Project Location

Malmstrom Air Force Base

Malmstrom Air Force Base (AFB) occupies 3,628 acres in northcentral Montana, approximately 5.5 miles east of the city of Great Falls, in Cascade County.

  • Malmstrom AFB is home of the 341st Missile Wing.

  • The Malmstrom missile field covers approximately 13,800 square miles across Cascade, Chouteau, Fergus, Judith Basin, Lewis and Clark, Teton, and Wheatland counties.

On-Base Elements of the Ground Based Strategic Deterrent Deployment

  • Construction and renovation of facilities, missile maintenance and security operations, and hiring additional personnel would occur at Malmstrom AFB, MT. Depending on wing sequencing, construction may start as early as 2023 and end as late as 2036.

  • Operations and missile maintenance activities would include overhauling, upgrading, and rebuilding of parts, assemblies, and subassemblies; equipment testing; and reclamation.

    • Minuteman III program personnel would transition to the Ground Based Strategic Deterrent (GBSD) program as it is deployed.

    • The GBSD program would incrementally reduce the number of on-base personnel.

Off-Base Elements of the GBSD Deployment

Construction and modernization of launch facilities (LFs) and missile alert facilities (MAFs).

  • All 150 LFs and 8 of the 15 MAFs would be modernized.

  • Approximately 7 months would be required to renovate each

LF and 12 months would be required to renovate each MAF.

  • MAFs not renovated would be dismantled and the real property would be disposed of.

Establishment of new utility corridors.

  • Approximately 761 miles of underground utility corridors and associated 16-foot-wide property easements would be established from Malmstrom AFB to and throughout the missile field.

Temporary establishment of centralized staging areas.

  • Four construction staging areas approximately 5–10 acres each would be established to reduce travel time to work sites.

  • Smaller staging areas would be established at each LF and MAF during renovation and construction of each facility.

For Temporary establishment of a workforce housing camp.

  • Barrack-style modular housing would be established to reduce travel time to work sites.

  • The housing would accommodate up to 2,000 construction workers and support personnel for 2–5 years during construction of the facilities.

  • The workforce housing camp would be fully self-supporting, including food, water, septic, and all other utilities.

Operations and maintenance activity levels for the GBSD program would be similar to levels currently supporting the Minuteman III program.

  • No change in the number of missile field personnel would occur.

Minuteman III Decommissioning and Disposal

  • Missile removal and storage is a standard procedure at Malmstrom AFB.

  • Missiles would be removed from the LFs, transported to the base for temporary storage, and prepared for transport to Hill AFB, UT; Utah Test and Training Range, UT; or Camp Navajo, AZ.

  • All Minuteman III-related components removed from LFs and MAFs would be brought to Malmstrom AFB for sorting, demilitarization, and disposal.

  • MAF surface buildings that are no longer active might be decommissioned.
