USHUS
USHUS is an integrated sonar system developed by the Naval Physical and Oceanographic Laboratory (NPOL) of the Defence Research and Development Organisation (DRDO), India, for use in submarines of the Indian Navy. It is primarily designed to be used in Sindhughosh class submarines, though it is reported to be fitted in the ''Arihant''-class nuclear-powered ballistic missile submarines as well. USHUS is reported to be superior to its Russian equivalents. Design and description USHUS is used for detecting and tracking enemy submarines, surface vessels, and torpedoes and can be used for underwater communication and avoiding obstacles. The sonar can work in both active and passive mode, and is capable of interception and underwater communication. It can detect both surface ships and submarines at a range of a few kilometres. The team developing the sonar was awarded the ''Agni Award for self-reliance'' by the Indian Prime Minister in May 2007. Production The production of the ...

INS Arihant
INS ''Arihant'' (SSBN 80) (Sanskrit: ''Vanquisher of Enemies''), designated S2 Strategic Strike Nuclear Submarine, is the lead ship of India's of nuclear-powered ballistic missile submarines. The 6,000 tonne vessel was built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in the port city of Visakhapatnam. Arihant was launched on 26 July 2009, the anniversary of '' Vijay Diwas'' (Kargil War Victory Day) by Prime Minister Manmohan Singh. After fitting out and extensive sea trials, on 23 February 2016, she was confirmed as ready for operations, commissioned in August 2016, and deployed operationally in 2018. Design INS ''Arihant'' is the first of the planned five in the class of submarines designed and constructed as a part of the Indian Navy's secretive Advanced Technology Vessel (ATV) project. The ATV project was set up in 1984, under Vice Admiral Mihir K. Roy as the first Director General. The submarines are reported to be based on the . The ...

Arihant-class Submarine
The ''Arihant''-class ( in Sanskrit) is a class of Indian nuclear-powered ballistic missile submarines being built for the Indian Navy. They were developed under the ''Advanced Technology Vessel'' (ATV) project to design and build nuclear-powered submarines. These vessels are classified as 'strategic strike nuclear submarines' by India. The lead vessel of the class, was launched in 2009, and after extensive sea trials, was confirmed to be commissioned in August 2016. ''Arihant'' holds the distinction of being the first ballistic missile submarine to have been built by a country other than one of the five permanent members of the United Nations Security Council. History In December 1971, during the Indo-Pakistani War of 1971, US President Richard Nixon sent a carrier battle group named Task Force 74, led by the nuclear-powered into the international waters of the Bay of Bengal in a show of force. Task Force 74 remained in international waters, where it was legally entitled t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panchendriya (sonar)
Panchendriya (Literally '' 5 senses'' in Sanskrit) is a sonar suite that has been developed by the Defence Research and Development Organisation, India for the submarines of the Indian Navy. It has been described as India's "first indigenously developed sonar system for submarines". History The system has been developed by the Naval Physical Oceanographic Laboratory, Kochi a laboratory under the DRDO in the southern Indian state of Kerala. Initial approval for the project was given in 1987 for their induction into the Navy's Foxtrot-class submarines and was further approved as a measure to shore up indigenous production in sonar technology following a review in 1990. By 1994, development of engineering models and factory testing had been completed. Further tests on the system began in 1997 on board the INS Karanj with a scheduled induction for 2002. Features The Panchendriya is a composite submarine sonar and tactical weapons control system that contains active, passive, su ...

Sindhughosh Class Submarine
''Sindhughosh''-class submarines are diesel-electric submarines in active service with the Indian Navy. Their names are in Sanskrit, but in their Roman-alphabet forms sometimes a final short ''-a'' is dropped. The ''Sindhughosh'' submarines, designated 877EKM, were designed as part of ''Project 877'', and built under a contract between Rosvooruzhenie and the Ministry of Defence (India). The submarines have a displacement of 3,000 tonnes, a maximum diving depth of 300 meters, top speed of 18 knots, and are able to operate solo for 45 days with a crew of 53. The final unit was the first to be equipped with the 3M-54 Klub (SS-N-27) antiship cruise missiles with a range of 220 km. Life extension and refit INS ''Sindhuvijay'' has been upgraded with the hydro acoustical USHUS complex and the CCS-MK radio communications system. On 29 August 2014 DAC cleared the long-awaited mid-life upgrade of the four Kilo-class submarines, which would be carried out in Indian shipyards and ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Indian Rupee
The Indian rupee ( symbol: ₹; code: INR) is the official currency in the republic of India. The rupee is subdivided into 100 ''paise'' (singular: ''paisa''), though as of 2022, coins of denomination of 1 rupee are the lowest value in use whereas 2000 rupees is the highest. The issuance of the currency is controlled by the Reserve Bank of India. The Reserve Bank manages currency in India and derives its role in currency management on the basis of the Reserve Bank of India Act, 1934. Etymology The immediate precursor of the rupee is the ''rūpiya''—the silver coin weighing 178 grains minted in northern India by first Sher Shah Suri during his brief rule between 1540 and 1545 and adopted and standardized later by the Mughal Empire. The weight remained unchanged well beyond the end of the Mughals until the 20th century. Though Pāṇini mentions (), it is unclear whether he was referring to coinage.

Military Equipment Of India
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hindustan Shipyard
Hindustan Shipyard Limited (HSL) is a shipyard located in Visakhapatnam on the east coast of India. History Founded as the ''Scindia Shipyard'', it was built by industrialist Walchand Hirachand as a part of The Scindia Steam Navigation Company Ltd.
