing attack carrier, however the designation was changed to CV, for fleet carrier. After nearly 40 years of service, ''John F. Kennedy'' was officially decommissioned on 1 August 2007. She is berthed at the NAVSEA Inactive Ships On-site Maintenance facility in Philadelphia, formerly the Philadelphia Naval Shipyard, and, until late 2017, was available for donation as a museum and memorial to a qualified organization. In late 2017, the Navy revoked her "donation hold" status and designated her for dismantling. She has been succeeded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Station Mayport
Naval Station Mayport is a major United States Navy base in Jacksonville, Florida. It contains a protected harbor that can accommodate aircraft carrier-size vessels, ship's intermediate maintenance activity (SIMA) and a military airfield (Admiral David L. McDonald Field) with one asphalt paved runway (5/23) measuring . Base history The station was commissioned in December 1942. It was reclassified as a Naval Sea Frontier base in 1943. A new naval auxiliary air station (NAAS) was established in April 1944. The naval section Base and the NAAS supported the Atlantic Fleet during World War II. Both were closed after the war. In June 1948, Mayport was reestablished as a naval outlying landing field. The base area was increased to and the runway was extended in the mid 1950s. became the first capital ship to use the new aircraft carrier basin in October 1952. The Base was renamed back to a Naval Auxiliary Air Station in July 1955. The naval station was extended to accommodate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Marine Propulsion
Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built. Compared to oil- or coal-fuelled ships, nuclear propulsion offers the advantages of very long intervals of operation before refueling. All the fuel is contained within the nuclear reactor, so no cargo or supplies space is taken up by fuel, nor is space taken up by exhaust stacks or combustion air intakes. However, the low fuel cost is offset by high operating costs and investment in infrastructure, so nearly all nuclear-powered vessels are military. Power plants Basic operation of naval ship or submarine Most naval nuclear reactors are of the pressuriz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is t ...

Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work '' De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Institute Press
The United States Naval Institute (USNI) is a private non-profit military association that offers independent, nonpartisan forums for debate of national security issues. In addition to publishing magazines and books, the Naval Institute holds several annual conferences. The Naval Institute is based in Annapolis, Maryland. Established in 1873, the Naval Institute claimed "almost 50,000 members" in 2020, mostly active and retired personnel of the United States Navy, Marine Corps, and Coast Guard. The organization also has members in over 90 countries. The organization has no official or funding ties to the United States Naval Academy or the U.S. Navy, though it is based on the grounds of the Naval Academy through permission granted by a 1936 Act of Congress. History The U.S. Naval Institute was formed on October 9, 1873 by fifteen naval officers gathered at the U.S. Naval Academy's Department of Physics and Chemistry building in Annapolis to discuss, among other topics, the impl ...

Ship Characteristics Board
The Ship Characteristics Board was a unit of the United States Navy. The purpose of the Ship Characteristics Board was to coordinate the creation of 'ship characteristics' that are essential to the design of naval combatants and auxiliaries. Coordination was required because the operators and the designers of ships had different interests, perceptions, and concepts: as summarized by the naval historian Norman Friedman, "How to achieve the best possible compromise among competing bureaus has been one of the great dilemmas of 20th-century U.S. naval administration." This list of SCB projects is a useful exposition of the U.S. Navy's shipbuilding priorities in the first half of the Cold War. History The Ship Characteristics Board was founded in 1945 under the Office of the Chief of Naval Operations / OpNav. It was created after the body previously responsible for coordinating ships characteristics, the General Board, had been seen as ineffective in a series of earlier Navy bureau ...

Museum Ship
A museum ship, also called a memorial ship, is a ship that has been preserved and converted into a museum open to the public for educational or memorial purposes. Some are also used for training and recruitment purposes, mostly for the small number of museum ships that are still operational and thus capable of regular movement. Several hundred museum ships are kept around the world, with around 175 of them organised in the Historic Naval Ships AssociationAbout The Historic Naval Ships Association (the international Historic Naval Ships Association website. Accessed 2008-06-06.) though many are not naval museum ships, from general merchant ships to tugboat, tugs and Lightvessel, lightships. Many, if not most, museum ships are also associated with a maritime museum. Significance Relatively few ships are ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia Naval Shipyard
The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries. Philadelphia's original navy yard, begun in 1776 on Front Street and Federal Street in what is now the Pennsport section of the city, was the first naval shipyard of the United States. It was replaced by a new, much larger yard developed around facilities begun in 1871 on League Island, at the confluence of the Delaware and Schuylkill rivers. The Navy Yard expansion stimulated the development over time of residential and businesses in South Philadelphia, where many shipyard workers lived. During World War II, some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort. The United States Navy ended most of its activities there in the 1990s, closing its base after recommendations by the Base Realignment and Closure commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the city of P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Inactive Ship Maintenance Facility
A Naval Inactive Ship Maintenance Facility (NISMF) is a facility owned by the United States Navy as a holding facility for decommissioned naval vessels, pending determination of their final fate. All ships in these facilities are inactive, but some are still on the Naval Vessel Register (NVR), while others have been struck from that Register. The ships that have been stricken from the NVR are disposed of by one of several means, including foreign military sales transfer, ship donation as a museum or memorial, domestic dismantling and recycling, artificial reefing, or use as a target vessel. Others are retention assets for possible future reactivation, which have been laid up for long-term preservation and are maintained with minimal maintenance (humidity control, corrosion control, flood/fire watch) should they need to be recalled to active duty. The Navy has been reducing the number of inactive ships, which numbered as many as 195 in 1997, but was down to 49 by the end of 201 ...

Ship Decommissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
