How could the Air Force's revised Sentinel deployment plans affect Cascade County?

Possible What happens if… A possibility worth considering, not a forecast.

Revised Sentinel plans may increase permitting and local impact management for Cascade County The Air Force is revising its Sentinel deployment plans, which involve significant infrastructure changes in north-central Montana. These revisions include acquiring land for up to 30 new launch silo sites and utilizing former sites for up to 60 new launch silo sites. Because Cascade County is the administrative jurisdiction for the area affected, the county will be responsible for managing the permitting process and evaluating the environmental and community considerations of these proposed changes. The Air Force has opened a 30-day public scoping period to gather input on potential impacts before preparing the draft supplemental environmental impact statement.
