AA-2 Atoll
The Vympel K-13 (NATO reporting name: AA-2 "Atoll") is a short-range, infrared homing air-to-air missile developed by the Soviet Union. The K-13 is a reverse engineered copy of the American AIM-9 Sidewinder, hence the similar appearance. Although it since has been replaced by more modern missiles in front-line service, it saw widespread service in many nations. Background During the Second Taiwan Strait Crisis in 1958, Taiwan's F-86 Sabres faced the much higher performance mainland Chinese PLAAF MiG-17s. The MiG-17s had speed, maneuverability, and altitude advantages over the Sabres, allowing them to engage only when they desired, normally at advantageous times. In response, the US Navy rushed to modify 100 ROCAF Sabres to carry the newly introduced AIM-9 Sidewinder missile. These were introduced into combat on 24 September 1958, when a group of MiG-17s cruised past a flight of Sabres, only for them to be attacked by missiles. This was the first instance of guided missiles being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Homing
Infrared homing is a Missile guidance#Passive homing, passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cueing system. Heat-seekers are extremely effective: 90% of all timeline of United States military operations, United States air combat losses between 1984 and 2009 were caused by infrared-homing missiles. They are, however, subject ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Warsaw Pact
The Warsaw Pact (WP), formally the Treaty of Friendship, Co-operation and Mutual Assistance (TFCMA), was a Collective security#Collective defense, collective defense treaty signed in Warsaw, Polish People's Republic, Poland, between the Soviet Union and seven other Eastern Bloc List of non-communist socialist states, socialist republics in Central and Eastern Europe in May 1955, during the Cold War. The term "Warsaw Pact" commonly refers to both the treaty itself and its resultant military alliance, the Warsaw Pact OrganisationPage 22, �NATO and OSCE, Partners or Rivals?��, Edward Killham (WPO) (also known as ‘Warsaw Treaty Organization’ (‘WTO’)). The Warsaw Pact was the military complement to the Comecon, Council for Mutual Economic Assistance (Comecon), the economic organization for the Eastern Bloc states. Dominated by the Soviet Union, the Warsaw Pact was established as a balance of power or counterweight to the NATO, North Atlantic Treaty Organization (NATO) and ...

Kaliningrad K-5
The Kaliningrad K-5 (NATO reporting name AA-1 ''Alkali''), also known as RS-1U or product ShM, was an early Soviet air-to-air missile. History The development of the K-5 began in 1951. The first test firings were in 1953. It was tested (but not operationally carried) by the Yakovlev Yak-25. The weapon entered service as the Grushin/Tomashevich () RS-2U (also known as the R-5MS or K-5MS) in 1957. The initial version was matched to the RP-2U (Izumrud-2) radar used on the MiG-17PFU, MiG-19PM. An improved variant, K-5M or RS-2US in PVO service, entered production in 1959, matched to the RP-9/RP-9U (Sapfir) radar of the Sukhoi Su-9. The People's Republic of China developed a copy under the designation PL-1, for use by their J-6B fighters. The difficulties associated with beam-riding guidance, particularly in a single-seat fighter aircraft, were substantial, making the 'Alkali' primarily a short-range anti-bomber missile. Around 1967 the K-5 was replaced by the K-55 (R-55 in servi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All-aspect
An all-aspect air-to-air missile can track a target no matter which way the target faces relative to the missile. In other words, an all-aspect missile can be launched against a target not only in a tail-chase engagement, but also in a head-on engagement, in a side-on engagement, from above, from below, etc. This is opposed to older infrared homing rear aspect missiles which were only able to track the hot engine exhaust of an aircraft if the aircraft's engine exhaust was pointing towards the missile seeker, and thus were only successfully used in tail-chase engagements. Examples include the US AIM-9 Sidewinder (AIM-9L and later), the Russian Vympel R-73 and the Israeli Rafael Advanced Defense Systems Rafael Advanced Defense Systems Ltd.

Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity Fuse
A Proximity Fuse (also VT fuse or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuses are designed for elusive military targets such as aircraft and missiles, as well as ships at sea and ground forces. This sophisticated trigger mechanism may increase lethality by 5 to 10 times compared to the common contact fuse or timed fuse. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch, or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching the target or after passing it. At the start of the Bl ...

F-8 Crusader
The Vought F-8 Crusader (originally F8U) is a single-engine, supersonic, carrier-based air superiority jet aircraft designed and produced by the American aircraft manufacturer Vought. It was the last American fighter that had guns as the primary weapon, earning it the title "The Last of the Gunfighters". Tillman 1990, .Weaver 2018, p. 63. Development of the F-8 commenced after release of the requirement for a new fighter by the United States Navy in September 1952. Vought's design team, led by John Russell Clark, produced the ''V-383'', a relatively unorthodox fighter that possessed an innovative high-mounted variable-incidence wing, an area-ruled fuselage, all-moving stabilators, dog-tooth notching at the wing folds for improved yaw stability, and liberal use of titanium throughout the airframe. During June 1953, Vought received an initial order to produce three ''XF8U-1'' prototypes of its design. On 25 March 1955, the first prototype performed its maiden flight. Flight t ...

Semi-active Radar Homing
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external source via radar illumination—as it reflects off the target (in contrast to active radar homing, which uses an active radar transceiver). Semi-active missile systems use bistatic continuous-wave radar. The NATO brevity code for a semi-active radar homing missile launch is Fox One. Concept The basic concept of SARH is that since almost all detection and tracking systems consist of a radar system, duplicating this hardware on the missile itself is redundant. The weight of a transmitter reduces the range of any flying object, so passive systems have greater reach. In addition, the resolution of a radar is strongly related to the physical size of the antenna, and in the small nose cone ...
