The Department of Defense, specifically the Department of the Army, is seeking industry input for the development of Vital Torso Protection (VTP) ballistic armor through a Sources Sought notice. The Product Manager Soldier Protective Equipment (PdM SPE) is requesting white papers from vendors that detail their capabilities in producing a Lightweight Small Arms Protective Insert (LSAPI), focusing on two design solutions: a performance-sensitive option that meets stringent weight and ballistic standards, and a cost-effective alternative. This initiative is crucial for enhancing soldier safety and operational effectiveness, with a particular emphasis on achieving a ceramic-based solution that is lightweight and meets specific Army requirements. Interested vendors must submit their white papers, limited to 20 pages, within 45 days of the 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.
