The Department of Defense, specifically the Navy, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to optimize the materials used in the 81mm M299 Ignition Cartridge (IC) system. The primary objective is to develop a new Tube Assembly that minimizes variability in bursting strength while aligning with historical performance requirements, potentially utilizing alternative materials instead of the current sulfate paper. This initiative is critical for ensuring the reliability and precision of the ignition cartridge during operational use. Interested parties should prepare to submit proposals by May 21, 2025, with the opportunity details available on the official SBIR website.
