Corrected Foundation operational one-time capital is approximately $233.1 billion (driven by stellarator/site works, ASHMORETH deployment, TENEBRAE and R&D). Recurring Foundation operational costs are ≈ $1.025 billion/year (staff, energy, maintenance, monitoring). Systemic economic impacts from potential widespread egg impacts or a visible supernova are not quantified here due to extreme uncertainty and are treated separately in notes.
🏗️ One-Time Capital Costs Total: $233.1B
Ashmoreth Satellite System $105.0B
Itemized ASHMORETH program cost estimate (total $105,000,000,000) broken down in program subcomponents: deep-space mission architecture & payload design $5,000,000,000; manufacturing of long-duration autonomous probes and relay platforms $15,000,000,000; multiple heavyweight launches and high-ΔV propulsion packages to emplace assets into Oort-region trajectories $60,000,000,000 (many individual launches / long transfer times); long-term on-orbit infrastructure and relay satellites $20,000,000,000; on-board AI/instrumentation hardware $5,000,000,000. The ASHMORETH program is itemized because it exceeds $1B and requires multi-decade mission costs and numerous launches; figures are conservative program-level estimates, not single-item rounded assertions.
Facilities $72.5B
Combined capital for the modified stellarator build (magnet structure, vacuum vessel, active cooling, radiation shielding and power conditioning) estimated at $60,000,000,000; a 1 km deep TARTARUS-Class gravitational vault at $5,000,000,000; Site-759 general hardened infrastructure at $1,500,000,000; and grid / backup power substation upgrades at $2,000,000,000. Figures derived by decomposing the original high-level ranges into plausible engineering sub-costs (civil works, specialized fabrication, heavy electrical) and summing.
Equipment $34.1B
Installed hardware and mission-critical devices: procurement of redundant Class-6 TENEBRAE engines (3 engines @ $10B each = $30,000,000,000), auxiliary plasma-energy capture and conversion hardware $2,000,000,000, exascale/simulation cluster hardware $150,000,000, and an initial rapid-response deep-space/intercept vehicle procurement allowance $2,000,000,000. Each subcomponent is listed and summed rather than presented as an undifferentiated round number.
Initial Research And Lab Setup $10.2B
R&D and prototype program for ultra-high-field magnets and exotic superconductors (materials development, prototype coils, pulsed-power test stands) budgeted at $10,000,000,000; graphite/first-wall lining initial manufacture and an on-site spare panel stockpile at $250,000,000. This line intentionally separates technology development from facility civil works.
Contingency Reserve Catastrophic $10.0B
One-time contingency reserve set aside for major rebuilds or partial catastrophic recovery operations: $10,000,000,000. Purposefully sized below speculative worst-cases; catastrophic rebuilds are handled in scenario-based surge spending (see catastrophic scenario) rather than as a single opaque reserve above $1B.
Decommissioning $1.0B
Estimated decommissioning and safe shutdown allowance for stellarator hardware, vaults and TENEBRAE systems at $1,000,000,000. This is an engineering decommissioning budget, not a speculative catastrophe payout.
Secure Curation Scp 4142 A $200.0M
Dedicated short-run shielding vault (local curation for SCP-4142-A), monitoring rigs and instrumentation for a compact high-density remnant: engineering, specialized instrumentation and shielding is budgeted at $200M. This is a practical, bounded construction compared to stellar-scale systems.
Cover Story Contingency $0
Set to $0: large-scale visible astrophysical phenomena (supernovae and mass ejection visible across large fractions of the sky) and widespread ejecta make any meaningful global concealment impossible (see RULE 3). For events that are physically impossible to conceal at global scale, the Foundation does not spend to attempt impossible universal concealment. The Foundation instead focuses on targeted, local public affairs for isolated impacts (budgeted under public_incident_response_reserve recurring) and government liaisons as operational tasks, not a global one-time concealment fund.
🔄 Annual Recurring Costs Total: $1.0B/yr
Operational Energy $300.0M/yr
Electricity and energy costs to operate ultra-high-field magnets, cryopumps, active shielding and auxiliary systems when emission capture is insufficient. This figure reflects partial recuperation in some operational periods; actual load will vary with plasma activity.
