Methodology & Data Sources

Distance: Haversine great-circle, query centroid to installation centroid · Appendix A: 31 CFR Part 802, December 2024 (219 CONUS active) · Installation coordinates: DoD MIRTA August 2025 · ICBM field counties: 90th MW (Warren AFB), 341st MW (Malmstrom AFB), 91st MW (Minot AFB) — 48 counties · County FIPS: U.S. Census Gazetteer 2025 · Research: doi.org/10.2139/ssrn.6525938

This report provides factual distance measurements against official government datasets and does not constitute legal advice. CFIUS jurisdiction depends on multiple factors beyond proximity, including transaction structure, foreign person status, and applicable exemptions. Proximity to an Appendix A installation does not automatically require a CFIUS filing; absence of proximity does not eliminate all CFIUS considerations. Consult qualified CFIUS counsel for filing determinations. This is a demonstration report for illustrative purposes only. © 2026 CFIUSCheck · cfiuscheck.com
