  • Published
  • Air Force Global Strike Command Public Affairs

The United States Air Force is issuing this notice to advise the public of its intent to seek comments on the release of the draft Environmental Impact Statement for the Sentinel (formerly known as the Ground Based Strategic Deterrent, or GBSD) basing action and Minuteman III demilitarization at F.E. Warren Air Force Base, Wyoming; Malmstrom AFB, Montana; and Minot AFB, North Dakota. The public hearings will provide the public the opportunity to understand and comment on the potential environmental consequences of the proposed Sentinel (GBSD) weapon system, which will modernize and replace Minuteman III flight systems, weapon system command and control, and launch systems (including silos, control centers, and other ground infrastructure). It will also address Sentinel (GBSD) and Minuteman III support locations at Hill AFB, Utah; the Utah Test and Training Range, Utah; and Camp Guernsey, Wyoming.

"As the Air Force celebrates its 75th anniversary this year, the Minuteman III Weapon System has been and will continue to be integral to our Nation's defense," said Air Force Chief of Staff Gen. CQ Brown, Jr. "As we look ahead to the next 75 years, investing in nuclear modernization is as relevant as ever and we are committed to transitioning to the Sentinel, which will ensure our Nation is ready to provide strategic deterrence for tomorrow."

The public hearings will be used to further identify issues to be addressed in the environmental analysis. To effectively define the full range of issues and concerns evaluated in the EIS, the Air Force invites participation and  comments from interested local, state, and federal agencies and interested members of the public.
