Corrected Foundation operational one-time spend is ~$2.17B (dominated by a dedicated satellite constellation and selected shelter construction), with ~ $167.3M recurring baseline operations (monitoring, staff, leased sensors, HPC, and modest R&D). The expected annual Foundation operational cost (probability-weighted) is ~$240.5M. Systemic economic impact of a full annihilation/collision event is tracked separately and is likely multi-trillion dollars (order-of-magnitude estimate $5.0T one-time, $200B/yr recurring recovery impact) and is NOT Foundation spending.
🏗️ One-Time Capital Costs Total: $2.2B
Insurance Disaster Reserve $1.0B
Dedicated Foundation-held reserve for disaster response and immediate disbursements. This is a one-time capitalization of a spendable fund for contingency payments and rapid procurement. Set at a conservative $1B baseline (see notes re systemic impacts).
Satellite Constellation Build $750.0M
Dedicated small/mid-class constellation for persistent optical/radar tracking and precision ranging. Itemized: 4 satellites (design/manufacture ~$600M), launch/commissioning ~$120M, spare parts/ground integration ~$30M. Chosen capability to guarantee higher-fidelity tracking than leased services alone.
Shelter Network Construction $300.0M
Selective hardened shelters/seed-bank/data-vault buildouts for critical personnel and assets (not planetary evacuation). Network sized for prioritized survivable subsets and continuity-of-operations, not whole-population evacuation.
Ground Tracking Network Build $60.0M
Construction of dedicated ground stations (optical/IR telescopes, radars, radomes, local telemetry links) to supplement leased services; sized for persistent decades-long operations ($20M-$200M range; conservative modest-build selected).
Medical Stockpiles $50.0M
Initial procurement of deployable field hospitals, mass-triage supplies and emergency medical caches sized for regional casualty response.
Initial Research And Lab Setup $3.0M
Initial HPC cluster procurement, licenses, modeling workstation setup and lab testbed hardware for medium-scale trajectory/Monte-Carlo ensembles.
Facilities $1.5M
Hardened exclusion/observation enclosure at Site-65: reinforced dome/hangar, remote manipulators, EMP/EM shielding, safety/perimeter works and minimal utilities. Mid-sized site buildout estimate given existing Site-65 infrastructure.
Secure Comm Infra $1.5M
Hardened high-availability encrypted links and small secure command-and-control hardware to support distributed monitoring nodes and satellite telemetry.
Equipment $1.2M
Procurement of high-resolution optical/thermal cameras, LIDAR, ultra-precise distance sensors, magnetometers/gravimeters, sealed feedthroughs, redundancy and calibration fixtures. Secure comms hardware baseline included as part of recurring secure comm operations.
Legal Structures And Shell Setup $200K
One-time legal and corporate structuring to enable opaque procurement channels and shell entities required for classified buys; does not include ongoing retainers.
Intercept And Alteration Development $0
Deliberately set to $0. Article data: all tests to date show SCP-225-1 and SCP-225-2 cannot be moved or damaged by any means known. Per containment rules, attempting to budget large intercept/alteration development as though it were feasible would be speculative and violate Rule 2. Instead the Foundation funds fundamental research (recurring research_and_monitoring) and monitoring/sheltering. If a genuinely new, demonstrably feasible method appears, a future itemized program would be costed then.
Planetary Defense Massive Geoengineering Reserve $0
Set to $0 because the article makes clear that planetary-scale alteration (shifting Earth, global mass-driver networks, etc.) is effectively infeasible or outside Foundation-only capabilities. Per Rule 2, we do not cost impossible, non-Foundation-executable interventions; realistic Foundation response focuses on monitoring, targeted sheltering, and contingency coordination with nation-states.
🔄 Annual Recurring Costs Total: $167.3M/yr
Satellite Replacement And Launch Amortization $75.0M/yr
Amortized refresh/replacement and periodic launch costs for the dedicated satellite constellation (approximate replacement/refresh cadence amortized over 10 years).
Opportunity Cost Allocation $50.0M/yr
Internal budgetary allocation representing diverted Foundation capability (space/physics assets) reallocated to SCP-225 monitoring and modeling. Treated as an operational allocation figure the O5s track; used for internal program prioritization and not an external payment stream.
Research And Monitoring $25.0M/yr
Leased sensor time (commercial/military feed contracts), baseline applied research grants into non-kinetic influence methods, HPC operations, and ongoing trajectory modeling. This funds realistic, achievable science rather than speculative attempts guaranteed to fail.
Staff Wages $7.3M/yr
Salaries + benefits for estimated permanent staff (see Personnel): research scientists, experimental techs, systems engineers, satellite/ground-ops technicians, modeling scientists, site coordinator/admin, minimal security and medical staff. Average compensation with benefits applied (headcount and role breakdown in Personnel).
Facilities Maintenance $3.0M/yr
Maintenance, utilities, site security overhead, and periodic infrastructure repairs for observation enclosure, ground stations, and selected shelters.
Cover Story And Legal $2.0M/yr
Ongoing legal retainers, PR management and limited deception operations to manage routine leak risk and procurement plausible deniability while SCP-225 poses no catastrophic public-visible event. Note: if an actual high-energy collision occurs and is widely visible, concealment becomes impossible (see Scenario notes).
Medical Maintenance $2.0M/yr
Rotation, replenishment and maintenance of medical caches and field-hospital readiness.
Logistics And Transport $1.5M/yr
Vans, aircraft charters, drones, rapid-response deployment costs, fuel, and per-diem for field tracking teams during routine operations.
Covert Procurement And Compliance $1.0M/yr
Legal/compliance costs and low-profile procurement operations to sustain classified buys and shell-company channels.
Archival Storage $500K/yr
Secure redundant archival storage and media refresh for decades of tracking and simulation data.
Supplies And Consumables $50K/yr
Consumables for instrumentation and lab testbeds, calibration services and replacement small-parts.

📋 Confidence Notes
This re-evaluation corrected prior rule violations: large-ticket (> $1B) items are explicitly itemized, and impossible-to-execute planetary-defense/intercept items were set to $0 with explanations per Rule 2. Numbers are conservative-midpoint operational estimates where feasible monitoring and contingency actions are possible. Major uncertainties remain in (a) the true physical nature/energy yield of SCP-225 collisions (article gives a minimum multi-gigaton possibility) and (b) long-run replacement cadence for space assets; these produce the medium confidence rating.
