Initial capital for a single, fully hardened aquatic containment habitat is estimated at roughly $15.4M, driven mainly by tank construction, environmental systems, EMP hardening and heavy-duty life-support/response equipment. Annual operating costs are about $3.77M/yr, driven by staffing (security and animal care), energy/maintenance for chillers and pumps, research, waste handling and contingency reserves.

⚡ Cost Scenarios
📊 Baseline (baseline) $3.8M/yr
88.0% probability / year
Normal operational year with routine maintenance, research and no major containment incidents.
routine_maintenance scheduled_research no_breach_events
🚨 Minor Incident $4.6M/yr
10.0% probability / year +$800K vs baseline
Small-scale containment event (localized EMP damage, minor animal injuries or small release) requiring emergency response, repairs, and limited legal/cleanup costs.

🚨 Major Breach $8.8M/yr
2.0% probability / year +$5.0M vs baseline
Significant containment breach or radiological event (large EMP-amplified event, loss of multiple specimens, major contamination) triggering decontamination, legal action, replacement and possible decommissioning.

📋 Confidence Notes
Detailed line-item ranges were provided, but large uncertainties remain around specimen-driven EMP behavior, potential radiological amplification events and scale of remediation after major incidents; catastrophic tail risks and location-dependent build costs reduce confidence.
