Malmstrom commander outlines Sentinel upgrade, economic and family impacts for Great Falls

Colonel Daniel John Voorhees, wing commander of the 340th (Missile) Wing at Malmstrom Air Force Base in Great Falls, told the Montana Legislature’s joint Business and Labor and Economic Affairs Committee that the Minuteman-to-Sentinel modernization will refurbish 450 missile silos and is being led by a private prime contractor.

“Currently, Northrop Grumman is the prime contractor for that contract,” Voorhees said, describing the Sentinel effort as a multidecade, Defense Department–funded overhaul of Cold War–era infrastructure.

The modernization is addressing infrastructure that Voorhees said dates to the original deployment of missiles at Malmstrom. He noted the base has “put missiles on alert continuously” since Oct. 27, 1962, and described the effort as an update from analog systems to an IP‑based, digital architecture.

Why it matters: Voorhees told legislators the program has both national security and local consequences. He described the base as an economic anchor in central Montana and highlighted the community effects of construction, staffing changes and family needs during a lengthy transition.

Voorhees said the program’s scale makes cost management difficult: “We have 450 missile silos that will be refurbed. Anything times 450 is a big number,” he said. Citing post‑COVID construction inflation and a congressionally mandated recertification process, Voorhees said program costs have grown and the prime contractor is looking for “ways to save money.” He offered an illustrative example: “If it’s a million dollars that you go over budget, now you’re $450,000,000 over budget.”

Timeline and scale: Voorhees said firm scheduling remains uncertain and that program officials expect to have a clearer timeline in about a year. He described the overall transition as potentially long, noting some program estimates discussed in committee that the fielding and infrastructure work could stretch well beyond a decade: “This could be a 15 to 20 year project,” he said. He also said other wings (F.E. Warren and Minot) have started or will soon start construction and that some sites have already broken ground.

Local impacts and personnel: Voorhees described the base population and local footprint: about 3,800 active military and civilian personnel, roughly 3,289 dependents and “just over 7,100 total people associated” with Malmstrom. He said the installation’s presence makes it effectively one of the larger population centers in Montana and that construction will generate heavy traffic, many concrete and supply deliveries, and temporary increases in onsite personnel during the transition phase. He cautioned that long‑term staffing may return toward current levels after construction completes.

Military families and workforce mobility: Voorhees urged lawmakers to support policies that reduce barriers for military families, citing the Military Interstate Children’s Compact and state consideration of multiple occupational licensure compacts. He said the compact, which the transcript records as adopted by Montana in 2008, addresses eligibility, enrollment and graduation rules for students who move with military families. He also listed licensure compacts under consideration this session for dietitians, social workers, respiratory therapists and massage therapists and described licensure portability as key to improving military spouse employment and family stability.

Coordination with state agencies: Committee members asked about transportation and local readiness; Voorhees said Malmstrom is coordinating with the Montana Department of Transportation’s regional director and other state and local partners. He asked legislators to be prepared to help prioritize infrastructure work—such as bridge or road repairs—if construction traffic reveals capacity constraints.

Committee reaction and next steps: Representatives and senators on the joint committee thanked Voorhees and asked for follow‑up detail on timelines, workforce estimates and specific infrastructure needs. Voorhees invited legislators and staff to visit the base and the new facilities when available and offered to return with additional numbers as planning progresses.

No formal committee votes or actions on legislation were recorded during the presentation.
