HQ-9
The HQ-9 ( zh, s=红旗-9, t=紅旗-9, p=Hóng Qí-9, l=Red Banner-9; NATO reporting name: CH-SA-9.) is a long-range semi-active radar homing (SARH) surface-to-air missile (SAM) developed by the People's Republic of China. The naval variant is the HHQ-9 ( zh, s=海红旗-9, t=海紅旗-9, p=Hǎi Hóng Qí-9, l=Sea Red Banner-9). Description The HQ-9 is a derivative of the Russian S-300. Justin Bronk of the Royal United Services Institute describes the missile as a "hybrid design based on the Russian SA-20 but with radar, seeker head and C2 elements heavily influenced by American and Israeli technology." The missile uses track-via-missile (TVM) guidance combining inertial guidance, mid-course uplink, and terminal active radar. The TVM used on earlier missiles may have been developed from a United States MIM-104 Patriot missile purchased from Israel or Germany. According to a 2001 article from ''Defence International'', the HQ-9 is 6.8 m. long with a mass of nearly two tons. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased-array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased-array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-ballistic Missile
An anti-ballistic missile (ABM) is a surface-to-air missile designed to Missile defense, destroy in-flight ballistic missiles. They achieve this explosively (chemical or nuclear), or via hit-to-kill Kinetic projectile, kinetic vehicles, which may also have self-maneuvering. Tactical systems are widely deployed to counter Short-range ballistic missile, short and Intermediate-range ballistic missile, intermediate-range ballistic missiles that carry conventional weapon, conventional warheads. Strategic systems, deployed by the United States, Russia, and Israel, are capable of intercepting intercontinental ballistic missiles, typically used to carry Strategic nuclear weapon, strategic nuclear warheads. During the Cold War, the 1972 ABM Treaty limited the nuclear arms race; excessive ICBM production would have been favoured to overwhelm ABM systems. Of the modern strategic ABM systems, only Russia's are themselves armed with nuclear warheads. Current counter-ICBM systems There are ...

HQ-19
The HQ-19 (, NATO reporting name: CH-AB-2) is an anti-ballistic missile (ABM) and anti-satellite weapon (ASAT) system developed by the People's Republic of China. It's a variant of the HQ-9 long-range surface-to-air missile system. The HQ-19 system is designed to counter medium-range ballistic missiles. It targets ballistic missiles in their midcourse and terminal phases, comparable to the US THAAD. The missile may have "begun preliminary operations" by 2018. History On 6 June 2025, Pakistan announced plans to acquire the HQ-19. Development and design The HQ-19 was developed under the 863 Program, initiated in the late 1990s. The missile was successfully tested in 1999, with multiple reports confirming its capability to hit targets at an altitude of and speed of . Several more tests were conducted in the 2010s, with the Chinese Ministry of National Defense certificated the missile capabilities in 2021.

S-300 Missile System
The S-300 (NATO reporting name SA-10 Grumble) is a series of long-range surface-to-air missile systems developed by the former Soviet Union. It was produced by NPO Almaz for the Soviet Air Defence Forces to defend against air raids and cruise missiles. It is used by Russia, Ukraine, and other former Eastern Bloc countries, along with Bulgaria and Greece. It is also used by China, Iran, and other countries in Asia. The system is fully automated, though manual observation and operation are also possible. Each targeting radar provides target designation for the central command post. The command post compares the data received from the targeting radars and filters out false targets. The central command post has both active and passive target detection modes. Missiles have a maximum range of from the command post. The successor to the S-300 is the S-400 (NATO reporting name ''SA-21 Growler''), which entered service on 28 April 2007. Variations and upgrades There are current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track-via-missile
Track-via-missile or TVM refers to a missile guidance technique which combines features of semi-active radar homing (SARH) and radio command guidance. This avoids the problems with terminal accuracy normally seen by command guided missiles, especially at long range. It has been used on a number of long-range surface-to-air missiles (SAMs) including the MIM-104 Patriot. Explanation Command guidance has the advantage of isolating most of the equipment for the missile guidance at the launcher, where size and weight are significantly less important. In these systems, the radar that provides guidance is on the ground or ship and the missile lacks an independent guidance system. Typically two radars are used, one tracking the target and another the missile, so that they can fly independent and widely separated paths. A computer then calculates the position and velocity of the two and calculates an intercept point. The same computer then calculates the control inputs needed to fly the m ...

MIM-104 Patriot
The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the "Phased Array Tracking Radar to Intercept on Target", which is a backronym for "Patriot". In 1984, the Patriot system began to replace the Nike Hercules system as the U.S. Army's primary high to medium air defense (HIMAD) system and the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to these roles, Patriot has been given a function in the U.S. Army's anti-ballistic missile (ABM) system. , the system is expected to stay fielded until at least 2040. Patriot uses an advanced aerial interceptor missile and high-performance radar systems. Patriot was developed at Redstone Arsenal in Huntsville, A ...

Stealth Aircraft
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology. Other examples of stealth aircraft include the Northrop Grumman B-2 Spirit, B-2 Spirit, the B-21 Raider, the Lockheed Martin F-22 Raptor, F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is completely invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft avoiding detection by enemy radar and/or avoiding being successfully targeted by Semi-active radar guidance, radar guided weapons. Stealth is a combination of passive low observable (LO) features and active emitters such as low-probability-of-interc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Radar
Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of ''bistatic radar'' – passive bistatic radar (PBR) – which is a broad type also including the exploitation of cooperative and non-cooperative radar transmitters. Introduction Conventional radar systems comprise a colocated transmitter and receiver (radio), receiver, which usually share a common antenna (radio), antenna to transmit and receive. A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the object to be determined. In a passive radar system, there is no dedicated transmitter. Instead, the receiver uses third-party transmitters in the environment and m ...

Terminal High Altitude Area Defense
Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American anti-ballistic missile defense system designed to intercept and destroy short-, medium-, and intermediate-range ballistic missiles in their terminal phase (descent or reentry). The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile. THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991. Originally a United States Army program, THAAD has come under the umbrella of the Missile Defense Agency. The Navy has a similar program, the sea-based Aegis Ballistic Missile Defense System, which also has a land component ("Aegis Ashore"). THAAD was originally scheduled for deployment in 2012, but initial deployment took place in May 2008. THAAD has been deployed in the United Arab Emirates (UAE), Israel, Romania, and South Korea. On 17 January 2022, THAAD made its first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
