The Defense Threat Reduction Agency (DTRA) is seeking proposals for the development of a lightweight, droppable chemical warfare agent sensor as part of its Small Business Innovation Research (SBIR) program. The objective is to create an ultra-compact device capable of real-time detection, identification, and geolocation of chemical threats, which can be deployed by uncrewed systems or individual personnel in contaminated environments. This sensor will enhance operational capabilities for Special Operations Forces by providing rapid hazard awareness and integrating seamlessly with existing systems like ATAK for real-time data visualization. The solicitation is set to open on June 25, 2025, with proposals due by July 23, 2025, and further details can be found at the DOD SBIR website.
