F-22P Zulfiquar-class Frigate
The ''Zulfiqar''-class frigate (), also known as F-22P or in English: ''Sword'' class, is a class of multi-mission guided missile frigates, in service with the Pakistan Navy. The class is based on an updated model of the Chinese design, the Type 053H3. The frigates were designed and built jointly in Hudong–Zhonghua Shipbuilding in China and the KS&EW Ltd. in Pakistan. The frigates perform missions including air defense, enemy interdiction, extraction and patrolling the economic exclusive zone (EEZ). History Negotiation, procurement, and development After the return of the and s in 1994, Pakistan entered in negotiation with China to jointly built and design the class of four frigates in 1996–1999. Initial interests were directed towards procuring the Type 053 and Type 054 frigates in 2004, eventually signing a bilateral agreement with China to design the frigates influenced from both designs at the initial price of $600 million USD with the conclusion of the technolo ...

Port Klang
Port Klang () is the principal port of Malaysia on the Strait of Malacca. Known during colonial times as Port Swettenham (), it was renamed to Port Klang in July 1972 and has since become the largest port in the country. It is located about southwest of the town of Klang, Malaysia, Klang, and southwest of Kuala Lumpur. Port Klang was also known as the "National Load Centre". Located in the District of Klang, it was the List of world's busiest container ports, 14th busiest container port (2022) in the world. It was also the 12th busiest port in by volume (million TEU) in 2018 and was the top location for aluminium stockholding for London Metal Exchange, LME, the top metal exchange in the world. History Klang was formerly the terminus of the government railway and the port of the State. In 1880, the state capital of Selangor was moved from Klang to the more strategically advantageous Kuala Lumpur. Rapid development at the new administrative centre in the late 1800s attracted b ...

CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Example ...

Anti-submarine Missile
An anti-submarine missile is a standoff missile, standoff anti-submarine weapon, often a specialized variant of anti-ship missile. Anti-submarine missiles usually include a jet engine, jet or rocket engine, rocket engine and a warhead aimed directly at a submarine. In these missiles, a torpedo or a depth charge is used as a warhead. The anti-submarine missile can be either a cruise missile or a ballistic missile. History Depth charges were the earliest weapons designed for use by ships against submerged submarines. These explosives were initially dropped as the ship moved over the presumed location of a submarine. Before World War II, shipboard sonar was unable to maintain contact with a submarine at close range. Various mortar (weapon), mortar-type projectors, including hedgehog (weapon), Hedgehog and squid (weapon), Squid, were devised during World War II to allow a ship to maintain sonar contact while lobbing explosive charges toward the submarine. During the Cold War, ... [...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, 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 somet ...

Surface-to-surface Missile
A surface-to-surface missile (SSM) is a missile designed to be launched from the ground or the sea and strike targets on land or at sea. They may be fired from hand-held or vehicle mounted devices, from fixed installations, or from a ship. They are often powered by a rocket engine or sometimes fired by an explosive charge, since the launching platform is typically stationary or moving slowly. They usually have fins and/or wings for lift and stability, although hyper-velocity or short-ranged missiles may use body lift or fly a ballistic trajectory. The first operational surface-to-surface missile was the V-1 flying bomb, it was powered by a pulsejet engine. Contemporary surface-to-surface missiles are usually guided. An unguided surface-to-surface missile is usually referred to as a rocket (for example, an RPG-7 or M72 LAW is an anti-tank rocket), whereas a BGM-71 TOW or AT-2 Swatter is an anti-tank guided missile. Examples of surface-to-surface missile include the MGM-140 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. T ...

AK–176
The AK-176 is a Soviet 76mm naval gun mounted in an enclosed turret, that may be used against sea, coastal, and aerial targets, including low flying anti-ship missiles. The system is designed to arm small displacement ships and comprises the Gun Mount with a MR-123-02/76 Fire Control Radar System. It has high survivability owing to autonomous use of the gun mount controlled from the optical sight in the absence of control from the radar system, as well as a capability for fire even if power supply is lost. Design The gun is fed by 152 ready to fire rounds and has selectable rates of fire of 30, 60 and 120 rounds per minute. The 120 r.p.m. rate is achieved by firing a burst of 75, but afterwards the gun has to cool off for 30 minutes. The AK-176 is effective against missiles, being able to shoot down AT-2 Swatter (simulating a Harpoon anti-ship missile), taking an average of 25 rounds per kill. In the late 1980s an upgraded version the AK-176M, with a new fire control system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaff (radar Countermeasure)
Chaff, originally called Window or Düppel, is a Radar jamming and deception, radar countermeasure involving the dispersal of thin strips of aluminium, Metallizing, metallized glass fiber, or Metallised film, plastic. Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. Modern military forces use chaff to distract Active radar homing, active radar homing missiles from their targets. Military aircraft and warships can be equipped with chaff dispensing systems for self-defense. During its Ballistic missile flight phases#Midcourse, midcourse phase, an intercontinental ballistic missile may release chaff along with its other Penetration aid, penetration aids. Contemporary radar systems can distinguish chaff from legitimate targets by measuring the Doppler shift, Doppler effect; chaff quickly loses speed after leaving an aircraft, and the resulting shift in wavelength of the radar return can be measured. To counter this, a chaff cloud can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decoy Flare
A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust. The aim is to make the infrared-guided missile seek out the heat signature from the flare rather than the aircraft's engines. Tactics In contrast to radar-guided missiles, IR-guided missiles are very difficult to find as they approach aircraft. They do not emit detectable radar, and they are generally fired from behind, directly toward the engines. In most cases, pilots have to rely on their wingmen to spot the missile's smoke trail and alert of a launch. Since IR-guided missiles have a shorter range than their radar-guided counterparts, good situational awareness of altitude and potential threats continues to be an effective defense. Mo ...
