The 21st Communications Squadron requires continued one-year functionality of Lumen’s underground copper cable infrastructure for telephone service at Peterson Space Force Base, Colorado. Lumen owns the infrastructure and is solely responsible for maintenance and repairs during telephone outages. The government intends a single-source award to Lumen as a large business under NAICS 517111, with a 1,500-employee size standard and no small-business or local-area set-asides. The procurement will use an RFQ and result in a firm-fixed-price purchase order, with performance from 27 November 2026 through 26 November 2027.
