Active Radar Seeker
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a passive radar, receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox (code word), fox three. Advantages There are two major advantages to active radar homing: * As the missile is tracking the target it is going to be much closer to the target than the launching platform during the terminal phase, thus the missile's tracking can be much more accurate and better resistant to electronic countermeasures. Active radar homing missiles have some of the best kill probability, kill probabilities, along with missiles employing track-via-missile guidance. * Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, an ...

Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming. There are two general classes of radar jamming, mechanical and electronic. Mechanical jamming entails reflecting enemy radio signals in various ways to provide false or misleading target signals to the radar operator. Electronic jamming works by transmitting additional radio signals towards enemy receivers, making it difficult to detect real target signals, or take advantage of known behaviors of automated systems like radar lock-on to confuse the system. Various counter-countermeasures can sometimes he ...

PL-12
The PL-12 (, NATO reporting name: CH-AA-7) is an active radar-guided beyond-visual-range air-to-air missile developed by the People's Republic of China. It is considered comparable to the US AIM-120 AMRAAM and the Russian R-77. History Development of the PL-12 (SD-10) began in 1997. The first public information of the Leihua Electronic Technology Research Institute's PL-12 then called the SD-10 emerged in 2001. Development was assisted by Vympel NPO and Agat of Russia.Medeiros et al.: page 92 Liang Xiaogeng is believed to have been the chief designer. Four successful test firings were made in 2004. The missile entered People's Liberation Army Air Force (PLAAF) service in 2005. Design The early batches of PL-12 missiles reportedly used the 9B-1348 radar seeker designed for the R-77 missile. The development process was assisted by Vympel NPO and Tactical Missile Corporation and benefited from Russian technology transfers. But as of 2018, the PL-12 was no longer reliant on Russia ...

HN-2000
HN (reported short for Hong Niao, or Hongniao, 红鸟 meaning Red Bird) missiles are a series of turbofan powered Chinese land attack cruise missiles, based on the X-600. Development Although China was satisfied with the performance of its own Changfeng series land attack cruise missile, an inherent problem with this turbojet powered Changfeng (missile) meant that the size and weight of the missile were too large to be carried by aerial platforms in Chinese inventory and the range of the missile was inadequate. A turbofan powered version was needed, but due to the limitation of Chinese R&D and industrial capability of the time, this could not be achieved immediately. As a result, China decided to take a two-step approach, first to have the turbojet powered Changfeng missile meet the immediate need, then complete development on a turbofan powered version like the Tomahawk (missile) for deployment on aerial platforms while China was building up its industrial infrastructure. The ...

DF-26
__NoTOC__ The Dong Feng-26 (DF-26, ) is an intermediate-range ballistic missile deployed by the People's Liberation Army Rocket Force and produced by the China Aerospace Science and Technology Corporation (CASC). Chinese sources claim the DF-26 has a range of over and may conduct precision nuclear or conventional strikes against ground and naval targets. It is China's first conventionally-armed ballistic missile claimed to be capable of reaching Guam and the American military installations located there; this has led to the missile being referred to as the "Guam Express" or "Guam Killer".Wilson: page 4 The possibility that a DF-26 unit could have nuclear warheads makes it likely an adversary would target these missiles in a first strike. The missile was officially revealed at the Chinese 2015 parade commemorating the end of the Second World War. In April 2018, it was officially confirmed that the DF-26 was in service with the People's Liberation Army Rocket Force (PLARF). Th ...

DF-25
DF-25 (Dong Feng-25) was a Chinese two-stage, solid-propellant, road-mobile Intermediate-range ballistic missile (IRBM). Missilethreat.com stated it could deliver a single or multiple conventional warheads weighing over a maximum distance of 3,200 km to 4,000 km. There are conflicting reports on whether the DF-25 entered service, and if so, when. The Federation of American Scientists notes reports that China had abandoned development of the DF-25 in 1996. The U.S. Department of Defense The United States Department of Defense (DoD, USDOD or DOD) is an executive branch department of the federal government charged with coordinating and supervising all agencies and functions of the government directly related to national secur ... in its 2013 report to Congress on China's military developments made no mention of the DF-25 as a missile in service.

DF-21
The Dong-Feng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng () is a two-stage, solid-fuel rocket, single-warhead medium-range ballistic missile (MRBM) in the Dong Feng series developed by China Changfeng Mechanics and Electronics Technology Academy. Development started in the late 1960s and was completed around 1985–86, but it was not deployed until 1991. It was developed from the submarine-launched JL-1 missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers; approximately 10-11 missiles can be built annually. Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. It is thought able to carry a high explosive, submunition, or 300 kt nuclear warhead. The latest DF-21D was said to be the world's first anti-ship ballistic missile (ASBM). The DF-21 has also been developed into a space-capable anti-sate ...

Millimeter Wave Guidance
Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ten to one millimetre, so it is also called the millimetre band and radiation in this band is called millimetre waves, sometimes abbreviated MMW or mmWave. Millimetre-length electromagnetic waves were first investigated by Indian physicist Jagadish Chandra Bose, who generated waves of frequency up to 60GHz during experiments in 18941896. Compared to lower bands, radio waves in this band have high atmospheric attenuation: they are absorbed by the gases in the atmosphere. Absorption increases with frequency until at the top end of the band the waves are attenuated to zero within a few meters. Absorption by humidity in the atmosp ...

Anti-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the ''Fritz X'', including the Italian battleship ''Roma'' and the light cruiser . A variant of the HS 293 had a TV ca ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ...

Datalink
A data link is the means of connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is used to send information between aircraft and air tr ...
