SCP-4683

Expected annual

$13.7M

One-time setup

$78.7M

Annual recurring

$10.5M

Personnel

Initial capital costs are dominated by containment-suite construction, specialized lab and R&D (nexus-dampening) development, and large emergency reserves; annual operations are driven by research, surveillance, and staffing for rapid-response teams, with expected baseline recurring costs in the low tens of millions.

⚡ Cost Scenarios

📊 Baseline (baseline) $10.5M/yr

73.0% probability / year

Normal year with October monitoring and routine incidents handled without major escalation.

seasonal October activity limited localized SCP-4683-1 discoveries no exponential amplification within a Nexus

🚨 Minor Incident $11.5M/yr

25.0% probability / year +$1.0M vs baseline

One or more significant localized episodes requiring extended response: multiple quarantines, mass detainee processing, expanded hazardous disposal, overtime staffing.

clustered SCP-4683-1 discoveries multiple SCP-4683-A detainees localized soil/ash remediation

🚨 Catastrophic Breach $160.5M/yr

2.0% probability / year +$150.0M vs baseline

Exponential amplification in a Nexus (Nx-18) requiring full-orchard demolition, mass amnestics, evacuation, and long-term remediation with national-level resource activation.

📋 Confidence Notes

Large ranges in analyst estimates, significant dependence on incident frequency and scale of chosen capital investments (e.g., aircraft purchase vs. charter, size of reserve), and the object's probabilistic/memetic effects make precise costing uncertain.
