Amur-class Submarine
The ''Amur''-class submarine (named for the Amur River), is one of the latest Russian submarine designs. It is advertised as an export version of the , a modernized version of the with improved acoustic stealth, new combat systems, and an option for air-independent propulsion (AIP). The new vessels are the fourth generation of the Kilo submarine family, with two models developed. As advertised, the ''Amur''-1650 is larger and intended for longer missions. The ''Amur''-950 is armed with a VLS missile system capable of salvo-fire at multiple predesignated targets. Sonar signatures of these submarines are several times lower than the older Kilo-class submarines. Both designs are equipped with electronic warfare armament of the newer generation created on the basis of the latest science and technology. They can be outfitted with AIP fuel cells, considerably improving submerged endurance and range. AIP capability can be added in a hull extension plug either during new build construct ...

Rubin Design Bureau
Rubin Central Design Bureau for Marine Engineering (Russian: Центральное конструкторское бюро "Рубин", shortened to ЦКБ "Рубин") in Saint Petersburg is one of three main Russian centers of submarine design, and the other two are Malakhit Marine Engineering Bureau and Lazurit Central Design Bureau ("Lazurit" is the Russian word for lazurite). Rubin is the largest among the three Soviet/Russian submarine designer centers, having designed more than two-thirds of all nuclear submarines in the Russian Navy. "Rubin" (russian: Рубин) is the Russian word for ruby. History Early history On January 4, 1901 the Marine Ministry of Russia assigned the task of designing a combat submarine for the Russian Navy to three officers: Lieutenant M.N. Beklemishev, Lieutenant I.S. Goryunov and naval architect Senior Assistant I.G. Bubnov, an employee at the Ministry's Baltic Shipyard where the construction of the vessel was planned to take place.

Kalvari-class Submarine (2015)
The ''Kalvari'' class is a class of diesel-electric attack submarines based on the being built for the Indian Navy. The class and submarines take their names from the first submarines inducted in the Indian Navy. The submarines are designed by French naval defence and energy company DCNS and are being manufactured by Mazagon Dock Limited in Mumbai. Project history In 1997, Indian Ministry of Defence approved a plan to acquire 24 submarines under Project 75. In 1998, India began negotiating with DCN for four Scorpène submarines with two to be built in Mazagon Dock Limited from knocked-down kits. After the Kargil War in 1999, Cabinet Committee on Security approved a 30-year submarine building plan that called for two parallel production lines, each constructing six submarines. The older Project 75 was brought under the new plan, with the two production lines to be built under Project 75 and Project 75I using transfer of technology from different foreign manufacturers.

Cruise Missile Submarine
A cruise missile submarine is a submarine that carries and launches cruise missiles (SLCMs and anti-ship missiles) as its primary armament. Missiles greatly enhance a vessel's ability to attack surface combatants and strike land targets, and although torpedoes are a more stealthy option, missiles give a much longer stand-off range, 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 warheads on their missiles, but they are considered distinct from ballistic missile submarines due to the substantial differences between the two weapons systems' characteristics. Originally early designs of cruise missile submarines had to surface to launch their missiles, while later designs could do so underwater via dedicated vertical launching system (VLS) tubes. Many modern attack submarines can launch cruise missiles (and dedicated anti-ship missiles) from their torpedo tubes while some ...

Future Of The Russian Navy
Following the dissolution of the Soviet Union at the end of 1991, the Russian Navy struggled to adjust Cold War force structures while suffering severely with insufficient maintenance and a lack of funding. However, improvements in the Russian economy over the first decade of the twenty-first century led to a significant rise in defence expenditure and an increase in the number of ships under construction (with a focus on blue-water vessels). An extensive rearmament program was implemented after 2011, with the Russian Defence Ministry expected to procure 100 warships by 2020. In early 2013 it was reported that the navy was to receive 54 new warships of various classes plus 24 submarines by 2020. A report by the US Navy's Office of Naval Intelligence issued in December 2015 provided descriptions and timelines for the construction of a modern 21st century Russian Navy. Some of these plans were modified over the course of the decade with delays pushing back the procurement of major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Soviet And Russian Submarine Classes
Submarines of the Soviet Navy were developed by numbered "projects", which were sometimes but not always given names. During the Cold War, NATO nations referred to these classes by NATO reporting names, based on intelligence data, which did not always correspond with the projects. See: * List of NATO reporting names for ballistic missile submarines * List of NATO reporting names for guided missile submarines * List of NATO reporting names for hunter-killer and experimental submarines The NATO reporting names were based on the British (and later American) habit of naming submarines with a letter of the alphabet indicating the class, followed by a serial number of that class. The names are the radiotelephonic alphabet call sign of a letter of the alphabet. For security purposes, the "pennant numbers" of Soviet submarines were not sequential, any more than those of Soviet surface vessels were. Most Russian (and Soviet) submarines had no "personal" name, but were only known by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandanor
Tandanor (an acronym for Talleres Navales Dársena Norte) is an Argentine shipyard located south of Buenos Aires port which together with Almirante Storni yard constitutes CINAR (Argentina's Industrial and Naval Compound) dedicated to shipbuilding and ship repair. It currently harbors ships from around the globe due to its international renown. Its competitive advantage springs from its Syncrolift: a shiplifting platform that allows vessels to be dry docked and perform simultaneous repairs on its six slipways. In April 2019, Tandanor signed a cooperation agreement with City Bank. History The company was established as "Talleres Navales de Marina" on November 10, 1879, during the presidency of Nicolás Avellaneda for the maintenance of Navy of Argentina ships. In 1922 it was renamed "Arsenal Naval Buenos Aires", then establishing as a "sociedad anónima" under its current denomination, with majority of state-capital injection in 1971.Centro de Estudios para la Producción (200 ...

Energy Conversion Efficiency
Energy conversion efficiency (''η'') is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, ''η'' (eta), ranges between 0 and 1. Overview Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle. Energy converter is an example of an energy transformation. For example, a light bulb falls into the categories energy converter. \eta = \frac Even though the definition includes the notion of usefulness, efficiency is considered a technical or physical term. Goal or mission oriented terms include effectiveness and efficacy. Generally, energy conversion efficiency is a dimensionless number between 0 and 1.0, or 0% to 100%. Ef ...
