The Department of Defense, specifically the United States Air Force, is seeking proposals for the development of a low-cost proximity sensor aimed at enhancing counter-unmanned aerial systems (C-UAS) munitions. The objective is to create a sensor that effectively targets both slow and fast UAS threats, including cruise missiles, with a focus on compatibility with the Advanced Precision Kill Weapon System (APKWS). This initiative is critical for improving battlefield capabilities and ensuring effective defense against aerial threats. The solicitation is currently open, with proposals due by June 25, 2025, and further details can be found at the provided source link: https://www.sbir.gov/topics/12034.
