QJZ-89
The QJZ-89, also known as the Type 89 heavy machine gun, is a heavy machine gun designed in the People's Republic of China and fires the Soviet 12.7×108mm ammunition. History In the early 1980s, Chinese firearms designers received scattered information from Soviet publications regarding the Soviet Union's adoption of a new heavy machine gun called the NSV. Chinese weapons industry misconstrued gun weight data of as the whole system weight due to a translation error. Astonished by the misinterpreted capability of the NSV, Chinese designers began to develop a comparable weapon system. Only after the development ended did they realized the weight figure didn't include the tripod. The weapon features a hybrid gas and recoil operated action. The gas system cycles the bolt group with the receiver recoils inside the outer gun housing to decrease peak recoil. The gun uses a direct impingement gas system, similar to Type 85 machine gun. Type 89 was named "lightweight heavy machine gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
W85 Heavy Machine Gun
The W-85 heavy machine gun or QJC-88 vehicle mounted heavy machine gun is a gas-operated heavy machine gun designed in the People's Republic of China. It fires the Soviet-designed 12.7×108mm round. The W-85 was never accepted into the PLA service in its original configuration, only adopted as vehicle mounted machine gun as the QJC-88. Another similar named Type 85 heavy machine gun, was adopted as the standard infantry heavy machine gun in the PLA. Overview The W85 was designed to be as light as possible for infantry use. Its small receiver is of generally rectangular cross-section, and it has a thick gas tube below the barrel containing a conventional gas piston. In addition to iron sights, it has rails for optics or anti-aircraft sights. It fires 12.7×108mm rounds from belts and is more accurate than the Type 54 heavy machine gun, but the thinner barrel overheats faster. In trials, the W85 lost out to the Type 85 as an infantry weapon and was not accepted into PLA serv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light machine gun, light, medium machine gun, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require weapon mount, mounting onto a weapons platform to be operably stable or tactically mobility (military), mobile, have more formidable firepower, and generally Crew-served weapon, require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber (12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration (weapons), penetration and stopping ...

Saboted Light Armor Penetrator
The saboted light armor penetrator (SLAP) family of firearm ammunition is designed to penetrate armor more efficiently than standard armor-piercing ammunition. In the US it was developed by the Marine Corps during the mid/late 1980s and was approved for service use in 1990 during Operation Desert Storm. It uses a reduced caliber, heavy metal (tungsten) .30 inch diameter penetrator wrapped in a plastic sabot of .50 inch diameter, and the .308 SLAP round was a .223 inch diameter penetrator core within the .308 inch plastic sabot. Design and use The SLAP design incorporates a polymer sabot, which allows for the use of a tungsten penetrator projectile of a lesser diameter than the original bore. By using the casing of a large cartridge with a lightweight projectile, the velocity of the projectile is greatly increased and the sectional density is improved without requiring a (potentially dangerous) increase in chamber pressure. SLAP rounds have been designed for use against ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Guns Of The People's Republic Of China
A machine is a physical system using power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and control com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War Weapons Of China
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

XM312
The XM312 is a heavy machine gun derived from the XM307 25 mm autocannon and chambered for the .50 BMG cartridge. It was designed in response to a request by the Military of the United States, U.S. military for a replacement for the aging M2 Browning heavy machine gun, and as a complement to the heavier XM307 Advanced Crew Served Weapon grenade launcher. It is capable of being converted quickly into an XM307 with a small number of parts and a few minutes of work at the unit level (and vice versa from the XM307). The Fiscal Year 2008 Appropriations bill awarded $10 million to General Dynamics for the XM307 and XM312. In May 2008 the United States Army, U.S. Army had awarded General Dynamics Armament and Technical Products (GDATP) a $9 million contract to develop a lightweight .50-caliber machine gun called the XM806 to supplement the Browning M2. The XM806 was canceled in 2012. The Army at present will continue buying new M2s and Mk 19s to replenish the current guns that are ...

Dongfeng EQ2050
The Dongfeng EQ2050 is a Chinese-made armored vehicle based on the Humvee, manufactured for government use by the Dongfeng Motor Group. It is known to be sold by the company for 700,000 Yuan ($93,000). The vehicle was created after People's Liberation Army (PLA) officials saw the Humvee deployed in the Gulf War. While it is used in the PLA, it has also been exported to friendly countries for military use. The EQ2050 is largely being replaced in its role by the newer Dongfeng Mengshi class of vehicles. History AM General presented a Humvee to the PLA for a demonstration in 1988 at the Beijing Defence Exhibition. The PLA were not interested in the vehicle, due to concerns of high maintenance costs and the vehicle's bulky size. The Humvee was seen in action worldwide via television during Operation Desert Storm, which gave the PLA second thoughts about having a similar vehicle for military use. The Chinese petroleum industry purchased civilian Hummers in the 1990s. This gave Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armour-piercing Discarding Sabot
Armour-piercing discarding sabot (APDS) is a type of spin-stabilized kinetic energy projectile for anti-armour warfare. Each projectile consists of a sub-calibre round fitted with a sabot. The combination of a lighter sub-calibre projectile with a full-calibre propellant charge allows for an increase in muzzle velocity compared to full-calibre rounds, giving the round increased armour-penetration performance. To further enhance their armour-penetration capabilities, APDS rounds typically feature a hardened core made from tungsten or another hard, dense material. For a given calibre, APDS ammunition can effectively double the armour penetration of a gun when compared to full-calibre rounds such as AP, Armour-piercing Capped (APC), and Armour piercing Capped Ballistic Cap (APCBC) projectiles. APDS-rounds were commonly used in large calibre tank guns up until the early 1980s, but have since been superseded by armour-piercing fin-stabilized discarding sabot (APFSDS) projectiles, ...
