Ohio-class Submarines
The ''Ohio'' class of nuclear submarine, nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its 4 cruise missile submarines (SSGNs). Each Displacement (ship), displacing 18,750 tons submerged, the ''Ohio''-class boats are the largest submarines ever built for the U.S. Navy and are capable of carrying 24 UGM-133 Trident II, Trident II missiles apiece. They are also the third-largest submarines ever built, behind the Russian Navy's Soviet Union, Soviet era 48,000-ton , the last of which was retired in 2023, and 24,000-ton . Like their predecessors the and es, the ''Ohio''-class SSBNs are part of the United States' Nuclear triad, nuclear-deterrent triad, along with U.S. Air Force strategic bombers and intercontinental ballistic missiles. The 14 SSBNs together carry about half of U.S. active strategic Thermonuclear weapon, thermonuclear warheads. Although the Trident missiles have no preset targets when the submarines go on patro ...

Good Luck Ohio
In most contexts, the concept of good denotes the conduct that should be preferred when posed with a choice between possible actions. Good is generally considered to be the opposite of evil. The specific meaning and etymology of the term and its associated translations among ancient and contemporary languages show substantial variation in its inflection and meaning, depending on circumstances of place and history, or of philosophical or religious context. History of Western ideas Every language has a word expressing ''good'' in the sense of "having the right or desirable quality" (Arete (moral virtue), ἀρετή) and ''bad'' in the sense "undesirable". A sense of morality, moral judgment and a distinction "right and wrong, good and bad" are cultural universals. Plato and Aristotle Although the history of the origin of the use of the concept and meaning of "good" are diverse, the notable discussions of Plato and Aristotle on this subject have been of significant historic ...

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 ...

Russian Navy
The Russian Navy is the Navy, naval arm of the Russian Armed Forces. It has existed in various forms since 1696. Its present iteration was formed in January 1992 when it succeeded the Navy of the Commonwealth of Independent States (which had itself succeeded the Soviet Navy following the dissolution of the Soviet Union in late December 1991). The Imperial Russian Navy was established by Peter the Great (Peter I) in October 1696. The symbols of the Russian Navy, the St. Andrew's ensign (seen to the right), and most of its traditions were established personally by Peter I. The Russian navy possesses the vast majority of the former Soviet naval forces, and currently comprises the Northern Fleet, the Pacific Fleet (Russia), Pacific Fleet, the Black Sea Fleet, the Baltic Fleet, the Caspian Flotilla, the Permanent task force of the Russian Navy in the Mediterranean Sea, permanent task force in the Mediterranean, Russian Naval Aviation, Naval Aviation, and the Coastal Troop ...

UGM-133 Trident II
The UGM-133A Trident II, or Trident D5 is a submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space in Sunnyvale, California, and deployed with the United States Navy and Royal Navy. It was first deployed in March 1990, and remains in service. The Trident II Strategic Weapons System is an improved SLBM with greater accuracy, payload, and range than the earlier Trident C-4. It is a key element of the U.S. strategic nuclear triad and strengthens U.S. strategic deterrence. The Trident II is considered to be a durable sea-based system capable of engaging many targets. It has payload flexibility that can accommodate various treaty requirements, such as New START. The Trident II's increased payload allows nuclear deterrence to be accomplished with fewer submarines, and its high accuracy—approaching that of land-based missiles—enables it to be used as a first strike weapon. Trident II missiles are carried by 14 US and 4 British submarines, with 24 missi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Cruise Missile Submarine
A cruise missile submarine is a submarine that carries and launches cruise missiles (Submarine-launched cruise missile, SLCMs consisting of land-attack cruise missiles and anti-ship missiles) as its primary armament. Missiles greatly enhance a warship's ability to attack surface combatants and strike land targets; although torpedoes are a more discreet option for submerged submarines, missiles give a much longer Standoff missile, stand-off range, shorter time to impact the target, as well as the ability to engage multiple targets on different headings at the same time. Many cruise missile submarines retain the capability to deploy Nuclear weapons delivery, nuclear warheads on their missiles, but they are considered distinct from ballistic missile submarines due to the substantial differences between the two weapons systems' flight characteristics; cruise missiles fly aerodynamically using flight surfaces like wings or fins, while a ballistic missile uses its engine power alone as ...

Ballistic Missile Submarine
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of ballistic missile submarines is dominated by the United States, Russia (following the collapse of the Soviet Union) and China. In fact, 70% of nuclear warheads in the USA are carried by ballistic missile submarines.Rafal, A. S. (2021).

Nuclear Submarine
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a virtually unlimited range, making the only limits on voyage times factors such as the need to restock food or other consumables. Thus nuclear propulsion solves the problem of limited mission duration that all electric ( battery or fuel cell powered) submarines face. The high cost of nuclear technology means that relatively few of the world's military powers have fielded nuclear submarines. Radiation incidents have occurred wit ...

Tomahawk (missile Family)
The BGM-109 Tomahawk () Land Attack Missile (TLAM) is an American long-range, all-weather, jet-powered, Subsonic flight, subsonic cruise missile that is primarily used by the United States Navy and Royal Navy in ship and submarine-based land-attack operations. Developed at the Applied Physics Laboratory of Johns Hopkins University under James H. Walker near Laurel, Maryland, the Tomahawk emerged in the 1970s as a modular cruise missile first manufactured by General Dynamics. The Tomahawk aimed to fulfill the need for a medium- to long-range, low-altitude missile with diverse capabilities. Its modular design allows for compatibility with a range of warheads, including high-explosive, submunitions, and bunker-busters. The Tomahawk can use a variety of guidance systems, including Global Positioning System, GPS, Inertial navigation system, inertial navigation, and TERCOM, terrain contour matching. Over a dozen variants and upgraded versions have been developed since the original desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MIRV
A multiple independently targetable reentry vehicle (MIRV) is an exoatmospheric ballistic missile payload containing several warheads, each capable of being aimed to hit a different target. The concept is almost invariably associated with intercontinental ballistic missiles carrying thermonuclear warheads, even if not strictly being limited to them. An intermediate case is the multiple reentry vehicle (MRV) missile which carries several warheads which are dispersed but not individually aimed. All nuclear-weapon states except Pakistan and North Korea are currently confirmed to have deployed MIRV missile systems. The first true MIRV design was the Minuteman III, first successfully tested in 1968 and introduced into actual use in 1970. The Minuteman III held three smaller W62 warheads, with yields of about each in place of the single W56 used on the Minuteman II. From 1970 to 1975, the United States would remove approximately 550 earlier versions of the Minuteman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
