The Air Force Nuclear Weapons Center (AFNWC) is seeking information from interested contractors for the Design and Construction of the Sentinel Systems Infrastructure Launch Facilities in missile fields, associated with three (3) different Air Force Bases (AFB). F.E. Warren (AFB) located in Wyoming, with launch facilities in Colorado, Nebraska, & Wyoming. Malmstrom (AFB) located in Montana. Minot (AFB) Located in North Dakota. GENERAL SCOPE: The United States Department of the Air Force (DAF) plans to procure the replacement of the Minuteman III infrastructure launch facilities that have reached the end of their lifecycle. The Air Force Nuclear Weapons Center anticipates potential requirements for military construction (MILCON) of Sentinel Lauch Facilities located across five (5) states encompassing three (3) Air Force Bases. This requirement is anticipated to be accomplished as a Design-Build (DB) and/or Design-Bid-Build (DBB) project(s). The project execution window is currently anticipated between 2028-2040. The potential requirement may result in a solicitation issued approximately 2026. The Sentinel Ground Based Strategic Deterrent Intercontinental Ballistic Missile System Program at these AFBs include constructing 450 launch facilities across 40,000 square miles. These new launch facilities will be located within secure boundaries. Sub-surface hardened silo dimensions are estimated to be 20 feet in diameter with a depth of 110 feet and hardened sub-surface support facilities estimated to be 1,000 to 2,000 square feet to house critical equipment. Each launch facility will be permanent construction. These facilities will comply with Department of Defense Anti-terrorism/Force Protection requirements. Additionally, the hardened launch facilities will be equipped with delay and denial measures. Additional information about the program can be found in the Final Environmental Impact Statement (FEIS) which is located here: https://www.afgsc.af.mil/Sentinel/Environmental-Impact-Statement/ In accordance with Defense Federal Acquisition Regulation Supplement (DFARS) 236.204(v), the Government currently estimates the magnitude of construction for the potential project is over $500,000,000. With current estimates of magnitude of construction for each location: Between $5,000,000,000 and $10,000,000,000 F.E.
