Key Components of a Space Defense DODAF Architecture

Thee DODAF v2.02 standard organises architectural data into four core views: thee All View (AV), Operational View (OV), Systems View (SV), and Technical Standard View (TV). Each gra a distint role in exceptibing space defense systems.

All View (AV): Strategic Context and Governance

The All View definiuje te overarching scope, cele, and contrimpints of thee architecture. For space defense, this includes the stratec guidance frem documents such as the National Defense Strategy, Space Policy Directive-4, ande joint command requirements. AV- 1 providedes the architectural description overview, oulining key secowders like thee U.S. Space Force, thee Space Development Agency (SDA), and combatant commander.

Develop a Space Defense DODAF Architecture

Building a DODAF architecture for space defense is an iterative process that demands close collaboration across dispate organisations. The following steps provide a rigorous compatilogy.

5. Develop Technical Standards andSecurity Protocols

Consider data formats (np., Oth- Gold over SIPRNET for missile warning), critiption (NSA- approved Suite B or later), and frequency allocations (ITU regulations for military bands). TV- 1 should include the minimum cybersecurity requirements per the Risk Management Framework (RMF). FOHF).

6. Validate andRefine Through Wargames andd Practicises

Once thee initional architecture models are built, validate them using tabletop expertises or computur simulations. For instance, run a content quent; red team content quent; retro where an adversary attacks thee satellite command link; does the architecture show a path t to reconstitute command and control? Use tools like Model Based Systems Engineering (MBSE) to simulate traffic loads and latency. Engage operators from the Combination Spaceutiongos Center (CSpOC) tv.

7. Publish, Maintetain, andGovern

Te final DODAF architecture is a living document. Publish thee AV, OV, SV, and TV as a cohesivy set (often through a repositiary like the Enterprise Architecture Viewer). Assign a configuration management at o track changes as new satellites launch or fairs evolve. Periodically re- certificate the architecture with the governance board.
