China Improves Missile Accuracy With Satellite Guidance

By WENDELL MINNICK, ABU DHABI, United Arab Emirates

Beijing-based China National Precision Machinery Import and Export Corp. (CPMIEC) has revealed new details of its P12 short-range tactical surface-to-surface missile at IDEX 2007.
Launched vertically from trucks, the solid-propellant P12 can carry a 450-kilogram cluster or high-explosive warhead up to 150 kilometers, company officials said. The missile has a circular error probable (CEP) of 80 to 120 meters on inertial guidance alone, 30 to 50 meters when incorporating satellite guidance, they said.
“The Chinese improved the guidance system of the SSM [surface-to-surface missile] with GPS or using the Russian GLOSNASS,” the Russian equivalent to the U.S. Global Positioning System, said Andrei Chang, founder of the Hong Kong-based Kanwa Defense Review. “The Chinese may also be using the GPS and GLOSNASS guidance technologies to improve the PLA version of short-range SSMs like DF-11 and DF-15 aimed at Taiwan.
“What this means is that Taiwan now faces precise ballistic missile threats.”
CPMIEC representatives said the Chinese army plans to field the P12 but could not say when.
The P12 prototype was displayed in October at the 6th China International Aviation and Aerospace Exhibition in Zhuhai, but no details were revealed.
Created in 1980 by parent company China Aerospace Corporation (CASC) to develop missiles, CPMIEC is the prime contractor and marketer for China’s Dong Feng (East Wind) missiles, which include the DF-11 (M-11) and DF-15 (M-9). Roughly 800 to 900 DF-11s and DF-15s are aimed at Taiwan.
CPMIEC’s aggressive missile program includes a variety of missiles launched from trucks, including the WS-2 Multiple Guided Launch Rocket System (MGLRS) with a range of 70 to 200 kilometers, the air-defense KS-1A missile that can hit targets up to 27,000 meters, and the surface-to-surface B611M missile with a range of 80 to 260 kilometers.
Chang said satellite guidance also gives the B-611M a CEP of less than 50 meters.
CPMIEC representatives said the Chinese army plans to field the B611M but could not say when.

国精密机械进出口公司在IDEX2007国际防务展上披露了P12近程战术弹道导弹的新信息。
该公司工作人员称，P12可携带重达450千克的集束战斗部或者高爆战斗部，最大射程为150公里。P12是一款机动式导弹系统，部署在轮式卡车上，采用垂直发射的方式。P12的CEP精度在单纯使用惯性制导系统时为80-120米，采用GPS/INS系统时为30-50米。
汉和防务分析员称，中国已经改进了弹道导弹的制导系统，通过加装GPS或GLOSNASS制导组件，提高了打击精度。而且，中国可能也采用了相同的技术去改进解放军自用的近程战术弹道导弹，如东风11和东风15，而这些导弹正瞄准着台湾。
这意味着，台湾现在面临的已经是精确弹道导弹的威胁。据粗略估计，有800-900东风导弹正瞄准着台湾。中国精密机械进出口总公司同时称，中国人民解放军也将装备P12近程战术弹道导弹，但没有说明部署时间。
中国精密机械进出口公司于1980年由中国航天科技工业集团创立，是中国“东风”系列导弹（包括DF-11/DF-15)的主要承包商和销售商。
中国精密机械进出口公司的导弹项目包括多种在轮式运输车上发射的导弹，其中有射程为70-200公里的WS-2多管制导火箭炮系统，KS-1A地空导弹系统和射程为80-260公里的B611M弹道导弹
汉和防务分析员称，卫星定位制导同样使B611M拥有CEP50米以下的攻击精度。
