Mark 45 Torpedo
The Mark 45 anti-submarine torpedo, a.k.a. ASTOR, was a submarine-launched wire-guided nuclear torpedo designed by the United States Navy for use against high-speed, deep-diving, enemy submarines. This was one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The -diameter torpedo was fitted with a W34 nuclear warhead. The need to maintain direct control over the warhead meant that a wire connection had to be maintained between the torpedo and submarine until detonation. Wire guidance systems were piggybacked onto this cable, and the torpedo had no homing capability. The design was completed in 1960, and 600 torpedoes were built between 1963 and 1976, when ASTOR was replaced by the Mark 48 torpedo. Design This electrically propelled, -diameter torpedo was long and weighed .Kurak (September 1966) p.147Polmar (November 1978) p.160 The W34 nuclear warhead used in ASTOR had an explosive yield of 11 kilotons.

Nuclear Torpedo
A nuclear torpedo is a torpedo armed with a nuclear warhead. The idea behind the nuclear warheads in a torpedo was to create a much bigger explosive blast. Later analysis suggested that smaller, more accurate, and faster torpedoes were more efficient and effective. During the Cold War, nuclear torpedoes replaced some conventionally armed torpedoes on submarines of both the Soviet and American navies. The USSR developed the T15, the T5 and the ASB-30. The only nuclear warhead torpedo used by the United States was the Mark 45 torpedo. The Soviet Union widely deployed T5 nuclear torpedoes in 1958 and the U.S. deployed its Mark 45 torpedo in 1963. In 2015, there were rumors that Russia was developing a new nuclear torpedo, the Status-6. Soviet Union T-15 The Soviet Union's development of nuclear weapons began in the late 1940s. The Navy had put itself forward as the most suitable branch of the Soviet armed forces to deliver a nuclear strike, believing its submarine technology and ...

Torpedoes Of The United States
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though so ...

American 21 Inch Torpedo
There have been a number of 21-inch torpedoes in service with the United States. These have been used on ships and submarines of the U.S. Navy. American 21-inch torpedoes are in diameter. Ship classes that carried 21-inch torpedoes include: * ''Allen M. Sumner''-class destroyers * ''Atlanta''-class cruisers * ''Bagley''-class destroyers * ''Balao''-class submarines * ''Barbel''-class submarines * ''Barracuda''-class submarines * ''Benham''-class destroyers * ''Benjamin Franklin''-class submarines * ''Benson''-class destroyers * ''Cachalot''-class submarines * ''Caldwell''-class destroyers * ''Cassin''-class destroyers * ''Chester''-class cruisers * ''Clemson''-class destroyers * ''Colorado''-class battleships * ''Connecticut''-class battleships * ''Dealey''-class destroyer escorts * ''Ethan Allen''-class submarines * ''Farragut''-class destroyers * ''Forrest Sherman''-class destroyers * ''Fletcher''-class destroyers * ''Gato''-class submarines * ''Gearing''-class destroyers * ''Ge ...

Wake Homing
Wake homing is a torpedo guidance technique based on the wake trajectory left behind a moving target. The torpedo is fired to cross behind the stern of the target ship, through the wake. As it does so, it uses sonar to look for changes in the water caused by the passage of the ship, such as small air bubbles. When these are detected, the torpedo turns toward the ship. It then follows a zig-zag course, turning when it detects the outer edge of the wake, to keep itself in the wake while moving forward. This will eventually bring it to the stern of the ship, where its warhead can do the most damage to propulsion and steering. Advantages and disadvantages The system is difficult to jam, but it can be distracted by other ships crossing the wake. In 2013, the US Navy tested prototypes of a system known as the Countermeasure Anti-Torpedo (CAT), which had been designed to intercept and destroy the incoming torpedo. Deployment of the system did not proceed as planned due to performanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. *** Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig- ...

Mark 48 Torpedo
The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships. History The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology. Operational since 1972, it replaced the Mk-37, Mk-14 and Mk-16 torpedoes as the principal weapon of U.S. Navy submarines. With the entry into service of the new Soviet in 1977, the decision was made to accelerate the ADCAP program, which would bring significant modifications to the torpedo. Tests were run to ensure that the weapon could keep up with the developments and the weapon was modified with improved acoustics and electronics. The new v ...

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 1 ... [...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 e ... [...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-laun ...
