Operational context ship self defense l.jpg

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


Enterprise test evaluation master plan l.jpg

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

Enterprise p ra testbed system engineering drivers for centralized iws leadership l.jpg

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


Enterprise p ra testbed components l.jpg

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

Enterprise testbed construct l.jpg

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


Current simulation framework characteristics l.jpg

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
