The need of fighting determines the mode of safeguard. The new need of the information warfare in high-tech conditions not only changes the war form and the fighting way, but also bring the new challenge to the equipment support model which is traditional and mature. The equipment support status and the existing prob- lems are analyzed. Based on the analysis a supposition of three-dimensional safeguard model is put forward, which is ＂the early stage of the design＋the spare parts＋equipment＂. The equipment module design, spare parts management, test equipment, information resource management and service information are specifically explained, which involve in full life cycle. A proposal is presented to meet the needs of information-based war equipment support and provide the equipment support with ＂timely, accuracy, high quality, high efficiency, low consumption＂.
