Air Force Ground Based Strategic Deterrent Environmental Impact Statement

Welcome To The Draft EIS GBSD Website

Welcome to the Air Force's Ground Based Strategic Deterrent (GBSD) Environmental Impact Statement (EIS). As the GBSD project moves forward, this website will be updated with additional information and can be accessed anytime throughout the duration of the project.

Under the National Environmental Policy Act, the Air Force is required to conduct environmental analyses for any major federal action that is proposed to occur, to determine the environmental impact from the proposed activities, and provide the public and other stakeholders an opportunity to comment on the action and associated analyses, and to consider all alternatives. The GBSD project constitutes a major federal action, and thus an Environmental Impact Statement (EIS) must be developed. The Air Force is considering all reasonable alternatives for fulfilling the purpose and need for the action.

In the fall of 2020, the Air Force began preparing an Environmental Impact Statement (EIS) to analyze the potential effects on the human and natural environments from the deployment of the GBSD intercontinental ballistic missile (ICBM) system, and the decommissioning and disposal of the Minuteman III ICBM. The GBSD weapon system represents the continued modernization of the United States' land-based nuclear arsenal with the replacement of the aging Minuteman III. Deployment-related actions would primarily occur both on base and in the missile fields at F.E. Warren Air Force Base (AFB), WY; Malmstrom AFB, MT; and Minot AFB, ND. Additional maintenance, training, storage, testing, and support would occur at Hill AFB, UT; the Utah Test and Training Range (UTTR), UT; Camp Guernsey, WY; and Camp Navajo, AZ.
