Tariq-class Destroyer
The ''Tariq''-class destroyers are a class of guided missile destroyers of the Pakistan Navy. They were acquired from the British Royal Navy in 1993–94. The ''Tariq''s were formerly commissioned in the Royal Navy's Surface Fleet as Type 21 (''Amazon''-class) frigates, a general purpose frigate in the Royal Navy. The British frigates were immediately acquired when the United States refused to renew the lease of the four and four s, due to the enforcement of the Pressler Amendment. requiring Pakistan to return the vessels to the United States at the end of their five-year lease. Upon acquisition, all six frigates were reconfigured to enhance their engineering design and construction and military software updates that feature Swedish technology, giving them missile launching capability. Following these upgrades, the ships were reclassified as destroyers. In 2008, the Pakistan Navy had carried out a successful test of the Camcopter S-100, an unmanned aerial vehicle, from t ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided Missile Destroyer
A guided-missile destroyer (DDG) is a destroyer whose primary armament is guided missiles so they can provide anti-aircraft warfare screening for the fleet. The NATO standard designation for these vessels is DDG, while destroyers who have a primary gun armament and/or a small number of anti-aircraft missiles sufficient only for point-defense are designated DD. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. Guided-missile destroyers are equipped with large missile magazines, with modern examples typically having vertical-launch cells. Some guided-missile destroyers contain integrated weapons systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true for navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap. Many guided-missile destroyers are also multipurpo ...

Ship Class
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. s' names all begin with T (, , ); and s are named after American battles (, , , ). Ships of the same class may be referred to as sister ships. Naval ship class naming conventions Overview The name of a naval ship class is most commonly the name of the lead ship, the first ship commissioned or built of its design. ...

Flight Deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese Akagi and battleship Kaga, were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner . The armoured flight deck was another innovation pioneered by the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Westland Lynx
The Westland Lynx is a British multi-purpose twin-engined military helicopter designed and built by Westland Helicopters at its factory in Yeovil. Originally intended as a utility craft for both civil and naval usage, military interest led to the development of both battlefield and naval variants. The Lynx went into operational usage in 1977 and was later adopted by the armed forces of over a dozen nations, primarily serving in the battlefield utility, anti-armour, search and rescue and anti-submarine warfare roles. The Lynx is a fully aerobatic helicopter with the ability to perform loops and rolls. In 1986, a specially modified Lynx set the current Fédération Aéronautique Internationale's official airspeed record for helicopters (category excludes compound helicopters) at , which remains unbroken as of January 2022.

LY-60 / FD-60 / PL10
The HQ-6, also known as LY-60, is a family of Chinese air defense missiles developed by the Shanghai Academy of Science and Technology, largely based on the Chinese PL-11 and Italian Selenia (now as Leonardo S.p.A.) Aspide missile. Development HQ-6 is a surface-to-air missile system developed by the Shanghai Academy of Science and Technology, incorporating technologies from PL-11 missile. PL-11 is the license-produced version of Aspide missile, which itself is based on the American AIM-7 Sparrow missile. It was speculated the missile is a copy of AIM-7 when the system was revealed in the late 1970s, though HQ-6 is considerably larger than the AIM-7 Sparrow. HQ-6 missile went through multiple iterations, and an export variant named LY-60 was also developed. Variants PL-11 The PL-11 () is a medium-range semi-active radar homing (SARH) air-to-air missile (AAM) developed by a subsidiary of the Shanghai Academy of Spaceflight Technology in the People's Republic of China.

Harpoon (missile)
The Harpoon is an all-weather, over-the-horizon, anti-ship missile manufactured by McDonnell Douglas (now Boeing Defense, Space & Security). The AGM-84E Standoff Land Attack Missile (SLAM) and later AGM-84H/K SLAM-ER (Standoff Land Attack Missile – Expanded Response) are cruise missile variants. The regular Harpoon uses active radar homing and flies just above the water to evade defenses. The missile can be launched from: * Fixed-wing aircraft (AGM-84), without the solid-fuel rocket booster) * Surface ships (RGM-84), fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile's main turbojet to maintain flight) * Submarines (UGM-84), fitted with a solid-fuel rocket booster and encapsulated in a container to enable submerged launch through a torpedo tube); * Coastal defense batteries (RGM-84), from which it would be fired with a solid-fuel rocket booster. Development In 1965, the United States Navy began studies for a missile in the range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
