Aspide SAM
Aspide, named for the Vipera aspis, asp, is an Italian medium range air-to-air missile, air-to-air and surface-to-air missile produced by Selenia (company), Selenia and its successors, Alenia Aeronautica and MBDA that was developed in the 1970s to replace license built AIM-7 Sparrow, AIM-7 Sparrows then in use on Italian Air Force Aeritalia F-104S Starfighter, 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 Electronic countermeasures, ECM than the original Continuous-wave radar, continuous-wave version. Aspide also features new electronics, a new warhea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Misil Aspide
Mishil (c. 546/548 – c. 612) was a Silla aristocrat whose historical existence is debatable. According to the ''Hwarang Segi'', she was a concubine to several kings and, along with her aunt Queen Sado, played an instrumental role in dethroning Jinji of Silla, King Jinji. However, it has been questioned whether Misil was truly a historical figure, as she is only mentioned in the Hwarang Segi, and not in the historical texts Samguk Sagi or Samguk Yusa. Biography According to the ''Hwarang Segi'', Mishil was the daughter of Lord Mijinbu and Lady Myodo, a sister of Queen Sado, the consort of Jinheung of Silla. Her paternal grandmother was Princess Samyeop, daughter of Beopheung of Silla, King Beopheung. Due to her lineage, Mishil was a member of the (), or the noble Bone-rank system#Rank, true bone caste. Matrilineally, she belonged to the Matrilineal clan of Daewon Shintong () or directly translated as the divine succession of the great prime. The Daewon Shintong is believed to b ...

Continuous-wave Radar
Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing it to be detected by filtering out the transmitted frequency. Doppler-analysis of radar returns can allow the filtering out of slow or non-moving objects, thus offering immunity to interference from large stationary objects and slow-moving clutter. This makes it particularly useful for looking for objects against a background reflector, for instance, allowing a high-flying aircraft to look for aircraft flying at low altitudes against the background of the surface. Because the very strong reflection off the surface can be filtered out, the much smaller reflection from a target can still be seen. CW radar systems are used at both ends of the ran ...

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.

HQ-6
The HQ-6, also known as LY-60 (NATO reporting name: CH-SA-6), 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.

1989 Tiananmen Square Protests And Massacre
The Tiananmen Square protests, known within China as the June Fourth Incident, were student-led 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 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 pro-reform Chinese Communist Party (CCP) general secretary Hu Yaobang in April 1989 amid the backdrop of rapid economic development and social change in post-Mao China, reflecting anxieties among the people and political elite about the country's future. The reforms of the 1980s had led to a nascent market economy that benefited some people but seriously disadv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Economic Community
The European Economic Community (EEC) was a regional organisation created by the Treaty of Rome of 1957,Today the largely rewritten treaty continues in force as the ''Treaty on the functioning of the European Union'', as renamed by the Lisbon Treaty. aiming to foster economic integration among its member states. It was subsequently renamed the European Community (EC) upon becoming integrated into the Three pillars of the European Union, first pillar of the newly formed European Union (EU) in 1993. In the popular language, the singular ''European Community'' was sometimes inaccurately used in the wider sense of the plural ''European Communities'', in spite of the latter designation covering all the three constituent entities of the first pillar. The EEC was also known as the European Common Market (ECM) in the English-speaking countries, and sometimes referred to as the European Community even before it was officially renamed as such in 1993. In 2009, the EC formally ceased to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-7 Sea Sparrow
The RIM-7 Sea Sparrow is a U.S. ship-borne short-range Surface-to-air missile, anti-aircraft and anti-missile weapon system, primarily intended for defense against anti-ship missiles. The system was developed in the early 1960s from the AIM-7 Sparrow air-to-air missile as a lightweight "point-defense" weapon that could be retrofitted to existing ships as quickly as possible, often in place of existing gun-based anti-aircraft weapons. In this incarnation, it was a very simple system guided by a manually aimed radar illuminator. After its introduction, the system underwent significant development into an automated system similar to other US Navy missiles like the RIM-2 Terrier. Contemporary improvements being made to the Sparrow for the air-to-air role led to similar improvements in the Sea Sparrow through the 1970s and 80s. After that point the air-to-air role passed to the AIM-120 AMRAAM and the Sea Sparrow underwent a series of upgrades strictly for the naval role. It now resembl ...
