"The men and women who put their lives on the line to protect our communities and citizens need to know they can rely on the tools they use in emergencies. New technologies are developed every day to enhance responder performance and safety, but are they durable? Will they perform under pressure? That's what the National Urban Security Technology Laboratory (NUSTL) aims to ensure. As a federal laboratory organized within the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) First Responders Group (FRG), NUSTL brings together the interests and initiatives of the Homeland Security Enterprise with the first responder community. The laboratory's mission activities in test and evaluation (T&E) and research and development (R&D) help first responders prepare, protect and respond to homeland security threats."
