WHO WE ARE
The Defense Threat Reduction Agency (DTRA) is the DoD Agency that confronts WMD challenges and emerging threats. Our mission is to protect the United States and its allies by enabling the DoD and international partners to detect, deter, and defeat WMD and threat networks. As both a Defense Agency and Combat Support Agency, DTRA preserves peace and prepares for uncertainty by delivering innovative capabilities, objective analysis, effective programs, and world-class expertise.
DTRA works with international partners and allies to mitigate the impact of WMD. These efforts include programs to train, exercise, engage, and build the capacity of partner nations. In particular, DTRA allied and partner engagements focus on risk reduction, nonproliferation, interdiction, border security, force protection, biosecurity, and consequence management.
A core DTRA mission is its role in implementing the inspection, escort, and monitoring provisions of key arms control treaties and agreements. DTRA’s legacy of leading on-site inspection activities includes the Strategic Arms Reduction Treaty (START), Chemical Weapons Convention (CWC), Open Skies, and New START.
