French Frigate Alsace
''Alsace'' (D656) is an ''Aquitaine''-class frigate of the French Navy developed through the FREMM multipurpose frigate program. She is the first of two air-defence variants of the class known as FREMM DA (''Frégate Européenne Multimissions de Défense Aérienne'') in the program. Development and design Original plans were for 17 FREMM hulls to replace the nine avisos and nine anti-submarine (ASW) frigates of the and es. In November 2005 France announced a contract of €3.5 billion for development and the first eight hulls, with options for nine more costing €2.95 billion split over two tranches (totaling 17). Following the cancellation of the third and fourth of the s in 2005 on budget grounds, requirements for an air-defence derivative of the FREMM called FREDA were placed – with DCNS coming up with several proposals. Expectations were that the last two ships of the 17 FREMM planned would be built to FREDA specifications; however, by 2008 the plan was revised down ...

Alsace
Alsace (, ; ; Low Alemannic German/ gsw-FR, Elsàss ; german: Elsass ; la, Alsatia) is a cultural region and a territorial collectivity in eastern France, on the west bank of the upper Rhine next to Germany and Switzerland. In 2020, it had a population of 1,898,533. Alsatian culture is characterized by a blend of Germanic and French influences. Until 1871, Alsace included the area now known as the Territoire de Belfort, which formed its southernmost part. From 1982 to 2016, Alsace was the smallest administrative ''région'' in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin departments. Territorial reform passed by the French Parliament in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est. On 1 January 2021, the departments of Bas-Rhin and Haut-Rhin merged into the new European Collectivity of Alsace but remained part of the region Grand Est. Alsatian is an Alemannic dialect closely related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FREMM Multipurpose Frigate
The FREMM (French: ''Frégate Européenne Multi-Mission''; Italian: ''Fregata Europea Multi-Missione''), which stands for "European multi-purpose frigate", is a Franco-Italian family of multi-purpose frigates designed by Naval Group and Fincantieri. In France, this surface combatant is known as the "''Aquitaine'' class" (17 units planned, of which 9 were later cancelled), while in Italy it is known as the "''Bergamini'' class" (10 units planned). The lead ship of the class, , was commissioned in November 2012 by the French Navy. Italy has ordered six general purpose and four anti-submarine variants. France, on the other hand, has ordered six anti-submarine variants and two air-defense ones. The FREMM has also been exported to various countries. Notably, the United States Navy selected a FREMM variant for their new of 20 frigates, to be built by Fincantieri, starting with a $795 million contract for the lead ship. Background Three original variants of the FREMM were proposed; a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Houthi Movement
The Houthi movement (; ar, ٱلْحُوثِيُّون ''al-Ḥūthīyūn'' ), officially called Ansar Allah (' ''Partisans of God'' or ''Supporters of God'') and colloquially simply Houthis, is an Islamist, Islamist political and armed movement that emerged from Saada in Yemen Arab Republic, North Yemen in the 1990s. The Houthi movement is a predominately Zaidiyyah, Zaidi Shia Islam, Shia force, whose leadership is drawn largely from the Houthi tribe. The Houthis have a complex relationship with Yemen's Sunni Islam, Sunni Muslims; the movement has discriminated against Sunnis, but also recruited and allied with them. Under the leadership of Hussein Badreddin al-Houthi, the group emerged as an opposition to former Yemeni president Ali Abdullah Saleh. They accused him of corruption and criticized him for being backed by Saudi Arabia and the United States. Hussein accused Saleh of seeking to please the U.S. at the expense of the Yemeni people and Yemen's sovereignty. Resisting ...

Suez Canal
The Suez Canal ( arz, قَنَاةُ ٱلسُّوَيْسِ, ') is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. The long canal is a popular trade route between Europe and Asia. In 1858, Ferdinand de Lesseps formed the Suez Canal Company for the express purpose of building the canal. Construction of the canal lasted from 1859 to 1869. The canal officially opened on 17 November 1869. It offers vessels a direct route between the North Atlantic and northern Indian oceans via the Mediterranean Sea and the Red Sea, avoiding the South Atlantic and southern Indian oceans and reducing the journey distance from the Arabian Sea to London by approximately , or 10 days at to 8 days at . The canal extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez. In 2021, more than 20,600 vessels traversed the canal (an average of 56 per day). T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2023 Israel–Hamas War
} The ongoing armed conflict between Hamas-led Palestinian militant groups and Israel military forces began on 7 October 2023, 50 years after the start of the 1973 Yom Kippur War. Hamas's coordinated surprise offensive, codenamed "Al-Aqsa Flood", began in the morning with a barrage of at least 5,000 rockets launched from the Gaza Strip against Israel, while some 2,500 Palestinian militants breached the Gaza–Israel barrier, massacred and set fire to civilian communities, and attacked Israel Defense Forces (IDF) military bases near the Gaza Strip. Hamas stated that its attack was in response to the desecration of the Al-Aqsa Mosque, the blockade of the Gaza Strip, continued Israeli settlements, and Israeli settler violence. Over 1,400 Israelis, mostly civilians, were killed, including 260 people at a music festival in Re'im. Over 200 people, unarmed civilian hostages and captured Israeli soldiers, were taken to the Gaza Strip. Israeli military forces began conducting reta ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. The Mediterranean Sea e ... [...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] |
Ceremonial Ship 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 th ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
