Contractor Logistics Support (CLS) for multiple Air Force terrestrial-based air defense sensors to detect and track threats in the complex National Capital Region airspace

The Contractor Logistics Support (CLS) effort involves comprehensive sustainment of multiple U.S. Air Force terrestrial-based air defense sensors operating in the National Capital Region airspace to ensure continuous threat detection and tracking for air sovereignty and aerospace defense missions. The contractor is responsible for end-to-end lifecycle support including two-level maintenance—Organizational (O-Level) and Depot (D-Level)—as well as field and depot repairs, supply chain management, technical data package updates, obsolescence mitigation, cybersecurity compliance, and 24/7/365 operational support. Systems are classified at the SECRET level requiring the contractor to own and operate a SECRET-level facility, maintain cleared personnel with appropriate clearances, and adhere to NIST SP 800-53, the Risk Management Framework, and CMMC standards. The contractor must also support legacy non-COTS systems, manage proprietary Line Replaceable Units, coordinate with non-traditional OEMs, and transition sustainment responsibilities from prior contractors with demonstrated experience in similar technology handoffs. Performance is primarily located in Washington, D.C., with distributed support across CONUS field sites, while contracting administration is managed from Hanscom AFB, Massachusetts. The contract period is anticipated to be five years beginning January 2028, with no formal contract value published as this is currently a presolicitation for market research. The solicitation is an unclassified Request for Information (RFI) under number ESGKCLS with a response deadline of June 26, 2026. Respondents must submit a single unclassified PDF document not exceeding ten pages total, with key information including organizational size status, SAM.gov registration, cybersecurity capability, SECRET facility ownership, past performance examples, and experience maintaining classified DoD systems with legacy and non-COTS components. While no formal evaluation weights or award basis have been established, the government is seeking vendors capable of meeting stringent technical, logistical, and security demands, including system integration lab support, COMSEC and network management, quality assurance processes, and the fabrication of rare antenna components. All submissions must be emailed directly to the contracting officer and contract specialist, and the eventual contract will require full compliance with DoD security, personnel, and logistics standards without reliance on standard commercial solutions.
