  1. Modeling & Simulation for Enterprise Test and Evaluation Shala Malone Combat Systems Performance ManagerPEO IWS Rich Reading Cutlass Systems Engineering 9 May 2007 Distribution Statement A: approved for public release.

  2. Operational Context: Ship Self Defense Ship Defense MOE Probability of Raid Annihilation (PRA) is the ability of a particular stand-alone ship as a system to detect, control, engage, and defeat a specified raid of threats within a specified level of probability in an operational environment • Subsonic, supersonic, high diver • Hi-G maneuvers • Multi-mode seekers BattleTimeline ≈ 30 seconds BattleSpace ≈ 0-12 nmi

  3. Enterprise Test & Evaluation Master Plan The purpose of the Capstone Enterprise Air Warfare Ship Self Defense (AW SSD) Enterprise Test and Evaluation Master Plan (TEMP) is to consolidate all AW SSD at-sea testing and PRA Testbed testing • The AW SSD T&E Enterprise Strategy is founded on a two-tiered process to assess AW SSD warfare systems performance: • 1) Validate models with live testing • Operational Ship testing • Self Defense Test Ship (SDTS) testing • 2) Assess performance with models Test Events DT/OT-ET15 thru ET19are formal PRA Testbed events Includes DDG 1000, LHA 6, LCS and CVN 21 ship classes

  5. Enterprise PRA Testbed System Engineering – Drivers for Centralized IWS Leadership • Systems performance for PRA assessment spans different technical communities and multiple managing program offices • PRA will be assessed using a federation of interoperable simulations; it will not (cannot) be tested empirically • Complex, multi-spectral, integrated HK/EW problem space • Many specific parameters, assumptions, and limitations are negotiated between the testing and acquisition communities • The testing community is intent on consistent PRA assessment across ship classes and warfare system configurations • Different hulls, different configurations…same threat models, same virtual range conditions

  6. Enterprise PRA Testbed Components “Virtual Range” (Infrastructure) • Testbed Architecture: network interface layer, interface standards, functional allocation standards • Common Threat Models: seeker, airframe/autopilot, signatures, vulnerability • Common Environment Models: tailored authoritative databases, runtime environment data services “Virtual Test Ship”(specific to ship class) • Ship Characteristics • Signature, motion, launcher placements, etc. • Combat System Representation • Authoritative, “T&E quality” models of combat system elements “Virtual Range” Testbed Architecture Common Threat Common Environment Testbed Component Providers: IWS 7D Ship Class PM IWS Project Offices Navy PRA Testbed Ship Class Baseline Combat System Element Combat System Element Combat System Element Combat System Element Ship-specific Characteristics “Virtual Test Ship”

  7. Enterprise Testbed Construct • Provides Enterprise-level definitions and guidance for Testbed development • Single master document addressing: • CONOPS • Roles & responsibilities • Federation system engineering • Simulation architecture • Virtual Range development and use • VV&A process management • Configuration management • Draft in-process

  8. Current Simulation Framework Characteristics • HLA federation implementation • All system representations execute simultaneously for each ship defense engagement • Geographically distributed • Constructive simulation, conservative time management • System representations are a mix of digital models and tactical software • Most representations are a hybrid of tactical SWIL and digital model • Most tactical SW re-hosted to general purpose computers

  12. Challenges Ahead • Relationship of PRA Testbed simulations to other M&S supporting system development and T&E • Improved mechanisms for injecting data needs into planning of empirical tests • Feedback of knowledge and capabilities to early phase acquisition systems engineering • Extension of PRA Testbed to address other MOEs • Evolution of PRA Testbed to next spiral of T&E Enterprise • battlespace extension, force level representation
