Aiming at the main development problem of the weapon equipment architecture, a development method driving by data dictionary is proposed, which is based on the research of the basic idea of DoDAF V2.0. First, the initial data dictionary is given through the construction of the basic modeling data, and then this dictionary is used to drive and lead the process of the architecture development. The iterative method is used to perfect the data dictionary and solve the whole process of the architecture development, and verify it by example. The results show that this method can easily develop a specific complex weapon equipment architecture.
