- NO PERFECT SYSTEM
- Scenario variables were the key factors
- Each alternative studied had weaknesses
- Differences between alternatives were significant
- Best solution might be a tailored mix

- REACTION TIME
- Enemy submarines are vulnerable in restricted
waterways - Enemy timelines are unpredictable
- Quick reaction systems hedge uncertainty
- Strategic air least sensitive to enemy initiative

13ASW Results, Insights and Recommendations
- KILL-CHAIN TIMELINE (KCT) TRADEOFFS
- Traditional methods require short KCTs
- Non-traditional methods afford longer KCTs
- Standoff weapons systems more easily used if
longer KCT are allowed

- UNDERSEA JOINT ENGAGEMENT ZONE (UJEZ)
- Cooperative mix of assets unlocks future ASW
force capabilities - Future ASW forces may require the establishment
of the UJEZ - Low false positive and low fratricide rates are
required
