The Air Force is proposing to construct new facilities on the three installations (F.E. Warren AFB, WY; Malmstrom AFB, MT; and Minot AFB, ND), convert the Minuteman III missile alert facilities and launch facilities in the associated missile fields to the GBSD weapons system, install new utilities and communication towers within the missile fields, and establish temporary staging areas and workforce hubs. Beginning in spring of 2021, the government will begin field surveys of these areas for both biological and cultural resources to assist them in planning. These surveys would occur both on base and in the missile fields. In general, all survey work will be done by a field survey team consisting of two to four biologists or archaeologists who will walk through the survey area to identify and document potential threatened and endangered species and habitat suitable to support them, wetlands, or archaeological areas of concern. The associated tabs on this page provide details of the field survey process.
