Battle of Pacocha

indecisive actionPacocha Incident
There was a last-ditch effort to stop or sink the rebels when two small torpedo rams from Shah attempted to find the Huáscar, but the Peruvian ship managed to escape under the cover of darkness. The rebel crew was forced to surrender their ship to the Peruvian government just two days later. This battle saw the first use of the newly invented self-propelled torpedo which, at the time, had just entered limited service with the Royal Navy. The torpedo was dodged by the rebel monitor. * Specifics of the Incident

Battle off Samar

Taffy 3SamarTaffy 2
The shell could not pierce the hull armor, but the 7 lb bursting charge that it contained may have set off the eight deck-mounted Japanese Type 93 "Long Lance" torpedoes, which were especially volatile because they contained pure oxygen, in addition to their 1080 lb warheads. The explosion resulted in such severe damage that it knocked out the rudder and engines, causing Chōkai to drop out of formation. Within minutes, an American aircraft dropped a 500 lb bomb on her forward machinery room. Fires began to rage and she went dead in the water. Later that day, she was scuttled by torpedoes from the destroyer.

Wake homing

Wake homing is a technique used to guide torpedoes to their target. The torpedo is fired to cross behind the stern of the target ship through the wake, as it does so it uses sonar to look for changes in the water caused by the passage of the ship, such as the small air bubbles. When these are detected the torpedo turns toward the ship then follows a zig-zag course, turning when it detects the outer edge of the wake, to keep itself in the wake. This will eventually bring it to the rear of the ship, where its warhead can do the most damage to propulsion and steering. The system is difficult to jam, though can be distracted by other ships crossing the wake.

Yono-class submarine

Yono class submarine2-men midget submarinemidget submarine
A Yono-class submarine is thought to have fired the torpedo attack which sank a South Korean, on 26 March 2010 in South Korean waters. According to some investigators, the weapon used in the attack was a North Korean-manufactured CHT-02D torpedo, from which substantial propulsion parts were recovered. The device allegedly exploded not by contact, but by proximity 6 to 9 m below Cheonan, creating a powerful pillar of water, called the bubble jet effect. High ranking North Korean military officials denounced the international investigation and said the North does not have the type of submarines that supposedly carried out the attack.

ROKS Cheonan sinking

ROKS ''Cheonan'' sinkingsinkingROKS ''Cheonan
To back up their claims, the Chinese said that North Korean submarines such as the one believed to have sunk Cheonan were incapable of moving undetected within South Korean waters, and a rising mine would have damaged the ship by splitting the hull, as was done to Cheonan, rather than simply holing the vessel as a conventional torpedo does. A conventional torpedo traveling at 40 – would also be completely destroyed upon impact, which was claimed to contradict the torpedo parts found later. (The original report, however, did not assert that a conventional torpedo strike had occurred, but rather that the torpedo had exploded underneath the ship, thus breaking its back.

Falklands War

The Lynx launched a torpedo, and strafed the submarine with its pintle-mounted general purpose machine gun; the Wessex also fired on Santa Fe with its GPMG. The Wasp from as well as two other Wasps launched from fired AS-12 ASM antiship missiles at the submarine, scoring hits. Santa Fe was damaged badly enough to prevent her from diving. The crew abandoned the submarine at the jetty at King Edward Point on South Georgia. With Tidespring now far out to sea, and the Argentine forces augmented by the submarine's crew, Major Sheridan decided to gather the 76 men he had and make a direct assault that day.

Aerial torpedo

torpedoair-launched torpedoair-dropped torpedo
General Billy Mitchell suggested arming the torpedo bombers with live warheads as part of Project B (the anti-ship bombing demonstration) but the Navy was only curious about aerial bomb damage effects. Instead, a trial using dummy heads on the torpedoes was carried out against a foursome of battleships steaming at 17 knots. The torpedo bombers scored well. In 1931, the Japanese Navy developed the Type 91 torpedo, intended for a torpedo bomber to drop from a height of 330 ft and a speed of 100 kn. In 1936, the torpedo was given wooden attachments to the tail, nicknamed the Kyoban, to increase its aerodynamic qualities—these attachments were shed upon hitting the water.

The name is short for torpedo explosive, having been originally developed for use in torpedoes. Torpex proved to be particularly useful in underwater munitions because the aluminium component had the effect of making the explosive pulse last longer, which increased the destructive power. Torpex was used only in critical applications, e.g. torpedoes, depth charges, and the Upkeep, Tallboy, and Grand Slam bombs. It was also used in the Operation Aphrodite drones. Torpex has long been superseded by H6 and PBX compositions. It is therefore regarded as obsolete, so Torpex is unlikely to be encountered except in old munitions or unexploded ordnance.

