Advanced Light Torpedo Shyena
The Advanced Light Torpedo (TAL) Shyena (Sanskrit: श्येन, "Falcon or Hawk") is the first indigenous advanced lightweight anti-submarine torpedo of India, developed by the Naval Science and Technological Laboratory (NSTL) of the Defence Research and Development Organisation (DRDO) for the Indian Navy. The lightweight torpedo can be launched by ships, submarines, helicopters and Ilyushin Il-38, named after the divine hawk identified with Agni. Introduction Shyena is a processor based torpedo which incorporates solid-state electronics, digital technology and has been equipped with an integrated Active/Passive sensor package for homing. It is designed to be capable of being launched from both a helicopter or from a triple-tube launcher on surface vessels. Its key design feature are maneuverability and ability to transition from warm to cold medium to ensure a hunt and kill. The development period of the torpedo was quite long, starting in the 1990s, and was inducted into t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
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 ...

Hyderabad
Hyderabad ( ; , ) is the capital and largest city of the Indian state of Telangana and the ''de jure'' capital of Andhra Pradesh. It occupies on the Deccan Plateau along the banks of the Musi River, in the northern part of Southern India. With an average altitude of , much of Hyderabad is situated on hilly terrain around artificial lakes, including the Hussain Sagar lake, predating the city's founding, in the north of the city centre. According to the 2011 Census of India, Hyderabad is the fourth-most populous city in India with a population of residents within the city limits, and has a population of residents in the metropolitan region, making it the sixth-most populous metropolitan area in India. With an output of 74 billion, Hyderabad has the fifth-largest urban economy in India. Muhammad Quli Qutb Shah established Hyderabad in 1591 to extend the capital beyond the fortified Golconda. In 1687, the city was annexed by the Mughals. In 1724, Asaf Jah I, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chung Sang Eo
The K745 Blue Shark (Hangul: 청상어 경어뢰) is a light anti-submarine torpedo developed for the Republic of Korea Navy in 2004. The Blue Shark torpedo can be deployed from surface ships, ASW helicopters and maritime patrol aircraft. Production cost for each torpedo is at about ₩ 1,000,000,000. Blue Shark torpedoes are fitted to the Incheon class frigate (FFX). An improved variant, the lightweight torpedo-2 is being developed by LIG Nex1. New capabilities include longer range and lesser vulnerability to decoys.

Yu-7 Torpedo
The Yu-7 (; from ) is a lightweight torpedo developed by the People's Republic of China. It entered service in the 1990s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships. The Yu-7 is a derivative of the Whitehead Alenia Sistemi Subacquei (WASS) A244/S torpedo. Development Development of an effective lightweight anti-submarine (ASW) torpedo for the PLAN began in the 1980s. The program was probably based on 40 A244/S torpedoes purchased for evaluation from Italy in 1987. Additional technology may have been reverse engineered from a United States Mark 46 Mod 2 torpedo recovered from the South China Sea in 1978 by Chinese fishermen. The torpedo was initially equipped with electric propulsion, but inadequate performance led to a redesign powered by Otto fuel II. Testing was carried out at the 750 Testing Range in Kunming up to 1988. Description The Yu-7 has contrarotating propellers. Aboard surface warships, it is fired from Type 7424 tr ...

Sting Ray (torpedo)
The Sting Ray is a British acoustic homing lightweight torpedo (LWT) manufactured by GEC-Marconi, who were later bought out by BAE Systems. It entered service in 1983. Design and development In the 1950s the Royal Navy was equipped with British designed and built Mk 30 air-dropped torpedoes. These were passive homing weapons which relied on detecting the noise from submarine targets. However, as submarine noise levels decreased these weapons became ineffective. A design for a British Mk 31 torpedo which would have used active echo-location sonar failed to receive Government approval for production. US Mk 44 torpedoes were purchased for the Royal Navy in the 1960s to fill this role, and later replaced by US Mk 46 torpedoes. A desire not to be dependent on US torpedo purchases led to a research programme starting in 1964 to develop a British torpedo. Initially designated Naval and Air Staff Requirement (NASR) 7511, it was (much later in the late 1970s) designated the Sting ...

Mark 54 Lightweight Torpedo
The Mark 54 Lightweight Torpedo (formerly known as Lightweight Hybrid Torpedo, or LHT) is a standard anti-submarine warfare (ASW) torpedo used by the United States Navy. Development The Mark 54 was co-developed by Raytheon Integrated Defense Systems and the U.S. Navy under the U.S. Navy's Lightweight Hybrid Torpedo program in response to perceived problems with the extant Mark 50 and Mark 46 torpedoes. The Mk 50, having been developed to counter very high performance nuclear submarines such as the Soviet Alfa class, was seen as too expensive to use against relatively slow conventional submarines. The older Mk 46, designed for open-ocean use, performed poorly in the littoral areas, where the Navy envisioned itself likely to operate in the future. The Mk 54 was created by combining the homing portion of the Mk 50 and the warhead and propulsion sections of the Mk 46, improved for better performance in shallow water, and with the addition of commercial off-the-shelf (COTS) ...

APR-3E Torpedo
The APR-3E airborne light ASW acoustic homing torpedo is designed by Russian Tactical Missiles Corporation JSC to engage current and future submarines at depth from the surface down to 800 metres at speed of up to 43+ knots, and it is a replacement for earlier APR-2 light antisubmarine acoustic homing torpedo. APR-3E airborne light antisubmarine acoustic homing torpedo is designed to be carried by a various fixed wing and rotary wing platforms including Tu-142, Il-38, Ka-28 and other aircraft. The torpedo requires at least 100 metres depth of water for the initial air-drop and can be deployed in conditions up to sea state 6. Once entering water, the control surfaces of the torpedo enable the torpedo to travel in a spiral path with the help of gravity without starting the engine. During this stage, the acoustic seeker of the torpedo searches for targets. Once the target is identified, the engine starts and solid propellant rocket engine ensures the target has virtually very ...
