The LeiTing-2 (LT-2, LeiTing = “Thunder”) is the first Chinese domestically built laser guided bomb (LGB) that has entered operational service with the PLA. First revealed to the public in October 2006, the LT-2 bears a great deal of similarity to the Russian KAB-500L in appearance, suggesting that it may be a licensed or reverse-engineered copy of the Russian design. The 500kg bomb can be carried by a range of aircraft including JH-7, Q-5, FC-1, J-8B, and J-10. The weapon entered the PLA service in 2003/04. 

 “雷霆”（LeiTing）-2（LT-2，LeiTing=“thunder（雷鸣）”）是第一种本国制造的激光制导炸弹（LGB）已经进入PLA操作服役。在2006年10月对公众首次展示，LT-2在外观上具有大量同俄国KAB-500L的相似处，认为它可能是一种得到许可或反向工程俄国设计的仿造型。500公斤炸弹能被包括JH-7、Q-5、FC-1、J-8B和J-10多种飞机携带。武器在2003/04年进入了PLA服役。

China has been developing the LGB technology since the late 1980s, but with no known success before the introduction of the LT-2. Initially the Chinese LGB development used the U.S. design as a prototype. In the early 1990s China North Industries Group Corporation (NORINCO) revealed a LGB similar to the U.S. Paveway-II in appearance. The bomb features a laser guidance kit at the front end of the weapon; four front guidance fins (canards) which react to signals from the laser guidance kit and steer the weapon to the target, and four larger stabilising fins at rear.

中国从1980年后期以后发展LGB技术，但是由于在推出LT-2以前没有了解到具体成就。最初中国LGB发展使用了美国设计当做一个原型。在1990年早期中国北方工业（集团）总公司（NORINCO）展示了一种LGB外表与美国宝石路（Paveway）-2类似。炸弹在武器的前端以一个激光制导零配件为特点；四个前控制翼（鸭式）对来自激光制导零配件的信号产生反应而且操纵武器到目标，并且在后部有四个较大的稳定翼。

Development of the LGB accelerated after 2000 with Russian assistance. A full scale mockup of the Xi’an Aircraft Industry Corporation JH-7A fighter-bomber revealed in early 2002 featured an unknown model LGB. The fighter-bomber could guide the weapon using its own onboard laser targeting pod (self-designation). China has also  developed a range of laser targeting pods to be carried by combat aircraft for weapon guidance. An early design known as “Blue Sky” introduced in the late 1990s appeared to be similar to the U.S. LANTIRN navigation and targeting pod.

在2000年之后俄国的协助加速LGB的发展。在2002年早期显露的西安飞机工业公司JH-7A战斗轰炸机的一架全尺寸样机以一种未知型号的LGB为特色。战斗轰炸机可以使用它自己的机载激光瞄准吊舱（自己指示）引导武器。中国也已经发展多种的激光瞄准吊舱用于武器引导被战斗机携带。一种早期设计即“蓝天”在1990年后期内推出看起来相似美国LANTIRN导航和瞄准吊舱。

 

The LT-2 uses a semi-active laser guidance system, which requires a laser designator to “illuminate” the target for the weapon. The LT-2 could be guided by a laser targeting pod either carried by the same aircraft or onboard another aircraft. Alternatively it could also be guided by a land-based laser designator operated by the ground crew. The operational range is 15km for the airborne laser targeting pod and 7km for the land-based laser designator. The accuracy is estimated to be around 6.5m CEP.

LT-2使用一套半主动激光制导系统，需要一套激光指示器为武器“照明”目标。LT-2能被一套激光瞄准吊舱引导，被同一架飞机或另外的一架飞机两者携带。做为选择它也能被一名地面上的人员操作的陆基激光指示器引导。操作距离机载激光瞄准吊舱15公里和陆基激光指示器7公里。精度被估计大约6.5米圆概率误差（CEP）。
