The Department of Defense, specifically the United States Air Force (USAF), is seeking responses to a Request for Information (RFI) regarding the Secret and Below Releasable Environment (SABRE) IT Integration Service. The objective is to transition the SABRE environment from a lab-based setup to an operational production environment across four geographically dispersed government facilities, enabling continuous global collaboration among U.S. Combatant Commands, Services, Agencies, and select allies. This initiative is crucial for maintaining a secure and effective operational environment that supports various defense and interagency missions. Interested vendors must submit an email titled "SABRE-RFI INTEREST" with their company details to the designated contacts by September 23, 2024, at 0800 EST to receive Controlled Unclassified Information (CUI) related to the RFI.
