The Department of Defense, specifically the United States Air Force (USAF), is seeking proposals for the development of a Directed Energy Mobile Environmental Test Bed under the Small Business Innovation Research (SBIR) program. The objective is to modify an existing mobile laser propagation test bed to demonstrate longer wavelengths (between 1-10 microns) in various environmental conditions, enhancing the technology readiness level (TRL) of key components and enabling power measurement at targets up to 5 kilometers. This initiative is critical for advancing laser weapon systems and ensuring effective testing capabilities in diverse field environments. Proposals are due by June 25, 2025, with further details available at the provided source link, and the opportunity is open for both Phase II submissions, as no Phase I awards will be made for this topic.
