Cheolmae-2
The KM-SAM ( ko, 천궁 "Cheongung", Hanja: 天弓) which is also known as the Cheolmae-2 is a South Korean medium range surface-to-air missile (SAM) system that was developed by the Agency for Defense Development (ADD) with technical support from Almaz-Antey and Fakel, based on technology from the 9M96 missile used on S-350E and S-400 missile systems. Design and development A complete battery consists of four to six 8-cell transporter erector launchers (TELs), a passive electronically scanned array (PESA) X-band multi-function phased array 3D radar (based on the one from the Russian S-400), and a fire command vehicle. The radar operates in the X-band and rotates at a rate of 40 rpm, covering up to 80 degrees in elevation. It can detect targets within and track up to 40 simultaneously. The KM-SAM is the middle-tier of South Korea's three-tier aerial and missile defense system. Though it was developed in Russia by the Almaz Design Bureau with assistance from Samsung Thale ...

S-400 Missile System
The S-400 Triumf (russian: link=no, C-400 Триумф – Triumf; translation: Triumph; NATO reporting name: SA-21 Growler), previously known as the S-300 PMU-3, is a mobile, surface-to-air missile (SAM) system developed in the 1990s by Russia's NPO Almaz as an upgrade to the S-300 (missile), S-300 family. The S-400 went into service on 28 April 2007. The first battalion of the newest surface-to-air missile systems assumed combat duty on 6 August. Development The development of the S-400 system began in the late 1980s and was announced by the Russian Air Force in January 1993. On 12 February 1999 successful tests were reported at Kapustin Yar in Astrakhan, and the S-400 was scheduled for deployment by the Russian army in 2001. Dr. Alexander Lemanskiy of Almaz-Antey was the Chief Engineer on the S-400 project. In 2003, it became apparent that the system was not ready for deployment. In August, two high-ranking military officials expressed concern that the S-400 was being t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

X-band Radar
The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is rather indefinitely set at approximately 7.0–11.2 GHz. In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (IEEE) as 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks. Radar X band is used in radar applications including continuous-wave, pulsed, single- polarization, dual-polarization, synthetic aperture radar, and phased arrays. X band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement. X band is often used in modern radars. The shorter wavelengths of the X band al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 shoot down short-, medium-, and intermediate-range ballistic missiles in their terminal phase (descent or reentry) by intercepting with a hit-to-kill approach. THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991. The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile. 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, Israel, Romania, and South Korea. On 17 January 2022, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Defense Acquisition Program Administration
The Defense Acquisition Program Administration (DAPA) was founded on January 1, 2006 as part of a comprehensive reform of the defense acquisition project, including the introduction and development of weapons, and is a central administrative agency of the South Korean Ministry of National Defense. DAPA’s founding background In South Korea, the acquisition and procurement of military weapons was an important area that required a huge budget and determined national security. South Korea has also made several improvements in the Ministry of National Defense to reform its defense acquisition project in the process of strengthening its defense capabilities. Based on the evaluation results of the Yulgok project, which was a plan to reinforce and modernize the South Korean military, the Ministry of National Defense established an acquisition office in January 1999 by integrating the work related to the introduction of weapons into one department. However, as corruption scandals relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Sea
The Yellow Sea is a marginal sea of the Western Pacific Ocean located between mainland China and the Korean Peninsula, and can be considered the northwestern part of the East China Sea. It is one of four seas named after common colour terms (the others being the Black Sea, the Red Sea and the White Sea), and its name is descriptive of the golden-yellow colour of the silt-laden water discharged from major rivers. The innermost bay of northwestern Yellow Sea is called the Bohai Sea (previously Pechihli Bay or Chihli Bay), into which flow some of the most important rivers of northern China, such as the Yellow River (through Shandong province and its capital Jinan), the Hai River (through Beijing and Tianjin) and the Liao River (through Liaoning province). The northeastern extension of the Yellow Sea is called the Korea Bay, into which flow the Yalu River, the Chongchon River and the Taedong River. Since 1 November 2018, the Yellow Sea has also served as the location of "peace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Warfare
Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults. The purpose of electronic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. EW can be applied from air, sea, land, and/or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets. The electromagnetic environment Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum. The electromagnetic spectrum portion of the information environment is referred to as the electromagnetic environment (EME). The recognized need for military forces to have unimpeded access to and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations. Within the informat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Military
The United States Armed Forces are the military forces of the United States. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States. From their inception during the American Revolutionary War, the U.S. Armed Forces have played a decisive role in the history of the United States. They helped forge a sense of national unity and identity through victories in the First Barbary War and the Second Barbary War. They played a critical role in the American Civil War, keeping the Confederacy from seceding from the republic and preserving the unio ...

Republic Of Korea Air Force
The Republic of Korea Air Force (ROKAF; ko, 대한민국 공군; RR: ''Daehanminguk Gong-gun''), also known as the ROK Air Force or South Korean Air Force, is the aerial warfare service branch of South Korea, operating under the Ministry of National Defense of the Republic of Korea. History 1940s Shortly after the end of World War II, the South Korean Air Construction Association was founded on August 10, 1946, to publicize the importance of air power. Despite the then-scanty status of Korean armed forces, the first air unit was formed on May 5, 1948, under the direction of Dong Wi-bu, the forerunner to the modern South Korean Ministry of National Defense. On September 13, 1949, the United States contributed 10 L-4 Grasshopper observation aircraft to the South Korean air unit. An Army Air Academy was founded in January 1949, and the ROKAF was officially founded in October 1949. 1950s The 1950s were a critical time for the ROKAF as it expanded tremendously during the Korean ...

Vityaz Missile System
The S-350 Vityaz (russian: C-350 Витязь) is a Russian medium-range surface-to-air missile system developed by GSKB Almaz-Antey. Its purpose is to replace the S-300PS. The system design traces its roots from the joint South Korean/Russian KM-SAM project and uses the same 9M96 missile as the S-400 missile system. Development The first studies that would eventually become the S-350 started in 1999. Development began in earnest only in 2007. Almaz-Antey was able to leverage the experience gained while working on the joint development of the KM-SAM with South Korea. Around 2011, development slowed down, probably due to failed missile tests. The S-350 was unveiled in 2013, and presented at that year's MAKS airshow. Initial plans called for the system's test phase to end in the autumn of 2013, and for the delivery of around 30 systems by 2020. However, the first deliveries of the S-350 only took place in 2019, and it only entered service in February 2020. Design The S-350 ''Vityaz' ...

MIM-23 Hawk
The Raytheon MIM-23 HAWK ("Homing all the way killer") is an American medium-range surface-to-air missile. It was designed to be a much more mobile counterpart to the MIM-14 Nike Hercules, trading off range and altitude capability for a much smaller size and weight. Its low-level performance was greatly improved over Nike through the adoption of new radars and a continuous wave semi-active radar homing guidance system. It entered service with the US Army in 1959. In 1971 it underwent a major improvement program as the Improved Hawk, or I-Hawk, which made several improvements to the missile and replaced all of the radar systems with new models. Improvements continued throughout the next twenty years, adding improved ECCM, a potential home-on-jam feature, and in 1995, a new warhead that made it capable against short-range tactical missiles. ''Jane's'' reported that the original system's single shot kill probability was 0.56; I-Hawk improved this to 0.85. Hawk was superseded b ...
