K21 (Rapper)
The K21 is a South Korean infantry fighting vehicle. A replacement for the K200-series, it was formerly designated as K300 or XK21 KNIFV (Korea Next-generation Infantry Fighting Vehicle). The initial production began in 2009, with the Republic of Korea Army planning to field approximately 466 units. It is designed to effectively defeat other IFVs as heavily armed and armored as the BMP-3. History Development began in 1999. A $77 million contract was awarded to Doosan DST for the NIFV prototype in 2003. Three prototype vehicles were delivered to the ROK Army in 2005. A contract for the first batch of K21 vehicles was signed in October 2008 worth $386.7 million. Production began in November 2009 after a ten-year development period. K21s will be deployed from 2013 through 2016. Design Construction The K21 KNIFV's chassis is constructed entirely out of aluminium with certain parts, like hatches, made of fiberglass, reducing the weight of the vehicle and enabling it to travel ...

Infantry Fighting Vehicle
An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit. Infantry fighting vehicles are distinct from armored personnel carriers (APCs), which are transport vehicles armed only for self-defense and not specifically engineered to fight on their own. IFVs are designed to be more mobile than tanks and are equipped with a rapid-firing autocannon or a large conventional gun; they may include sid ...

ROK Army
The Republic of Korea Army (ROKA; ko, 대한민국 육군; Hanja: 大韓民國 陸軍; RR: ''Daehanminguk Yuk-gun''), also known as the ROK Army or South Korean Army, is the army of South Korea, responsible for ground-based warfare. It is the largest of the military branches of the Republic of Korea Armed Forces with 420,000 members . This size is maintained through conscription; South Korean men must complete military service (18 months for army, auxiliary police and marine, 20 months for navy and conscripted firefighter, 21 months for air force and social service, 36 months for alternative service) between the age of 18 and 35. History The modern South Korean army traces its lineage back to the Gwangmu Reform, when the Byeolgigun was established by Emperor Gojong in 1881. The 1st of every October is celebrated in South Korea as Armed Forces Day. It commemorates the day during the Korean War when units of the ROK Army first crossed the 38th Parallel, thus leading the ...

ATGM
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave lig ...

Air Burst
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion (as well as any shell fragments) is distributed more evenly over a wider area; however, the peak energy is lower at ground zero. History Air burst artillery has a long history. The shrapnel shell was invented by Henry Shrapnel of the British Army in about 1780 to increase the effectiveness of canister shot. It was widely used by the time of the War of 1812 and stayed in use until it was superseded during the First World War. Modern shells, though sometimes called "shrapnel shells", actually produce fragments and splinters, not shrapnel. Air bursts were used in the First World War to shower enemy positions and men with shrapnel balls to kill the largest possible number with a sing ...

Proximity Fuse
A proximity fuze (or fuse) is a fuze that detonates an explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. 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 th ...

Puma (IFV)
The Puma is a German infantry fighting vehicle (IFV) ( or short ''SPz'') designed to replace the aging Marder IFVs currently in service with the German Army. Production of the first batch of 350 vehicles began in 2010 and was completed in August 2021. A second batch of 229 Pumas received funding. Mass production began on 6 July 2009. The companies responsible for this project are Krauss-Maffei Wegmann and Rheinmetall Landsysteme, which created a joint venture, Projekt System Management GmbH (PSM). The Puma is one of the world's best-protected IFVs, while still having a high power-to-weight ratio. Eighteen Pumas took part in exercises in 2022, and all of them were inoperable at the end of the exercises. Major General von Butler, the commander of the 10th Armoured Division, described the situation as a "total failure." Consequently, the German government has paused purchases of further Pumas. History Development The Puma (formerly also named ''Igel'' (hedgehog) and ''Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APFSDS
Armour-piercing fin-stabilized discarding sabot (APFSDS), long dart penetrator, or simply dart ammunition, is a type of kinetic energy penetrator ammunition used to attack modern vehicle armour. As an armament for main battle tanks, it succeeds Armour-Piercing Discarding Sabot (APDS) ammunition, which is still used in small or medium caliber weapon systems. Improvements in powerful automotive propulsion and suspension systems following World War II allowed modern main battle tanks to incorporate progressively thicker and heavier armour protection systems, while maintaining considerable maneuverability and speed on the battlefield. As a result, achieving deep armour penetration with gun-fired ammunition required even longer anti-armour projectiles fired at even higher muzzle velocity than could be achieved with stubbier APDS projectiles. History Armour-piercing discarding sabot (APDS) was initially the main design of the kinetic energy (KE) penetrator. The logical progression ...

Close-in Weapon System
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Example ...
