Continental United States Interceptor Site (CIS)

Final Environmental Impact Statement

The Final Environmental Impact Statement (EIS) evaluates candidate sites for a potential future deployment of additional ground-based interceptors for homeland defense, as required by the fiscal year 2013 National Defense Authorization Act. Consistent with the 2019 Missile Defense Review, the Department of Defense does not have a proposed action, budget authority, or direction to deploy a CIS and does not propose to deploy a CIS at this time; therefore, the preferred alternative is the “No Action Alternative” – no deployment.


The Notice of Availability (NOA) for the Final EIS was published in the Federal Register on August 30, 2019.
