Enterprise Air Route Surveillance Radar Replacement Sources Sought Request of Information

The U.S. Air Force is issuing a Sources‑Sought Request for Information (RFI) to identify industry partners capable of delivering a replacement for the legacy Air Route Surveillance Radar (ARSR‑4) across multiple fixed sites. The effort is part of the broader Air Route Surveillance Radar Replacement (ARSR‑R) program, which aims to modernize long‑range air‑traffic surveillance capabilities with advanced, reliable, and sustainable radar systems that meet FAA performance standards. The RFI is an early engagement step, seeking technical input, potential solutions, and capability statements from vendors, especially those able to handle Controlled Unclassified Information (CUI). • Goal: Replace ARSR‑4 radars with next‑generation long‑range surveillance radars at numerous sites. • Scope: Provide technical approach, system architecture, performance metrics (range, detection probability, resolution, accuracy) and CUI handling procedures. • Requirements: Submission of company name and CAFE code to obtain CUI documents; non‑U.S. entities must present export‑license proof per ITAR.
