SCP-4456-D

Expected annual

$93.2M

One-time setup

$60.8M

Annual recurring

$92.3M

Personnel

One-time capital to build an S4 wet-dock and related infrastructure is roughly $61M; annual operations are dominated by recurring precious-metal consumption (~$66.6M) plus security, procurement overhead, maintenance and contingency, totaling ≈ $91.8M/yr. Main drivers are per-instance silver consumption, covert procurement/logistics overhead, and high-security staffing and salvage/contingency reserves.

Research And Monitoring $3.0M/yr

[#11] Ongoing scientific research & containment R&D team (3–6 researchers), lab experiments, trials and monitoring programs.

Logistics And Transport $2.7M/yr

[#6, #13] Armored transport, frequent high-value deliveries, armored watercraft ops/fuel/crew and convoy/airlift costs.

Cover Story And Legal $1.9M/yr

[#12, #21] Legal, PR, cover-company maintenance, plausible cover stories and routine payments to maintain procurement secrecy and local relationships.

Insurance And Audit $1.4M/yr

[#15] Insurance premiums on bullion throughput (~1–2%) plus internal/external audits and anti-fraud controls.

Facilities Maintenance $500K/yr

Alternative Vanish Option $0/yr

[#2] Alternative per-instance removal (≈$519,000/instance → ≈ $37,900,000/yr at 73 instances). Set to 0 in baseline because silver-consumption strategy is assumed; this field documents the alternative recurring cost if policy changed.

Long Term R And D Spend $0/yr

[#27] Multi-year R&D spend while an intensive program is active; shown as 0 in baseline (program capital shown as one-time above).

⚡ Cost Scenarios

📊 Baseline (baseline) $92.3M/yr

84.0% probability / year

Normal operational year using silver-consumption containment with routine maintenance, staffing, procurement and contingency reserves.

timely bullion provision no major breaches normal maintenance cycle

🚨 Minor Incident $93.8M/yr

12.0% probability / year +$1.5M vs baseline

Localized containment failure or delayed delivery leading to limited hostile animation, small structural damage and salvage/recovery operations.

delayed bullion shipment localized hull breach minor onboard fire

🚨 Major Breach $101.8M/yr

3.0% probability / year +$9.5M vs baseline

Significant breach causing dock damage, extended salvage and major repair work plus higher insurance/legal costs.

animated instance ramming/detonation multiple-asset collision structural failure of containment basin

🚨 Catastrophic Breach $140.8M/yr

1.0% probability / year +$48.5M vs baseline

Large-scale containment failure requiring major reconstruction, long-term environmental remediation, extensive legal/financial fallout and potential temporary relocation.

multiple simultaneous breaches catastrophic structural collapse extended site remediation and public exposure

📋 Confidence Notes

Analyst notes provide detailed line-item estimates and spawn frequency assumptions, so cost drivers are well-identified; uncertainty remains around bullion market prices, exact spawn frequency, operational policy choice (silver vs. vanish), and site-specific construction costs, yielding a medium confidence.
