U.S. Air Force and U.S. Army Corps of Engineers leaders celebrated a project groundbreaking May 28, 2026 at Malmstrom Air Force Base, Montana. The project will serve as the “gateway” for future modernization efforts to the installation’s Minuteman III ICBM arsenal. The Commercial Entrance Control Facility has a simple but strategic purpose: enable easier and direct access for contractors and heavy construction machinery to Sentinel-related construction sites around the installation.
