AMSWR

• Purpose Exercise Support
• Support the COMSULANT Immediate Need to Conduct
  Mine Detection Avoidance Littoral ASW
  Operations At the Berry Islands
• Support All Platform Organic Mine Counter
  Measures (MCM)
• Support TE Events and Tactics Experimentation
  and Development
• Provide Effective and Efficient All-platform Mine
  Detection Avoidance Training
• Realistic Environment
• Realistic Targets
• Real-time Exercise Data Collection, Display and
  Analysis
• Affordable Operation and Maintenance
• Support Future Organic MCM Systems Test and
  Evaluation

AMSWR

• Current Needed Capabilities
• Environmentally Realistic Area Including Water
  Depth, Bottom Composition, and Acoustics
• Realistic Targets (Mine Shapes) Representing
  Commonly Expected Mine Threats
• Exercise Reconstruction, Analysis, and Feedback
• Underwater Tracking
• Above Surface Tracking and Communications
• Operational Considerations
• Affordable Operational Cost
• Post IOC MO Costs TBD
• Low Operational Risk
• Shore Based Much Less Weather Constrained Than
  Shipboard Operations
• Trunk Cable And Exposed Systems Protected From
  Fishing
• Remote Diagnostics Provide State of the System
  Status
• Provide Capability for Exercise Conduct, Safety,
  and Debrief

AMSWR

• OPTEMPO
• Submarines From Day of IOC
• 23-25 SSNs every 12-15 mos. _at_ 8-10 hrs. each
• Occasional TACDEVEXs (estimate 2/year _at_ 5 days/24
  hrs each)
• Assumes PCO Exercises 2/year
• BG deployers (2 SSNs/BG, 2 1/2 BGs/year, 8-10
  hrs/SSN)
• OTE Events
• A-RCI HF Phase IV sonar APB
• Advanced Mine Simulation System (AMISS)
• Foreign Mine Surrogate Targets (FORTS)
