Nuclear Attack Submarine
An SSN is a nuclear-powered general-purpose attack submarine. ''SSN'' is the US Navy hull classification symbol for such vessels; the ''SS'' (as 'Ship Submersible') denotes a submarine and the ''N'' denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166, though navies use other terms. History The first nuclear-powered attack submarine was the US Navy's , operational from 1954. This was followed by the four submarines of the entering service in 1957. The Royal Navy's first nuclear fleet submarine was which by using an American reactor entered service in 1963. The first all-British nuclear submarines were the two s. The USN submarine fleet has been all-nuclear powered for over three decades. The last Barbel-class diesel-electric attack submarine, , was decommissioned in 1990. The bulk of the USN's SSN fleet has been the ''Los Angeles''-class attack submarine. Designed during the Cold War the ''Los Angeles''-class boats ''raiso ...

Special Forces
Special forces or special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during World War II, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including Airborne forces, airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, Covert operations, covert ops, Direct action (military), direct action, Hostage crises, hostage rescue, high-value targets/Manhunt (military), manhunt, intelligence, surveillance, target acquisition, and reconnaissance, intelligence operations, Mobility (military), mobility o ...

SSN-AUKUS
The SSN-AUKUS, also known as the SSN-A, is a planned class of nuclear-powered attack submarine ( SSN) intended to enter service with the United Kingdom's Royal Navy in the late 2030s and Royal Australian Navy in the early 2040s. The class will replace the UK's and Australia's submarines. The UK commenced an ''Astute'' class replacement project in 2018, which was later named the Submersible Ship Nuclear Replacement (SSNR). The ongoing SSNR design was renamed SSN-AUKUS in March 2023, under the 2021 AUKUS trilateral security partnership, when Australia joined the programme and additional US technology was incorporated into the design. The UK plans to build up to twelve SSN-AUKUS submarines. Australia plans to build five SSN-AUKUS submarines in addition to acquiring three nuclear-powered submarines from the United States. When in service with the Royal Navy and the Royal Australian Navy, submarine crews will train and patrol together and undertake joint maintenance and support. ...

Sierra-class Submarine
The Sierra class, Soviet designations Project 945 ''Barrakuda'' and Project 945A ''Kondor'', (List of NATO reporting names for submarines, NATO reporting names Sierra I and Sierra II respectively), are a series of Nuclear submarine, nuclear-powered attack submarines intended for the Soviet Navy and currently in service with the Russian Navy. The class resembles the in having a light and strong titanium pressure hull which enables the submarines of the class to dive to greater depths, reduce the level of radiated noise and increase resistance to torpedo attacks. It is powered by a single OK-650 pressurized water reactor. The upgraded version, the Sierra II class was specifically developed for search and destroy missions against US nuclear submarines. It has speeds and diving depth greater than its American counterparts at the time it was designed. It has also improved quieting and sonar.

Victor-class Submarine
The Victor class, Soviet designations Project 671 ''Yorsh'', Project 671RT ''Syomga'' and Project 671RTM/RTMK ''Shchuka'', (List of NATO reporting names for submarines, NATO reporting names Victor I, Victor II and Victor III, respectively), are series of Nuclear submarine, nuclear-powered attack submarines built in the Soviet Union and operated by the Soviet Navy. Since the 1960s, 48 units were built in total, of which the last remaining are currently in service with the Russian Navy. The Victor-class submarines featured a Teardrop hull, teardrop shape, allowing them to travel at high speed. These vessels were primarily designed to protect Soviet surface fleets and to attack United States Navy, American ballistic missile submarines.

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 ...

SSN(X)-class Submarine
The SSN(X) or Next-Generation Attack Submarine program of the United States Navy aims to develop a new class of nuclear-powered attack submarine with vertical launch systems for cruise missiles to succeed the ''Virginia'' and '' Seawolf'' classes. The SSN(X) program remains in the early stages of development and no official details have been released about its design or capabilities. This program is expected to incorporate advanced technologies and capabilities to ensure that the new submarines will be able to meet the evolving challenges of the modern maritime environment. It is believed that the SSN(X) program will focus on improving stealth, sensor capabilities, and firepower to enable the new submarines to operate effectively in a variety of missions, including intelligence gathering, special operations, and anti-submarine warfare. Along with the ballistic missile submarine, the SSN(X) program is seen as a critical component of the Navy's future submarine force and is expec ...

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into 3 categories: low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity; intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding; and high-level waste (HLW), which is highly radioactive and hot due to decay heat, thus requiring cooling and shielding. Spent nuclear fuel can be processed in nuclear reprocessing plants. One third of the total amount have already been reprocessed. With nuclear reprocessing 96% of the spent fue ...

Nuclear Decommissioning
Nuclear decommissioning is the process leading to the irreversible complete or partial closure of a nuclear facility, usually a nuclear reactor, with the ultimate aim at termination of the operating licence. The process usually runs according to a ''decommissioning plan'', including the whole or partial dismantling and decontamination of the facility, ideally resulting in restoration of the environment up to greenfield status. The decommissioning plan is fulfilled when the approved end state of the facility has been reached. The process typically takes about 15 to 30 years, or many decades more when an interim ''safe storage'' period is applied for radioactive decay. Radioactive waste that remains after the decommissioning is either moved to an on-site storage facility where it is still under control of the owner, or moved to a dry cask storage or disposal facility at another location. The final disposal of nuclear waste from past and future decommissioning is a growing still un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
