Silent Vector

From 9/11 Encyclopedia:

October 18, 2002: CSIS (->) president and CEO John Hamre, CSIS Homeland Security Initiatives Director Phil Anderson, and Anser Institute Director Randy Larsen, will outline the initial results of a recent simulation exercise of the pre-attack phase of a credible threat to the U.S. energy infrastructure from 12:00 P.M. 1:00 P.M. on Monday, Oct. 21, at CSIS, 1800 K Street, NW, B-1 conference level, room A. 

Silent Vector, which was patterned after the 2001 Dark Winter simulated bioterrorist attack, was designed to reveal some of the most pressing issues and vulnerabilities that would arise if the nation were faced with a highly credible, but ambiguous, threat of a terrorist attack on American soil.

This two-day exercise employed a simulated National Security Council of senior policymakers, with former Senator Sam Nunn acting as president. Through the course of the game, participants, largely former senior-level government officials, were given increasingly credible and specific intelligence of a large-scale attack on the nation's critical energy infrastructure.

Silent Vector was developed and produced by CSIS in partnership with the ANSER Institute
and the Oklahoma City National Memorial Institute for the Prevention of Terrorism.
