PL-11 (missile)
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. It is a development or copy of the Italian Aspide AAM, which in turn was developed from the American AIM-7 Sparrow. The PRC may have started license production of the Aspide using imported parts but the license was cancelled following the 1989 Tiananmen Square protests. Development started in 1990, and the first live-fire test occurred in 1992 from a Shenyang J-8 IIB. Description The PL-11 was the People's Liberation Army Air Force's main medium-ranged AAM until the PL-12. The HQ-61 is the 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.

Air-to-air Missile
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft (including unmanned aircraft such as cruise missiles). AAMs are typically powered by one or more rocket motors, usually solid-fuel rocket, solid fueled but sometimes liquid-fuel rocket, liquid fueled. Ramjet engines, as used on the Meteor (missile), Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of around 30 km to 40 km maximum are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or LRAAMs), which ...

Shenyang J-8
The Shenyang J-8 (Simplified Chinese characters, Chinese: 歼-8; NATO reporting name: Finback) is a family of interceptor aircraft developed by the Shenyang Aircraft Design Institute, 601 Institute (Shenyang) in the People's Republic of China (PRC). It was conceived in the early 1960s as a low-risk program based on enlarging the Mikoyan-Gurevich MiG-21F, a version of which the PRC was producing as the Chengdu J-7. The original J-8 experienced protracted development due to disruption from the Cultural Revolution; the prototypes first flew in 1969 but the design was not finalized until 1979 with the aircraft entering service in 1980. The J-8II/J-8B (NATO reporting name: Finback-B) was a major development of the J-8 and was essentially a new aircraft. The J-8II replaced the distinctive nose air intake with a conventional radome and side air intakes to create room for a modern fire-control radar, and used more powerful engines. The aircraft started development in 1982, and was clear ... [...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 ...

HQ-61
The HQ-6, also known as LY-60 (NATO reporting name: CH-SA-6), is a family of People's Republic of China, Chinese air defense missiles developed by the Shanghai Academy of Science and Technology, largely based on the Chinese PL-11 (missile), PL-11 and Italian Selenia (company), 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 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.

People's Liberation Army Air Force
The People's Liberation Army Air Force, also referred to as the Chinese Air Force () or the People's Air Force (), is the primary aerial warfare service of the People's Liberation Army. The PLAAF controls most of the PLA's air assets, including tactical aircraft, large airlifters, and strategic bombers. It includes ground-based air defense assets, including national early-warning radars, and controls the People's Liberation Army Air Force Airborne Corps, Airborne Corps. The PLAAF traces its origins to the establishment of a small aviation unit by the Chinese Communist Party (CCP) in 1924, during the early years of the Republic of China. This initial group comprised nine cadets who trained under the Guangzhou Revolutionary Government Aviation Bureau, with further advanced training in the Soviet Union. Despite initial resource constraints, including a lack of aircraft and airfields, the CCP's Central Military Commission (China), Central Military Commission (CMC) established foun ...

1989 Tiananmen Square Protests
The Tiananmen Square protests, known within China as the June Fourth Incident, were student-led Demonstration (people), demonstrations held in Tiananmen Square in Beijing, China, lasting from 15 April to 4 June 1989. After weeks of unsuccessful attempts between the demonstrators and the Chinese government to find a peaceful resolution, the Chinese government People's Liberation Army at the 1989 Tiananmen Square protests and massacre, deployed troops to occupy the square on the night of 3 June in what is referred to as the Tiananmen Square massacre. The events are sometimes called the '89 Democracy Movement, the Tiananmen Square Incident, or the Tiananmen uprising. The protests were precipitated by the Death of Hu Yaobang, death of pro-reform Chinese Communist Party (CCP) General Secretary of the Chinese Communist Party, general secretary Hu Yaobang in April 1989 amid the backdrop of rapid economic development and social change in History of the People's Republic of China (19 ...

High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or Dust explosion, grain dust * pressure, pressurized gas compressor, gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear weapon, nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high ...

AIM-7 Sparrow
The AIM-7 Sparrow (Air Intercept Missile) is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers, and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made it difficult to achieve lock-on at the missile's effective range. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat the enemy fighter would often approach within ...

Aspide
Aspide, named for the asp, is an Italian medium range air-to-air and surface-to-air missile produced by Selenia and its successors, Alenia Aeronautica and MBDA that was developed in the 1970s to replace license built AIM-7 Sparrows then in use on Italian Air Force F-104S Starfighter interceptors. It is similar in appearance to the Sparrow, with original versions sharing an airframe with the type and all using a similar semi-active radar homing seeker. This similarity in appearance combined with Selenia's license production of Sparrows has to lead non-Italian press frequently referring to the missile as a Sparrow variant. Compared to Sparrow, Aspide features an inverse monopulse seeker that is far more accurate and much less susceptible to ECM than the original continuous-wave version. Aspide also features new electronics, a new warhead, and a new, more powerful engine. Closed-loop hydraulics were also substituted for Sparrow's open-loop type, which gave Aspide better downr ...
