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.
The Hedgehog was a forward-throwing anti-submarine weapon that was used primarily during the Second World War. The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U-boat. It was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges.
The Delhi-class destroyers are guided-missile destroyers of the Indian Navy. Three ships of this class are in active service. The Delhi-class vessels were the largest vessels to be built in India at the time of their commissioning. The ships were built by Mazagon Dock Limited (MDL) at a cost of ₹750 crore each.
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines.
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately.
The Panzerfaust 3 is a modern semi-disposable recoilless anti-tank weapon, which was developed between 1978 and 1985 and first entered service with the Bundeswehr in 1987. It was first ordered in 1973 to provide West German infantry with an effective weapon against contemporary Soviet armor, thereby replacing West Germany's aging PzF 44 Light Lanze launchers and the heavy Carl Gustaf 84 mm anti-tank recoilless rifle manufactured in Sweden.
The Brahmaputra-class frigates are guided-missile frigates of the Indian Navy, designed and built in India. They are an enhancement of the Godavari class, with a displacement of 3850 tons and a length of 126 metres (413 ft). Although of similar hull and dimension, internally, the Brahmaputra and Godavari classes have different configurations, armaments and capabilities. 3 ships of this class serve in the Indian Navy.
An acoustic torpedo is a torpedo that aims itself by listening for characteristic sounds of its target or by searching for it using sonar. Acoustic torpedoes are usually designed for medium-range use, and often fired from a submarine.
The G7es (T5) "Zaunkönig" ("wren") was a passive acoustic torpedo employed by German U-boats during World War II. It was called the GNAT by the British.
Anti-submarine mortars are artillery pieces deployed on ships for the purpose of sinking submarines by a direct hit with a small explosive charge. They are often larger versions of the mortar used by infantry and fire a projectile in relatively the same manner. They were created during World War II as a development of the depth charge and work on the same principle.
Popeye is a family of air-to-surface missiles developed and in use by Israel, of which several types have been developed for Israeli and export users. A long-range submarine-launched cruise missile variant of the Popeye Turbo has been speculated as being employed in Israel's submarine-based nuclear forces. The United States operated the Popeye under a different designation according to US naming conventions as the AGM-142 Have Nap.
Anti-submarine warfare is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades.
The People's Liberation Army Navy (PLAN) is the naval branch of the People's Liberation Army (PLA), the armed forces of the People's Republic of China. The PLAN force consists of approximately 250,000 men and over a hundred major combat vessels, organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet.
The Audace-class destroyers were two guided missile destroyers built for the Italian Navy during the Cold War. An improvement of the Impavido class, these ships were designed for area air defence and also had a heavy gun armament. They were fitted with contemporary American radars and sonars, but also, as the next Italian ships, all the modern weapons made by Italian industry of the time, such torpedoes, helicopters and guns. Also some indigenous radars were fitted.
The Parchim-class corvette, Soviet designation Project 1331M, was developed for the East German Navy in the late 1970s, and built by the Wolgast Peene-Werft. The ships were designed for coastal anti-submarine warfare. In case of an all-out NATO-Warsaw Pact war in Europe their prime targets would have been the small U-206 coastal submarines of the West German navy. The first ship, Wismar, was launched on 9 April 1981 in Rostock, and subsequently another 15 ships were built until 1986. To make production more economical, the Soviet Union agreed to purchase another 12 ships from Wolgaster Peenewerft built between 1986 and 1990, thereby effectively subsidising the East German shipbuilding industry.
The Meroka CIWS is a Spanish Navy 12 barrelled 20 mm CIWS, using twelve Oerlikon 20 mm/12 guns mounted in 2 rows of 6 guns each. The system's primary purpose is defence against anti-ship missiles, and other precision guided weapons. However, it can also be employed against aircraft, ships and other small craft, coastal targets, and floating mines. The weapon is mounted primarily on Spanish naval vessels, from frigate size upwards.
Mărășești (F111) is a frigate currently serving with the Romanian Navy. Mărășești served as the flagship of the navy between 1985–2004, when Regele Ferdinand became the new flagship. She is the largest warship of the Romanian Navy ever built in Romania.
The Yu-3 (鱼-3) is a Chinese acoustic homing torpedo designed to be fired from submarines against surface targets. It entered service with the Chinese Navy in 1984. Several sources state that it may be a copy of the Soviet SET-65E, although this seems unlikely as development began in 1965 after the Sino-Soviet split. It is therefore probably the first indigenously developed torpedo in China.
The Mark 21 Mod 2 torpedo, was a passive acoustic homing variant of the Mark 13 torpedo. It used the widely used Mark 13 torpedo as a basis, with the addition of passive acoustic homing developed by Bell Labs.
A nuclear torpedo is a torpedo armed with a nuclear warhead. The idea behind the nuclear warheads in a torpedo was to create a much bigger explosive blast. Later analysis suggested that smaller, more accurate, and faster torpedoes were more efficient and effective.
