A revised architecture concept for ASW information management by reducing shore-to-ship and inter-platform data transmission time and bandwidth requirements through cost effective management of information is now possible. Application of the information management methodology to the storage, retrieval, and timely presentation of coherent tactical pictures will be important by-products. Proper information management is the key. The first objective is to establish information requirements by establishing a concept for a set of time-phased architecture options leading to the satisfaction of top level warfare requirements (TLWR) as ASW information management. The second objective is to create a plan that will provide for the transition from the baseline architecture to the preferred architecture options. This is to be a refinement of a previously approved and executed Phase I proposal under contract n00039-89-c-0249 to allow for Phase II implementation .
