The Department of Defense is seeking a portable Aerosol Vapor Chemical Agent Detector (AVCAD) for various defense applications through a presolicitation notice. The Army, Navy, Marine Corps, National Guard, and Coast Guard require a system to detect and identify chemical hazards in tactical environments, with the ability to switch between dismounted and mounted configurations. This lightweight and compact system, weighing up to 18 pounds and fitting within a specific size constraint, must identify traditional chemical warfare agents and aerosol non-traditional agents efficiently. The request for information aims to gather market capabilities and insights into potential systems, focusing on their technical and manufacturing readiness. Respondents are asked to provide detailed system information and pricing to help the government make informed procurement decisions. No formal commitments are implied. Interested parties should contact Stacey L. Jump for more information.
