The Department of Defense, through the Missile Defense Agency (MDA), is seeking proposals for the development of low-cost interceptors (LCIs) for missile defense as part of the Small Business Innovation Research (SBIR) program. The objective is to design and analyze concepts for LCIs that can effectively counter a range of threat missiles, including supersonic cruise missiles, short- and medium-range ballistic missiles, and hypersonic glide vehicles, while maintaining a cost-effective approach to missile defense. This initiative aims to supplement existing missile defense systems and address the cost disparity between offensive and defensive capabilities, with a target cost of $350-$700K per interceptor. Interested parties must submit their proposals by July 23, 2025, and further details can be found at the provided source link: https://www.sbir.gov/topics/12184.
