LX(R)-class Amphibious Warfare Ship
The LX(R) class (formerly LSD(X) class) is a class of amphibious warfare ships under development for the United States Navy, to be contracted from 2020, as a replacement for the current and dock landing ships. The LX(R) is expected to enter service by 2025 or 2026. It will complement existing ''Whidbey Island''-class and ''Harpers Ferry''-class ships in U.S. service, eventually replacing these ships by 2039. Development The LX(R) was previously referred to as the LSD(X). The designation was changed to LX(R) in 2012 to signal that the replacement for the existing and ships (LSD-41/49 class) would be an amphibious warfare ship that would meet the needs of the U.S. Navy and Marine Corps, regardless of whether that turned out to be a ship that might be designated as a dock landing ship (LSD). In 2013 and 2014 the Navy conducted a review of various design alternatives for the LX(R), including: adopting the existing design as-is, adopting a modified version of the ''San Antoni ...

Amphibious Warfare Ship
An amphibious warfare ship (or amphib) is an amphibious vehicle warship employed to land and support ground forces, such as marines, on enemy territory during an amphibious assault. Specialized shipping can be divided into two types, most crudely described as ships and craft. In general, the ships carry the troops from the port of embarkation to the drop point for the assault and the craft carry the troops from the ship to the shore. Amphibious assaults taking place over short distances can also involve the shore-to-shore technique, where landing craft go directly from the port of embarkation to the assault point. Some tank landing ships may also be able to land troops and equipment directly onto shore after travelling long distances, such as the . History In the days of sail, ship's boats were used as landing craft. These rowing boats were sufficient, if inefficient, in an era when marines were effectively light infantry, participating mostly in small-scale campaigns in far-fl ...

Landing Craft Utility
A Landing Craft Utility (LCU) is a type of boat used by amphibious forces to transport equipment and troops to the shore. They are capable of transporting tracked or wheeled vehicles and troops from amphibious assault ships to beachheads or piers. Colombia The Golfo de Tribugá-class landing craft is an LCU developed by COTECMAR for the Colombian National Navy. The vessel class is also known as BDA ( es, Buque de Desembarco Anfibio) and an unarmored version for logistical and humanitarian services has also been developed, known as BALC ( es, Buque de Apoyo Logístico y Cabotaje). Operators *: 5 in service, 1 on order *: 1 in service *: 2 in service France The Engin de débarquement amphibie rapide (EDA-R) landing catamaran or L-CAT, entered service in January 2011. They can carry a main battle tank like other European LCUs but are capable of much higher speeds, up to . Germany Germany has two Barbe-class utility landing craft (Type 520), dating from the mid-1960s, which re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FFG(X)
The ''Constellation'' class is a class of multi-mission guided-missile frigates under development for the United States Navy as a follow-on to the modular littoral combat ship. The U.S. Navy announced the FFG(X) frigate project in the United States Department of Defense Request For Information (RFI) on 10 July 2017. The U.S. Navy selected five shipbuilders to evolve their designs into a prospective design for the proposed twenty FFG(X) guided-missile frigates. On 30 April 2020, it was announced that Fincantieri Marinette Marine had won the contract with its FREMM multipurpose frigate-based design. The project was later renamed FFG-62 program after the lead ship was named. Development The U.S. Navy procured the first FFG 62 in FY2020, the next was awarded in April 2021, and the third is planned to be awarded is FY22. The U.S. Navy's proposed FY2020 budget request was $1.281 billion for the procurement of the first FFG 62. The U.S. Navy's FY2020 budget submission shows that sub ...

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, ...

High Temperature Superconductor
High-temperature superconductors (abbreviated high-c or HTS) are defined as materials that behave as superconductors at temperatures above , the boiling point of liquid nitrogen. The adjective "high temperature" is only in respect to previously known superconductors, which function at even colder temperatures close to absolute zero. In absolute terms, these "high temperatures" are still far below ambient, and therefore require cooling. The first high-temperature superconductor was discovered in 1986, by IBM researchers Johannes Georg Bednorz, Bednorz and Karl Alexander Müller, Müller, who were awarded the Nobel Prize in Physics in 1987 "for their important break-through in the discovery of superconductivity in ceramic materials". Most high-c materials are type-II superconductors. The major advantage of high-temperature superconductors is that they can be cooled by using liquid nitrogen, as opposed to the previously known superconductors which require expensive and hard-to ...
