The Department of Defense (DOD) is seeking proposals for innovative concepts in the missile defense domain for space superiority. The Missile Defense Agency (MDA) is specifically looking for advanced space sensing technologies that can improve defensive sensing capabilities against current and emerging threats. The goal is to develop and deploy a layered Missile Defense System to defend the United States, its deployed forces, and allies from missile attacks in all phases of flight. The MDA is interested in proposals that focus on advancements in sensing techniques, multi-phenomenology data fusion, and additional processing technologies to enhance birth-to-death tracking, indications and warnings, and threat discrimination. The solicitation is open for Phase I and Phase II proposals, with Phase I proposals expected to demonstrate technical feasibility and a preliminary understanding of the technology. Phase II proposals should address the need for sensing technologies that support the MDA mission, including improving data fusion, tracking capabilities, threat indications and warnings, neuromorphic processes, and intelligent discrimination of offensive targets. Phase III applications could involve providing low earth orbit communication systems and space-based processing for efficient distribution of overhead sensor data. The project duration and funding specifics can be found in the solicitation notice on grants.gov or the DOD SBIR/STTR website.
