Underwater Warfare
Underwater warfare is one of the three operational areas of naval warfare, the others being surface warfare and aerial warfare. It refers to combat conducted underwater such as: *Actions by submarines actions, and anti-submarine warfare, i.e. warfare between submarines, other submarines and surface ships; combat airplanes and helicopters may also be engaged when launching special dive-bombs and torpedo-missiles against submarines; *Underwater special operations, considering: **Military diving sabotage against ships and ports. **Anti-frogman techniques. **Reconnaissance tasks. Name Underwater warfare may also be referred to as undersea warfare or subsurface warfare. History In the 20th century underwater warfare was dominated by the submarine. In the 21st century unmanned underwater vehicles are coming to play a significant part in underwater warfare. Seabed warfare Seabed warfare is defined as “operations to, from and across the ocean floor.” In general the target of sea ...

Virginia Class Submarine
The ''Virginia'' class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the ''Virginia'' class is the United States Navy's latest submarine model, which incorporates the latest in stealth, intelligence gathering, and weapons systems technology. ''Virginia''-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. They are scheduled to replace older s, many of which have already been decommissioned. ''Virginia''-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to remain into the 2070s. History The class was developed under the codename Centurion, later renamed New SSN (NSSN). The "Centurion Study" was initiated i ...

Military Diving
Underwater divers may be employed in any branch of an armed force, including the navy, army, marines, air force and coast guard. Scope of operations includes: search and recovery, search and rescue, hydrographic survey, explosive ordnance disposal, demolition , underwater engineering, salvage, ships husbandry, reconnaissance, infiltration, sabotage, counterifiltration, underwater combat and security. History of military diving Military divers are essential to many missions and campaigns. Combat and demolition work, underwater and coastal reconnaissance, ordnance disposal, search and rescue, salvage operations, construction, ship maintenance and underwater engineering. Every branch of the U.S. military employs divers, and more than 40 nations have military diving units. Military diving is an occupation that has risks and responsibilities beyond those of other professional diving. Research and development in military diving equipment and procedures often eventually contributes to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spetsnaz
Spetsnaz are special forces in numerous post-Soviet states. (The term is borrowed from rus, спецназ, p=spʲɪtsˈnas; abbreviation for or 'Special Purpose Military Units'; or .) Historically, the term ''spetsnaz'' referred to the Soviet Union's Special Forces of the Main Directorate of the General Staff of the Russian Armed Forces, Spetsnaz GRU, special operations units of the Main Intelligence Directorate (GRU), GRU, the main military intelligence service. It also describes task forces of other ministries (such as the Ministry of Internal Affairs (Russia), Ministry of Internal Affairs' ODON and Ministry of Emergency Situations (Russia), Ministry of Emergency Situations' special rescue unit) in post-Soviet countries. As ''spetsnaz'' is a Russian term, it is typically associated with the special units of Russia, but other post-Soviet states often refer to their special forces units by the term as well, since these nations also inherited their special purpose units fro ...

Naval Tactics
Naval tactics and doctrine is the collective name for methods of engaging and defeating an enemy ship or fleet in battle at sea during naval warfare, the naval equivalent of military tactics on land. Naval tactics are distinct from naval strategy. Naval tactics are concerned with the movements a commander makes in battle, typically in the presence of the enemy. Naval strategy concerns the overall strategy for achieving victory and the large movements by which a commandant or commander secures the advantage of fighting at a place convenient to himself. Modern naval tactics are based on tactical doctrines developed after World War II, following the obsolescence of the battleship and the development of long-range missiles. Since there has been no major naval conflict since World War II, apart from the Indo-Pakistani Naval War of 1971 and the Falklands War, many of these doctrines reflect scenarios developed for planning purposes. Critics argue that the collapse of the Soviet Union ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Military Special Forces Units
This is a list of military special forces units, also known as special operations forces (SOF), currently active with countries around the world, that are specially organised, trained and equipped to conduct special operations. These are distinct from special-purpose infantry units, such as the Royal Marine Commandos, found on the list of commando units, and also paratrooper units found on the list of paratrooper forces. Definitions NATO currently defines "special operations" as: Military activities conducted by specially designated, organized, trained, and equipped forces, manned with selected personnel, using unconventional tactics, techniques, and modes of employment. In 2001, as part of efforts to create a framework for consultation and cooperation between NATO and Russia, the ''NATO-RUSSIA Glossary of Contemporary Political and Military Terms'' further defined special operations and special operations forces: special operations military activities conducted by speci ...

Frogman
A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word ''frogman'' first arose in the stage name ''The Fearless Frogman'' of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit. The term ''frogman'' is occasionally used to refer to a civilian scuba diver. Some sport diving clubs include the word ''Frogmen'' in their names. The preferred term by scuba users is ''diver'', but the ''frogman'' epithet persists in informal usage by non-divers, especially in the media and often referring to professional scuba divers, such as in a police diving role.

Originally "a commando" was a type of combat unit, as opposed to an individual in that unit. In other languages, ''commando'' and ''kommando'' denote a "command", including the sense of a military or an elite special operations unit. In the militaries and governments of most countries, commandos are distinctive in that they specialize in unconventional assault on high-value targets. In English, to distinguish between an individual commando and a commando unit, the unit is occasionally capitalized. Etymology From an ancient lingual perspective the term commando derives from Latin ''commen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Underwater Vehicle
Unmanned underwater vehicles (UUV), sometimes known as underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input. Classifications Remotely operated underwater vehicle Remotely Operated Underwater Vehicles (ROUVs) is a subclass of UUVs with the primary purpose of replacing humans for underwater tasks due to the difficult underwater conditions. ROUVs are designed to perform educational or industrial missions. They are manually controlled by an operator to perform tasks that include surveillance and patrolling. The structure of ROUVs disqualify it from being able to operate autonomously. In addition to a camera, actuators, and sensors, ROUVs often include a “gripper” or something ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...

Anti-frogman Techniques
Defenses against swimmer incursions are security methods developed to protect watercraft, ports and installations, and other sensitive resources in or near vulnerable waterways from potential threats or intrusions by swimmers or scuba divers. Risks and threats The need for military underwater security was demonstrated in World War II by the achievements of frogmen against armed forces facilities such as the Italian frogman actions in WWII. Since the late 1950s, the increasing demand for and availability of sophisticated scuba diving equipment has also created concerns about protecting valuable underwater archaeology sites and shellfish fishing stocks. The 12 October 2000 USS Cole bombing was not carried out by underwater divers, but did bring renewed attention to the vulnerability they present for naval ships. Divers can swim 100 to 200 yards in about three minutes, and large sonar ranges would be required around ships for security forces to detect underwater swimmers in time ...

Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Sabotage
Sabotage is a deliberate action aimed at weakening a polity, effort, or organization through subversion, obstruction, disruption, or destruction. One who engages in sabotage is a ''saboteur''. Saboteurs typically try to conceal their identities because of the consequences of their actions and to avoid invoking legal and organizational requirements for addressing sabotage. Etymology The English word derives from the French word , meaning to "bungle, botch, wreck or sabotage"; it was originally used to refer to labour disputes, in which workers wearing wooden shoes called interrupted production through different means. A false etymology, popular but incorrect account of the origin of the term's present meaning is the story that poor workers in the Belgian city of Liège would throw a wooden into the machines to disrupt production. One of the first appearances of and in French literature is in the of d'Hautel, edited in 1808. In it the literal definition is to 'make nois ...
