# USAF Seeks Input for ARSR-R Radar Replacement

The U.S. Air Force Life Cycle Management Center is actively soliciting industry input for the Air Route Surveillance Radar Replacement (ARSR-R) program, which aims to modernize and replace the aging ARSR-4 radar systems deployed since the 1990s. These radar systems are critical for border and coastal air traffic surveillance, and the replacement initiative represents a significant modernization effort across multiple fixed radar sites, including locations such as Hill Air Force Base in Ogden, Utah, and Paso Robles, California.

- This solicitation signals upcoming procurement opportunities for companies specializing in radar and surveillance technologies, particularly those with experience in air traffic control and defense radar systems.
- Northrop Grumman, the prime contractor for the original ARSR-4 systems, may face competition as the Air Force seeks innovative solutions for the ARSR-R program.
- Procurement professionals should prepare for potential contract awards related to system design, development, and deployment phases, which will impact supply chain and subcontracting strategies.
- Organizations should consider aligning capabilities with the Air Force’s modernization goals to position themselves favorably for participation in this multi-site radar replacement effort.
