The Department of Defense, specifically the Department of the Army, is seeking industry input for the development of Vital Torso Protection (VTP) ballistic armor, with a focus on Lightweight Small Arms Protective Inserts (LSAPI). The Product Manager Soldier Protective Equipment (PdM SPE) is requesting white papers from vendors that detail their capabilities and interest in producing a ceramic-based hard armor solution that meets specific weight and thickness requirements, while also adhering to established ballistic performance standards. This initiative is crucial for enhancing soldier safety and operational effectiveness, as it aims to refine the Army's requirements for ballistic inserts that can withstand various threats. Interested parties must submit their white papers, limited to 20 pages, within 45 days of this notice, and direct their submissions to Ms. Marianne Velez at marianne.e.velez.civ@army.mil and Ms. Theresa Quick at theresa.s.quick.civ@army.mil.
