Homar-K
The K239 Chunmoo () is a rocket artillery system developed in 2013 to replace the aging K136 Kooryong of the South Korean military. History South Korea struggled to come up with countermeasures in the 1970s when North Korea deployed BM-21 Grad, a new multiple rocket launcher (MRL) brought in from the Soviet Union. At that time, the possibility of fatal casualties increased if Howitzer, towed howitzers, self-propelled artillery, self-propelled howitzers, and multiple rocket launchers deployed by the Korean People's Army, North Korean military fired at the South Korea. The South Korean military developed the K136 Kooryong in 1978 to counter the threat of North Korean artillery. With the deployment of Kooryong to the Republic of Korea Army, South Korean Army since the 1980s, it was temporarily able to maintain a similar balance to North Korea's artillery power. However, over time, problems such as the discontinuation of the main parts of the aging Kooryong system have been reveale ...

Ure (missile)
The Ure (Hangul: 우레; English language, English: Thunder), often called KTSSM (Korean Tactical Surface-to-Surface Missile; ) is a short-range tactical surface-to-surface missile (SSM) developed through the Lightning Project () that began as a countermeasure against North Korea's conventional artillery raised in the wake of the Bombardment of Yeonpyeong, Bombardment of Yeonpyong Island. The Block 1 for fixed launcher platform, which was developed in 2019, was jointly developed with Hanwha Group under the leadership of Agency for Defense Development (ADD) and is currently developing an improved Block 2 version to operate on various transporter erector launcher (TEL) platforms. Design and development The KTSSM (Ure) was developed with the intention of quickly neutralizing North Korean long-range artillery. Dubbed the "artillery killer," Hanwha Corporation designed the missile in partnership with the Agency for Defense Development (ADD). Four missiles can be launched almost simult ...

HD Hyundai Infracore
HD Hyundai Infracore Co., Ltd. (), formerly known as Doosan Infracore, is a South Korean company that manufactures construction equipment and commercial and military engines. It is one of the largest construction equipment manufacturers by sales revenue. Doosan Infracore was acquired by HD Hyundai (former Hyundai Heavy Industries Group) in 2021. History Daewoo Heavy Industries Daewoo Heavy Industries was founded in 1937 as Chosun Machine Works when Korea was under Japanese rule. After Japan's withdrawal from Korea, the company was nationalized by the government and was transformed into a public company in 1963 as Hankook Machine Industrial. In 1969, Hankook Machine was privatized after being sold to Shinjin Group. In 1975, the company began producing diesel engines with financial support from the German government and technical collaboration with MAN SE. However, the company was financially strapped due to the lack of domestic demand and unstable direction, and Shinjin had t ...

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Circular Error Probable
Circular error probable (CEP),Circular Error Probable (CEP), Air Force Operational Test and Evaluation Center Technical Paper 6, Ver 2, July 1987, p. 1 also circular error probability or circle of equal probability, is a measure of a weapon system's Accuracy and precision, precision in the military science of ballistics. It is defined as the radius of a circle, centered on the aimpoint, that is expected to enclose the landing points of 50% of the Round (firearms), rounds; said otherwise, it is the median error radius, which is a 50% confidence interval. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, an average of 50 will fall within a circle with a radius of 100 m about that point. There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, a form of the standard deviation. Another is the R95, which is the radius of the circle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Artillery
Rocket artillery is artillery that uses rockets as the projectile. The use of rocket artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon). Fire arrows were also used in multiple launch systems and transported via carts. In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War. Modern rocket artillery was first employed during World War II, in the form of the German Nebelwerfer family of rocket ordnance designs, Soviet Katyusha-series and numerous other systems employed on a smaller scale by the Western allies and Japan. In modern use, the rockets are often guided by an internal guiding system or GPS in order to maintain accuracy.
