In order to construct C4ISR with dynamic reconstruct ability under the Network Centric Warfare (NCW) circumstance, analyze the characteristics of network artillery C4ISR, give the concept of artillery C4ISR dynamic reconstruct substance and technology, introduce the dynamic reconstruct algorithm, routing algorithm on application layer and topological relations algorithm. And the answer shows that the ability of artillery C4ISR based on NCW can ensure the circulation of command information and enhance the battlefield survivability, it give a theory to guide the development of new artillery C4ISR.
