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. The prototype guided bomb in the canceled project was designated Type 7712. 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. LS-500J (LT-2) was one of the most widely used guided bombs in China's arsenal. Eventually, the original LS-500J branched out to the other series of guided bombs, which were manufactured by different defense factories and institutions: • The LS and LT series guidance bomb kits, with the LS series focusing on satellite glide bomb, whereas the LT focus on laser guidance, produced by Luoyang Optoelectro Technology Development Center of Aviation Industry Corporation of China (AVIC). • The FT series of guided bombs, produced by China Aerospace Science and Technology Corporation (CASC). • The TG, TD, and TL series of guided bombs, produced by various subsidiaries of Norinco, such as Harbin Jiancheng Group. • The YL and YJ series of guided bombs, produced by China South Industries Group and marketed via Norinco. • The YZ series guided bomb, produced by China Aerospace Science and Industry Corporation (CASIC).

LS-6 precision-guided bomb was initially revealed at the 2006 Zhuhai Airshow. LS kit is a strap-on upgrade package to provide general-purpose bomb with range extension and precision strike capabilities. The kit consists of two modules: the guidance module and gliding wings. The guidance module includes inertial/satellite guidance, typically mounted in the tail cone of the weapon, and electro-optical seeker with scene matching area correlator or laser guidance seeker, which is mounted at the tip of the bomb. The gliding module, including the folding wings and cruciform tail control surfaces, is made of composite material and comes in different versions for different sizes of gravity bomb, such as, and. The range for the bomb is at knot with release attitude of. A miniaturized turbojet kit can be mounted at the aft end, boosting LS-6's range to. LS kit series uses the GJV289A standard, the Chinese equivalent of MIL-STD-1553B. The adaptation of such military standards means that the weapon can be readily deployed on any Western platform. The and variants of the LS-6 are externally similar to the GBU-39 Small Diameter Bomb, which can be carried in the internal weapons bays of stealth fighters such as the Chengdu J-20. LS6 equipped munitions were spotted integrated onto Serbian MiG-29s for the first time in March 2026, around the same time that photographs revealed the integration of CM-400s onto the same type of aircraft.

• Type 7712: Prototype laser-guided bomb. Marketed as LT-1 for export by Norinco in the early 1990s. The marketing was halted after the project cancellation. • LS-500J: First generation of the laser-guided bomb. Renamed to LT-2 for export. In PLAAF service, the LS-500J (LT-2) is designated K/YGB500. • LS-6/500: LS-6 glide bomb kit with a pair of horizontal wings mounted on a unguided bomb. The guidance module consists of GNSS and INS. • LS-6/250: LS-6 glide bomb kit with a pair of horizontal wings mounted on a unguided bomb. The guidance module consists of GNSS and INS. • LS-6/100: LS-6 glide bomb with compact control surfaces and a nose-mounted electro-optical seeker mounted on a unguided bomb.
