YZ is a series of precision-guided munitions (PGM) developed by China Aerospace Science and Industry Corporation (CASIC). [1]
The Chinese development of the precision-guided bomb began in the 1970s after the Chinese military observed the American usage of Paveway in the Vietnam War. Factory 624, later known as the Harbin Jiancheng Group, a subsidiary of Norinco, began the development process in 1974, with prototypes completed in 1980. Between 1984 and 1985, the guided bomb was tested via ground laser designation, while in 1986, the bomb was tested with an aerial laser targeting pod prototype. Prototypes were tested on the H-5 bomber. The project was canceled in the late 1980s due to budgetary issues. [2] The prototype guided bomb in the canceled project was designated Type 7712. [3]
A new laser-guided bomb project was initiated in 1992 after Chinese observation of the Gulf War. This project received more budgetary, human, and political resources. The bomb system was tasked to the Luoyang-based China Airborne Missile Academy (CAMA, 612th Research Institute), and the targeting pod was tasked to the Luoyang Optoelectro Technology Development Center (LOTDC, 613th Research Institute), and the production was tasked to the Factory 624 (Harbin Jiancheng Group). The final product was LS-500J laser-guided bomb, later renamed LT-2 laser-guided bomb for export. [2] LS-500J (LT-2) was one of the most widely used guided bombs in China's arsenal. [2] [4]
Eventually, the original LS-500J branched out to the other series of guided bombs, [2] which were manufactured by different defense factories and institutions: [5]
The YZ-100 series debuted at Zhuhai Airshow 2010. [14] In 2012, YZ-100 showcased three different weight class, including 30 kg (66 lb), 50 kg (110 lb), and 100 kg (220 lb). [13]
YZ-100 are cluster bombs with precision-guided sub-munitions, and different guidance systems, such as inertial, satellite, laser, infrared, and millimeter wave radar, can be adopted for each sub-munition.
YZ-102A was showcased with the CAIG Wing Loong drone in Egyptian military service. [15]
The YZ-200 series also debuted at Zhuhai Airshow 2010. [16] One variant within the YZ-200 series is called YZ-212, [17] which is laser-guided. [18] In 2012, YZ-200 showcased three different weight class, including 50 kg (110 lb), 125 kg (276 lb), and 250 kg (550 lb). [13]
The Xi'an JH-7, also known as the FBC-1 Flying Leopard, is a Chinese tandem two-seat, twin-engine fighter-bomber in service with the People's Liberation Army Naval Air Force (PLANAF), and the People's Liberation Army Air Force (PLAAF). The main contractors are Xi'an Aircraft Industrial Corporation (XAC) and the 603rd Aircraft Design Institute.
The Type 99 or ZTZ-99 is a Chinese third generation main battle tank (MBT). The vehicle was a replacement for the aging Type 88 introduced in the late 1980s. The Type 99 MBT was China's first mass-produced third-generation main battle tank. Combining modular composite armour and tandem-charge defeating ERA, 125 mm smoothbore gun with ATGM-capability, high mobility, digital systems and optics, the Type 99 represents a shift towards rapid modernization by the PLA.
TY-90 is a Chinese air-to-air missile specifically developed for attack helicopter dogfights. Contrary to erroneous claims, the missile is not developed from MANPADS missiles, but instead, it is specifically designed as an air-to-air missile to engage in helicopter combat.
The Type 80 and the Type 88 are a family of Chinese second-generation main battle tanks (MBTs). They are also known as the ZTZ80 and ZTZ88.
Fei Teng, abbreviated as FT, is a series of precision-guided munitions (PGM) developed by China Academy of Launch Vehicle Technology (CALT), a subsidiary of China Aerospace Science and Technology Corporation (CASC). Competing with the LS series, the FT series bombs serve similar roles to the American JDAM, JDAM-ER, and Laser JDAM bombs.
Lei Ting, abbreviated as LT, is a series of precision-guided munitions (PGM) developed by Luoyang Optoelectro Technology Development Center (LOTDC), a subsidiary of Aviation Industry Corporation of China (AVIC). The first variant, LT-2, was one of the most produced laser-guided bombs in the Chinese military. The role and performance of the Lei Ting series are roughly equivalent to the Paveway.
Lei Shi, abbreviated as LS, is a series of precision-guided munitions (PGM) developed by Luoyang Optoelectro Technology Development Center (LOTDC), a subsidiary of Aviation Industry Corporation of China (AVIC). Leishi is a type of guidance kit that can modify existing unguided bomb into guided standoff munition. These maneuverable guided bombs are similar in roles to the American Joint Direct Attack Munition (JDAM) kit but with longer ranges.
A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a guided munition intended to hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the Persian Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
The LG5 is a semi-automatic grenade launcher developed by Norinco and introduced in 2011. The launcher's designation "QLU" stands for "light weapon - grenade (Liúdàn) - sniper (Jūjī)" in Chinese military coding standard.
The Wing Loong-10 is a series of unmanned aerial vehicles of the High-Altitude Long Endurance (HALE) type, featuring some stealth characteristics. As of 2017, it is being developed by the Chengdu Aircraft Industry Group for reconnaissance and precision strike missions.
KD-88 (Kongdi-88) is a standoff land attack missile built by China Aerospace Science and Technology Corporation (CASC). Its export version is called TL-17.
BRE is a series of guided rockets (missiles) manufactured by Chinese Norinco.
Lei Jiayin is a Chinese actor best known for his roles in the films Guns and Roses (2012), How Long Will I Love U (2018), A Writer's Odyssey (2021), Full River Red (2023), and YOLO (2024), as well as the television series The First Half of My Life (2017), The Longest Day in Chang'an (2019), and A Lifelong Journey (2022).

The QJS-161 Paratrooper Machinegun, also known as the QJB-201 Squad Machinegun, is a Chinese light machine gun designed and manufactured by Norinco for the People's Liberation Army Ground Force and Airborne Corps.
The CS/LR4 7.62 mm High-Precision Sniper Rifle System, also known as NSG-1, is a bolt-action sniper rifle designed and manufactured by Chinese company Norinco. The rifle features a free-floating barrel and is chambered in the specifically designed CS/DFL3 (7.62×51mm) high-precision cartridge in a 5-round box magazine, while can also accept other .308 Winchester ammunition.
