Definition of ALTBMD Architectures by Applying the C4ISR Architecture Framework

Simulation systems have been used to support the evaluation of C4ISR architectures for ballistic missile defense, however, the application of structured analysis tools of the C4ISR community to support the design of respective simulation runs is not found often. Within the preparation of simulation analysis of different C4ISR architectures for a NATO Active Layered Theatre Ballistic Missile Defense Feasibility Study, our study team used the C4ISR Architecture Framework (Version 2.0) of the US DoD Architecture Working Group (AWG) for the preparation of the simulation runs with our Tactical Missile Defense Simulator (TMDSIM). The use of this application is proving to be very successful. This paper will present how the C4ISR Architecture Framework is applied to reduce the large and unmanageable number of architectures while increasing the simulation level of fidelity. This process is planned to be performed in three steps: In the first step, TMDSIM is being applied to down-select a set of candidates from a large number of possible architectures. In the second step, the set of candidates will be examined with EADSIM to define a few recommended architectures. In the third step, EADTB will be applied to examine the recommended architectures and to determine their performance. The focus of this paper is on the first step, the down-selection process.
