2. DTRA History Counterproliferation Non-Proliferation WMD Threat Reduction Today Under Secretary of Defense for Acquisition, Technology and Logistics Secretary of Defense Director, DTRA Assistant Secretary of Defense for Nuclear and Chemical and Biological Defense Programs 1947 19971998 20052007 DTRA BASIC RESEARCH 2

3. DTRA safeguards the United States and its Allies from Weapons of Mass Destruction (WMD) by providing capabilities to reduce, eliminate, and counter the threat and mitigate its effects. Nuclear Weapons... difficult to acquire, devastating in use Chemical Weapons... cheap and easy to make... casualties not widespread Biological Weapons …. not difficult to find/use … attacks not quickly recognized, … casualties propagate with time Radiological Devices... dangerous to assemble with high contamination impact … low lethality High-Yield Explosives... easily available materials with many ways to deliver … point targets WMDTHREATS Providing Solutions Across the Full Spectrum of Combating WMD DTRA Mission 3

4. 4 RD-BA Directorate Focus Foster farsighted, high payoff research focused on the unique challenges to prevent, reduce, eliminate, defeat and mitigate threats from Weapons of Mass Destruction (WMD) Attract next-generation workforce Advance the fundamental knowledge and understanding in the sciences Promote university research to support WMD threat reduction Facilitate transition of research results to higher levels of S&T maturation 4

5. Impact: Near real-time support for pre-event predictions, damage assessments and strategies to remediate the effects of WMD attack (e.g. cascading failure, change in demand) Motivation and Long-Term Objectives Motivation: A WMD event will have a large geographic impact simultaneously across multiple networks causing cascading failures and decreased capacity across networks with shifting demand Objectives: Expand understanding and identify methods/strategies for the response, resilience, and recovery of interconnected networks to the extreme environments associated with WMD effects DTRA Niche: Extreme conditions over a wide area simultaneously affecting multiple networks Cascading failures across infra-structure networks “Hardening” and mitigation strategies from impacts of WMD use Current Practice: Network structure and dynamics are fairly well understood Early research into adaptive recovery of networks whose structure has changed Little to no capability to predict, prioritize or manage changed demand for remaining infrastructure capacity Physical Networks & Network Theory 5

6. One potential WMD Environment A high altitude nuclear weapon burst can produce an “electromagnetic shock wave” covering a significant portion of the United States Such geographically-large “insults” simultaneously affect networks, their interconnections, and may induce cascading failure 6
