The Electro-Optic Targeting System (EOTS) is replacing the traditional all-optical targeting system as the oncoming generation targeting system to meet all-weather fast and precise bombing. The applying status through its system composition, model and realization approach is presented, and meanwhile the development trend of electro-optic bombing targeting system is analyzed (appearance blending into the aircraft，incorporated to Distributed Integrated Electro-Optic System). The thesis may be helpfully to research new bombing electro-optic targeting system and consequently boost the bombing function.
