Luoyang Optoelectro Technology Development Center

Luoyang Optoelectro Technology Development Center is a Chinese AVIC precision-guided-weapons and electro-optical systems organization based in Luoyang, Henan. Public exhibition and defense-reference sources identify LOEC with air-to-air missiles, launchers, ground test equipment, electro-optical tracking equipment, laser and infrared technologies, and the LS and LT precision-guided bomb families.

An AVIC exhibition directory described LOEC as belonging to China Aviation Industry Corporation I, founded in 1961, and located at No. 8 Tiyuchang Road in Luoyang. The same directory presented LOEC as a national research, development, and manufacturing center for air-to-air missiles, launchers, ground-test equipment, electro-optical tracking and observing devices, and related derivative products.

Open defense references connect LOEC to China's public precision-guided-munition displays at Zhuhai. GlobalSecurity reported that Luoyang showed the LT-2 500 kg laser-guided bomb and LS-6 glide-guided bomb at the 2006 Zhuhai air show, while Taipei Times and Air Power Australia connect LOEC source material to the LS-6 and LT-2 families.
