Mk 46 Torpedo
The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance. The Mark 46 was initially developed as Research Torpedo Concept I (RETORC I), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare.

M249 Light Machine Gun
The M249 light machine gun (LMG), also known as the M249 Squad Automatic Weapon (SAW), which continues to be the manufacturer's designation, and formally written as Light Machine Gun, 5.56 mm, M249, is the American adaptation of the Belgian FN Minimi, a light machine gun manufactured by the Belgian company FN Herstal (FN). The M249 is manufactured in the United States by the subsidiary FN Manufacturing LLC, a company in Columbia, South Carolina, and is widely used in the U.S. Armed Forces. The weapon was introduced in 1984 after being judged most effective (compared to a number of candidate weapons) to address the lack of automatic firepower in small units. The M249 provides infantry squads with a high rate of machine gun fire, combined with the accuracy and portability of a rifle. The M249 is gas operated and air-cooled, it has a quick-change barrel (allowing the gunner to rapidly replace an overheated or jammed barrel), and a folding bipod attached to the front of the w ...

Sea Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

CAPTOR Mine
The Mark 60 CAPTOR (Encapsulated Torpedo) is the United States' only deep-water anti-submarine naval mine. It uses a Mark 46 torpedo contained in an aluminum shell that is anchored to the ocean floor. The mine can be placed by either aircraft, submarine or surface vessel. The torpedo, once placed, can last anywhere from weeks to months underwater. The original production contract of the CAPTOR mine was awarded to Goodyear Aerospace Goodyear Aerospace Corporation (GAC) was the aerospace and defense subsidiary of the Goodyear Tire and Rubber Company. The company was originally operated as a division within Goodyear as the Goodyear Zeppelin Corporation, part of a joint project ... in 1972, and entered service in 1979. It was hoped to reduce minefield costs and used in the creation of a barrier of the "Greenland-Iceland-United Kingdom gap to interrupt Soviet submarines in the event that deterrence failed." The mine uses Reliable Acoustic Path (RAP) sound propagation to passively i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yu-7 Torpedo
The Yu-7 (; from ) is a lightweight torpedo developed by the People's Republic of China. It entered service in the 1990s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships. The Yu-7 is a derivative of the Whitehead Alenia Sistemi Subacquei (WASS) A244/S torpedo. Development Development of an effective lightweight anti-submarine (ASW) torpedo for the PLAN began in the 1980s. The program was probably based on 40 A244/S torpedoes purchased for evaluation from Italy in 1987. Additional technology may have been reverse engineered from a United States Mark 46 Mod 2 torpedo recovered from the South China Sea in 1978 by Chinese fishermen. The torpedo was initially equipped with electric propulsion, but inadequate performance led to a redesign powered by Otto fuel II. Testing was carried out at the 750 Testing Range in Kunming up to 1988. Description The Yu-7 has contrarotating propellers. Aboard surface warships, it is fired from Type 7424 tr ...

ASROC
The RUR-5 ASROC (for "Anti-Submarine Rocket") is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, the Republic of China, Greece, Pakistan and others. History ASROC started development as the Rocket Assisted Torpedo (RAT) program by the Naval Ordnance Test Station at China Lake in the early 1950s to develop a surface warship ASW weapon to counter the new post-World War II submarines which ran quieter, at much higher speed and could attack from much longer range with high speed homing torpedoes. In addition, the goal was to take advantage of modern sonars with a much larger detection range. An extended range torpedo delivered by parachute from th ...

Annapolis, Maryland
Annapolis ( ) is the capital city of the U.S. state of Maryland and the county seat of, and only incorporated city in, Anne Arundel County. Situated on the Chesapeake Bay at the mouth of the Severn River, south of Baltimore and about east of Washington, D.C., Annapolis forms part of the Baltimore–Washington metropolitan area. The 2020 census recorded its population as 40,812, an increase of 6.3% since 2010. This city served as the seat of the Confederation Congress, formerly the Second Continental Congress, and temporary national capital of the United States in 1783–1784. At that time, General George Washington came before the body convened in the new Maryland State House and resigned his commission as commander of the Continental Army. A month later, the Congress ratified the Treaty of Paris of 1783, ending the American Revolutionary War, with Great Britain recognizing the independence of the United States. The city and state capitol was also the site of the 1786 An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Warfare
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures. Submarine warfare consists primarily of diesel and nuclear submarines using torpedoes, missiles or nuclear weapons, as well as advanced sensing equipment, to attack other submarines, ships, or land targets. Submarines may also be used for reconnaissance and landing of special forces as well as deterrence. In some navies they may be used for task force screening. The effectiveness of submarine warfare partly depends on the anti-submarine warfare carried out in response. American Civil War The age of submarine warfare began during the American Civil War. The 1860s was a time of many turning points in terms of how naval warfare was fought. Many new types of warships were being developed for use in the United States and Confederate States Navies. Submarine watercraft were among the newly created vessels. The first sinking of an enemy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Nobska
Project Nobska was a 1956 summer study on anti-submarine warfare (ASW) for the United States Navy ordered by Chief of Naval Operations Admiral Arleigh Burke. It is also referred to as the Nobska Study, named for its location on Nobska Point near the Woods Hole Oceanographic Institution (WHOI) on Cape Cod, Massachusetts. The focus was on the ASW implications of nuclear submarines, particularly on new technologies to defend against them. The study was coordinated by the Committee on Undersea Warfare (CUW) of the National Academy of Sciences (NAS). It was notable for including 73 representatives from numerous organizations involved in submarine design, submarine-related fields, and weapons design, including senior scientists from the Atomic Energy Commission's nuclear weapons laboratories. Among the participants were Nobel laureate Isidor Rabi, Paul Nitze, and Edward Teller. The study's recommendations influenced all subsequent US Navy submarine designs, as well as submarine-launche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Torpedo
An aerial torpedo (also known as an airborne torpedo or air-dropped torpedo) is a torpedo launched from a torpedo bomber aircraft into the water, after which the weapon propels itself to the target. First used in World War I, air-dropped torpedoes were used extensively in World War II, and remain in limited use. Aerial torpedoes are generally smaller and lighter than submarine- and surface-launched torpedoes. History Origins The idea of dropping lightweight torpedoes from aircraft was conceived in the early 1910s by Bradley A. Fiske, an officer in the United States Navy.Hopkins, Albert Allis.