MU90 Impact

MU90Eurotorp MU90MU 90
It uses a shaped charge warhead that can penetrate any known submarine hull, in particular Soviet double hull designs, while remaining just as deadly in shallow waters where conventional warheads are less effective. In 1986 France and Italy began a collaboration to develop an anti-submarine missile based on the Italian Otomat missile. France dropped out of the programme but Italy has fitted the MBDA MILAS missile to its s and FREMM anti-submarine frigates. MILAS is a 800 kg missile that can deliver a MU90 to 35 km.

Acoustic signature

Modern naval mines and torpedoes such as the CAPTOR mine can be programmed to distinguish the acoustic signatures of different vessels, leaving friendly vessels unmolested and attacking high-value targets when faced with multiple possible targets, e.g. distinguishing an aircraft carrier from its escorts. Warship designers aim to reduce the acoustic signature of ships and submarines just as much as they aim to reduce the radar cross sections and infra-red signals. For submarines, as a prime factor in how they can be detected the reduction of the acoustic signature is a primary goal.

Torpedo tube

torpedo tubestubetubes
A torpedo tube is a cylinder shaped device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles.

G7e torpedo

G7eG7e/T4 FalkeG7e/T2 torpedo
The T4 was not an ordinary straight-running torpedo, it ran at 20 kt (37 km/h) for 7500 m and it might, depending on the exact date, have been the world's first acoustic homing torpedo in Naval service, since it was introduced in March 1943, the same month and year as the American Mk-24 "Mine" acoustic homing torpedo. Early in 1933 Germany started development and testing of acoustic homing mechanisms for torpedoes. From the outset of submarine warfare, submariners had dreamed of being able to aim and fire torpedoes without surfacing or using a periscope.

G7a torpedo

The G7a (TI) torpedo was 533.4 mm (21 in) in diameter, 7163 mm (23 ft 6 in) in length (with a type Ka or Kb warhead and Pi1 or Pi2 pistol), the warhead holding a charge of approximately 280 kg (617lbs) of so-called Schießwolle 36. It was Kriegsmarine's first operational torpedo (hence "TI" = Torpedo number one), and the standard issue torpedo for all German U-boats and surface torpedo-bearing vessels from ca 1935 to the end of WW2. The torpedo was of a straight-running unguided design, controlled by a gyroscope. The TI was of variable speed, running a distance of 5,000 m at 81 km/h (5,500 yd at 44kt), 7,500 m at 74 km/h (8,250 yd at 40 kt), and 12,000 m at 55.6 km/h (13,200 yd at 30 kt).

Mark 48 torpedo

Mk48 ADCAP torpedoMark 48Mk-48 torpedoes
This may refer to the electromagnetic coils on the warhead (at least from 1977 to 1981), used to sense the metallic mass of the ship's hull and detonate at the proper stand-off distance. The torpedo has been the subject of continued improvement over its service lifetime. In the 1990s, a Mod 6 variant of the ADCAP provided much improved noise isolation for the engine, which makes this torpedo more difficult to detect for a potential target. The Mk48 Mod 7 Common Broadband Advanced Sonar System (CBASS) torpedo is optimized for both the deep and littoral waters and has advanced counter-countermeasure capabilities.

Type 95 torpedo

Type 95Type 95 oxygen-propelled torpedoes
The Type 95 torpedo was a torpedo used by submarines of the Imperial Japanese Navy during World War II. It was based on the Type 93 torpedo (Long Lance ) but mod 1 had a smaller 405 kg and mod 2 had a larger 550 kg warhead, shorter range and a smaller diameter. It was intended to be fired from a standard 533 mm torpedo tube of a submerged submarine. Its range was (for the mod 1) 9000 m at, or 12000 m at 45 - 47 kn, which was about three times the range of the American Mark 14 at the same speed. The Type 95 was the fastest torpedo in common use by any navy at the time. Its warhead size was the largest of any submarine torpedo, and second only to the Type 93 used by Japanese surface ships.

Battle of Jutland

JutlandJutland 1916The Battle of Jutland
All ships, not just the destroyers armed principally with torpedoes but also battleships, were reminded that they carried torpedoes intended to be used whenever an opportunity arose. Destroyers were instructed to close the enemy fleet to fire torpedoes as soon as engagements between the main ships on either side would keep enemy guns busy directed at larger targets. Destroyers should also be ready to immediately engage enemy destroyers if they should launch an attack, endeavouring to disrupt their chances of launching torpedoes and keep them away from the main fleet.
