The Department of Defense, through the Air Force Research Laboratory (AFRL), is seeking proposals for a ground radar system to enhance airspace situational awareness at the SkyVision Test Site in Springfield, Ohio. The procurement aims to address coverage gaps in the FAA surveillance network, particularly for low-altitude operations critical to Advanced Air Mobility (AAM), including Uncrewed Aircraft Systems (UAS) and eVTOL aircraft. The required system must provide 3-D positioning, a detection range of approximately 40 km, and remote operability, while ensuring compliance with FAA regulations and maintaining low failure rates. Interested vendors should submit their quotes by May 2, 2025, to Jason Sav at jason.sav@us.af.mil, with delivery expected within 12 months post-award.
