Terrorist Explosive Device Analytical Center (TEDAC) 

TEDAC Headquarters

The Terrorist Explosive Device Analytical Center (TEDAC) was formally established in 2003 to serve as the single interagency organization to receive, fully analyze, and exploit all terrorist improvised explosive devices, or IEDs, of interest to the United States. 

TEDAC coordinates the efforts of the entire government, from law enforcement to intelligence to military, to gather and share forensic data and intelligence about devices, tactics, techniques, and procedures—helping to disarm and disrupt IEDs, link them to their makers, and, most important, prevent future attacks. To date, TEDAC has received more than 100,000 IED submissions from more than 50 countries.

Part of the FBI’s Laboratory Division, TEDAC’s organizational structure consists of a director (FBI); a deputy director (Bureau of Alcohol, Tobacco, Firearms, and Explosives); an assistant section chief; the TEDAC Operations, Plans, and Policy Office; and eight units related to forensics, technical exploitation, intelligence, and investigations. TEDAC includes representatives from the Department of Justice, the Department of Defense, and international partner agencies who work collaboratively to address IED-related issues and develop solutions in support of the counter-improvised explosive device (C-IED) fight.

On February 16, 2016, TEDAC celebrated the completion of its new laboratory facilities at Redstone Arsenal in Huntsville, Alabama.

The mission of TEDAC is to exploit IED information and material to produce actionable intelligence to protect the United States and its international partners from terrorist attacks.

TEDAC’s Work 

TEDAC directly supports broader U.S. government efforts to mitigate or prevent IED attacks by performing advanced exploitation of IEDs through physical examination resulting in scientific and technical information and production of actionable intelligence.

TEDAC’s continued success relies on a global, whole-of-government approach to addressing the IED threat. By serving as a collaborative, single-point, advanced IED analytical center, TEDAC is able to produce actionable intelligence, make associations between devices and bomb-makers, and communicate findings to the government and its international partners in law enforcement, military, intelligence, science and technology, and border protection. In addition, through its demonstrated capability and capacity to promptly disseminate raw intelligence, TEDAC serves a key role in broader FBI efforts to acquire, analyze, act on, and share terrorist-related information.

TEDAC performs IED exploitation using both established and innovative forensic techniques in a high-capacity, multi-agency environment with experienced scientists, engineers, and technicians. Along with its existing laboratory analytical capability, TEDAC is establishing the C-IED Collaboration Center (C3). This new center will unite law enforcement, military, intelligence, scientific, and border protection partners in a physical and virtual collaborative environment focusing on global collection and IED exploitation, coordinated knowledge and data sharing, and innovative research and development designed to identify and neutralize, or eliminate, terrorists and associated threat networks.

TEDAC’s global reach is extended through the International Collection and Engagement Program (ICEP). The program furthers the FBI’s long-term C-IED strategy by building relationships with countries that could lead to the submission of IED-related material and information. The ICEP fosters these relationships by deploying special agent bomb technicians, intelligence analysts, and forensic scientists to engage and assist international agencies with their C-IED efforts. The program accounted for 44.5 percent of evidence submissions to TEDAC in 2016.

TEDAC Operations, Plans, and Policy Office 

The TEDAC Operations, Plans, and Policy (TOPPs) Office provides a variety of program and executive management support to TEDAC and corresponding units. TOPPs develops, facilitates, and manages operational and programmatic tasks, ensuring they are executed in a fiscally responsible manner while generating or furthering relationships among stakeholders within the C-IED community.