Staff Wages $160.0M/yr
Salaries and benefits for ~700 staff at an average loaded cost of approximately $225,000/year (specialist premium for high-clearance plasma/astrophysics, engineering, security, mission ops). See Personnel section for headcount breakdown.
Research And Monitoring $120.0M/yr
Operational budgets for laboratory research specific to SCP-4142 (spectroscopy, controlled extinguishing research, prototype TENEBRAE trials), plus real-time monitoring program costs that are not pure hardware O&M (data analysis teams, scientist-time, experiment campaigns). Satellite mission operations budgets are separated below where appropriate.
Logistics And Transport $100.0M/yr
Annual allowance for intercept/launch ops (on-call mission costs), specialized atmospheric capture flights, remote logistics, and routine transport of hazardous materials to/from Site-759.
Security Operations $80.0M/yr
Armed security forces, intrusion detection, anti-sabotage measures, secure transport, and periodic training exercises.
Public Incident Response Reserve $50.0M/yr
Recurring reserve to compensate affected local communities after isolated impacts, fund localized cover stories where feasible, and support short-term relocations. This is intentionally separate from 'global concealment' (which is impossible in large-scale events).
Facilities Maintenance $40.0M/yr
Ongoing magnet/cryogenics plant maintenance, structural upkeep, vacuum and active shielding upkeep. Includes spare coil replacement programs staged across years.
Covert Procurement $30.0M/yr
Ongoing covert procurement and supply-chain obfuscation for exotic components and off-book acquisitions that cannot be procured openly.
Monitoring And Archival $30.0M/yr
Long-duration archival storage, indexing and predictive modeling on large datasets (tracking candidate egg trajectories and running predictive warning systems). This is the sustained cost of the monitoring pipeline distinct from hardware depreciation.
Tenebrae Maintenance $25.0M/yr
Consumables, shielding maintenance, and test cycles for TENEBRAE annihilation/siphon systems; specialized spares and test firings.
Satellite Operations And Deep Space Comms $25.0M/yr
Day-to-day operations, telemetry relay and long-latency mission management for ASHMORETH assets once deployed; maintenance/ground stations and comms scheduling costs.
Supplies And Consumables $20.0M/yr
Consumables such as cryogens, replacement graphite panels, vacuum seals, cabling and routine parts stock replenishment.
Environmental Remediation Reserve $20.0M/yr
Operating reserve for routine contamination control, activated-material handling and smaller remediation tasks arising from limited plasma breaches.
Supercomputing Ai Operations $15.0M/yr
Power, cooling, software licensing, model retraining and data throughput costs for exascale simulation and FORC-level AI monitoring (Aijalon-class operations).
Emergency Preparedness $5.0M/yr
Evacuation drills, maintenance of shelters, and rapid relocation logistics.
Medical And Health Monitoring $5.0M/yr
On-site medical staff, occupational safety programs and long-term health monitoring for personnel exposed to radiation/plasma events.
Cover Story And Legal $0/yr
Recurring spent on public concealment set to $0 because large-scale astrophysical manifestations (supernovae, broad ejecta fields) cannot be globally concealed. The Foundation instead uses limited public incident reserves for local responses (see public_incident_response_reserve). Legal/government liaison for unavoidable disclosures occurs as operational costs absorbed in administrative staffing under staff_wages and in public incident reserves.

📋 Confidence Notes
Re-evaluation tightened itemization and applied containment-feasibility rules. Major changes relative to the original stage-2 report: (1) Global concealment/covers were zeroed per RULE 3 where astrophysical phenomena are publicly visible; (2) ASHMORETH cost was restructured into mission subcomponents rather than an unitemized single round figure; (3) catastrophic and baseline scenario costs were re-derived with explicit itemized deltas to comply with RULE 1 for >$1B figures; (4) systemic economic impacts were not assigned dollar values due to unresolvable distribution uncertainty and are explicitly left unquantified here (per RULE 2 guidance). Remaining uncertainties: technology development for sustained >250 T containment, the real-world unit cost of TENEBRAE-equivalents, and the actual fraction of ejected eggs that intersect the Solar System—these keep overall confidence at medium rather than high.
