The Cooperative Threat Reduction Directorate prevents the proliferation or use of weapons of mass destruction by working with partner nations to secure, eliminate, detect and interdict WMD-related systems and materials.
Project the Agency's knowledge and capabilities in order to combat the threat of Weapons of Mass Destruction and emerging threats and to ensure nuclear deterrence.
The Nuclear Enterprise Directorate provides capabilities to the Department of Defense and interagency stakeholders, allies and partners to ensure the safety, security, reliability and effectiveness of the U.S. nuclear deterrent
force and the countering weapons of mass destruction mission.
The On-Site Inspection and Building Capacity Directorate enables the Department of Defense, the U.S. Government, and International Partners to counter and deter Weapons of Mass Destruction (WMD) by conducting Arms Control Treaty
Verification and Countering Weapons of Mass Destruction (CWMD) Building Partner Capacity Activities.
The Operations and Integration Directorate provides operational, analytical, and security support for CCMD and DTRA missions, in collaboration with FVEY and interagency partners, to achieve strategic outcomes against NDS threats
The Research and Development Directorate provides science, technology and capability development investments that maintain the U.S. military’s technological superiority in countering weapons of mass destruction & emerging threats,
mitigate the risks of technical surprise and respond to the warfighter’s urgent technical requirements.
The Strategic Integration Directorate shapes DTRA’s response to the challenges and priorities set forth in the National Defense Strategy, focusing the Agency’s operations, activities and investments in a manner that maximizes
their cumulative effect in support of our warfighting customers.
DTRA’s history is long and storied; we trace our roots all the way back to the Manhattan Project in 1947. A mission that began strictly as a weapons development program quickly adapted to include weapons effects and survivability, as
nuclear technology proliferated. During the Cold War, we turned to stockpile stewardship and hardening targets. Post-Cold War, the DTRA mission implemented non-proliferation and arms control activities, and in the 1990s began to delve
into expanded definitions of Weapons of Mass Destruction, including chemical and biological threats.
DTRA itself was established in 1998, and since that time has been entrusted with some of the Department’s most critical “emerging threat” missions. We have developed knowledge and capabilities to counter and defeat not only
chemical, biological, radiological, and nuclear threats, but matured the DoD counter-Improvised Explosive Device (C-IED) and counter-small Unmanned Aerial Systems (sUAS) portfolios as well, before transitioning them successfully to the
As technology changes – as the United States National Security landscape changes – DTRA leads the way to Detect, Deter, and Defeat WMD and Emerging Threats.
