Welcome to DTRALink, the official Web site of the Defense Threat Reduction Agency. In the post-Cold War environment, a unified, consistent approach to deterring, reducing and countering weapons of mass destruction is essential to maintaining our national security. Under DTRA, Department of Defense resources, expertise and capabilities are combined to ensure the United States remains ready and able to address the present and future WMD threat. We perform four essential functions to accomplish our mission: combat support, technology development, threat control and threat reduction. These functions form the basis for how we are organized and our daily activities. Together, they enable us to reduce the physical and psychological terror of weapons of mass destruction, thereby enhancing the security of the world’s citizens. At the dawn of the 21st century, no other task is as challenging or demanding.

We’ve established this site to provide you with the latest and most accurate information about what we do and why we do it. I hope you’ll make use of this resource and all that it offers.
