One-time setup
$176.4M
Annual recurring
$40.0M
Personnel
66
Initial one-time build-out is driven by a robust hydrophone network, surface/air/undersea assets and a large contingency reserve (~$176M one-time). Recurring costs are dominated by 24/7 sonar staffing, vessel/air operations, ROV/AUV ops, legal/cover and contingency reserves (~$40M/year).

⚡ Cost Scenarios
📊 Baseline (baseline) $40.0M/yr
83.0% probability / year
Normal year with no major incidents: ongoing monitoring, routine maintenance, staffing, legal/cover and reserves.

🚨 Major Breach $110.0M/yr
2.0% probability / year +$70.0M vs baseline
Large-scale escalation: multiple ship losses, destruction of Foundation assets and heavy international/diplomatic fallout requiring major salvage, replacement fleet procurement and mass amnestic/PR operations.
